3 Weird Sounds Furnaces Make - And What To Do If You Hear Them

For many people, the sound of the furnace turning on is a welcome one — especially on a chilly day. However, if you start to hear weird noises coming from your furnace, it may be time to schedule heating services for your unit. Today, you will learn three of the most common sounds that furnaces make, plus what you can do about these unexpected noises.

1) Buzzing

One common furnace noise is a buzzing sound. If you hear this coming from your furnace, it could be an indication that there is something wrong with the blower motor. The blower motor is responsible for circulating air throughout your home, so if it's not working properly, it can cause all sorts of problems.

If you hear a buzzing noise coming from your furnace, the first thing you should do is check the air filter. If the air filter is dirty, it can cause the blower motor to work harder than it needs to, which can lead to a buzzing sound. Simply replacing the air filter can often fix this problem.

If changing the air filter doesn't solve the problem, you may need to call a heating technician to take a look at your furnace.

2) Banging or popping

Do you ever hear banging or popping noises coming from your furnace? If so, it's important to take action right away. These sounds can be an indication of a serious problem, such as a cracked heat exchanger.

The heat exchanger is a vital part of your furnace, and if it's cracked, it can leak carbon monoxide into your home. This is a very dangerous situation, so if you hear banging or popping noises coming from your furnace, you should shut off the unit immediately and call a heating technician. Do not try to fix this problem on your own, as self-repair can jeopardize your family's safety.

3) Squealing

If you hear a squealing noise coming from your furnace, it's likely that the blower belt is loose or needs to be replaced. The blower belt helps to power the blower motor, so if it's not working properly, it can cause all sorts of problems.

Fortunately, this is a relatively easy problem to fix. Simply tightening the blower belt can often solve the problem. However, if the belt is too damaged, you may need to replace it. This is a relatively simple repair that a heating technician can easily handle.

If you start hearing any of these strange noises coming from your furnace, don't ignore them! These sounds can be an indication that you need heating services from a local company. Schedule your appointment today and enjoy using your furnace again.
