When your furnace is working properly, it should deliver warmth without generating too much sound. While it’s normal to catch your furnace making noise as it begins running, other noises are indicating your furnace needs immediate professional support.

Here are some of the most reported furnace noises and what they can mean. If your furnace is making an atypical noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Elk River, Minnesota.

1. Furnace Making a Banging Noise

You might have a serious situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be several problems. These range from gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy as time passes, so that’s why it’s important to set yearly furnace maintenance with Home Comfort Heating & Air. One of the things our pros perform during this work is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise if ignition takes longer than normal. The resulting gas buildup may break your furnace’s heat exchanger, where natural gas turns into warm air. Any breaks in it can leak carbon monoxide, which is ordinarily emitted outside. This hazardous gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Home Comfort Heating & Air advises turning it off and contacting us at 763-276-0617. Too much natural gas in your furnace or a fractured heat exchanger are dangerous troubles that necessitate immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver heated air across your residence. If the ductwork wasn’t designed properly or is aging, it can be loud when your furnace is heating. This may be the problem if your furnace makes a banging noise when it shuts off. Call Home Comfort Heating & Air at 763-276-0617 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace depends on an internal transformer to work on the right voltage. If wires or the box needs to be tightened, you could notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends hot or cold air around your house, and a capacitor, which turns on the motor. If either of these pieces are going out, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be the result of something small, like a loose screw, or something serious, like a broken piece. In either case, we advise shutting your furnace off and calling our heating specialists at 763-276-0617 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to alert you it needs some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing could need to be greased. We are aware that maintenance frequently slips your mind, but our technicians can get your furnace heating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You could also be aware of whistling while the furnace is on if a floor vent isn’t secure. If you’ve examined your vents but are still hearing whistling, Home Comfort Heating & Air can provide support. It’s critical to get loose ductwork taken care of without delay, since it can create comfort issues in your residence and drive up your heating expenses.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal racket often means there’s a problem with your furnace’s blower. Switch off your furnace off right away and contact our professionals at 763-276-0617 for support.
