When your furnace is working properly, it should provide heat without generating too much noise. While it’s expected to notice your furnace making noise as it begins running, other sounds are showing your furnace should get immediate professional help.

Here are some of the most frequent furnace noises and what they might mean. If your furnace is making a weird noise, our friendly heating specialists are here to assist with the best furnace repair in West Valley City, Utah.

1. Furnace Making a Banging Noise

You might have an urgent problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be several problems. These include gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy as time passes, so that’s why it’s essential to schedule routine furnace maintenance with Select Comfort Systems. One of the jobs our pros do during this work is clean your furnace’s burners. When this part gets dirty, you may hear your furnace making a loud rumbling noise after ignition is delayed. The resulting gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can emit carbon monoxide, which is ordinarily released outside. This toxic gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Select Comfort Systems urges you to turn it off and reaching us at 801-305-4777. Significant natural gas in your furnace or a fractured heat exchanger are hazardous issues that require fast service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver warm air throughout your house. If the ductwork wasn’t installed correctly or is getting old, it can make a lot of noise when your furnace runs. This can be the case if your furnace makes a banging noise when it shuts off. Call Select Comfort Systems at 801-305-4777 and we’ll figure out the problem.

2. Furnace Makes a Buzzing Sound

If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run on the proper voltage. If wires or the box needs to be tightened, you could hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends heated or chilly air across your space, and a capacitor, which turns on the motor. If either of these components are fading, they will buzz when the furnace turns on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it can be related to something little, like an unfastened screw, or something critical, like a broken part. In either case, we recommend shutting off your furnace and contacting our heating pros at 801-305-4777 for assistance.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to alert you it requires some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be lubed. We realize that maintenance sometimes slips your mind, but our technicians can get your furnace running quietly again quickly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re detecting your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You could also hear whistling while the furnace is on if a floor vent isn’t secure. If you’ve examined your vents but are still noticing whistling, Select Comfort Systems can assist you. It’s essential to get loose ductwork repaired fast, as it can create comfort problems in your home and drive up your gas bills.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal noise usually means there’s an issue with your furnace’s blower. Turn off your furnace off now and reach our professionals at 801-305-4777 for support.

When you’re getting an atypical noise from your furnace, Select Comfort Systems is available to provide assistance. Contact us at 801-305-4777 to schedule your furnace repair appointment now.
