When your furnace is working correctly, it should give warm air without making too much disruption. While it’s expected to catch your furnace making noise as it starts up, other sounds are signaling your furnace should get immediate professional assistance.

Here are some of the most reported furnace noises and what they might be indicating. If your furnace is making an odd noise, our friendly heating pros are here to help with the best furnace repair in Cache Valley, Utah.

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 may signal 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 essential to book seasonal furnace maintenance with Western Mechanical, Inc.. One of the tasks our pros complete during this work is clean your furnace’s burners. When this piece gets grimy, you could hear your furnace making a loud rumbling noise after ignition takes more time. The following gas buildup can fracture your furnace’s heat exchanger, where natural gas transforms into warm air. Any cracks in it can leak carbon monoxide, which is regularly emitted outdoors. This hazardous gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Western Mechanical, Inc. urges you to turn it off and contacting us at 435-753-5515. Significant natural gas in your furnace or a ruptured heat exchanger are critical issues that necessitate fast service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide hot air around your home. If the ductwork wasn’t installed properly or is getting dated, it can make a lot of noise when your furnace runs. This may be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Western Mechanical, Inc. at 435-753-5515 and we’ll determine the problem.

2. Furnace Makes a Buzzing Sound

If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually 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 right voltage. If wires or the box is loose, you could hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves heated or cooled air across your rooms, and a capacitor, which triggers the motor. If either of these pieces 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 the result of something minor, like an unfastened screw, or something critical, like a broken part. In either case, we recommend shutting off your furnace and contacting our heating pros at 435-753-5515 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 could use some TLC. If you’ve neglected furnace maintenance recently, belts could be worn down or a bearing might need to be lubricated. We are aware that maintenance frequently slips your mind, but our pros can get your furnace operating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You may also hear whistling while the furnace is operating if a floor vent is loose. If you’ve examined your vents but are still hearing noise, Western Mechanical, Inc. can help. It’s essential to get loose ductwork taken care of fast, as it can create comfort troubles in your residence and drive up your heating expenses.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal sound frequently means there’s a problem with your furnace’s blower. Switch off your furnace off immediately and call our pros at 435-753-5515 for support.
