When your furnace is running correctly, it should provide heat without making too much sound. While it’s common to notice your furnace making noise as it begins running, other noises are indicating your furnace requires immediate professional support.

Here are some of the most frequent furnace noises and what they could be signaling. If your furnace is making a strange noise, our friendly heating specialists are here to assist with the best furnace repair in Newton, Iowa.

1. Furnace Making a Banging Noise

You may have an urgent issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a few problems. These include gas increasing in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty over the years, so that’s why it’s essential to set routine furnace maintenance with Brookwood Inc. One of the things our techs complete during this appointment is clean your furnace’s burners. When this component gets grimy, you might hear your furnace making a loud rumbling noise if ignition is delayed. The following gas buildup may crack your furnace’s heat exchanger, where natural gas transforms into warmth. Any cracks in it can emit carbon monoxide, which is ordinarily released outdoors. This dangerous gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Brookwood Inc advises turning it off and reaching us at 641-316-9803. Significant natural gas in your furnace or a ruptured heat exchanger are critical issues that require prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses 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 runs. This might be the case if your furnace makes a banging noise when it shuts off. Contact Brookwood Inc at 641-316-9803 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound typically means there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to run on the correct voltage. If wires or the box is loose, you could detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends heated or cold air across your residence, and a capacitor, which triggers the motor. If either of these pieces are failing, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be the result of something minor, like an unsecure screw, or something major, like a broken piece. In either case, we advise shutting your furnace off and calling our heating specialists at 641-316-9803 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 requires some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing could need to be lubed. We are aware that maintenance frequently slips your mind, but our professionals can get your furnace operating quietly again quickly.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You may also notice whistling while the furnace is working if a floor vent isn’t secure. If you’ve looked at your vents but are still sensing whistling, Brookwood Inc can help. It’s essential to get loose ductwork taken care of quickly, because it can result in comfort issues in your home and drive up your energy bills.

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 frequently means there’s trouble with your furnace’s blower. Turn off your furnace off now and reach our pros at 641-316-9803 for assistance.
