HVAC systems consume the most considerable amount of energy in commercial buildings and facilities. By developing and implementing a regular maintenance plan for your HVAC systems, you can stay on top of routine maintenance needs and fix issues before they become more significant problems that can positively impact your bottom line.
Use this HVAC Maintenance Checklist to ensure your heating and cooling systems continue to run as efficiently as possible for as long as possible.
- Lower Energy Costs
You can ensure that your HVAC system operates at maximum efficiency by performing preventive maintenance. According to the U.S. Department of Energy, energy bills can be reduced by up to 30%.
- Fewer Equipment Repairs
Maintaining your system extends its life, which reduces your need to spend money on an HVAC installation in the near future.
- Extended Equipment Lifespan
Commercial HVAC systems can last up to 20 years by providing proper preventive maintenance.
- Reduced Operating Costs
Keeping commercial HVAC systems in good working order can reduce operating costs by 40%. Your company’s overall costs will decrease with fewer HVAC repairs and fewer equipment breakdowns. That keeps customers happy and employees on track.
- Increased Indoor Air Quality
Airborne pollutants indoors may be two to five times higher (in extreme cases, more than 100 times higher) than those outdoors, according to the EPA.

- Develop a Maintenance Schedule
- Having a consistent schedule and sticking to it can give you a good idea of data and the condition of your systems over time.
- Follow the Prescribed Lock Out/Tag Out Procedure and use proper PPE
- Perform a Visual Inspection
- Visually inspecting and noting issues like excessive wear, rust, dirt buildups, etc., can be an excellent predictor of future maintenance needs.
- Note all System Information
- If using gauges, note operating pressures. Consider using an app that can read multiple data points to identify where potential issues may lie.
- Replace Air Filters
- Make sure to match air filters to your system specifications. Using incorrect filters can cause excessive pressures and reduce your indoor air quality.
- Check Condition of Belts and Pulleys
- Visually inspect belts and pulleys. Lubricate pulleys only if recommended by manufacturers.
- Clean Condenser and Evaporator Coils
- Dirty condenser and evaporator coils will reduce the system’s efficiency and cause it to run longer, reducing the system’s life. Consider using a system designed explicitly for coil cleaning. See a selection of coil cleaning systems here.
- Clean and Check Drainage Lines
- Condensate lines are vital pieces of healthy HVAC systems. Blockages can cause severe damage to buildings and property. Consider cleaning and treating with a biocide to limit biological growth.
- Check Electrical Connections
- Check and test electrical connections to ensure they are within tolerance and specifications.
- Check Operation of Thermostats and Other Controls
- Check the operation, and replace batteries if applicable. Consider upgrading thermostats to “smart” versions that allow building owners to adjust the environment when the areas are not in use.
- Check for Adequate Air Flow
- Generally, this can be a quick check, but using a tool like a manometer can help you get precise measurements and make adjustments to airflow for comfort.
