When your furnace is working properly, it should give warm air without making too much noise. While it’s expected to catch your furnace making noise as it begins running, other disruptions are signaling your furnace requires immediate professional assistance.
Here are some of the most common furnace noises and what they could mean. If your furnace is making a weird noise, our friendly heating specialists are here to assist with the best furnace repair in Wausau, Wisconsin.
1. Furnace Makes Banging or Knocking Sounds
You could 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 can mean there could be several problems. These involve gas increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system gets filthy as time passes, so that’s why it’s essential to schedule routine furnace maintenance with Gilray Heating and Cooling. One of the things our technicians perform during this work is clean your furnace’s burners. When this piece gets grimy, you might hear your furnace making a loud rumbling noise after ignition takes more time. The ensuing gas buildup may fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can emit carbon monoxide, which is normally emitted outdoors. This dangerous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Gilray Heating and Cooling recommends turning it off and calling us at 715-301-0727. Significant natural gas in your furnace or a fractured heat exchanger are serious issues that require immediate attention.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver heated air across your house. If the ductwork wasn’t installed properly or is aging, it can make a lot of noise when your furnace is on. This could be the case if your furnace makes a banging noise when it shuts off. Contact Gilray Heating and Cooling at 715-301-0727 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to run on the correct voltage. If wires or the box isn’t tight enough, you may notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves heated or cold air throughout your home, and a capacitor, which turns on the motor. If either of these pieces are failing, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be due to something little, like an unfastened screw, or something serious, like a broken component. In either case, we recommend shutting off your furnace and calling our heating pros 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 on, it’s trying to alert you it requires 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 lubed. We are aware that maintenance frequently 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 likely the result of an air leak in your ductwork. You might also be aware of whistling while the furnace is operating if a floor vent is loose. If you’ve looked at your vents but are still hearing sound, Gilray Heating and Cooling can assist you. It’s important to get loose ductwork repaired without delay, because it can create comfort troubles in your house and increase your heating costs.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal racket usually means there’s an issue with your furnace’s blower. Turn off your furnace off instantly and reach our professionals at 715-301-0727 for support.
