Various Furnace Noises and What Causes Them.

Winter is here with a vengeance after the mild weather we had most of the season. Now that it is cold outside we have all started turning on our furnaces. For most, turning on the furnace was a smooth process with no issues but what if your furnace is making a loud noise? Noise is definitely not normal and there could be a few different reasons for noise. We will go over a couple of those reasons below. A loud bang at start up could be a delayed ignition. This happens when unburned oil builds up in the fire box chamber and is ignited all at once. This could be dangerous so make sure you call a technician at Bartlett Heating and Air right away. If your furnace makes noises while running you could have an issue with the fan that blows the hot air. If your furnace makes noises while running you could have fan bearings that are worn and need replacing. If your furnace makes noises while running you could have issues with any of the fans inside the furnace, this is usually a screeching sound. If you have a metallic chirping noise it might just be a natural noise. You can fix this by trying to align the wheel and also check that the mounting plate isn’t warped and rubbing against the blower. If there is a noisy rattling when your furnace shuts off, it very well may be the parts cooling down and nothing to worry about. Clanging noises are often the pipes contracting and cooling down. A loud bang could also mean a dirty burner or could also be the duct work contracting and expanding. A loud bang could also possibly be a dirty or broken gas valve. Odd vibrating or whining sound could be the furnace and that needs to be check out by a technician. A clunking or bumping sound could be a cracked belt. Some noises your furnace make are annoying but not harmful and others are dangerous so it is always best to call a qualified technician like the ones at Bartlett Heating and Air to come check and make sure the furnace is running safe or fix any issue you might have.
