Why should I change my air filter?

When was the last time you changed your AC filter?

If you always let the technician handle the job during annual tune-ups, your filter is not being replaced often enough. It’s great to know the importance of changing the air filter, but locating the slot/track for your filter can be a little tricky. The location of your air filter depends on type of AC unit in your house. Here are the most common places to look:

If you have postponed changing the air filter in your unit more than once, you probably do not realize how important it is and why. There are a lot of benefits that come from changing your air filter. Here is a list of just a few:

  • Prevent early system failure: A dirty filter restricts airflow and makes the air handler work harder than necessary. Over time, the fan motor could burn out, causing the system to overheat and ultimately fail. A new filter protects the system and helps it run years longer.
  • Save energy: A system overworked by blocked airflow consumes more energy. Reduce your home’s energy consumption by changing the filter regularly.
  • Lower utility bills: Greater energy consumption causes higher energy bills. The cost of replacing the AC filter partially pays for itself with lower cooling bills.
  • Improve air quality: In addition to protecting the AC unit from large dust particles, a filter also traps pollutants that circulate through the system. This leaves you with cleaner indoor air so you can breathe easier.

Now that you know why it is necessary to change your air filter, it’s time to choose the right filter replacement. Choosing a higher efficiency filter helps clean the air better and prevents small particles from landing on sensitive air conditioning equipment.
