When your furnace is operating like it should, it should give warm air without making too much disruption. While it’s expected to notice your furnace making noise as it begins running, other disruptions are indicating your furnace should get immediate professional support.

Here are some of the most reported furnace noises and what they could be indicating. If your furnace is making a weird noise, our friendly heating specialists are here to help with the best furnace repair in Mobile, Alabama.

1. Furnace Making a Banging Noise

You might have an urgent situation 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 a few problems. These include gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty as time passes, so that’s why it’s essential to book routine furnace maintenance with Farnell Heating & Air Conditioning Inc. One of the things our pros do during this appointment is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise if ignition takes longer than normal. The following gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can emit carbon monoxide, which is regularly released outside. This toxic gas can be lethal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Farnell Heating & Air Conditioning Inc urges you to turn it off and reaching us at 251-471-2674. Excessive natural gas in your furnace or a ruptured heat exchanger are critical problems that necessitate prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide heated air around your house. If the ductwork wasn’t installed properly or is aging, it can be loud when your furnace is on. This may be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Farnell Heating & Air Conditioning Inc at 251-471-2674 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound typically means there’s an electrical issue, 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 works with a blower motor, which sends heated or cold air across your house, and a capacitor, which starts the motor. If either of these pieces 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 could be the result of something minor, like a loose screw, or something critical, like a broken piece. In either case, we recommend shutting off your furnace and contacting our heating professionals at 251-471-2674 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to alert you it needs some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be greased. We are aware that maintenance frequently slips your mind, but our technicians 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 likely the result of an air leak in your ductwork. You could also hear whistling while the furnace is working if a floor vent isn’t tight. If you’ve checked your vents but are still hearing sound, Farnell Heating & Air Conditioning Inc can provide support. It’s important to get loose ductwork repaired without delay, since it can make comfort issues in your home and increase your gas bills.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal racket typically means there’s an issue with your furnace’s blower. Shut down your furnace off instantly and contact us at 251-471-2674 for support.
