When your furnace is running properly, it should provide heat without making too much noise. While it’s common to notice your furnace making noise as it begins running, other sounds are signaling your furnace should get immediate professional assistance.

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

1. Furnace Making a Banging Noise

You might have a critical situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be several problems. These include gas increasing in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy over time, so that’s why it’s important to set seasonal furnace maintenance with JBR Mechanical. One of the jobs our professionals complete during this work is clean your furnace’s burners. When this piece gets grubby, you may hear your furnace making a loud rumbling noise if ignition takes more time. The subsequent gas buildup can crack your furnace’s heat exchanger, where natural gas transforms into warm air. Any fractures in it can discharge carbon monoxide, which is normally vented outside. This hazardous gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, JBR Mechanical urges you to turn it off and reaching us at 812-266-9785. Excessive natural gas in your furnace or a fractured heat exchanger are critical issues that should get fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide hot air throughout your house. If the ductwork wasn’t put in correctly or is getting old, it can make a lot of noise when your furnace is on. This can be the issue if your furnace makes a banging noise when it shuts off. Contact JBR Mechanical at 812-266-9785 and we’ll determine the problem.

2. Furnace Makes a Buzzing Sound

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

Your furnace uses an internal transformer to operate on the correct 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 has a blower motor, which distributes hot or cooled air throughout your residence, and a capacitor, which triggers the motor. If either of these pieces are fading, 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 small, like a loose screw, or something serious, like a broken component. In either case, we recommend shutting off your furnace and getting in touch with our heating specialists at 812-266-9785 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to alert you it could use some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing could need to be greased. We are aware that maintenance often slips your mind, but our technicians can get your furnace operating quietly again rapidly.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You might also notice whistling while the furnace is working if a floor vent isn’t tight. If you’ve examined your vents but are still hearing noise, JBR Mechanical can provide support. It’s critical to get loose ductwork repaired without delay, as it can create comfort troubles in your residence and increase your energy bills.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal racket usually means there’s a problem with your furnace’s blower. Shut down your furnace off right away and reach us at 812-266-9785 for support.
