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

1. Furnace Making a Banging Noise

You could have a serious problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be several problems. These include gas increasing in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy as time passes, so that’s why it’s essential to book seasonal furnace maintenance with Brookwood Inc. One of the things our techs perform during this work is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise after ignition takes longer than normal. The resulting gas buildup might crack your furnace’s heat exchanger, where natural gas changes into heat. Any cracks in it can leak carbon monoxide, which is ordinarily emitted outdoors. This dangerous gas can be lethal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Brookwood Inc urges you to turn it off and calling us at 641-316-9803. Significant natural gas in your furnace or a broken heat exchanger are hazardous problems that necessitate prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver heated air around your home. If the ductwork wasn’t installed right or is getting old, it can be noisy when your furnace is heating. This may be the case if your furnace makes a banging noise when it shuts off. Get in touch with Brookwood Inc at 641-316-9803 and we’ll figure out 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 often means there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to operate on the proper voltage. If wires or the box isn’t tight enough, you could hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or cooled air around your rooms, and a capacitor, which triggers the motor. If either of these parts 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 may be the result of something minor, like a loose screw, or something serious, like a broken component. In either case, we advise shutting your furnace off and calling our heating professionals at 641-316-9803 for help.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to tell you it could use some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing may need to be lubed. We are aware that maintenance sometimes slips your mind, but our professionals can get your furnace heating quietly again quickly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You might also be aware of whistling while the furnace is working if a floor vent is loose. If you’ve checked your vents but are still hearing sound, Brookwood Inc can assist you. It’s essential to get loose ductwork repaired without delay, as it can result in comfort issues in your residence and drive up your utility bills.

6. Furnace Makes a Loud, Unpleasant 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 a problem with your furnace’s blower. Turn off your furnace off immediately and call us at 641-316-9803 for help.
