True Cost of Ownership: Understanding Lifecycle Costing for HVACR Systems

Wed, 04 Mar 2026 22:12:36 GMT

A Strategic Financial Framework for Long-Term HVACR Investment Decisions

For many facility leaders, HVACR budgeting conversations begin with the capital request: What does the new rooftop unit cost? What will the repair run? But commercial HVACR systems operate for decades, and the purchase price often represents only a fraction of total ownership expense. Energy consumption, preventive maintenance intensity, component replacement cycles, operational efficiency degradation, and eventual system retirement collectively determine what a system truly costs over its life.

Lifecycle Costing (LCC) shifts HVACR decisions from reactive budgeting to long-term financial strategy. Instead of evaluating systems based on first cost or short-term repair avoidance, LCC measures the total cost of ownership over the system’s service life. For facility managers overseeing multi-site portfolios, this methodology creates a structured way to forecast expenditures, justify efficiency upgrades, and make defensible capital planning decisions grounded in data rather than instinct.

What Lifecycle Costing Actually Evaluates

Lifecycle costing is not simply adding up projected expenses. It is a financial modeling approach that accounts for all costs incurred from acquisition through disposal, adjusted over time. In HVACR applications, this means evaluating how equipment performance, energy consumption, maintenance demands, and replacement timing interact financially across 15–25 years.

The critical shift is perspective. Instead of asking, “What is the lowest purchase price?” lifecycle costing asks, “Which option produces the lowest total cost of ownership while maintaining required performance?”

That broader view fundamentally changes equipment selection and capital planning strategy.

The Six Financial Components of HVACR Lifecycle Cost

An accurate LCC analysis evaluates six interconnected cost categories. Each one influences long-term budget stability.

1. Acquisition Costs

These include the visible upfront expenses:

Equipment purchase
Installation labor
Engineering and design
Controls integration
Commissioning
Permitting and inspections

While acquisition cost is the easiest number to compare, it rarely drives long-term cost performance. In energy-intensive systems, it may represent less than one-third of total lifetime expense.

2. Energy Costs

For most commercial HVACR systems, energy consumption is the dominant lifecycle cost driver.

Energy costs are influenced by:

Efficiency ratings (IEER, SEER, COP, AFUE)
Equipment sizing accuracy
Load profiles and runtime hours
Control strategies and scheduling
Climate conditions

Even small differences in efficiency compound over time. A marginally higher-efficiency unit operating across extended business hours can create substantial cumulative savings over 15–20 years - especially across multi-site portfolios.

Lifecycle costing makes those long-term energy implications visible in financial terms.

3. Maintenance Costs

Preventive maintenance is often treated as a routine operating expense, but its impact on lifecycle economics is significant.

Maintenance costs include:

Scheduled service contracts
Filter and belt replacement
Coil cleaning
Refrigerant monitoring
Controls calibration
Compliance-related inspections

Systems that require specialized labor, proprietary parts, or more frequent service may carry higher cumulative maintenance expense. However, insufficient maintenance increases energy use and accelerates component failure - increasing lifecycle cost in a different way.

An effective LCC analysis considers not only maintenance expense, but maintenance intensity and its impact on long-term asset performance.

4. Repair and Component Replacement

Over the life of an HVACR system, certain components are statistically likely to fail or require replacement:

Compressors
Fan motors
Heat exchangers
VFDs
Control boards
Refrigerant circuit components

Ignoring these predictable mid-life events skews budgeting forecasts. Lifecycle costing accounts for expected replacement intervals and incorporates them into long-term financial projections.

5. Refurbishment and Retrofit Opportunities

Some systems receive mid-life upgrades that extend useful life or improve efficiency. These may include:

Controls modernization
Economizer additions
Energy recovery upgrades
Partial system reconfiguration

A strong lifecycle model evaluates whether these upgrades meaningfully reduce total ownership cost or merely defer full replacement.

6. End-of-Life and Disposal Costs

At system retirement, costs often include:

Decommissioning labor
Refrigerant recovery
Crane rental
Disposal fees
Roof or structural remediation

While rarely discussed during purchase decisions, these costs are real and should be incorporated into long-term planning models.

Why Lowest First Cost Often Leads to Higher Lifetime Expense

Selecting equipment based solely on upfront price can produce unintended financial consequences. Lower-cost systems may operate less efficiently, require more frequent repairs, or have shorter component lifespans.

Lifecycle costing often reveals that:

Higher-efficiency equipment reduces cumulative energy expenditure significantly.
Better construction quality reduces major repair frequency.
Proper sizing reduces runtime stress and component fatigue.
Improved controls reduce energy waste and maintenance load.

Without an LCC framework, these long-term impacts are invisible during procurement.

The Financial Methodology Behind Lifecycle Costing

Lifecycle costing typically incorporates:

Net Present Value (NPV) analysis
Discount rates to adjust future costs
Projected energy escalation
Inflation-adjusted maintenance forecasting
Risk-adjusted replacement timing

This methodology allows facility leaders to compare multiple equipment options on equal financial footing. It transforms capital conversations from “higher price vs lower price” into “higher investment vs lower total cost of ownership.”

For executives under budget pressure, LCC provides a defensible rationale for selecting systems that optimize long-term return rather than short-term optics.

Energy, Maintenance, and Replacement Timing: The Three Major Drivers

Across most HVACR lifecycle models, three variables disproportionately affect total cost:

Energy performance - even minor efficiency differences compound annually.
Maintenance intensity - proactive service extends useful life and preserves efficiency.
Replacement timing - replacing slightly before catastrophic failure may reduce emergency premiums and operational disruption.

When these factors are evaluated together, LCC provides clarity on whether to repair, refurbish, or replace.

Portfolio-Level Implications for Facility Leaders

For facility managers overseeing multiple locations, lifecycle costing becomes even more powerful.

Instead of evaluating assets in isolation, LCC enables:

Identification of high-cost performers
Prioritized capital allocation
Multi-year budget forecasting
Sustainability planning
Energy performance benchmarking

This shifts HVACR from a reactive maintenance category to a managed financial asset class.

Final Perspective

Lifecycle costing reframes HVACR decision-making. It moves the conversation from purchase price and immediate repair expense to long-term financial performance. By evaluating acquisition, energy, maintenance, repair, refurbishment, and disposal collectively, facility leaders gain a realistic view of total ownership cost.

In commercial facilities, HVACR systems are among the most significant long-term operating cost drivers. Applying lifecycle costing principles enables smarter capital decisions, stronger ROI justification, and greater financial predictability.

The true cost of ownership is rarely the number on the proposal. It is the sum of every decision made over the system’s life.

Implementing Predictive Maintenance: Practical Steps for Facility Managers to Optimize HVACR Systems and Reduce Costs

Thu, 26 Feb 2026 04:49:53 GMT

Managing HVACR systems across multiple commercial sites is increasingly complex. Chains of retail stores, banks, medical offices, and campuses often operate with a mix of OEM equipment, legacy controls, and phased upgrades. Facility managers face high costs from unplanned downtime, emergency repairs, and energy inefficiencies. Predictive maintenance (PdM) provides a data-driven approach that anticipates equipment issues, extends asset life, and optimizes maintenance schedules-moving teams from reactive firefighting to proactive planning.

