You'd be amazed how many HVAC problems are caused by someone
forgetting to change their air filter. At the same time, giving advice on this is hard without knowing your individual home/situation. This answer can be different depending on a lot of variables like, how many people live in the home? Is your home near construction? Do you have pets in the home? All of these, and more, can play in to how often your filter should be changed. Our standard answer to this question is, if you use a 1-inch disposable filter, replace it monthly. Even most 90-day filters do not last a true 90 days so we suggest changing those out every two months. If you would like a personalized
air quality recommendation, just ask our HVAC technician on your next maintenance visit.
