When your furnace is operating correctly, it should deliver warmth without creating too much disruption. While it’s common to catch your furnace making noise as it begins running, other sounds are showing your furnace needs immediate professional support.
Here are some of the most reported furnace noises and what they might mean. If your furnace is making an odd noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Wausau, Wisconsin.
1. Furnace Makes a Banging Sound
You may have an urgent issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be several problems. These include gas accumulating in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system gets grimy over time, so that’s why it’s essential to book routine furnace maintenance with Gilray Heating and Cooling. One of the things our professionals perform 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 takes more time. The following gas buildup might break your furnace’s heat exchanger, where natural gas changes into warm air. Any breaks in it can emit carbon monoxide, which is ordinarily released outdoors. This toxic gas can be lethal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Gilray Heating and Cooling urges you to turn it off and calling us at 715-301-0727. Excessive natural gas in your furnace or a fractured heat exchanger are dangerous problems that should get prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to provide warm air throughout your house. If the ductwork wasn’t installed right or is getting old, it can be noisy when your furnace runs. This can be the issue if your furnace makes a banging noise when it shuts off. Call Gilray Heating and Cooling at 715-301-0727 and we’ll pinpoint the problem.
2. Furnace Makes a Buzzing Sound
If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate 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 uses a blower motor, which moves warm or chilly air across your space, and a capacitor, which turns on the motor. If either of these parts are going out, they will buzz when the furnace switches on.
3. Furnace Rattles
If your furnace is making a rattling noise, it may be related to something little, like an unsecure screw, or something critical, like a broken component. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at 715-301-0727 for assistance.
4. Furnace Is Making a High-Pitched Squealing Sound
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to tell you it could use some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn down or a bearing could need to be greased. We are aware that maintenance frequently slips your mind, but our pros can get your furnace running quietly again rapidly.
5. Furnace Whistles
When you’re detecting your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You might also notice whistling while the furnace is on if a floor vent isn’t secure. If you’ve looked at your vents but are still hearing noise, Gilray Heating and Cooling can assist you. It’s critical to get loose ductwork taken care of without delay, as it can create comfort issues in your residence and inflate your gas bills.
6. Furnace Making a Grinding Noise
It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal racket frequently means there’s trouble with your furnace’s blower. Turn off your furnace off promptly and contact our professionals at 715-301-0727 for help.
