When your furnace is operating properly, it should give warm air without generating too much noise. While it’s normal to notice your furnace making noise as it turns on, other sounds are indicating your furnace should get immediate professional support.

Here are some of the most common furnace noises and what they can be indicating. If your furnace is making a strange noise, our friendly heating professionals are here to help with the best furnace repair in West Valley City, Utah.

1. Furnace Makes a Banging Sound

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 may signal there could be a few problems. These involve gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns grimy as time passes, so that’s why it’s critical to book yearly furnace maintenance with Select Comfort Systems. One of the things our techs perform during this service is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise when ignition takes longer than normal. The following gas buildup can crack your furnace’s heat exchanger, where natural gas transforms into warmth. Any breaks in it can emit carbon monoxide, which is normally vented outdoors. This dangerous gas can be fatal 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 ruptured heat exchanger are dangerous issues that necessitate fast service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver heated air around your house. If the ductwork wasn’t installed correctly or is aging, it can be loud when your furnace is heating. This can be the problem if your furnace makes a banging noise when it shuts off. Contact Select Comfort Systems at 801-305-4777 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

If you notice 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 proper voltage. If wires or the box needs to be tightened, you may hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends hot or cooled air around your home, and a capacitor, which starts the motor. If either of these components are fading, they will buzz when the furnace starts.

3. Furnace Rattles

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

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to tell you it could use some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be greased. We know that maintenance sometimes slips your mind, but our technicians can get your furnace heating quietly again quickly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re hearing your furnace making a whistling noise, it’s typically due to 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 checked your vents but are still hearing sound, Select Comfort Systems can provide support. It’s critical to get loose ductwork taken care of without delay, as it can make comfort issues in your residence and inflate your utility costs.

6. Furnace Making a Grinding Noise

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