When your furnace is running like it should, it should provide warmth without generating too much sound. While it’s normal to hear your furnace making noise as it starts up, other sounds are indicating your furnace should get immediate professional assistance.

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

1. Furnace Making a Banging Noise

You may have a serious situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be a few problems. These include gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy as time passes, so that’s why it’s critical to set routine furnace maintenance with Select Comfort Systems. One of the things our pros do during this work is clean your furnace’s burners. When this component gets grimy, you could hear your furnace making a loud rumbling noise after ignition takes longer than normal. The ensuing gas buildup may break your furnace’s heat exchanger, where natural gas transforms into heat. Any fractures in it can leak carbon monoxide, which is regularly released outside. This toxic gas can be lethal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Select Comfort Systems advises turning it off and reaching us at 801-305-4777. Too much natural gas in your furnace or a broken heat exchanger are serious problems that should get fast service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move warm air throughout your house. If the ductwork wasn’t installed right or is getting dated, it can be loud when your furnace runs. This might be the issue if your furnace makes a banging noise when it shuts off. Call Select Comfort Systems at 801-305-4777 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace depends on an internal transformer to operate on the correct voltage. If wires or the box needs to be tightened, you might notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes hot or chilly air around your rooms, and a capacitor, which starts the motor. If either of these parts are fading, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be due to something small, like an unsecure screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at 801-305-4777 for support.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to tell you it requires some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn down or a bearing could need to be greased. We know that maintenance frequently slips your mind, but our professionals can get your furnace operating quietly again rapidly.

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You might also hear whistling while the furnace is on if a floor vent isn’t tight. If you’ve examined your vents but are still sensing noise, Select Comfort Systems can help. It’s critical to get loose ductwork taken care of without delay, as it can make comfort issues in your residence and increase your utility expenses.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal sound often means there’s an issue with your furnace’s blower. Turn off your furnace off promptly and contact us at 801-305-4777 for support.
