When your furnace is working properly, it should give warmth without generating too much disruption. While it’s expected to hear your furnace making noise as it starts up, other noises are signaling your furnace requires immediate professional assistance.
Here are some of the most frequent furnace noises and what they might be signaling. If your furnace is making an odd noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Saint Louis, Missouri.
1. Furnace Making a Banging Noise
You might have an urgent situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be a couple of problems. These involve gas accumulating in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy over the years, so that’s why it’s critical to set annual furnace maintenance with Morgner Inc. Air Conditioning & Heating. One of the tasks our techs complete during this work is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise when ignition takes more time. The following gas buildup may fracture your furnace’s heat exchanger, where natural gas changes into heat. Any cracks in it can discharge carbon monoxide, which is normally emitted outside. This hazardous gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Morgner Inc. Air Conditioning & Heating recommends turning it off and contacting us at 314-262-4541. Significant natural gas in your furnace or a cracked heat exchanger are serious problems that should get fast service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move hot air across your house. If the ductwork wasn’t put in properly or is getting dated, it can be noisy when your furnace is heating. This could be the case if your furnace makes a banging noise when it shuts off. Contact Morgner Inc. Air Conditioning & Heating at 314-262-4541 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t delay calling 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 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 chilly air across your house, and a capacitor, which turns on the motor. If either of these components are fading, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be due to something little, like an unfastened screw, or something major, like a broken part. In either case, we recommend shutting off your furnace and contacting our heating specialists at 314-262-4541 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 alert you it needs some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing may need to be lubed. We realize that maintenance sometimes slips your mind, but our professionals can get your furnace heating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You might also be aware of whistling while the furnace is on if a floor vent is loose. If you’ve examined your vents but are still hearing whistling, Morgner Inc. Air Conditioning & Heating can help. It’s essential to get loose ductwork repaired quickly, because it can make comfort issues in your residence and inflate your gas 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 usually means there’s trouble with your furnace’s blower. Turn off your furnace off immediately and contact our pros at 314-262-4541 for support.
