1. Change your furnace filter
It’s recommended that you change filters at least every three months. The life of a filter can depend on the individual conditions in your home. If your home has construction or renovation work in progress, furniture or drywall sanding in progress, pets, smokers, or a fan running continuously, you may want to change the filter more often. Changing the filter before each seasonal change is a great way to maintain the air quality in your home but also keeps your HVAC system running like it should. If you have an older furnace, you may notice that it runs better with a fresh filter and may need a filter change more often depending on how often it’s being used.
