Why Is My Furnace So Loud?

Why Is My Furnace So Loud?

You get back home after a long day of work and you're just glad to be out of the cold. You curl up on the couch and get ready to binge watch the latest hit show, and then you hear it. Your home is warm, but your furnace is making all sorts of loud noises.

Here at Day & Nite Plumbing and Heating, we specialize in handling these issues. There are a few things that could be causing your noisy furnace. We can check out any potential furnace issues and make sure that your home will soon be quiet as well as warm. Here's a look at some potential causes, many of which can cause expensive damage if left unchecked.

Unbalanced or Broken Blower Wheel

If you hear a thumping noise originating from your furnace, an unbalanced blower wheel could be the culprit. An HVAC technician can spot this problem quickly and get it balanced again, hopefully eliminating the noise problem. A broken blower wheel can vibrate, causing scratching and banging sounds. We'll find you the replacement parts you need.

Unbalanced Motor

If that doesn't work, the motor could be the issue. An unbalanced motor can cause the same kind of thumping noises. We'll see if that's the problem and make sure that the lifeblood of your furnace is operating properly.

Broken Motor Mount

It's not just your motor that can cause some annoying furnace noises. A broken motor mount could cause a rattling noise that you'll definitely notice. It's recommended that you turn off your furnace if this could be the issue, because a broken motor mount isn't just noisy. It can result in more expensive damage.

Loud Transformer

A humming noise in a furnace that's otherwise working well could be caused by a loud transformer. We'll look for that issue first, but there are some other potential causes including a bad capacitor or interior fan. Our furnace repair experts can figure out the exact problem and fix it before your furnace gets heavily damaged.

Undersized Duct

An undersized duct can cause your furnace to make some annoying banging noises. If your furnace is loud when it starts up, that could be a sign that your ducts are the problem.

Clogged Filter

A clogged filter can also cause banging noises. Fortunately, this is an easy fix for your local HVAC experts. We recommend changing your filter at least every season to avoid problems.

Loose Fan Belt

A loose fan belt can be another source of furnace noise. You'll know that this part is a problem if you hear a loud squealing noise. We'll tighten the blower belt and make sure that your furnace stays quiet all season long.

Burner Problems

A dirty burner can be the cause of loud thumping noises, caused when gas builds up and has nowhere to go. Other problems with your burner can result in low rumbling noises. These noises are constant, so it's often easy to notice that it's a problem. Turn off your furnace right away and contact us at (425) 775-6464. Your local furnace repair experts can fix this problem in no time.