Predictive maintenance is not simply about installing sensors or dashboards. Its value lies in turning data into actionable decisions. Facility managers need to understand what to measure, how to interpret trends, how to prioritize interventions, and how to integrate these insights into existing maintenance workflows. PdM succeeds when combined with adoption, operational context, and effective collaboration with service providers.

1. Identifying Sensors and Monitoring Technologies

A successful PdM program starts with the right sensor infrastructure, because the quality of insights depends entirely on the quality of the data collected. Key sensor types for commercial HVACR systems include:

Temperature and humidity sensors – Track supply, return, and ambient conditions to detect gradual coil fouling, airflow issues, or refrigeration inefficiencies. Observing trends over time is more informative than occasional spot checks.
Vibration sensors – Monitor rotating equipment such as compressors, motors, and fans. Subtle increases in vibration amplitude often precede mechanical failures, offering a window to schedule repairs before emergency dispatch.
Pressure and flow sensors – Measure refrigerant pressures, pump flow rates, and filter differentials. These sensors can detect blockages, leaks, or declining system performance that reduces efficiency and increases energy costs.
Electrical current sensors – Track motor load and electrical consumption patterns. Deviations in current draw can indicate bearing wear, overloading, or failing components.
IoT-enabled meters / smart controllers – Aggregate readings from multiple sensors for centralized analysis, remote monitoring, and integration with trend analytics platforms.

Deployment considerations : Sensor placement should focus on critical and high-value equipment. Frequency of readings should capture meaningful trends without generating unnecessary noise. Standardizing sensor types and intervals across similar equipment allows cross-site comparisons, which helps detect systemic issues and optimize maintenance planning.

2. Defining Metrics and Alerts

Raw sensor data is only valuable when paired with well-defined metrics and actionable alerts. Facility managers should track metrics that reflect system health, energy efficiency, and operational risk:

Temperature and humidity deviations – Identify coil fouling, airflow restrictions, or refrigerant inefficiencies before occupant comfort is impacted.
Vibration amplitude trends – Detect early mechanical wear in motors, fans, and compressors, often months before failure.
Pressure and flow variations – Flag declining performance in pumps, chillers, or coils; small deviations can indicate leaks or restrictions.
Energy consumption patterns – Compare usage against baseline expectations to highlight overworked or inefficient systems.
Runtime and cycling patterns – Detect excessive starts/stops or unusual operating hours that could indicate control or mechanical issues.

Alert strategy: Trend-based thresholds are critical. A compressor operating within nominal limits may still be deteriorating if trends show gradual increases in vibration or temperature. By focusing on accelerating deviations, teams can prioritize interventions before failures occur, avoiding unnecessary downtime and emergency repair costs. Facility managers should also define alert severity (low, medium, high) to guide response prioritization across multiple sites.

3. Building a Predictive Maintenance Workflow

Turning sensor data into actionable maintenance decisions requires a structured workflow:

Data Collection – Sensors continuously or periodically feed performance data into a centralized platform.
Baseline Establishment – Historical data, seasonal load, and occupancy patterns are used to define “normal” operation for each unit. Baselines enable accurate trend interpretation and reduce false alarms.
Trend Analysis & Condition-Based Alerts – Analytical models highlight units showing abnormal patterns. The rate of change is often more important than a single threshold breach.
Maintenance Scheduling – Work orders are prioritized based on trend severity, criticality of equipment, and operational schedules. Scheduling proactively reduces emergency service calls.
Post-Maintenance Review – After interventions, trends are reviewed to validate repairs, recalibrate baselines, and refine alert thresholds. Continuous learning improves predictive accuracy over time.

This workflow ensures PdM converts raw data into operational decisions, reducing unplanned downtime, lowering emergency costs, and improving energy performance.

4. Partnering With Service Providers

Many facility teams rely on external vendors for HVACR service. For PdM programs, effective collaboration is essential:

Share trend data and insights – Vendors can schedule service proactively rather than reactively.
Define escalation protocols – Agree on thresholds that trigger inspections or urgent interventions.
Leverage vendor expertise – Technicians can interpret complex trends, particularly on legacy or mixed-OEM systems.
Regular reporting – Track energy use, downtime, and maintenance costs to demonstrate value and identify portfolio-wide opportunities.

A strong vendor partnership ensures predictive insights are translated into measurable operational and financial benefits, not just charts and dashboards.

5. Practical Tips for Facility Managers

Pilot before scaling : Start PdM on high-priority equipment to validate workflow, alert thresholds, and ROI.
Focus on actionable signals : Avoid overwhelming teams with unnecessary data; prioritize metrics that directly drive maintenance decisions.
Integrate with existing PM schedules : Predictive maintenance enhances preventive programs rather than replacing them.
Document baselines and trends : Historical context is essential for condition-based decision-making and continuous improvement.
Track ROI : Monitor energy savings, emergency repair reduction, extended equipment life, and avoided downtime to validate investment.

By applying these practices, PdM evolves from a technical tool into a strategic approach for managing commercial HVACR portfolios.

6. Portfolio-Level Insights and Strategic Value

Predictive maintenance provides more than site-level benefits-it offers portfolio-wide intelligence:

Energy optimization : Identify underperforming units or systems consuming excess energy.
Lifecycle planning : Trend analysis informs equipment replacement timing and budgeting, avoiding surprise capital expenses.
Cross-site benchmarking : Compare similar systems across locations to detect systemic issues, design inefficiencies, or operational gaps.
Continuous improvement : Insights allow ongoing refinement of maintenance strategies, improving predictive accuracy and operational reliability.

These portfolio-level insights help facility managers justify PdM investment to executives by demonstrating measurable impact on uptime, energy costs, and budget predictability.

Conclusion

Predictive maintenance allows facility managers to shift from reactive to proactive HVACR management. By deploying the right sensors, tracking meaningful metrics, establishing structured workflows, collaborating with service providers, and leveraging portfolio-level insights, facility teams can optimize performance, reduce costs, and protect operational continuity across multi-site operations. PdM is not just a technical program-it is an operational strategy that delivers measurable ROI while improving long-term reliability and energy efficiency.

Reliability Redefined: Turning HVACR Maintenance into a Business Continuity Strategy

Mon, 26 Jan 2026 04:28:04 GMT

Commercial HVACR systems in multi‑site retail, restaurants, convenience stores, banks, medical facilities, and other commercial chains are much more than mechanical infrastructure. They are strategic assets that directly influence customer experience, employee comfort, regulatory compliance, energy performance, operational continuity, and financial outcomes.

When HVACR systems fail unexpectedly, the impact goes beyond repair costs — it can disrupt operations, degrade indoor environments, violate compliance expectations, inflate energy use, and ultimately damage brand reputation. For facility managers and organizational leaders, standard maintenance checklists must evolve into a comprehensive reliability discipline that supports both operational uptime and broader business continuity.

Reliability as a Core Organizational Philosophy

Reliability cannot be delegated solely to technical teams. It must be embraced as a leadership priority and integrated into planning, budgeting, and risk management.

