1. Furnace Making a Banging Noise
You may have a serious problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a few problems. These range from gas increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system becomes filthy over the years, so that’s why it’s important to set routine 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 component gets dirty, you might hear your furnace making a loud rumbling noise after ignition is delayed. The following gas buildup can crack your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can emit carbon monoxide, which is regularly vented outdoors. 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 calling us at 519-296-4437. Excessive natural gas in your furnace or a broken heat exchanger are hazardous problems that necessitate prompt attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move warm air across your house. If the ductwork wasn’t designed properly or is aging, it can be noisy when your furnace is on. This might be the case if your furnace makes a banging noise when it shuts off. Get in touch with Taylor's Heating & Air Conditioning at 519-296-4437 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound frequently is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to operate on the proper voltage. If wires or the box is loose, you could notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes hot or chilly air throughout your home, and a capacitor, which triggers the motor. If either of these parts are failing, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it can be due to something little, like an unsecure screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and getting in touch with 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 going, it’s attempting to get your attention it needs some TLC. If you’ve skipped furnace maintenance recently, belts could be worn out or a bearing may need to be lubricated. We know that maintenance sometimes slips your mind, but our techs can get your furnace operating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You might also hear whistling while the furnace is running if a floor vent is loose. If you’ve looked at your vents but are still noticing sound, Taylor's Heating & Air Conditioning can assist you. It’s important to get loose ductwork fixed fast, because it can result in comfort issues in your house and drive up your gas bills.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal noise typically means there’s a problem with your furnace’s blower. Switch off your furnace off right away and call our pros at 519-296-4437 for assistance.
