If You Have a Forced Air Furnace, You Need to Check the Air Filter

Posted: October 26, 2017

With proper maintenance, the average HVAC* system can last 12-15 years. One way to make sure your system reaches its life span and operates efficiently is to perform an easy, do-it-yourself maintenance task. This means changing or cleaning your furnace’s air filter as often as the manufacturer recommends. In general, you should check the filter’s condition once a month and change/clean it when necessary.

4 quick points

  1. Filters are located either inside the furnace or inside the return air vent.
  2. Some filter models are designed to be discarded and replaced with a new one.
  3. If your filter has a plastic frame, it can be cleaned and reused.
  4. Always follow manufacturer’s instructions and be sure to shut the furnace off before handling the filter.
