When your furnace is operating correctly, it should deliver warmth without generating too much disruption. While it’s expected to catch your furnace making noise as it turns on, other sounds are signaling your furnace requires immediate professional assistance.
Here are some of the most common furnace noises and what they might be indicating. If your furnace is making an odd noise, our friendly heating professionals are here to assist with the best furnace repair in Rock Hill, South Carolina.
1. Furnace Making a Banging Noise
You might have a critical problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be several problems. These involve gas increasing in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system becomes dirty as time passes, so that’s why it’s essential to set seasonal furnace maintenance with US Air Heating and Cooling. One of the things our pros complete during this appointment is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise after ignition takes more time. The subsequent gas buildup may crack your furnace’s heat exchanger, where natural gas transforms into warm air. Any fractures in it can leak carbon monoxide, which is normally released away from your home. This dangerous gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, US Air Heating and Cooling advises turning it off and contacting us at 803-220-0761. Too much natural gas in your furnace or a fractured heat exchanger are serious issues that should get fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver hot air around your home. If the ductwork wasn’t designed right or is getting old, it can be loud when your furnace is on. This may be the case if your furnace makes a banging noise when it shuts off. Get in touch with US Air Heating and Cooling at 803-220-0761 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to run on the correct voltage. If wires or the box needs to be tightened, you could hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends hot or cold air across your space, 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 the result of something small, like an unsecure screw, or something serious, like a broken part. In either case, we advise shutting your furnace off and contacting our heating pros at 803-220-0761 for assistance.
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 requires some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing may need to be lubricated. We are aware that maintenance often 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 because of an air leak in your ductwork. You may also hear whistling while the furnace is operating if a floor vent is loose. If you’ve examined your vents but are still hearing whistling, US Air Heating and Cooling can provide support. It’s critical to get loose ductwork taken care of without delay, as it can create comfort problems in your residence and inflate your gas expenses.
6. Furnace Making a Grinding Noise
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal noise often means there’s an issue with your furnace’s blower. Turn off your furnace off promptly and contact our pros at 803-220-0761 for assistance.
