When your furnace is operating properly, it should deliver heat without generating too much disruption. While it’s normal to notice your furnace making noise as it starts up, other noises are indicating your furnace needs immediate professional help.
Here are some of the most frequent furnace noises and what they might be indicating. If your furnace is making an atypical noise, our friendly heating specialists are here to assist with the best furnace repair in Wausau, WI.
1. Furnace Making a Banging Noise
You could have an urgent problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be several problems. These involve gas accumulating in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy over the years, so that’s why it’s critical to book yearly furnace maintenance with Gilray Heating and Cooling. One of the things our technicians perform during this appointment is clean your furnace’s burners. When this piece gets grubby, you might hear your furnace making a loud rumbling noise after ignition takes longer than normal. The subsequent gas buildup can crack your furnace’s heat exchanger, where natural gas turns into warmth. Any fractures in it can discharge carbon monoxide, which is ordinarily emitted away from your home. This hazardous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Gilray Heating and Cooling advises turning it off and contacting us at 715-301-0727. Excessive natural gas in your furnace or a cracked heat exchanger are hazardous problems that should get immediate attention.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver warm air around your home. If the ductwork wasn’t designed right or is getting dated, it can be noisy when your furnace is heating. This may 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 Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t hesitate to call 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 run on the right voltage. If wires or the box isn’t tight enough, you could detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or cold air throughout your residence, and a capacitor, which starts the motor. If either of these parts are fading, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it can be the result of something minor, like an unsecure screw, or something major, like a broken part. In either case, we recommend shutting off your furnace and getting in touch with our heating specialists at 715-301-0727 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to alert you it could use some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing may need to be lubricated. We realize that maintenance often slips your mind, but our techs can get your furnace operating quietly again quickly.
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 on if a floor vent isn’t secure. If you’ve looked at your vents but are still sensing whistling, Gilray Heating and Cooling can help. It’s important to get loose ductwork fixed without delay, since it can create comfort problems in your residence and inflate your energy expenses.
6. Furnace Making a Grinding Noise
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal noise frequently means there’s a problem with your furnace’s blower. Turn off your furnace off instantly and contact our pros at 715-301-0727 for help.