Operational Continuity & Risk Management

Commercial HVACR systems often represent a major portion of building energy use and are inherently tied to occupant comfort and safety. FacilitiesNet notes that robust HVAC maintenance can produce significant energy savings and operational improvements when performed consistently. ( facilitiesnet.com )

Leaders who treat reliability as an operational resilience strategy — rather than a cost center — are better able to:

Minimize unexpected equipment outages

Sustain indoor environmental quality

Reduce emergency operational disruptions

Optimize long‑term asset health

Bridging Facilities and Operations Leadership

A persistent organizational challenge is the disconnect between facilities teams (who speak technical metrics) and operations leadership (who measure business outcomes). To operationalize reliability:

Translate Technical Performance Into Business Impact

Rather than reporting only on maintenance completion, key performance discussions should focus on:

Service availability during peak customer hours
Effect on indoor comfort and customer satisfaction
Correlation with energy performance and cost projections
Links to safety and regulatory compliance outcomes

For example, FacilitiesNet highlights relationships between maintenance practices and performance outcomes that resonate with executive priorities, such as operational cost reductions and extended asset life. ( facilitiesnet.com )

Establishing Reliability KPIs That Connect to Meaningful Outcomes

To make reliability measurable and actionable, organizations need KPIs that map HVACR performance to business goals.

1. Uptime and Availability Metrics

Track the proportion of time essential HVACR systems are fully operational. This directly impacts comfort, safety, and business continuity.

2. Planned vs. Unplanned Maintenance

Shifting maintenance workload toward planned, preventive, and condition‑based work correlates with lower emergency interruptions and reduced lifecycle costs. Industry research shows planned maintenance programs can significantly reduce unplanned failures and operational disruptions. (achrnews.com)

3. Energy Use Intensity (EUI) and Performance Trends

Since HVACR typically accounts for a large portion of a building’s energy use, tracking EUI over time can surface performance degradation before it becomes a failure. (facilitiesnet.com)

4. Compliance and Indoor Environmental Quality

Including metrics tied to ventilation rates, humidity control, and air quality ensures that facilities maintain regulatory and comfort standards. Good documentation supports due diligence in regulatory inspections.

5. Asset Life & Lifecycle Projections

By building longitudinal performance data, facilities teams can forecast replacements and capital investments with better precision.

Scheduling, Documentation, and Communication — the Active Foundations of Reliability

Reliability is not a one‑time fix but a continuous operational discipline.

Structured Scheduling Drives Consistency

Routine maintenance must be scheduled based on equipment criticality, seasonal loading patterns, and usage intensity. Government and industry resources emphasize that regular task scheduling — including filters, belts, controls, and refrigerant checks — reduces failure risk and enhances performance. ( betterbuildingssolutioncenter.energy.gov )

Documentation Creates a Performance History

Comprehensive records create an institutional memory of how equipment performs over time. These records inform:

Condition trends
Repair histories
Part failure patterns
Seasonal load impacts

Documentation also supports compliance and audit readiness.

Communication Enables Shared Accountability

Successful reliability programs feature clear and regular communication between facilities, operations, and leadership. Sharing KPI dashboards and trend analyses keeps reliability visible across the organization.

Embedding Reliability‑Centered Maintenance (RCM)

Reliability‑Centered Maintenance (RCM) is an industry‑recognized approach that prioritizes maintenance tasks based on risk and operational impact rather than arbitrary intervals. It focuses on:

Preserving system function
Identifying failure modes
Applying maintenance strategies based on consequence severity

According to standards on RCM, it aims to “establish safe minimum levels of maintenance,” emphasizing tasks that prevent the most serious failures first. ( en.wikipedia.org )

Adopting RCM in commercial HVACR environments means:

Prioritizing work that protects business continuity
Adapting maintenance frequency based on actual condition data
Incorporating predictive analytics where applicable

This shifts maintenance from “routine service” to risk‑based reliability planning.

Leveraging Standards and Government Resources

Reliable HVACR operations are supported by recognized standards and tools:

ASHRAE Standards

ASHRAE publishes widely adopted performance and energy standards, including ASHRAE 90.1 , which establishes minimum requirements for energy efficiency and system performance in commercial buildings. Adhering to such standards informs maintenance priorities that align with performance expectations. ( en.wikipedia.org )

Government‑Hosted Resources

The U.S. Department of Energy’s Better Buildings Solution Center provides practical resources for HVACR maintenance and contracting, including best practices for preventive maintenance and performance tracking. ( betterbuildingssolutioncenter.energy.gov )

These resources help facility managers benchmark practices and align maintenance planning with recognized performance frameworks.

Technology as an Enabler — Not a Complete Solution

While technology cannot replace good process and accountability, it is a powerful reliability amplifier when integrated properly:

Condition Monitoring & Alerting

Sensors on critical components (motors, compressors, fans, coils) can provide real‑time performance insights. Alerts for trends such as temperature shifts, vibration increases, or abnormal pressures give early warning of deteriorating conditions — often before functional failures occur.

Energy Monitoring & Targeting

Tracking energy patterns over time helps detect anomalies that may signal inefficiencies or emerging malfunctions. It also helps verify that maintenance actions restore systems to expected performance levels.

Data‑Driven Decision Support

Analytics that integrate operational history with real‑time data allow facilities teams to support leadership with evidence‑based recommendations for repairs, replacements, and capital allocation.

While technology adds visibility, its value depends on integration with process, documentation, and accountability structures that align with business continuity goals.

Organizational Impact of HVACR Reliability

When HVACR reliability becomes an organizational priority instead of a siloed technical task, the effects are far‑reaching:

Leadership gains confidence in facility stability , enabling better planning for peak periods and special events.
Operations teams see reduced disruptions , resulting in smoother customer experiences and fewer emergency interventions.
Energy performance stabilizes , supporting sustainability targets and reducing operating budgets.
Asset lifecycle planning becomes data‑driven , enabling predictable capital replacement paths.

Reliability becomes part of the brand promise — consistently delivering environments that customers and employees trust.

Conclusion

In commercial environments, HVACR reliability extends far beyond quick fixes and routine maintenance. It must be:

Strategic: Embedded in business continuity planning
Measurable: Driven by KPIs tied to uptime, energy performance, safety, and compliance
Collaborative: Bridging facilities and operations leadership
Disciplined: Supported by scheduling, documentation, and communication
Standards‑Aligned: Leveraging recognized guidelines and frameworks

By redefining HVACR maintenance around reliability as a business outcome, facility managers can directly influence operational resilience, financial performance, and brand reputation — transforming HVACR systems from cost centers into strategic assets that support continuity and success.

How the HVAC Industry Is Rising to Meet the Workforce Challenge

Thu, 24 Apr 2025 19:53:20 GMT

Across the country, the HVACR industry is facing a workforce shortage that’s impacting service speed, availability, and long-term planning for commercial facility managers. According to ACHR News, approximately 25,000 HVAC technicians are exiting the workforce each year, while far fewer are entering to replace them. By some estimates, the U.S. will be short more than 100,000 skilled HVACR workers in the coming years. ¹ But while this trend has created real pressure on service delivery, the story isn’t all bad news because this one’s been on the radar for over a decade. In fact, what’s happening behind the scenes is an industry-wide transformation—one focused on attracting, training, and retaining the next generation of technicians.

