When your furnace is operating properly, it should give warm air without making too much disruption. While it’s common to hear your furnace making noise as it turns on, other noises are showing your furnace requires immediate professional assistance.
Here are some of the most reported furnace noises and what they might be signaling. If your furnace is making an atypical noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Macon, Georgia.
1. Furnace Makes a Banging Sound
You may 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 may mean there could be several problems. These include gas building up in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets grimy over time, so that’s why it’s critical to set annual furnace maintenance with Air Temperature Control. One of the tasks our professionals complete during this service is clean your furnace’s burners. When this piece gets grubby, you could hear your furnace making a loud rumbling noise if ignition is delayed. The ensuing gas buildup may break your furnace’s heat exchanger, where natural gas changes into warm air. Any breaks in it can leak carbon monoxide, which is regularly released away from your home. This hazardous gas can be lethal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Air Temperature Control recommends turning it off and contacting us at 478-202-3170. Excessive natural gas in your furnace or a cracked heat exchanger are hazardous troubles that require prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver warm air across your house. If the ductwork wasn’t designed correctly or is getting old, it can make a lot of noise when your furnace runs. This could be the issue if your furnace makes a banging noise when it shuts off. Call Air Temperature Control at 478-202-3170 and we’ll determine the problem.
2. Furnace Makes a Buzzing Sound
If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound frequently indicates an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate on the correct voltage. If wires or the box needs to be tightened, you could detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves heated or chilly air throughout your space, and a capacitor, which starts 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 little, like an unfastened screw, or something serious, like a broken piece. In either case, we advise shutting your furnace off and getting in touch with our heating professionals 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 making an effort to alert you it needs some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing could need to be lubricated. We are aware that maintenance frequently slips your mind, but our professionals can get your furnace heating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re noticing 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 working if a floor vent is loose. If you’ve checked your vents but are still noticing whistling, Air Temperature Control can provide support. It’s important to get loose ductwork repaired fast, as it can create comfort troubles in your residence and drive up your energy costs.
6. Furnace Making a Grinding Noise
It’s not a good sign if you notice 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 now and reach our pros at 478-202-3170 for assistance.
