When your furnace is running properly, it should give warm air without generating too much sound. While it’s normal to catch your furnace making noise as it turns on, other sounds are showing your furnace needs immediate professional assistance.

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

1. Furnace Making a Banging Noise

You may have a serious issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a few problems. These include gas increasing in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty as time passes, so that’s why it’s critical 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 part gets grubby, you might hear your furnace making a loud rumbling noise when ignition takes more time. The following gas buildup can break your furnace’s heat exchanger, where natural gas transforms into warmth. Any fractures in it can emit carbon monoxide, which is ordinarily emitted outdoors. This toxic gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Bishop Heating & Air Conditioning urges you to turn it off and calling us at 760-784-9034. Significant natural gas in your furnace or a broken heat exchanger are serious troubles that require fast service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver warm air around your residence. If the ductwork wasn’t designed properly or is aging, it can be noisy when your furnace is on. This can be the case if your furnace makes a banging noise when it shuts off. Call Bishop Heating & Air Conditioning at 760-784-9034 and we’ll figure out the problem.

2. Furnace Makes a Buzzing Sound

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

Your furnace uses an internal transformer to run on the proper voltage. If wires or the box needs to be tightened, you may hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves heated or cold air across your residence, and a capacitor, which turns on the motor. If either of these components are going out, 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 major, like a broken part. In either case, we advise shutting your furnace off and calling our heating pros at 760-784-9034 for support.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to alert you it needs some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing could need to be lubed. We realize that maintenance often slips your mind, but our technicians can get your furnace operating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re detecting your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You may also be aware of whistling while the furnace is running if a floor vent is loose. If you’ve looked at your vents but are still sensing whistling, Bishop Heating & Air Conditioning can provide support. It’s important to get loose ductwork repaired without delay, as it can make comfort issues in your house and drive up your heating expenses.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal noise typically means there’s an issue with your furnace’s blower. Shut down your furnace off now and reach our professionals at 760-784-9034 for help.
