Skip to content Regular filter replacement helps your heating and cooling system operate at peak levels and improves indoor air quality. It is important to change filters regularly to ensure proper air flow and to keep your home free from dust, allergens and germs. Depending upon the type of filter you have, you may require monthly or less frequent (3-6 month) media filter changes. If you are unsure of what type of filter your system uses, contact your service technician.
