When your furnace is working properly, it should deliver heat without generating too much noise. While it’s common to notice your furnace making noise as it begins running, other noises are showing your furnace should get immediate professional help.

Here are some of the most reported furnace noises and what they can be signaling. If your furnace is making an atypical noise, our friendly heating specialists are here to help with the best furnace repair in Bishop, California.

1. Furnace Making a Banging Noise

You might 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 might indicate there could be a couple of problems. These range from gas accumulating in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty over the years, so that’s why it’s essential to set routine furnace maintenance with Bishop Heating & Air Conditioning. One of the tasks our pros complete during this appointment is clean your furnace’s burners. When this component gets grimy, you may hear your furnace making a loud rumbling noise when ignition is delayed. The ensuing gas buildup might break your furnace’s heat exchanger, where natural gas changes into heat. Any breaks in it can discharge carbon monoxide, which is ordinarily vented outside. This hazardous gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Bishop Heating & Air Conditioning recommends turning it off and contacting us at 760-784-9034. Too much natural gas in your furnace or a cracked heat exchanger are critical issues that should get fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move hot air throughout your residence. If the ductwork wasn’t installed correctly or is getting old, it can be loud when your furnace is heating. This may be the case if your furnace makes a banging noise when it shuts off. Get in touch with Bishop Heating & Air Conditioning at 760-784-9034 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound typically is telling you there’s an electrical situation, 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 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 turns on the motor. If either of these parts are fading, they will buzz when the furnace turns on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it may be due to something small, like an unfastened screw, or something critical, like a broken part. In either case, we advise shutting your furnace off and getting in touch with our heating professionals at 760-784-9034 for assistance.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to tell you it could use some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing may need to be lubed. We realize that maintenance frequently slips your mind, but our techs can get your furnace operating quietly again quickly.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You could also notice whistling while the furnace is running if a floor vent isn’t tight. If you’ve examined your vents but are still noticing noise, Bishop Heating & Air Conditioning can help. It’s critical to get loose ductwork fixed fast, as it can create comfort problems in your home and increase your gas 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 sound usually means there’s trouble with your furnace’s blower. Turn off your furnace off right away and call our professionals at 760-784-9034 for support.
