Commercial HVAC Maintenance and Cleaning

Every season, your commercial HVAC system should be refreshed by performing cleaning and maintenance. Regular maintenance ensures that the HVAC system operates at its peak efficiency. This leads to consistent and comfortable indoor temperatures, proper humidity control, and improved air quality. Well-maintained HVAC systems use less energy when heating or cooling a building. This translates to lower utility bills, reducing operational expenses for the commercial property owner. Preventative cleaning also extends equipment lifespan, leading to less downtime for repairs. Extending your equipment lifespan through cleaning and maintenance is especially important if supply chain issues make it difficult to replace commercial HVAC equipment that is no longer functional.

HVAC Maintenance Checklist

For peace of mind that your existing systems will continue performing, some of the cleaning tasks you might want to consider include:

  1. Coil cleaning – Cleaning evaporator and condenser coils in your HVAC units is one of the most important maintenance tasks you can do. Over time dust, dirt, pollen, and grime can build up in your coils. If not taken care of, the grime that builds up can cause overheated motors, reduced airflow and efficiency, and poor indoor air quality. Getting your coils cleaned will remove unwanted build up and help to ensure your equipment is performing optimally.
  2. Air handling unit – In addition to cleaning coils, you should make sure the other components of your air handling unit are cleaned. The fan and fan housing, dampers, air intakes, supply and return sections, interior insulation, and door gaskets and seals should be inspected and cleaned if needed.
  3. Drain pan & drain lines– Drain pans and drain lines are frequently overlooked components of HVAC systems. Mold and bacteria can accumulate in the drain pan and cause damage if they are not cleaned.
  4. Air ductsIf it has been a while since you have had your air ducts cleaned, you may want to consider having this done. Over time, debris, dust, mold, and allergens can accumulate in your air ducts and get circulated through the air in your building. Cleaning your ducts improves indoor air quality and can help your system perform more efficiently.
  5. Air filters – Your HVAC system’s air filters need to be changed on a regular basis. Dirty and clogged air filters can damage your system and harm the health of building occupants. Prevent issues with your HVAC system and improve the air quality in your facility by performing filter changes regularly.
  6. Clean up around outside units – Outdoor HVAC units should be cleared of leaves and other debris. There should not be anything within several feet of outside units to allow air to flow freely.
