Why Does My Furnace Make Loud Noises? – The Common Causes of Furnace Noise

Are loud furnace noises keeping you from getting a good night’s sleep? If so, it’s time for an inspection from Dunn Heating ClimateCare to have us identify the exact source of the problem. Ignoring furnace noises could lead to damaged parts and the possibility of a new furnace purchase. Catching the problem in time often means simple maintenance and cleaning will fix it. 
If banging noises happen when your furnace turns on, it may be caused by dirty burners. This delays ignition; gas builds up before the burners ignite. You’re hearing a small explosion of excess gas. If that sounds a little scary, it is. Ignoring this problem can lead to a cracked heat exchanger or worse. Once the heat exchanger goes, you’ll be buying a new furnace.

If banging noises happen away from the furnace, you may be hearing expanding and contracting air ducts. Different parts of the air ducts pop in or out as air is blown and sucked through them. Though this problem is less serious, it still needs attention. Your air filter may be so clogged that it is not working correctly or the ducts may be undersized for the system. Sometimes, closed vents cause expansion and contraction. Whatever it is, your system is not operating efficiently, and that costs you money.
