When your furnace is running like it should, it should give warmth without generating too much sound. While it’s common to catch your furnace making noise as it begins running, other disruptions are signaling your furnace should get immediate professional support.

Here are some of the most reported furnace noises and what they might mean. If your furnace is making a weird noise, our friendly heating pros are here to help with the best furnace repair in Brookfield, Connecticut.

1. Furnace Making a Banging Noise

You could have a critical situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be a couple of problems. These involve gas increasing in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy over the years, so that’s why it’s essential to set seasonal furnace maintenance with Central Air LLC. One of the tasks our pros do during this appointment is clean your furnace’s burners. When this component gets dirty, you could hear your furnace making a loud rumbling noise when ignition takes longer than normal. The following gas buildup might fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any fractures in it can emit carbon monoxide, which is regularly released outdoors. This hazardous gas can be deadly in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Central Air LLC advises turning it off and calling us at 203-357-5913. Too much natural gas in your furnace or a fractured heat exchanger are critical troubles that require immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver hot air across your home. If the ductwork wasn’t designed properly or is aging, it can be noisy when your furnace is heating. This may be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Central Air LLC at 203-357-5913 and we’ll figure out the problem.

2. Furnace Makes a Buzzing Sound

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

Your furnace depends on an internal transformer to operate on the right voltage. If wires or the box isn’t tight enough, you may detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends warm or chilly air across your rooms, and a capacitor, which triggers 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 can be the result of something minor, like a loose screw, or something major, like a broken piece. In either case, we urge you to shut your furnace off and contacting our heating pros at 203-357-5913 for support.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to alert you it requires some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be lubricated. We are aware that maintenance frequently slips your mind, but our technicians can get your furnace operating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You might also notice whistling while the furnace is on if a floor vent isn’t secure. If you’ve examined your vents but are still hearing noise, Central Air LLC can help. It’s essential to get loose ductwork taken care of without delay, because it can create comfort problems in your house and increase your heating expenses.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal racket frequently means there’s a problem with your furnace’s blower. Shut down your furnace off right away and reach us at 203-357-5913 for assistance.
