The Importance of Changing Your Air Filter

Published by Steven Weiland

As your Chicago HVAC contractor, Heatmasters wants to ensure that you are taking every step to keep your system running smoothly. By changing your air filter once a month, you can extend the lifespan of your system as well as keep the individuals in your home healthy.

Extending the life of your HVAC

The most common reason that a HVAC system breaks down is because of a dirty air filter. As the filter collects more dirt, air cannot pass through and could cause the system to overheat. If you have an older unit and do not replace the filter, it will cause the system to break prematurely.


If your air filter becomes so dirty that it starts clogging the system, it will cause the system to go into overdrive and use more energy. When it requires more energy to make your HVAC system work, it will cause your energy bill to dramatically increase.

Indoor Air Quality

Air quality is rating the air that you are breathing in, and if you have a dirty air filter, it will negatively impact your homes indoor air quality. Continually breathing in air that passes through a dirty filter will affect your health and well-being. You and your family might begin to develop coughs or runny noses because of a dirty air filter.


Unfortunately, a dirty air filter can also lead to mold and mildew. When the filter comes into contact with water, it is likely to become a breeding ground for mold and mildew. This is a serious health risk for those who are living in the home.

Changing your air filter is an easy, yet necessary way to extend the life of your HVAC as well as keeping the air you breathe clean. Contact Heatmasters, your Chicago HVAC contractor, for more information.