As a facility manager overseeing a network of retail, restaurant, banking, medical, or other commercial properties, here’s what you should know: the HVACR industry is taking bold steps to ensure you’ll continue to have the service coverage and expertise your sites need .

Trade Schools Are Modernizing and Recruiting Earlier ²

Vocational training institutions across the U.S. have significantly expanded and evolved their HVACR programs in the past few years. Some key developments:

High School Integration: Many school districts are now working with HVACR trade associations and local businesses to integrate HVAC-focused career tracks into high school curriculums. These Career and Technical Education (CTE) programs introduce students to the trade earlier, helping shift the perception of HVAC from a “fallback” option to a high-demand, technology-forward career.
Modern Training Tools: Programs are ditching outdated textbooks. Schools are adopting HVAC simulators, remote troubleshooting tools, and digital workbenches to bring training into the 21st century. This reflects the tech-heavy reality of the job today, and appeals to younger, tech-savvy students.
Accelerated Certification Programs: Many institutions are now offering fast-track options that allow students to complete their certification and start work in as little as 6 to 12 months—often in partnership with local employers who guarantee interviews or placement.

More educators now emphasize that HVAC isn’t just about fixing ACs — it’s about smart building systems, sustainability, and technology. That message is starting to resonate.

Service Providers Are Building Their Own Workforce Pipelines ³

HVACR contractors and service companies aren’t waiting for the schools to catch up. Many are taking matters into their own hands through internal training programs, such as:

In-House Academies: Larger service companies are launching their own training schools, offering paid apprenticeships that combine classroom instruction with on-the-job experience under a journeyman-level mentor.
Onboarding Boot Camps: New hires are being immersed in 4- to 12-week intensive boot camps that cover technical fundamentals, safety, customer service, and diagnostic procedures before they ever step foot on a jobsite alone.
Upskilling for Retention: Companies are investing in continuing education and certifications for existing staff—helping technicians grow into higher-level roles (controls techs, project managers, etc.) while backfilling entry-level roles with apprentices. This creates a more stable service base and long-term bench strength.

Technology Is Extending Workforce Reach ^4 5

The next generation of techs is growing up with smartphones, apps, and instant access to information — and smart service companies are leaning into that. As a result, the HVAC industry is increasingly leaning on technology to do more with less:

Remote Diagnostics & Monitoring: IoT-connected HVAC systems allow service providers to monitor equipment in real-time, predict failures before they happen, and reduce the number of unnecessary truck rolls. This helps facilities get faster service—even in a tight labor market.
Mobile Apps & Field Support Tools: Newer technicians can now access wiring diagrams, service manuals, and expert support through AI-enabled apps, allowing them to handle complex systems with confidence—even without decades of experience.
Virtual Assistance: Some companies are equipping junior techs with headsets or video support tools, allowing senior technicians or supervisors to guide them remotely through complex repairs.

Industry Organizations Are Leading the Charge

Trade associations and nonprofits have stepped up to raise awareness and build long-term career pathways into the HVACR industry:

National campaigns aim to change public perception and promote HVACR careers to young people and parents.
Scholarship programs and grant-funded apprenticeships are being expanded, especially to reach underserved populations, women, and veterans.
National Signing Day events—similar to what’s seen in college athletics—are being held to celebrate students entering the skilled trades, giving HVACR visibility and prestige.

What It Means for Facility Managers

So, what does all this mean for those of you who manage HVACR at multiple sites and rely on vendors to deliver?

You should expect more structured and consistent talent at your service providers over time—not just seasoned veterans but well-prepared entry-level techs who are being professionally trained and supported.
Vendors who are investing in workforce development are more likely to offer predictable service, better response times, and proactive maintenance programs.
New technologies like remote diagnostics and service transparency tools (e.g., QR codes on units, live service status dashboards, etc.) are helping close the labor gap while giving facility managers more insight and control than ever before.

Because of this facility managers should:

Ask vendors how they’re developing talent. A strong internal training program is a good sign of stability and future capacity.
Explore connected systems and preventive maintenance. They help stretch labor while giving you more insight and control.
Build long-term relationships with service partners. Those who invest in your sites and your success will prioritize your needs in tight labor cycles.

The Future Looks Different—And That’s a Good Thing

The HVACR industry is undergoing a long-overdue shift in how it attracts and develops talent. While the labor shortage is real and will take time to fully resolve, the outlook is increasingly optimistic.

Rather than relying on a shrinking pool of aging experts, the industry is rebuilding from the ground up—with education, technology, and smarter training strategies at the core. For commercial facility managers, this means the service model is evolving—toward one that’s more proactive, more transparent, and more resilient. So while the labor challenges are real, the industry is meeting the moment — and that means better, more consistent outcomes for your buildings and your brand.

Prioritizing HVACR Safety

Thu, 03 Apr 2025 17:13:00 GMT

A Guide for FMs

As a commercial facility manager, you are responsible for ensuring that the HVACR (Heating, Ventilation, Air Conditioning, and Refrigeration) systems across your properties operate safely and efficiently. Whether managing restaurants, retail stores, banks, or medical facilities, your role extends beyond simply maintaining comfortable indoor temperatures—you must also safeguard employees, customers, and property from HVACR-related hazards. Many facility managers rely on third-party vendors for HVACR installation, maintenance, and repairs, but outsourcing does not eliminate safety risks. Understanding these risks and enforcing proper safety protocols can help prevent injuries, system failures, and costly damages.

The Importance of HVACR Safety

HVACR systems involve electrical components, refrigerants, combustion processes, and moving parts that pose potential dangers if not properly managed. According to the U.S. Bureau of Labor Statistics, HVACR technicians experience one of the highest rates of injury among skilled trades due to electrical hazards, falls, and exposure to harmful substances [1] . While your facility’s staff may not work directly on HVACR systems, a lack of proper maintenance or safety awareness can still put them at risk. The consequences of HVACR-related accidents can range from temporary business disruptions to severe health hazards and legal liabilities. Poorly maintained systems can also result in inefficient operation, leading to increased energy costs and shortened equipment lifespans.

Potential Hazards in HVACR Systems

To better understand the importance of HVACR safety, let’s explore some of the most common hazards:

1. Electrical Hazards

HVACR systems require high-voltage electricity to operate compressors, motors, and fans. Faulty wiring, improper grounding, or exposed circuits can result in electric shocks, burns, or fires. The Occupational Safety and Health Administration (OSHA) reports that electrical injuries account for approximately 5% of all workplace fatalities in the U.S. annually, many of which are preventable with proper safety measures ( OSHA, 2023 ).

Prevention Tips:

Ensure that only trained and certified technicians handle electrical components.
Use lockout/tagout procedures to de-energize equipment before maintenance.
Require regular electrical inspections to identify faulty wiring or overheating components.

2. Refrigerant and Chemical Exposure

HVACR systems rely on refrigerants such as R-410A or R-32, which can be hazardous if leaked. Exposure can cause dizziness, nausea, respiratory issues, and, in extreme cases, asphyxiation. Additionally, some cleaning agents and coil cleaners contain caustic chemicals that can cause skin burns or eye injuries.

