If You Haven’t Replaced Your Furnace Filter In A While, You’re Wasting Money
Changing your filter when needed is a necessity: it makes your furnace run more efficiently and prolongs its lifespan. If you want to save money in the long run, replace your filter. During high-usage periods of the winter, replace your filter once a month. Freestanding or wall unit air conditioners only need to be replaced yearly, but they still need to be cleaned every month. Following these steps will keep your electric bill down significantly.
