When your furnace is working properly, it should deliver warmth without making too much disruption. While it’s expected to catch your furnace making noise as it begins running, other noises are showing your furnace requires immediate professional assistance.
Here are some of the most common furnace noises and what they might be indicating. If your furnace is making a weird noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Athol, Idaho.
1. Furnace Making a Banging Noise
You could have an urgent issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a few problems. These involve gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy over the years, so that’s why it’s critical to book annual furnace maintenance with Alpine Summit Heating & Cooling. One of the tasks our techs perform during this service is clean your furnace’s burners. When this piece gets dirty, you could hear your furnace making a loud rumbling noise when ignition is delayed. The resulting gas buildup may crack your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can discharge 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, Alpine Summit Heating & Cooling advises turning it off and contacting us at 208-561-1226. Too much natural gas in your furnace or a fractured heat exchanger are dangerous problems that should get fast service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver heated air throughout your home. If the ductwork wasn’t designed properly or is aging, it can be noisy when your furnace runs. This may be the case if your furnace makes a banging noise when it shuts off. Call Alpine Summit Heating & Cooling at 208-561-1226 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to work on the right voltage. If wires or the box needs to be tightened, you may notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes warm or cooled air across your residence, and a capacitor, which starts the motor. If either of these components 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 related to something little, like a loose screw, or something major, like a broken part. In either case, we recommend shutting off your furnace and getting in touch with our heating professionals at 208-561-1226 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to alert you it needs some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing may need to be greased. We are aware that maintenance frequently slips your mind, but our techs can get your furnace running quietly again fast.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You may also be aware of whistling while the furnace is operating if a floor vent isn’t tight. If you’ve examined your vents but are still sensing noise, Alpine Summit Heating & Cooling can assist you. It’s important to get loose ductwork taken care of quickly, since it can result in comfort troubles in your residence and drive up your heating bills.
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 typically means there’s a problem with your furnace’s blower. Turn off your furnace off right away and call our pros at 208-561-1226 for help.