Prevention Tips:

Ensure refrigerant leaks are promptly detected and repaired.
Provide technicians with proper protective gear, including gloves and goggles.
Store and dispose of hazardous chemicals according to EPA guidelines ( EPA, 2023 ).

3. Indoor Air Quality and Respiratory Risks

Poorly maintained HVACR systems can circulate airborne contaminants, including mold spores, dust, and bacteria. This can lead to Sick Building Syndrome (SBS), increasing employee absenteeism and lowering productivity. The CDC emphasizes that inadequate ventilation and air filtration contribute to the spread of airborne illnesses, including influenza and COVID-19 ( CDC, 2023 ).

Prevention Tips:

Regularly clean and replace HVAC filters.
Inspect and clean ductwork to prevent mold and bacteria buildup.
Monitor carbon monoxide levels in facilities with gas-powered heating systems.

4. Physical and Fall Hazards

Many HVACR components are located on rooftops, requiring technicians to work at elevated heights. Falls from ladders and rooftops are among the leading causes of workplace fatalities in the U.S. OSHA reports that falls accounted for 35% of all construction-related deaths in 2022 (OSHA, 2023).

Additionally, technicians may suffer musculoskeletal injuries from lifting heavy compressors, motors, or ductwork.

Prevention Tips:

Ensure that all technicians use fall protection equipment when working at heights.
Implement proper ladder safety training.
Provide lifting equipment such as hoists or cranes for heavy components.

Types of HVACR-Related Injuries and Their Impact

The hazards outlined above can lead to various injuries, some of which can be severe or even fatal. According to OSHA, the most common HVACR-related injuries include:

Electrical burns and shocks – Result from faulty wiring or contact with live circuits.
Refrigerant burns and poisoning – Occur due to improper handling of chemicals or exposure to refrigerant leaks.
Respiratory issues – Caused by exposure to mold, carbon monoxide, or chemical fumes.
Falls and fractures – Result from working on rooftops or lifting heavy equipment without proper precautions.

Each of these injuries can lead to significant medical expenses, workers’ compensation claims, and potential liability for your company if safety protocols are not enforced.

How Facility Managers Can Prevent HVACR Safety Incidents

While you may not be directly performing HVACR work, you play a key role in ensuring a culture of safety within your organization. Here are some steps you can take:

1. Partner with Safety-Conscious Vendors

When selecting an HVACR service provider, prioritize vendors that emphasize safety. Ask about their safety training programs, OSHA compliance, and history of workplace incidents.

2. Perform Regular Safety Audits

Routine inspections can help identify potential hazards before they lead to accidents. Conduct regular site visits to ensure hazards are addressed and safety protocols are accurate.

3. Establish Clear Emergency Protocols

Every facility should have an emergency response plan in case of HVAC-related incidents, such as refrigerant leaks, fires, or electrical failures. Train facility staff on how to respond appropriately.

4. Stay Updated on HVAC Safety Regulations

OSHA, the EPA, and ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) regularly update safety standards. Staying informed on these regulations helps ensure compliance and reduces liability.

Conclusion

As a facility manager, you are not just responsible for keeping HVACR systems operational—you are responsible for ensuring they operate safely. Neglecting HVACR safety can lead to severe health risks, costly property damage, and potential legal repercussions. By working closely with qualified vendors, enforcing safety standards, and educating your staff, you can create a safer environment for your facilities, employees, and customers.

The Role of Humidifiers and Dehumidifiers in Commercial HVAC

Thu, 10 Oct 2024 14:17:00 GMT

Managing HVAC systems across a chain of commercial properties involves more than just heating and cooling. Two critical, yet often overlooked components are humidifiers and dehumidifiers. Whether you are well-versed in HVAC or completely new to these systems, understanding how these devices work, why they’re important, and how to maintain them can significantly impact the comfort and efficiency of your commercial properties.

What Are Humidifiers and Dehumidifiers?

Humidifiers add moisture to the air. In commercial HVAC systems, this is typically done through evaporative, steam, or ultrasonic means. These systems release water vapor into the air, increasing the relative humidity in spaces where the air may be too dry, especially during winter months when heating systems tend to dry out the air.
Dehumidifiers , on the other hand, remove excess moisture from the air. This is crucial in environments with high humidity, particularly in warm, coastal, or southern climates where moisture levels can cause discomfort, mold growth, or even damage to equipment and structures. Commercial dehumidifiers are often integrated into HVAC systems and use refrigeration coils to condense water vapor from the air.

Why Are Humidifiers and Dehumidifiers Important?

The primary goal of any HVAC system is to maintain a comfortable and healthy indoor environment. While temperature control is the most obvious aspect of this, humidity control is equally important. The right balance of humidity (typically between 30% and 50%) impacts both human comfort and the integrity of your building’s infrastructure.

Why you need a humidifier:

Comfort and Health: In environments where the air is too dry, occupants can experience dry skin, irritated sinuses, and increased susceptibility to colds and other respiratory issues.
Preservation of Materials: Low humidity levels can cause wood, fabrics, and electronics to become brittle or damaged.
Static Electricity: Dry air leads to a buildup of static electricity, which can be problematic for electronics and create discomfort for occupants.

Why you need a dehumidifier:

Prevent Mold and Mildew: High humidity levels can lead to mold growth, which is not only damaging to property but also a health hazard.
Equipment Protection: Excess moisture can cause corrosion and damage to electronic systems and equipment.
Improved Air Quality: Dehumidification helps remove allergens, dust mites, and other particulates from the air that thrive in damp environments.

Common Failures and Causes

Like any component of an HVAC system, humidifiers and dehumidifiers can experience failures. Understanding potential issues can help prevent downtime and costly repairs.

Humidifiers:

Water Supply Issues: A common failure point is the water supply. Blockages or issues with the water line can prevent the system from generating humidity.
Mineral Buildup: If the water used is hard (high in mineral content), lime and calcium deposits can clog the system, reducing efficiency and possibly causing damage over time.
Controller/Actuator Failure: The sensors or controllers that regulate humidity can fail, causing the system to either over-humidify or not work at all.

Dehumidifiers:

Refrigerant Leaks: Dehumidifiers often rely on refrigerants to cool the air and condense moisture. A refrigerant leak can cause the system to lose its ability to remove moisture.
Clogged Drain Lines: The moisture removed by dehumidifiers must go somewhere, and usually, it drains through a dedicated line. If this line becomes clogged, water can back up into the unit, causing damage.
Compressor or Fan Failures: The compressor, which cools the air, and the fan, which moves air through the system, are mechanical components that can fail with time and heavy use.

How to Maintain Humidifiers and Dehumidifiers

Proper maintenance of humidifiers and dehumidifiers can prolong their life, prevent costly repairs, and ensure your HVAC system runs efficiently.

Humidifiers:

Regular Cleaning: Clean water tanks and replace filters regularly to prevent mold and mineral buildup.
Water Line Inspections: Check water lines for blockages or leaks and ensure water flow is uninterrupted.
Monitor Humidity Levels: Ensure the system is set to maintain proper humidity levels, and calibrate the sensors as needed.

