Many experts say a heating system should be serviced at least once per year. Specifically, the best course of action is to service a heating system in the fall before colder weather arrives. And, you should get your air conditioner serviced in the spring before the weather heats up.
It’s especially important to hire a professional to perform repairs whenever you hear strange sounds, such as clanking, knocking or banging.
