Banging, Screeching and Rattling: What Six Ordinary Furnace Noises Signify

When your furnace is operating like it should, it should deliver warm air without creating too much sound. While it’s expected to hear your furnace making noise as it starts up, other sounds are indicating your furnace needs immediate professional help.

Here are some of the most reported furnace noises and what they could be signaling. If your furnace is making a weird noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Moline, Illinois.

1. Furnace Making a Banging Noise

You might have an urgent issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be several problems. These range from gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy over the years, so that’s why it’s essential to set routine furnace maintenance with J.L. Brady Company LLC. One of the things our professionals perform during this service is clean your furnace’s burners. When this component gets dirty, you might hear your furnace making a loud rumbling noise when ignition is delayed. The following gas buildup can break your furnace’s heat exchanger, where natural gas turns into warmth. Any fractures in it can emit carbon monoxide, which is normally released outdoors. This toxic gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, J.L. Brady Company LLC advises turning it off and reaching us at 309-517-7511. Excessive natural gas in your furnace or a fractured heat exchanger are dangerous troubles that necessitate fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move hot air across your house. If the ductwork wasn’t put in right or is aging, it can be loud when your furnace runs. This might be the issue if your furnace makes a banging noise when it shuts off. Contact J.L. Brady Company LLC at 309-517-7511 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace relies on an internal transformer to run on the correct voltage. If wires or the box is loose, you might detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes hot or cold air around your rooms, and a capacitor, which turns on the motor. If either of these components 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 can be due to something little, like an unsecure screw, or something critical, like a broken piece. In either case, we advise shutting your furnace off and calling our heating professionals at 309-517-7511 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 alert you it needs some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing may need to be lubed. We are aware that maintenance sometimes slips your mind, but our technicians can get your furnace operating quietly again quickly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You may also hear whistling while the furnace is on if a floor vent isn’t secure. If you’ve looked at your vents but are still sensing sound, J.L. Brady Company LLC can assist you. It’s essential to get loose ductwork fixed quickly, because it can create comfort issues in your home and inflate your utility expenses.

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 racket often means there’s a problem with your furnace’s blower. Turn off your furnace off promptly and contact our professionals at 309-517-7511 for help.

When you’re getting an uncommon noise from your furnace, J.L. Brady Company LLC is ready to provide assistance. Contact us at 309-517-7511 to schedule your furnace repair appointment right away.