Dehumidifiers:

Clean the Coils: Dirty or blocked coils can reduce the dehumidifier’s ability to condense moisture. Clean them regularly for maximum efficiency.
Check and Clean Drain Lines: Ensure the drain lines are clear and free of obstructions. Periodically flushing the lines can prevent clogs.
Inspect the Refrigerant Levels: Regularly check for refrigerant leaks and recharge the system as needed to keep the dehumidifier working properly.

Conclusion

Humidifiers and dehumidifiers play a vital role in maintaining the comfort, health, and safety of your commercial properties. A well-maintained system not only provides a more comfortable environment for occupants but also protects the building’s infrastructure, equipment, and materials. Whether you’re new to HVAC or have some experience, understanding these components and keeping them in good working order is essential for your role as a facility manager.

By taking a proactive approach to maintenance, you can avoid the common pitfalls that lead to costly repairs and downtime, ensuring that your properties remain comfortable, safe, and efficient year-round.

Understanding Chilled Water Air Handlers: A Vital Component of Commercial HVAC Systems

Mon, 09 Sep 2024 15:37:48 GMT

In the realm of commercial HVAC systems, chiller water air handlers play a crucial role in maintaining indoor comfort and operational efficiency. Whether you're familiar with HVAC systems or just starting to learn, understanding chilled water air handlers is essential for effective facility management.

What are Chilled Water Air Handlers?

Chilled water air handlers are units in HVAC systems that circulate cooled air throughout a building. These units utilize chilled water, which is typically provided by a chiller, to condition the air before it is distributed throughout the space.

Components of a Chilled Water Air Handler:

Blower Unit: Moves air through the system.
Chilled Water Coils: The coils contain chilled water that absorbs heat from the air, cooling it down.
Filter Section: Cleans air of dust and particulates before circulating it.
Mixing Chamber: Regulates the temperature and humidity of the air.

What Do Chilled Water Air Handlers Do?

The primary function of chilled water air handlers is to distribute cooled air throughout different parts of a building. Here’s how it works:

Air Circulation: The blower unit draws air from the building into the air handler.
Temperature Regulation: The air passes over the chilled water coils, where heat from the air is absorbed, reducing its temperature. Conversely, during heating seasons, these coils can be used to heat the air.
Humidity Control: The mixing chamber adjusts humidity levels to maintain a comfortable environment.

Why Are Chilled Water Air Handlers Important?

Chilled water air handlers are vital for several reasons:

Energy Efficiency: They help regulate temperature efficiently, which can significantly reduce energy costs, especially in commercial spaces.

How Do Chilled Water Air Handlers Differ From Chillers?

While chilled water air handlers and chillers work together in an HVAC system, they serve distinct functions and are used in different types of facilities:

Chillers: A chiller is a large piece of HVAC equipment that removes heat from a liquid, typically water, via a refrigeration cycle. The chilled water produced is then circulated through pipes to air handlers or other cooling units within the building.
Chilled Water Air Handlers: These units take the chilled water and use it to cool the air circulating through the building. They are responsible for distributing this conditioned air to occupied spaces.
Key Difference: The chiller is a central cooling unit responsible for producing chilled water, whereas the chilled water air handler is a distributed unit that uses this chilled water to cool and distribute air throughout specific areas of a building.

Types of Businesses Using Chilled Water Air Handlers vs. Chillers

Businesses Using Chilled Water Air Handlers: Retail stores, restaurants, office buildings, and smaller commercial spaces typically use chilled water air handlers. These businesses benefit from the efficient and localized cooling that chilled water air handlers provide without the need for large-scale chillers.
Businesses Using Chillers: Hospitals, large manufacturing facilities, and data centers are more likely to use chillers. These buildings require robust cooling systems to manage large cooling loads across extensive or densely populated areas. The size and capacity of chillers make them suitable for these environments.

How to Maintain Chilled Water Air Handlers

To ensure optimal performance and longevity of chilled water air handlers, regular maintenance is crucial:

Filter Replacement: Clean or replace air filters regularly to prevent dust and debris buildup, which can impair air quality and strain the system.
Coil Cleaning: Periodically clean the chilled water coils to remove dirt and grime, which can reduce cooling efficiency.
Inspect and Lubricate Motors: Check motor bearings and belts for wear and tear, lubricating them as needed to prevent friction and extend lifespan.
Monitor Water Flow and Temperature: Ensure that the chilled water is flowing properly and at the correct temperature for efficient cooling performance.
Professional Inspections: Schedule routine inspections by HVAC professionals to identify and address potential issues before they escalate.

Conclusion

Chilled water air handlers are indispensable components of modern commercial HVAC systems, providing efficient cooling while enhancing indoor air quality and comfort. By understanding their role, recognizing how they differ from chillers, and implementing proper maintenance practices, facility managers can ensure reliable performance and optimal energy efficiency, benefiting both their business operations and the well-being of occupants.

Why & When Coil Cleanings Matter

Mon, 10 Jun 2024 15:27:05 GMT

The Importance of Evaporator and Condenser Coil Cleaning in Commercial HVAC Systems

As facility managers, you understand the critical role HVAC systems play in maintaining comfortable and safe environments. However, without a technical background in HVAC service, of ten the nuances of system maintenance, such as evaporator and condenser coil cleaning , can be challenging to navigate. This article aims to review the process, explaining why the se cleaning s are crucial, what the y entail, and why the frequency of cleaning should be tailored to specific conditions rather than a rigid annual schedule.

Why Coil Cleaning Matters

Energy Efficiency: Dirty coil s impede heat transfer, forcing the HVAC system to work harder to achieve the desired temperature. This in creased workload results in higher energy consumption and elevated utility bills. Clean coil s enhance the system's efficiency, leading to cost savings and reduced environmental impact.
System Longevity: Accumulated dirt and debris on coil s can cause undue strain on the HVAC system, leading to more frequent breakdowns and a shorter overall lifespan. Regular cleaning helps maintain optimal system performance, preventing costly repairs and premature replacements.
Indoor Air Quality: Clean coil s contribute to better in door air quality by reducing the amount of dust, mold, and bacteria circulated through the air. This is particularly important in environments where air quality directly affects health, such as in retail stores, of fices, and restaurants.

The Cleaning Process

Evaporator Coils are located in side the air handling unit or attached to the furnace, evaporator coil s absorb heat from in door air. Over time, the se coil s can accumulate dust, dirt, and biological contaminants.

Condenser Coils are located outside the building, condenser coil s release the absorbed heat in to the outdoor air. The y are exposed to outdoor elements and can become clogged with leaves, dirt, and other debris.

While located in different areas, cleaning the se coil s in volve a similar process:

Shutting Down the System: The HVAC system is powered down to ensure safety.
Accessing the Coils: Technicians will remove panels or covers to access the coil s.
Inspection: A thorough in spection identifies the level of contamination and any potential damage.
Removing Debris: Large debris is manually removed from the coil s.
Cleaning: Depending on the coil material and level of dirt, appropriate cleaning agents may be applied. The se can range from mild detergents to specialized coil cleaners. Other times cleaning s can be done with just the use of a brush or the coil s cab be rinsed with water to remove debris.
Final Inspection: The coil s are in spected for cleanliness and damage, the unit is reassembled and the system is restarted.

