Changing Dirty Air Filters Increases Performance of Your Furnace

The most important thing a homeowner can do to keep their furnaces running efficiently is to check and change the air filters on a regular basis. 

The purpose of a basic furnace filter is to protect your system from dirt and debris that could affect the performance of your system. Some more advanced filters are used to stop airborne particles like dust and other unhealthy microscopic particles from being distributed into your home’s air. It’s natural that all of that material will build up on your filter over time.

When your filter gets too dirty, your furnace has to work harder. Unclean air is redirected to other parts of your unit because it is not able to pass through your filter. This can lead to unnecessary repairs due to build up and damage to different parts of your furnace.

When air is unable to easily pass through your filter, your furnace has to work extra hard to make up for the loss of air flow. As a result, your unit uses more energy and your utility bills begin to grow.

It’s very easy to avoid the consequences of a dirty air filter. Mark your calendar to check your filters on the first of every month, especially during the times of the year that you’re using your furnace the most. One simple test is to hold your filter up to a light and see if light is able to pass through. If not, it’s time to clean or change your filter, depending on the type that is installed in your unit.
