Why Is My Furnace Making Strange Sounds?
Most mechanical devices, such as your furnace, and some electric appliances make noise when operating. So how can you discern between normal furnace sounds and what should be taken seriously as a warning sign?
Typically, the sound of normal operation will be a low hum or a similar soft sound. If you hear clanging, banging, loud clicking or other unusual furnace noises, a professional heating company like Brackett Heating & Air has experienced technicians to check your furnace. If a part is broken or worn, a furnace repair can be completed quickly and efficiently to ensure your home stays cozy and warm.
Sources of Furnace Noises
- If you hear scraping sounds or metal hitting against metal, this could signify a problem with your blower wheel, which may be loose or need to be replaced. The worst action to take is ignoring the noise. Instead, turn off the furnace and call Brackett.
- Screeching may mean the bearings in the blower motor need lubricated or perhaps a belt needs replaced. Brackett Heating & Air can handle any other furnace repair.
- While some popping noises are normal due to ductwork expanding and contracting, frequent or unusually loud banging sounds shouldn’t be brushed aside. Have a professional technician investigate to be sure there isn’t an underlying, larger problem.
- Rattling noises could be as simple as a loose access door or panel, or it might mean a loose interior part. If after checking the doors and panels you still hear the noise, call Brackett Heating & Air for a full inspection to catch any malfunctioning components inside your furnace.
There could be other reasons for a noisy furnace such as clicking, rumbling or exceptionally loud humming or buzzing to name a few. A good rule of thumb is that if your furnace begins making noises you’ve never heard before and they’re unusually loud, engage the services of a trained HVAC professional. It’s better to err on the side of caution.
