The integrity of your furnace or air conditioner depends on how well it’s maintained. If your furnace or air conditioner are more than 5 years old, it is a good idea to have them serviced once per year. And don’t forget to change or clean that filter at least once per year no matter what the age of your furnace or air conditioner.
