How Often Should Commercial HVAC Be Serviced?

You probably don’t think about your business’s HVAC system every day. It’s easy to take it for granted—until it falters. To ensure your commercial HVAC system operates at its best, how often should it be serviced? 

From energy efficiency to cost savings and environmental impact, we’ll share what goes into preventative care for commercial HVAC systems.

How Often Should Commercial HVAC Be Maintained? 

A general guideline is to perform routine maintenance at least twice a year.

However, the frequency of maintenance for commercial HVAC systems can vary depending on factors such as the type of system, the size of the facility, the local climate, and the business’s specific needs. 

Here is a suggested maintenance schedule.

Spring and Early Summer:

  • Check and replace air filters.
  • Inspect and clean evaporator and condenser coils.
  • Inspect and clean drain pans and condensate lines.
  • Check refrigerant levels.
  • Inspect ductwork for leaks.
  • Test thermostat operation.

Fall and Early Winter:

  • Check and replace air filters.
  • Inspect and lubricate fan motors and other moving parts.
  • Inspect and clean burners (for heating systems).
  • Check and tighten electrical connections.
  • Test the heating system.
  • Inspect the overall system for any signs of wear or damage.

Additionally, some components may require more frequent attention. For example, air filters may need to be checked and replaced more often, especially in environments with high dust or pollutant levels. 

Another consideration is how hard your HVAC system works. Are there large, wide-open spaces that utilize exhaust fans? Do you need a clean room for precision work? Are there rooms that must be kept at precise temperatures? What about rooms that get too hot or too cold due to your industrial processes? You may need quarterly maintenance or checks for special conditions.

These are general guidelines, and specific HVAC systems may have their own recommended maintenance schedules provided by the manufacturer. Regular maintenance helps ensure the efficient operation of the HVAC system, improves energy efficiency, prolongs equipment life, and reduces the risk of unexpected breakdowns at the most inconvenient times. Establishing a routine maintenance plan and working with a qualified team can help keep your system in optimal condition.

How Long Do Commercial HVAC Systems Last?

The lifespan of a commercial HVAC system can vary depending on the type of system, its usage, the quality of installation, and the level of maintenance it receives. Commercial HVAC systems can last anywhere from 15 to 25 years on average. 

Here are some factors that can influence the lifespan of a commercial HVAC system.

Type of system: Different types of HVAC systems have different lifespans. For example, rooftop packaged units, which are common in commercial settings, typically have a lifespan of 15 to 20 years.

Maintenance: Regular and proper maintenance is crucial for extending the lifespan of an HVAC system. Routine inspections, cleaning, and timely repairs can prevent breakdowns and ensure the system operates efficiently.

Usage and load: The frequency and intensity of HVAC system usage impact its lifespan. Systems that constantly run or experience extreme temperature variations may wear out more quickly.

Installation quality: A properly installed HVAC system is likely to have a longer lifespan. Poor installation can lead to issues such as improper airflow, which can strain the system and reduce efficiency.

Technological advances: Advancements in HVAC technology may lead to more efficient and durable systems. Older systems may become outdated and less energy-efficient over time.

Environmental conditions: The climate conditions in which the HVAC system operates can affect its lifespan. For example, systems in coastal areas may be exposed to salt air, which can accelerate corrosion.

Manufacturer and model: The equipment’s quality and the manufacturer’s reputation can influence the system’s lifespan. High-quality systems from reputable manufacturers may have a longer operational life.

Businesses need to monitor the performance of their HVAC systems, conduct regular inspections, and follow a proactive maintenance plan to maximize the lifespan of the equipment. There are high-tech ways to do this with IoT devices and sensors that deliver data wirelessly to a facility management software suite.

When a system reaches the end of its lifespan or experiences frequent issues, replacing it with a newer, more efficient model may be more cost-effective. Regular consultations with HVAC professionals can help businesses decide when to repair or replace their commercial HVAC systems.

Is HVAC Preventative Maintenance worth it? 

Yes, HVAC preventative maintenance is worth it. Regular maintenance provides several benefits that can save you money in the long run and ensure the optimal performance of your HVAC system.

Here are some key reasons why preventative maintenance is worthwhile.

  1. Energy efficiency: Regular maintenance ensures your HVAC system operates at peak efficiency. Clean coils, well-lubricated components, electrical switches and capacitors working well, and proper airflow all contribute to reduced energy consumption.
  2. Extended equipment lifespan: Routine maintenance helps identify and address potential issues before they become significant problems. This proactive approach can extend the lifespan of your HVAC equipment.
  3. Prevention of costly repairs: Small issues, if left unaddressed, can escalate into more extensive and more expensive problems. Preventative maintenance allows for the early detection and correction of issues.
  4. Improved indoor air quality: Regular cleaning and maintenance of HVAC components, such as filters and coils, improve indoor air quality. This is particularly important for commercial spaces where air quality can impact the health and productivity of occupants.
  5. Consistent comfort: A well-maintained HVAC system is better equipped to provide consistent heating or cooling throughout your facility. This is crucial for occupant comfort and can impact employee productivity and customer satisfaction.
  6. Compliance with warranty requirements: Many HVAC manufacturers require regular maintenance to maintain the warranty on their equipment. Skipping maintenance may void the warranty, leaving you responsible for repair or replacement costs.
  7. Reduced downtime: Scheduled maintenance allows for planned downtime when the system can be serviced without disrupting your business operations. 
  8. Compliance with regulations: In some jurisdictions, some rules and standards require regular maintenance of HVAC systems to ensure energy efficiency and environmental compliance.
