Changing Your HVAC Air Filter

What is the most important thing you can do to keep your HVAC unit performing well between check-ups? Change your air filter. This is critical to the proper performance of your HVAC system. Changing your filter also drastically increases the air quality in your home. Since indoor air pollution is one of the most common environmental health risks, it is important to know when to change your air filters. Depending on the type of filter you have, determines when you need to change your filter. Some filters need to be changed as often as every thirty days while some can go as long as six months. Several factors contribute to needing to change filters more often such as pets in the home, number of occupants in the home, and number of occupants with allergies. For homes with a single occupant and no pets or allergies, the filter can be changed every six to twelve months. The average home without pets should be changed every ninety days. Homes with pets can be changed every sixty days while homes with pets and allergies should be changed monthly. Spencer Air Conditioning and Heating invites you to call us for all of your HVAC needs.
