When your furnace is working correctly, it should give warmth without generating too much noise. While it’s common to catch your furnace making noise as it starts up, other disruptions are showing your furnace needs immediate professional help.
Here are some of the most reported furnace noises and what they might be signaling. If your furnace is making an odd noise, our friendly heating specialists are here to assist with the best furnace repair in Thedford, ON.
1. Furnace Making a Banging Noise
You might have a serious situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be a couple of problems. These range from gas increasing in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system becomes filthy as time passes, so that’s why it’s essential to book seasonal furnace maintenance with Taylor's Heating & Air Conditioning. One of the jobs our professionals do during this service is clean your furnace’s burners. When this component gets grimy, you may hear your furnace making a loud rumbling noise when ignition takes more time. The following gas buildup might break your furnace’s heat exchanger, where natural gas turns into heat. Any fractures in it can emit carbon monoxide, which is ordinarily released outside. This hazardous gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Taylor's Heating & Air Conditioning urges you to turn it off and calling us at 519-296-4437. Too much natural gas in your furnace or a ruptured heat exchanger are serious issues that should get prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver warm air throughout your house. If the ductwork wasn’t installed correctly or is getting old, it can be loud when your furnace is heating. This might be the case 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 Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound typically is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to work on the proper voltage. If wires or the box needs to be tightened, you could notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes hot or cold air around your home, and a capacitor, which starts the motor. If either of these pieces 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 can be the result of something little, like an unfastened screw, or something serious, like a broken part. In either case, we recommend shutting off your furnace and contacting our heating pros at 519-296-4437 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to tell you it could use some TLC. If you’ve neglected furnace maintenance recently, belts could be dilapidated or a bearing might need to be lubed. We realize that maintenance sometimes slips your mind, but our technicians can get your furnace heating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent isn’t secure. If you’ve looked at your vents but are still noticing sound, Taylor's Heating & Air Conditioning can help. It’s essential to get loose ductwork fixed without delay, as it can make comfort problems in your residence and drive up your utility bills.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal sound frequently means there’s trouble with your furnace’s blower. Switch off your furnace off promptly and reach our pros at 519-296-4437 for support.
