A noisy furnace can ruin a cozy night in fast! Not only are the sounds annoying, but they can also indicate underlying issues that shouldn’t go unnoticed.

Thankfully, there are techniques you can use to stop the noises and bring peace and quiet back into your home.

Follow along as we discuss how to quiet a noisy furnace.

Replace Filters

If you notice banging noises coming from your furnace, then airflow issues may be the culprit. As soon as you hear the sounds, check your unit for dirty or damaged filters. If you find that they’re worn out, remove and replace them immediately.

Dirty filters make it impossible for air to flow freely through the furnace which then causes loud noises and puts you and your family at risk for carbon monoxide poisoning.

Lubricate

The insides of furnaces contain several moving parts to help them function properly. These parts include blower wheels. When they’re disrupted, it causes the furnace to make a squealing noise.

When this occurs, all you need to use is lubrication oil to help loosen up the wheels. Since it can get backed up over time, regular maintenance is needed to ensure that it stays in good condition. It’s recommended to oil the wheels once a year to prevent damage.

Secure Access Panels

Furnace issues can also manifest themselves as rattling noises. These sounds, however, could be as simple as a loose screw or as serious as a loose panel.

If you’re experiencing rattling, turn off your furnace immediately and make sure all screws and panels are secure. This should solve the problem and get your system up and running as normal.

Open Supply Vents

High pitched sounds are an indication of low return airflow. It’s best to open your vents when you notice the noise. The root of the problem could be caused by increased pressure being put on the ductwork as a result of closed vents.

Once you do open vents, it may also be best to get ductwork cleaning done to fix the issue as well.

Call a Professional

There are several things you can do on your own to quiet your furnace but some problems could be a health risk. If you’ve tried all of the techniques mentioned with no success, then professional assistance is needed.

Your furnace may be experiencing major issues such as metal rubbing against each other or worn bearings. In this case, it’s best to have an expert come in and inspect.
