When your furnace is working like it should, it should give warmth without creating too much sound. While it’s expected to catch your furnace making noise as it starts up, other noises are showing your furnace requires immediate professional support.
Here are some of the most common furnace noises and what they could be signaling. If your furnace is making a strange noise, our friendly heating specialists are here to help with the best furnace repair in Thedford, Ontario.
1. Furnace Makes Banging or Knocking Sounds
You might have a serious issue on your hands if you’re noticing 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 increasing in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy over the years, so that’s why it’s essential to book annual furnace maintenance with Taylor's Heating & Air Conditioning. One of the tasks our pros complete during this service is clean your furnace’s burners. When this part gets dirty, you could hear your furnace making a loud rumbling noise when ignition takes more time. The subsequent gas buildup may fracture your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can emit carbon monoxide, which is ordinarily emitted outside. This dangerous gas can be fatal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Taylor's Heating & Air Conditioning recommends turning it off and contacting us at 519-296-4437. Excessive natural gas in your furnace or a fractured heat exchanger are critical troubles that require immediate service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver hot air across your home. If the ductwork wasn’t put in right or is aging, it can be noisy when your furnace is heating. This could be the issue if your furnace makes a banging noise when it shuts off. Call Taylor's Heating & Air Conditioning at 519-296-4437 and we’ll determine the problem.
2. Furnace Makes a Buzzing Sound
If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often means there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to work on the right 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 warm or chilly air across your space, and a capacitor, which triggers the motor. If either of these pieces are failing, 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 small, like an unfastened screw, or something critical, like a broken piece. In either case, we recommend shutting off your furnace and getting in touch with our heating professionals at 519-296-4437 for help.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to tell you it requires some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing may need to be lubed. We are aware that maintenance frequently slips your mind, but our technicians can get your furnace running quietly again fast.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re detecting your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You may also hear whistling while the furnace is running if a floor vent is loose. If you’ve examined your vents but are still noticing whistling, Taylor's Heating & Air Conditioning can provide support. It’s critical to get loose ductwork taken care of quickly, because it can result in comfort issues in your house and increase your heating bills.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal racket typically means there’s a problem with your furnace’s blower. Shut down your furnace off immediately and reach our pros at 519-296-4437 for support.
