You’re sitting in your house during a winter night, enjoying warmth coming from the furnace attached to the ductwork. Then suddenly, you hear the furnace make a noise different from the usual hum you hear from its blower fan. It could be a clang, a boom, a click, or a disquieting shrieking. Is something wrong?
Possibly. Just like a house settling, sometimes a furnace may make a slightly different noise, but it doesn’t return. But if the noise is persistent or causes the furnace to make a racket, there probably is a repair issue with it that will require heating repair in Salt Lake City, UT from professionals.
