As the seasons change, many homeowners ask us a crucial question about their cooling system. At Alpha Comfort Systems, we know that understanding how often to change your AC filter is fundamental to your home's comfort and your system's health. It’s a simple task that pays huge dividends in efficiency and air quality.
How often should I change my AC filter?

The General Rule of Thumb
For the average suburban home without pets, we recommend replacing your filter every 90 days. This baseline is a great starting point for most households. Sticking to this schedule helps prevent the buildup of dust and debris that can strain your AC unit and increase your energy bills over time.

Homes with Pets
If you share your home with furry family members, pet dander can clog your filter much faster. For households with one or more pets, we advise you to change your AC filter every 60 days. This increased frequency is key to maintaining healthy indoor air quality and keeping your system running smoothly.

Allergy Sufferers and Families with Children
For individuals with allergies or families with young children, clean air is a top priority. In these cases, it's best to change your AC filter every 30 to 45 days. This proactive step helps to significantly reduce airborne irritants like pollen and dust mites, creating a more comfortable and healthier living space.

Vacation Homes and Seldom-Used Spaces
If you have a vacation home or a room that is rarely used, you don’t need to replace the filter as often. We suggest checking it every 6 to 12 months. While usage is low, dust can still settle, so an occasional check-up ensures the system is ready for when you need it.
Ultimately, a clean filter is essential for an efficient air conditioning system. Regular changes protect your unit, improve your air quality, and can even lower your energy costs.
