Why is our gas furnace so loud?

If your gas furnace is making unusually loud noises, it is important to pinpoint the origin of the noise to solve the issue.

Noise can indicate an underlying harsh problem that may end up damaging your gas furnace, and multiple odd components can cause loud noises, each producing a odd 1.

Furnace noises are a warning sign of an impending danger that you should not ignore, although you would not even if you wanted to. If your gas furnace produces a loud rattling or screeching noise when you turn on your gas furnace, the bearings in your blower motor or your blower motor itself could be the culprit. The blower motor pushes overheated air out of your gas furnace as well as into your living space through the air duct; Your blower motor requires routine lubrication as well as usually a identifiable type of lubrication to upkeep optimal function as well as performance over time. Otherwise, your fan might seize up, causing a loud screeching or rattling noise. You may be having a loose or destructiond blower belt. If your gas furnace has a belt-driven motor, a squealing or similar noise may ensue when the belt loosens. Another reason for squealing noise can be attributed to shaft bearings as well as other moving components becoming dry, but lubricate the moving parts of your gas furnace regularly during bi-annual tune-ups to keep your gas furnace in peak performance throughout winter. If you experience a loud clanking or scraping, described as metal against metal sound, it signals a harsh problem with your gas furnace’s blower wheel… Dirty burners that need cleaning may cause a loud bang or boom, while a faulty heat exchanger with a loose panel or screw may cause rattling noises.
