When your furnace is running correctly, it should provide warmth without creating too much disruption. While it’s expected to notice your furnace making noise as it starts up, other disruptions are signaling your furnace needs immediate professional help.
Here are some of the most common furnace noises and what they might be signaling. If your furnace is making an odd noise, our friendly heating pros are here to fix the problem with the best furnace repair in Macon, GA.
1. Furnace Making a Banging Noise
You could have a critical problem 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 several problems. These range from gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system becomes filthy over the years, so that’s why it’s critical to schedule yearly furnace maintenance with Air Temperature Control. One of the things our techs do during this appointment is clean your furnace’s burners. When this part gets grimy, you could hear your furnace making a loud rumbling noise when ignition is delayed. The subsequent gas buildup may break your furnace’s heat exchanger, where natural gas turns into heat. Any breaks in it can emit carbon monoxide, which is ordinarily released away from your home. This dangerous gas can be deadly in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Air Temperature Control recommends turning it off and reaching us at 478-202-3170. Too much natural gas in your furnace or a cracked heat exchanger are critical issues that necessitate immediate repairs.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver hot air across your house. If the ductwork wasn’t designed correctly or is getting old, it can be noisy when your furnace is on. This can be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Air Temperature Control at 478-202-3170 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound frequently means there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to run on the right voltage. If wires or the box needs to be tightened, you may notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes warm or chilly air around your residence, and a capacitor, which triggers the motor. If either of these pieces 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 might be the result of something small, like an unfastened screw, or something major, like a broken piece. In either case, we recommend shutting off your furnace and contacting our heating specialists at 478-202-3170 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to alert you it needs some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be lubricated. We know that maintenance frequently slips your mind, but our professionals can get your furnace operating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You could also hear whistling while the furnace is operating if a floor vent isn’t tight. If you’ve examined your vents but are still noticing sound, Air Temperature Control can assist you. It’s critical to get loose ductwork repaired without delay, since it can make comfort issues in your home and increase your energy costs.
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 noise frequently means there’s a problem with your furnace’s blower. Shut down your furnace off right away and contact our professionals at 478-202-3170 for help.
