Your Noisy Furnace: Do You Know What It’s Telling You?

Your Noisy Furnace: Do You Know What It's Telling You?

By in

Are you living with a noisy furnace? The booms, pops, rattles, clicks and squeals are probably more than simply annoying sounds. Chances are your furnace is trying to tell you something. Here’s a guide to help you know what your noisy furnace might be saying as well as fixes for each issue:

Booming Noises: The loud boom produced by your noisy furnace may be a bit disturbing, which should motivate you to take action quickly. This furnace noise is usually caused by dirty burners. Gas builds up behind debris that has collected until it finally pushes its way through with a boom. A technician can clean the burners for you and put an end to the noise.

Popping or Rattling Noises: When this noise comes from a certain room in your home, rather than the furnace itself, it’s most likely the ductwork making noise as it expands when hot air travels through it. You may be able to quiet the noise by tightening the ductwork with a metal brace. Flexible insulation around the ductwork can also help to muffle the noise. In extreme situations, you may need to have a contractor modify the space that your ductwork runs through.

Clicking Noises: If the furnace clicks before the gas ignites, there may be buildup on the flame sensor. This is what tells the furnace when the gas is lit. A professional can remove the rod-like sensor from its bracket and clean it with sand paper. If this doesn’t fix the problem, the sensor will need to be replaced.

Squealing Noises: The blower motor belt is usually the source of squealing furnace noises. This sound can occur if the belt is slipping or fraying. It may simply need to be adjusted by a technician, but if the belt is worn in one spot, it will need to be replaced.

You should never ignore your noisy furnace; more expensive repairs may be avoided if you give it the attention it’s asking for now. For an accurate diagnosis based on your specific situation, please contact Climate Control Company for your western Colorado home or business today.
