When your furnace is running like it should, it should give warmth without making too much noise. While it’s common to notice your furnace making noise as it turns on, other sounds are signaling your furnace needs immediate professional help.
Here are some of the most frequent furnace noises and what they could be indicating. If your furnace is making an atypical noise, our friendly heating professionals are here to help with the best furnace repair in Florissant, Missouri.
1. Furnace Making a Banging Noise
You may have a critical issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be several problems. These range from gas increasing in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system becomes filthy as time passes, so that’s why it’s important to schedule annual furnace maintenance with B & B Heating & Cooling. One of the tasks our professionals perform during this service is clean your furnace’s burners. When this part gets grimy, you may hear your furnace making a loud rumbling noise after ignition takes more time. The resulting gas buildup may break your furnace’s heat exchanger, where natural gas changes into warmth. Any breaks in it can leak carbon monoxide, which is regularly emitted away from your home. This dangerous gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, B & B Heating & Cooling advises turning it off and calling us at 314-325-7552. Significant natural gas in your furnace or a cracked heat exchanger are critical issues that require immediate repairs.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide heated air around your residence. If the ductwork wasn’t designed correctly or is aging, it can be loud when your furnace runs. This may be the case if your furnace makes a banging noise when it shuts off. Get in touch with B & B Heating & Cooling at 314-325-7552 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 often is telling you there’s 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 might hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends hot or cooled air around your residence, and a capacitor, which turns on the motor. If either of these pieces are fading, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be related to something minor, like an unsecure screw, or something critical, like a broken part. In either case, we advise shutting your furnace off and getting in touch with our heating professionals at 314-325-7552 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to tell you it could use some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing could need to be greased. We are aware that maintenance often slips your mind, but our pros 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 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 isn’t secure. If you’ve looked at your vents but are still sensing noise, B & B Heating & Cooling can assist you. It’s essential to get loose ductwork taken care of without delay, as it can make comfort troubles in your home and inflate your heating expenses.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal sound usually means there’s a problem with your furnace’s blower. Turn off your furnace off right away and contact us at 314-325-7552 for assistance.
