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

Here are some of the most frequent furnace noises and what they can be signaling. If your furnace is making an atypical 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 a critical situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be several problems. These include gas accumulating in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty over the years, so that’s why it’s critical to schedule routine furnace maintenance with Bishop Heating & Air Conditioning. One of the things our pros complete during this work is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise when ignition takes longer than normal. The ensuing gas buildup might break your furnace’s heat exchanger, where natural gas changes into warm air. Any breaks in it can emit carbon monoxide, which is normally emitted outdoors. This hazardous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Bishop Heating & Air Conditioning recommends turning it off and reaching us at 760-784-9034. Significant natural gas in your furnace or a fractured heat exchanger are critical issues that necessitate prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver hot air throughout your residence. If the ductwork wasn’t installed right or is getting dated, it can be noisy when your furnace is heating. This could 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 pinpoint the problem.

2. Furnace Buzzes Constantly

If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound frequently indicates an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to work on the proper voltage. If wires or the box needs to be tightened, you may detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves heated or cooled air around your rooms, and a capacitor, which triggers 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 the result of something little, like a loose screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and getting in touch with our heating professionals at 760-784-9034 for support.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to alert you it could use some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn down or a bearing could need to be lubed. We know that maintenance sometimes slips your mind, but our pros can get your furnace running quietly again fast.

5. Furnace Whistles

When you’re hearing 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 working if a floor vent isn’t secure. If you’ve examined your vents but are still sensing whistling, Bishop Heating & Air Conditioning can assist you. It’s essential to get loose ductwork repaired fast, since it can make comfort issues in your house and drive up your heating expenses.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal noise frequently means there’s an issue with your furnace’s blower. Turn off your furnace off right away and reach our pros at 760-784-9034 for help.
