When your furnace is working like it should, it should provide warm air without making too much noise. While it’s normal to notice your furnace making noise as it turns on, other noises are signaling your furnace requires immediate professional assistance.

Here are some of the most frequent furnace noises and what they can be indicating. If your furnace is making a weird noise, our friendly heating pros are here to help with the best furnace repair in Temple/Belton , Texas.

1. Furnace Making a Banging Noise

You could have an urgent issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be several problems. These range from gas accumulating 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 Bell Air Conditioning Inc. One of the jobs our pros complete during this service is clean your furnace’s burners. When this part gets dirty, you might hear your furnace making a loud rumbling noise after ignition takes more time. The subsequent gas buildup may fracture your furnace’s heat exchanger, where natural gas changes into warmth. Any breaks in it can discharge carbon monoxide, which is ordinarily vented outside. This toxic gas can be lethal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Bell Air Conditioning Inc recommends turning it off and contacting us at 254-307-9572. Significant natural gas in your furnace or a cracked heat exchanger are hazardous issues that necessitate prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move heated air across your home. If the ductwork wasn’t installed properly or is getting old, it can be noisy when your furnace is on. This could be the case if your furnace makes a banging noise when it shuts off. Get in touch with Bell Air Conditioning Inc at 254-307-9572 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 issue, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to work on the correct voltage. If wires or the box is loose, you may notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves hot or cooled air across your house, and a capacitor, which starts the motor. If either of these pieces are going out, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be due to something little, like an unfastened screw, or something critical, like a broken piece. In either case, we recommend shutting off your furnace and contacting our heating specialists at 254-307-9572 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to tell you it requires some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be lubed. We know that maintenance frequently slips your mind, but our techs can get your furnace heating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You might also be aware of whistling while the furnace is working if a floor vent isn’t secure. If you’ve examined your vents but are still noticing whistling, Bell Air Conditioning Inc can help. It’s critical to get loose ductwork taken care of fast, as it can result in comfort troubles in your home and increase your heating costs.

6. Furnace Making a Grinding Noise

It’s not a positive 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 now and contact our pros at 254-307-9572 for assistance.
