Answer: The answer is simple this; remember to change the heating and air conditioning air filter. Changing furnace and return air filters is critical to the proper performance of your HVAC system. There is no set answer to this question. A small house with four kids, three dogs, and a cat, will need more frequent filter changes up to once a week. A large house with one person and no pets could go up to six months without needing a filter change. The only way to be sure is to replace your old filter with a new one and check it once a week until the filter is noticeably dirty.
