When your furnace is operating properly, it should give heat without generating too much noise. While it’s normal to hear your furnace making noise as it turns on, other sounds are showing your furnace requires immediate professional support.

Here are some of the most frequent furnace noises and what they could mean. If your furnace is making a weird noise, our friendly heating pros are here to help with the best furnace repair in Bishop, California.

1. Furnace Making a Banging Noise

You might have an urgent situation on your hands if you’re noticing 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 increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy as time passes, so that’s why it’s critical to set routine furnace maintenance with Bishop Heating & Air Conditioning. One of the jobs our pros do during this appointment is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise if ignition is delayed. The ensuing gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can discharge carbon monoxide, which is regularly released outside. This hazardous gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Bishop Heating & Air Conditioning recommends turning it off and calling us at 760-784-9034. Significant natural gas in your furnace or a cracked heat exchanger are dangerous troubles that necessitate immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver heated air around your residence. If the ductwork wasn’t installed correctly or is getting dated, it can be loud when your furnace is heating. This may be the issue 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 observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to run on the proper voltage. If wires or the box needs to be tightened, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes heated or cold air throughout your residence, and a capacitor, which starts the motor. If either of these parts are failing, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be related to something little, like an unfastened screw, or something critical, like a broken component. In either case, we urge you to shut your furnace off and calling our heating professionals at 760-784-9034 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to get your attention it needs some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be lubricated. We realize that maintenance often slips your mind, but our technicians can get your furnace running quietly again fast.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You could also be aware of whistling while the furnace is on if a floor vent isn’t secure. If you’ve examined your vents but are still noticing sound, Bishop Heating & Air Conditioning can assist you. It’s important to get loose ductwork fixed fast, because it can create comfort troubles in your home and increase your heating 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 an issue with your furnace’s blower. Turn off your furnace off right away and contact us at 760-784-9034 for assistance.
