Why clean indoor coils, they have a filter for that
Dirt and debris on air-conditioning coils is a serious maintenance problem, especially in a home like ours with five dogs. Dirty coils reduce airflow, decrease efficiency, reduce HVAC capacity, and are a major cause of compressor failure and sick building syndrome.
Indoor coils are located in the air handler and they have filters. Ours is in the hall closet. Filtering is important because indoor coils are located in tight spaces and in many cases draw air from near the floor where most pollutants exist.
Filters should be changed whenever they become dirty. Pressure gauges, filter indicator lights, and filter alarms alert homeowners to ensure timely filter replacement.
Indoor coils also have drain pans that require careful cleaning to prevent their accumulated debris from becoming airborne and polluting the building’s air. It requires care to contain the mess created by coil cleaning, but containment and careful cleanup is important to protect indoor air quality
