For the typical homeowner, changing air conditioner filters is one of the easiest HVAC system maintenance tasks you can perform. And, it’s an important facet of routine heating and cooling system maintenance because a clean filter can help keep your system running efficiently and reliably for years.
As a part of your heating and air conditioning system, the air filter plays two main roles:
- Removal of airborne particles from the air that you breathe to improve indoor air quality
- Keeping internal components free from dust and debris to maintain efficiency and reliability of operation
A dirty filter can cause a number of issues with your system. It can restrict air flow, which not only affects your comfort, but can lead to your system’s air handler working harder than normal. Over time, that can cause unnecessary wear and tear on system components. In more extreme cases a clogged filter can lead to the system turning on and off many times in rapid succession (short cycling) or even shut down completely.
To avoid these issues, be sure to inspect, clean or replace your AC filter regularly as a part of your air conditioner maintenance routine. If you do, you can help keep your system running smoothly and efficiently, and hopefully avoid an unnecessary service call from your local HVAC technician. And, once it becomes a habit, you’ll find that changing an air conditioner filter is an easy, low-cost way to maintain your comfort and hopefully save a little money down the road.
