When your furnace is operating properly, it should provide warmth without making too much noise. While it’s common to notice your furnace making noise as it turns on, other noises are indicating your furnace requires immediate professional assistance.

Here are some of the most common furnace noises and what they might be signaling. If your furnace is making an atypical noise, our friendly heating professionals are here to help with the best furnace repair in Newton, Iowa.

1. Furnace Making a Banging Noise

You may have a serious situation on your hands if you’re detecting 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 increasing in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty as time passes, so that’s why it’s important to book seasonal furnace maintenance with Brookwood Inc. One of the jobs our techs perform during this service is clean your furnace’s burners. When this piece gets grimy, you may hear your furnace making a loud rumbling noise if ignition takes longer than normal. The following gas buildup can fracture your furnace’s heat exchanger, where natural gas transforms into warmth. Any breaks in it can leak carbon monoxide, which is normally vented outdoors. This toxic gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Brookwood Inc urges you to turn it off and contacting us at 641-316-9803. Significant natural gas in your furnace or a fractured heat exchanger are dangerous issues that necessitate immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver hot air across your residence. If the ductwork wasn’t installed properly or is aging, it can be loud when your furnace is on. This could be the problem if your furnace makes a banging noise when it shuts off. Call Brookwood Inc at 641-316-9803 and we’ll determine the problem.

2. Furnace Makes a Buzzing Sound

If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound frequently means there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to work on the right 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 has a blower motor, which distributes heated or chilly air throughout your house, and a capacitor, which turns on the motor. If either of these components are failing, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be due to something little, like an unsecure screw, or something major, like a broken component. In either case, we advise shutting your furnace off and contacting our heating specialists at 641-316-9803 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to alert you it requires some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be greased. We realize that maintenance often slips your mind, but our professionals can get your furnace heating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re detecting your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You might also be aware of whistling while the furnace is on if a floor vent isn’t tight. If you’ve checked your vents but are still noticing noise, Brookwood Inc can help. It’s important to get loose ductwork taken care of fast, because it can result in comfort problems in your home and drive up your heating expenses.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal racket usually means there’s a problem with your furnace’s blower. Switch off your furnace off promptly and call our pros at 641-316-9803 for support.
