Your furnace unit ideally creates a soft humming sound during operation. But if you heard strange and distracting noises that are new to you, then your system is in great trouble. These sounds send a signal that you need to call your local HVAC company for expert inspection and repair.
Here are the five (5) strange furnace sounds and their meanings:
Grinding sound is caused by a loose wheel. While tightening it may solve the issue, in most cases, it requires replacement. This sound also occurs if your motor mount needs a repair. Be sure to call your technician to find the root of the problem and perform a repair.
The rattling sound commonly occurs when something is stuck in the air filter. As the air blows, the object flaps in the wind and hits the side of your unit, which creates a rattling noise. You are lucky if this is the case since you only need to clean your air filter and position it back to its place. But if you already did this and still hear the rattling sound, then it is time to call the professionals as it indicates a more serious issue.
You can blame this problem to the combustion fuels and by-products of natural gas that gather inside your unit. They can create a partial blockage to your burner assembly and make a booming sound as your furnace operates. So make sure to call your local technician to clear them out in your unit.
The squealing sound is caused by the accumulated dust and dirt in the air filter. The tiny space left for the air to escape causes a whistling sound as your unit operates. Sometimes, this noise is created by the friction of your unit’s moving parts that work close to each other. This happens due to lack of lubrication, so call a technician to inspect the parts and apply some lubricant solution to them.
A thumping sound is heard if your blower wheel loses its balance. This problem is serious and you need to report it at the moment you hear it. Call your technician immediately to address your unit’s problem and get your comfort back once again.
