Check & Replace HVAC Filters

I've read various reports as well as had a ton of feedback from HVAC specialists on frequency here but the common answer is... it depends. If you have a couple of pets, kids, and you're sensitive to allergens? Maybe 2-3 weeks. No pets and not sensitive? 60 days. Best bet is to check every 30 days.

Replacing the filters not only improves the efficiency of your home but can make a noticeable difference in your air quality. But don't forget the return air vent filter which I certainly have done. Your return air vent is most likely the only vent in your home that a filter is visible. They can be located on the ceiling and near the floor.
