When your furnace is working correctly, it should give heat without generating too much sound. While it’s common to notice your furnace making noise as it begins running, other disruptions are indicating your furnace needs immediate professional assistance.

Here are some of the most frequent furnace noises and what they could be signaling. If your furnace is making a strange noise, our friendly heating professionals are here to help with the best furnace repair in Pocatello, Idaho.

1. Furnace Makes a Banging Sound

You may have an urgent situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a few problems. These include gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy over the years, so that’s why it’s critical to book annual furnace maintenance with Vogts Heating & Air. One of the things our technicians perform during this service is clean your furnace’s burners. When this part gets grubby, you might hear your furnace making a loud rumbling noise if ignition is delayed. The subsequent gas buildup might fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any cracks in it can emit carbon monoxide, which is ordinarily released outdoors. This hazardous gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Vogts Heating & Air recommends turning it off and calling us at 208-621-0129. Too much natural gas in your furnace or a ruptured heat exchanger are hazardous problems that require immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move hot air throughout your residence. If the ductwork wasn’t put in properly or is getting old, it can be noisy when your furnace runs. This can be the case if your furnace makes a banging noise when it shuts off. Contact Vogts Heating & Air at 208-621-0129 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run on the proper voltage. If wires or the box is loose, you may notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves warm or cooled air around your home, and a capacitor, which starts the motor. If either of these parts are going out, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be the result of something minor, like an unsecure screw, or something major, like a broken piece. In either case, we advise shutting your furnace off and contacting our heating pros at 208-621-0129 for assistance.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to tell you it needs some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing might need to be lubed. We are aware that maintenance frequently slips your mind, but our technicians can get your furnace running quietly again quickly.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You might also hear whistling while the furnace is working if a floor vent is loose. If you’ve checked your vents but are still noticing sound, Vogts Heating & Air can help. It’s critical to get loose ductwork taken care of without delay, as it can result in comfort troubles in your residence and inflate your gas costs.

6. Furnace Making a 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. Turn off your furnace off immediately and reach us at 208-621-0129 for assistance.
