Performing Maintenance On HVAC

Performing maintenance on HVAC units is essential to ensure their efficient operation, longevity, and safety. By committing to a maintenance schedule and having your equipment coated with CoilSafe or CoilSafe Plus, you can enjoy a longer life cycle for your HVAC equipment. That’s an increase in both savings and energy efficiency.

To help you get started maintaining your existing equipment, our team has outlined the main aspects you and your facility team should focus on. While the specific steps may vary depending on the type of HVAC system you have, here's a general guide to performing maintenance:


Note: It's important to follow manufacturer guidelines and consult professionals if you're unfamiliar with HVAC systems or your unit requires specialized maintenance.


  1. Regular Inspections:

  • Schedule routine inspections by a qualified HVAC technician. Ideally, have the unit inspected before each heating and cooling season starts.

  • Regularly check for visible damage, wear, or corrosion on the unit, pipes, and connections.

  1. Air Filters:

  • Replace or clean air filters regularly, usually every 1 to 3 months or as the manufacturer recommends.

  • Dirty filters can restrict airflow, decrease efficiency, and lead to poor indoor air quality.

  1. Cleaning:

  • Keep the area around the outdoor condenser unit clear of debris, plants, and obstructions to ensure proper airflow.

  • Clean the condenser and evaporator coils annually. Dirty coils reduce efficiency and can lead to cooling problems.

  1. Condensate Drain:

  • Check and clear the condensate drain to prevent clogs and water damage. This should be done annually.

  1. Thermostat Check:

  • Ensure the thermostat is calibrated and functioning correctly. Replace batteries if necessary.

  • Verify that the thermostat settings correspond to your comfort needs and the season.

  1. Electrical Components:

  • Inspect electrical connections, wiring, and terminals for signs of damage or overheating.

  • Tighten any loose connections to prevent electrical issues.

  1. Refrigerant Levels:

  • HVAC units that use refrigerant need proper refrigerant levels for efficient operation.

  • Low refrigerant levels could indicate a leak, which a professional should address.

  1. Ductwork Inspection:

  • If your HVAC system uses ducts, inspect them for leaks, damage, or mold growth.

  • Properly sealed and insulated ducts ensure efficient airflow and temperature distribution.

  1. Fan and Blower Maintenance:

  • Check and clean the blower assembly and fan components.

  • Lubricate motor bearings if applicable (consult manufacturer guidelines).

  1. Safety Checks:

  • Test safety controls, including limit and pressure switches, to ensure they function properly.

  1. Professional Maintenance:

  • While you can do many maintenance tasks yourself, having a professional HVAC technician perform a thorough inspection and maintenance at least once a year is recommended.

  1. Documentation:

  • Keep records of all maintenance performed, including dates and any repairs or parts replaced. This can help you track the system's performance over time.


Remember that HVAC systems can be complex, and if you're not comfortable or experienced with maintenance tasks, it's best to consult a professional technician (if you don’t have one on your facility team) to ensure the safety and efficiency of your unit.
