Posted on: Feb 23, 2017

Spring is just around the corner! And that means you want to pull out your checklist for maintenance of your commercial HVAC systems. A regular schedule ensures your heating, ventilation and air conditioning units will perform their best. Furthermore, proper maintenance adds years to the life of your units.

During the maintenance routine, you should look for potential problems. In so doing, you are able to prevent the majority of issues associated with HVAC systems. To avoid leaving your employees and customers without air conditioning this summer, now is the time to check your units.

Spring Cleaning Routine


The most common reason for commercial HVAC systems to fail is a clogged filter. And changing the filter is the easiest maintenance chore to perform. To ensure the changing schedule stays up-to-date, keep a stack of filters in the closet, so they are always available when needed.

Condenser Unit

Check around the outside unit for debris and leaves. Nothing should be within several feet, so air may flow freely. If any coils are bent, gently straighten them.  Clean with soapy water and rinse.


Check all the wires for any damage from mice or other rodents. Look for loose connections and any scorched wiring.

Refrigerant Levels

See if any refrigerant has leaked and change hoses that show wear. If the level is low, top it off.

Drain Lines

Mineral deposits may build up. Check for any blockage. A common problem is mold, which also may block the flow. Be sure you have proper drainage.

Blower Fan

A common issue here is dust, dirt and other debris. Remove it from the surface so airflow is optimal.

Evaporator Coils

The best way to keep the coils clean is to replace the air filter regularly. For commercial HVAC systems, it should be every month. When the coils are clogged, use soapy water to remove the debris.

Preventative maintenance saves you money. The units will run more smoothly. They will heat and cool more effectively, and require less energy to do so.
