When your furnace is running properly, it should give heat without creating too much disruption. While it’s common to hear your furnace making noise as it starts up, other disruptions are indicating your furnace needs 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 professionals are here to assist with the best furnace repair in Eastland, Texas.

1. Furnace Makes a Banging Sound

You might have a critical problem 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 couple of problems. These involve gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty over time, so that’s why it’s important to set annual furnace maintenance with J & J Air Conditioning. One of the tasks our technicians do during this work is clean your furnace’s burners. When this part gets grimy, you may hear your furnace making a loud rumbling noise if ignition takes longer than normal. The following gas buildup can crack your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can leak carbon monoxide, which is normally emitted outside. This dangerous gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, J & J Air Conditioning urges you to turn it off and reaching us at 254-355-3833. Excessive natural gas in your furnace or a fractured heat exchanger are serious troubles that require prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move hot air throughout your home. If the ductwork wasn’t installed correctly or is getting old, it can be loud when your furnace is heating. This might be the issue if your furnace makes a banging noise when it shuts off. Call J & J Air Conditioning at 254-355-3833 and we’ll pinpoint the problem.

2. Furnace Makes a Buzzing Sound

If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to operate on the proper voltage. If wires or the box is loose, you might hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes warm or chilly air around your rooms, and a capacitor, which starts the motor. If either of these parts are failing, 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 the result of something small, like a loose screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and contacting our heating professionals at 254-355-3833 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to get your attention it needs some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn down or a bearing could need to be greased. We know that maintenance sometimes slips your mind, but our professionals can get your furnace heating quietly again fast.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You could also hear whistling while the furnace is operating if a floor vent isn’t secure. If you’ve examined your vents but are still noticing noise, J & J Air Conditioning can provide support. It’s critical to get loose ductwork repaired fast, since it can result in comfort problems in your house and increase your heating bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal sound typically means there’s a problem with your furnace’s blower. Shut down your furnace off instantly and contact our professionals at 254-355-3833 for support.