Determining Cleaning Frequency

While annual coil cleaning is a common recommendation, it is not a one-size-fits-all solution. In fact, many companies assume an annual cleaning schedule is necessary, but this isn't always the case. Making this assumption without consulting with your HVAC vendor can lead to unnecessary expenditures. Several factors should in fluence the cleaning schedule:

Type of Work Done On-Site: Facilities that generate high levels of airborne particles, such as manufacturing plants, automotive shops, or bakeries, may require more frequent coil cleaning . In contrast, buildings with minimal dust and contaminants can of ten extend the period between cleaning s.
Geographic Location: Coastal areas with salty air, urban environments with high pollution levels, or regions with heavy pollen seasons will necessitate more frequent coil cleaning s to prevent corrosive and obstructive buildup.
Local Weather Conditions: Areas with extreme weather conditions, such as high humidity or significant temperature fluctuations, can accelerate coil contamination. For in stance, high humidity can promote mold growth on evaporator coil s, while dust storms can quickly clog condenser coil s.

Discussing Cleaning Needs with Your HVAC Vendor

It is crucial to discuss the specific needs of your facilities with your HVAC vendor rather than adhering to a default annual cleaning schedule. A qualified HVAC professional can assess your system, consider the environmental and operational factors unique to each of your locations, and recommend a tailored maintenance plan. This approach ensures you are not spending money on unnecessary cleaning s and that your system receives maintenance precisely when needed.

Conclusion

Understanding the importance of evaporator and condenser coil cleaning and tailoring the frequency to your facility’s specific conditions can optimize your HVAC system's performance and longevity. By partnering with experienced HVAC professionals who can assess and recommend appropriate cleaning schedules, you ensure a comfortable, efficient, and healthy environment for your commercial spaces.

Avoid Burst Coils

Wed, 17 Apr 2024 16:20:00 GMT

It is not uncommon for buildings to be heated and cooled out of a building central plant. The ce ntral plant makes hot or cold water that is piped around the building. There is a common point of failure that can cause substantial damage to the building and its contents. That risk can be mitigated when the people maintaining the air handlers are made aware of the potential situation.

Normally, in areas that experience cold weather, the central plant only operates the chillers to provide cooling when the temperature outside is above a set point. If cooling is needed when it's cooler outside, outside air is brought in to cool the space. That presents the potential point of failure. If freezing outside air is allowed to enter the water-filled coil, the coil can freeze and burst.

When a coil freezes and bursts, there is the potential for a lot of water to flow from the unit. In a worst-case scenario, the flood can destroy a store, and the space below it when it happens at night. There are several potential reasons for why freezing air would be allowed to enter the water-filled coil.

Dampers can freeze in place if not lubricated. The controls can fail leaving the dampers fixed in place.
Sensors can be installed in the wrong place; controls can be adjusted badly and, in some cases, disconnected altogether.
Freezestats are installed to protect against these potential problems. However, they can be installed in the wrong place or set improperly. Technicians can reset tripped freezestats and put the unit back into service without resolving the problem.

Another not-common problem is that there are units installed with no mixing box. A mixing box is where the outside air is mixed with return air to maintain a return air set point well above freezing but cool enough to cool the space. When there is no mixing box, freezing outside air can enter the coil unmixed and freeze the coil. This problem is made worse by the fact that moving these pieces, once installed, is unlikely to be done.

The only practical solution to any of these problems becomes either locking-out the outside air or draining the coils of the water for the winter or until the problem is resolved. It takes a skilled and informed workforce to reliably detect these issues and react to them appropriately. The result of failing to do so can be disastrous.

About Brownouts and Single Phasing

Fri, 05 Apr 2024 16:35:22 GMT

Brownouts and single phasing are terms used to describe common problems with the power entering a machine or a building. They are a common cause of compressor failures in commercial air conditioners.

Brownouts

A brownout is when the voltage being delivered drops below the minimum acceptable voltage.

The industry standard for judging the acceptability of the incoming voltage is that it should be no more than 10% above or below the air conditioner's nameplate voltage. For example, it would be very common in the United States to have a nameplate voltage called 208-230 volts. That means that the acceptable voltage range for that kind of unit would be 90% for 208v on the low end and 110% of 230v on the high end. This means the 187v-253v is the acceptable voltage range for a 208v-230v unit. If the incoming voltage is less than 187 on any of the three incoming power lines, it would be described as a brownout. When this problem occurs, it's almost always a utility company problem. Running equipment with a low voltage shortens the life of electric motors and may make the equipment unreliable.

There is a related problem called voltage imbalance. For air conditioners, the three incoming power lines should all have voltages within 2% of their average. If the voltage of the power line with the greatest difference from the average of the three voltages, is different by more than 2%, it is called imbalanced or unbalanced. This is sometimes caused by an unbalance of the electrical loads in the building. Running equipment with a voltage imbalance shortens the life of electric motors.

Single Phasing

Single phasing happens in commercial applications where three-phase power (i.e., when the machine is powered by three incoming power lines) is common. If one of those lines has no power while the other two do, it's called single phasing.

Single phasing is a critical failure of the power to the motor. It will often result in blown fuses. A machine that runs under single phase conditions will burn out motors in a short time.

What do we do when we are faced with one of these problems?

The first thing to do is to determine if the problem is isolated within the machine, or if the incoming power to a machine or to the building is a problem. If the incoming power to the building is a problem, the first thing to do is shut off the power to all the equipment in the building. Leave it off to prevent damage to the equipment until the correct power is available to them. Next, someone must call the power utility. They will resolve it.

When these problems are limited to power to one air conditioner, it means that there is a problem in the circuit braker panel or the wire running the unit. An electrician could be called to resolve that issue. They would be replacing a fuse or circuit breaker or repairing a wiring connection problem.

When the problem is within the unit, it would be a fuse, terminal block, contactor, or wiring connection problem, usually burnt wiring. An HVAC technician would resolve these problems.

In areas that experience brownout or single phasing with their incoming building power, It is possible to protect equipment. A device called a "Phase Monitor" is the standard solution to repeated incoming power episodes. The phase monitor watches both the voltage and for a loss of a phase, and will shut the unit off as a safety control.

To see if a phase monitor would be a viable solution for you, contact #HeliosServicePartners.

Why do compressors in air conditioners fail?

Mon, 18 Mar 2024 16:46:19 GMT

Compressors don't generally wear out. They fail because they are forced to run under conditions that inevitably lead to their failure. While there are many potential failure modes, by far the most common classes of failures are mechanical and electrical. To put it another way, there can be problems with the compressor or problems with the motor that drives it. Motor problems are sometimes caused by compressor problems.

Mechanical failures include "locked rotor compressors" and "inefficient compressors".

