When your furnace is running like it should, it should deliver warmth without creating too much noise. While it’s expected to catch your furnace making noise as it begins running, other disruptions are indicating your furnace needs immediate professional support.
Here are some of the most common furnace noises and what they can be indicating. If your furnace is making an atypical noise, our friendly heating pros are here to fix the problem with the best furnace repair in Thedford, Ontario.
1. Furnace Makes a Banging Sound
You may 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 can mean there could be a few problems. These range from gas building up in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty over time, so that’s why it’s essential to schedule seasonal furnace maintenance with Taylor's Heating & Air Conditioning. One of the tasks our professionals perform during this work is clean your furnace’s burners. When this part gets grimy, you might hear your furnace making a loud rumbling noise after ignition takes longer than normal. The resulting gas buildup may break your furnace’s heat exchanger, where natural gas turns into heat. Any fractures in it can emit carbon monoxide, which is regularly released outside. This hazardous gas can be lethal in large concentrations.
If you’re hearing 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 cracked heat exchanger are serious troubles that necessitate fast service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver warm air around your home. If the ductwork wasn’t put in correctly or is getting dated, it can make a lot of noise when your furnace runs. This could be the problem if your furnace makes a banging noise when it shuts off. Contact Taylor's Heating & Air Conditioning at 519-296-4437 and we’ll determine the problem.
2. Furnace Makes a Buzzing Sound
If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to operate on the right voltage. If wires or the box is loose, you could hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves hot or cold air throughout your residence, and a capacitor, which triggers the motor. If either of these components are going out, they will buzz when the furnace switches on.
3. Furnace Makes Rattling Sounds Like Something Is Loose
If your furnace is making a rattling noise, it could be due to something little, like an unfastened screw, or something critical, like a broken component. In either case, we advise shutting your furnace off and calling our heating professionals at 519-296-4437 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to tell you it needs some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn out or a bearing may need to be lubricated. We are aware that maintenance frequently slips your mind, but our techs can get your furnace operating quietly again fast.
5. Furnace Whistles
When you’re hearing your furnace making a whistling noise, it’s typically because of 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 whistling, Taylor's Heating & Air Conditioning can provide support. It’s essential to get loose ductwork repaired fast, because it can create comfort issues in your house and drive up your heating bills.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal sound usually means there’s an issue with your furnace’s blower. Turn off your furnace off instantly and reach our pros at 519-296-4437 for help.
