What Causes Furnace Noises in my Carlisle Home?

An unexpected noise from a furnace can startle even the most confident of home owners. A furnace noise can indicate a very serious problem, or it may simply be an indicator of a problem that’s just beginning. The good news is that if you live in Carlisle PA, help for your furnace problems is only a phone call away. Recently we received a call from a concerned customer who explained that their furnace was making loud banging and popping noises every time it turned on. After paying a visit to the home, one of our technicians discovered that dirt was clogging the burners and delayed the burners from lighting, so the gas would build up and ignite. This was the cause of the banging and popping noise. A simple annual cleaning is the solution. Another happy customer.

Elizabethtown Furnace Installation and RepairSeveral symptoms and causes of furnace noise.

Metal scraping on metal
Not only is this one of the most annoying sounds from a furnace, it’s also one of the most serious. If you hear a noise that sounds like metal scraping across metal, shut down your furnace and call us. This sound usually indicates a problem with the blower wheel. Whether the blower wheel is broken, or is hitting the housing or has completely dropped, this noise should be investigated immediately.

Banging and popping
If a banging or popping noise occurs when the furnace is first turned on, it usually indicates dirty furnace burners or metal air ducts that are expanding or contracting. The bangs are created by small explosions from the dirty burners. These explosions can crack the heat exchanger, so don’t ignore this sound either.