Locked rotor compressors are, simply put, compressors that are locked, i.e. the motor cannot turn it. The primary cause of locking is the loss of lubrication to the bearings. Liquid refrigerant is a very effective degreasing solvent. When liquid refrigerant enters the crankcase of the compressor and is pumped into the bearings, it cleans away the lubrication and the compressor can lock up. Running an air conditioner too cold allows liquid refrigerant into the compressor. Every compressor has a nameplate which includes a value called Locked Rotor Amperage or LRA. The diagnosis of a locked rotor compressor is the motor pulling LRA as measured with a current meter.
Inefficient compressors are compressors that are turning but pumping less than it should. This happens when there are broken parts inside the compressor. An air conditioning compressor is designed to pump refrigerant vapor. The compressor is not made of materials that can stand up to the forces required to compress liquid refrigerant. Running an air conditioner too cold can allow liquid refrigerant to enter the compressor. The diagnosis for an efficient compressor is the low side pressure is too high and the high side pressure is too low.
Both locked rotor and inefficient compressors are caused by liquid refrigerant entering the compressor. This commonly happens when there is too little heat being absorbed in the evaporator coil. This can be caused by an indoor fan failure, or the filters or evaporator coil being plugged with dirt, or an airflow restriction in the ductwork.

Electrical failures include "shorted" and "open" motor windings which describe two different types of damage to the motor windings.

Open windings means that somewhere in the bundle of wire that is the motor windings, it broke apart for some reason.
When motor windings are shorted, it means they broke apart and are now touching something they should not.
There are two common causes for motor winding damage: 1) either it ran too hot and the wires melted, or 2) the windings were damaged in some way, often by broken metal parts gashing them.
The diagnosis is to measure the motor winding resistance in ohms. Open means infinite ohms winding to winding as it will pull no power. Shorted means zero ohms to ground as it will blow fuses.

There is a common compressor failure mode is called a “Burn out”. The cause is, as the name suggests, the compressor overheated. It will include shorted or open windings. It will also include black ash distributed around the inside of the system. You will notice it when you access the refrigerant, if any is left in the system. A compressor can overheat when the motor draws a lot of power but does not use it to turn the compressor. This can include locked rotor compressors. It can also include incoming power problems like low voltage or the loss of one phase of power. A compressor can also overheat if it is not properly cooled. A compressor is cooled by the cold refrigerant entering it. If the compressor is forced to run with returning refrigerant that is not cool for any reason, including loss of charge or a refrigerant flow restriction, the motor winding can overheat and fail.

Most compressors run for a long time. When they fail, it’s important to find and resolve the cause of the failure before it kills the compressor. It’s sometimes not possible to determine the cause of a compressor failure until after the replacement compressor starts and runs. Safety controls, like high and low-pressure switches, freezestats, phase monitors, and even low ambient lockouts are sometimes installed to prevent compressor failure by shutting the compressor off when adverse conditions exist. Regular maintenance is used to detect degrading low side heat transfer as it is developing. That sometimes gives the opportunity to resolve it prior to a comfort complaint or a compressor failure.

Why Are Some Areas Hot and Others Cold?

Wed, 06 Mar 2024 16:55:15 GMT

There are many potential reasons as to why some areas in a building may be too warm while others are cooler or even frosty. Each case needs to be evaluated individually.

The most common reason might be that one or more heating, ventilating and air conditioning (HVAC) units are non-functional. However, this is not the only possibility and there are some broader categories of common reasons these complaints are made. Other potential reasons include:

Control problems - Meaning a non-functional control system, setpoint and schedule issues, or sensor placement or calibration issues.
Air distribution problems - Meaning restricted or excessive supply airflow into some parts of the space, insufficient return air access, or duct leakage.
Building use issues - Meaning one area may have open doors to the outside vs another area with high internal heat gains from equipment or people.
Design issues - Meaning inappropriate or missing equipment or ductwork, or unanticipated changes to the area’s use.
Personnel issues - Meaning disagreement with the corporate setpoint or disagreement among occupants of the space as to what is comfortable.

Determining the root problem is an important step towards resolving the problem. It is not uncommon to have more than one problem simultaneously. A skilled and experienced HVAC service technician will follow a process to detect and diagnose the range of potential issues.

Why do evaporator coils freeze in an air conditioner? The short answer is because the evaporator coil gets too cold reaching less than 32°F. What would cause an evaporator coil to be so cold? The two common causes for that are either the coil cannot absorb enough heat, or the unit is low on refrigerant.

A coil is not absorbing enough heat could be the result of the following:

Too little airflow, which can be caused by plugged filters, a blower or blower motor problem, or a ductwork restriction.
The coil is plugged with dirt, which is usually a sign of deferred maintenance.

A unit that is low on charge will not have enough refrigerant flow to keep up with the compressor’s pumping capacity. That would cause the pressure in the evaporator to go too low as well. Low pressure produces low temperature when there is liquid refrigerant present. So, where the refrigerant enters the coil, it gets too cold, and it freezes the condensed water on the outside of the coil. The frozen area creeps across the coil and eventually can freeze the compressor in ice.

Another question that could be asked is “why do we care if the coil freezes?”. The obvious answer is that a frozen coil will no longer pass air so there will be no cooling delivered to the occupied space. In addition, when the coil thaws, it causes a water leak under the unit. The less obvious but probably more important reason to care is that the system needs to absorb heat in the evaporator to vaporize the liquid refrigerant. A frozen coil cannot do this. Because of that, liquid refrigerant can enter the compressor. This is one of the more common reasons for compressor failure. Replacing compressors are among the more expensive service tasks and the unit will be non-functional for a while. Failed compressors are among the most common reasons units are replaced on an emergency basis.

Changing filters and checking the condition of the blower regularly is the way to prevent frozen evaporator coils.

HVAC Unit Replacement Planning

Mon, 19 Feb 2024 19:45:01 GMT

HVAC unit replacement planning is typically part of the annual budgeting process. The question to be considered and answered is this: Where do we spend our limited capitol replacement budget to achieve the best effect? Meaning, when requesting a capitol budget, how much do you ask for and what data do you need to bring to validate the request. Because organizations are resourced differently and may have various levels of deferred maintenance, well as different goals and priorities, any unit replacement plan will have to reflect those realities. The approach described below could be used as template for a larger multi-unit organization.

Any good plan starts with good information about the subject. In this case the HVAC units. When working with large fleets of HVAC units and prioritizing their replacement, a systematic approach is very useful. A small number of common data points can produce an effective prioritized list of replacement opportunities and data points used may include:

each unit’s age
perceived reliability
the impact a unit failure would have on the operation of the business
condition assessments
performance assessments
design energy efficiency
parts availability

Such data points can be collected in a systematic way by a technician during a scheduled maintenance inspection. In addition, simple apps to collect such data and populate a cloud database are readily available.

An effective approach to analyzing the collected data might be to assign a score for each assessment and a factor for how important it is. A list that first focuses on age, condition and performance of the systems may be created. Perhaps age could be factored at 2x the other variables. Then the final scores may be ordered from best to worst. Discard the top 2/3 of the list and concentrate on the remaining, badly scoring units. Call this the bottom 1/3 list. Then that list can be reordered based on the business impact and the perceived reliability of the units for example.

If the expected usable life of a unit is 15 years, then 1/15th of all the units would be scheduled for replacement each year. There are reasons why some units that really should be replaced may not be replaced. An example of this might be a short time to the end of a lease.

To produce a list with twice as many candidates as there are replacement opportunities, in order to give sufficient choices, we can select the bottom 40% of the reordered bottom 1/3 list. This becomes our list of prioritized replacement candidates.
