When your furnace is operating correctly, it should deliver warm air without creating too much sound. While it’s expected to hear your furnace making noise as it begins running, other noises are showing your furnace needs immediate professional support.

Here are some of the most reported furnace noises and what they can be indicating. If your furnace is making a strange noise, our friendly heating professionals are here to assist with the best furnace repair in Athol, Idaho.

1. Furnace Making a Banging Noise

You may 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 can mean 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 becomes grimy as time passes, so that’s why it’s critical to schedule yearly furnace maintenance with Alpine Summit Heating & Cooling. One of the things our technicians perform during this service is clean your furnace’s burners. When this piece gets grubby, you might hear your furnace making a loud rumbling noise after ignition takes more time. The subsequent gas buildup may break your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can discharge carbon monoxide, which is ordinarily released away from your home. This dangerous gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Alpine Summit Heating & Cooling urges you to turn it off and calling us at 208-561-1226. Too much natural gas in your furnace or a cracked heat exchanger are critical problems that should get immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver warm air across your house. If the ductwork wasn’t installed correctly or is getting dated, it can make a lot of noise when your furnace runs. This may be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Alpine Summit Heating & Cooling at 208-561-1226 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound frequently means there’s an electrical problem, 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 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 across your rooms, and a capacitor, which triggers the motor. If either of these parts are fading, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be related to something minor, like a loose screw, or something serious, like a broken part. In either case, we recommend shutting off your furnace and calling our heating professionals at 208-561-1226 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to alert you it requires some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be greased. We know that maintenance sometimes slips your mind, but our pros 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 frequently because of an air leak in your ductwork. You could also notice whistling while the furnace is on if a floor vent is loose. If you’ve examined your vents but are still sensing whistling, Alpine Summit Heating & Cooling can help. It’s critical to get loose ductwork taken care of fast, because it can result in comfort issues in your residence and inflate your utility bills.

6. Furnace Making a Grinding Noise

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal racket often means there’s a problem with your furnace’s blower. Shut down your furnace off immediately and contact our professionals at 208-561-1226 for assistance.
