The air conditioner that keeps your household comfortably cool through the late spring and summer contains an air filter designed to keep debris from entering the AC’s cabinet through the return ducts. As part of regular maintenance to see that your air conditioner operates its best—and keeps operating its best for many years—you need to change this filter for a new once a month during the cooling season. (If your AC has a permanent filter, take it out once a month and clean it using a garden hose on low pressure.) If you don’t know where the filter is our how to change it, ask your air conditioning technician during annual professional maintenance session to show you.
Why this job is important
A clogged air filter is one of the leading causes of problems with an AC’s performance. Almost all of these problems are avoidable with monthly filter changing/cleaning. Here are some of the issues that a clogged filter can cause:
- Reduced energy efficiency – If the airflow into the air conditioner’s cabinet is choked off at the filter, the system will drain more electricity in order to run. This will cause a rise—often a steep rise—in utility bills.
- Ice along the coils – If insufficient warm air blows across the coils inside the air conditioner cabinet, the coils will remain too cool and water vapor will start to freeze along them. Frozen coils rapidly lose their ability to draw heat from the air, leading to an air conditioner that doesn’t provide cooling.
- Motor damage – The filter’s ability to stop debris from entering the cabinet will drop if it is clogged, and dust and dirt will start to get inside and coat important mechanical components, such as the motors. The extra stress on the air handler motor can cause it to burn out and need replacement.
Keep in mind that replacing the filter is only one step in maintaining an air conditioner. The other steps need the assistance of professional HVAC technicians during a spring maintenance visit.
