When your furnace is operating like it should, it should give warm air without creating too much sound. While it’s common to catch your furnace making noise as it turns on, other sounds are indicating your furnace needs immediate professional assistance.

Here are some of the most reported furnace noises and what they might mean. If your furnace is making a strange noise, our friendly heating pros are here to assist with the best furnace repair in West Jefferson, Ohio.

1. Furnace Making a Banging Noise

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

Banging Sounds Coming from Your Furnace

Your heating system gets dirty over the years, so that’s why it’s critical to set annual furnace maintenance with West Jefferson Plumbing and Heating, Inc.. One of the tasks our professionals complete during this service is clean your furnace’s burners. When this piece gets dirty, you might hear your furnace making a loud rumbling noise if ignition takes longer than normal. The resulting gas buildup might crack your furnace’s heat exchanger, where natural gas transforms into warmth. Any breaks in it can emit carbon monoxide, which is regularly released outdoors. This toxic gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, West Jefferson Plumbing and Heating, Inc. advises turning it off and reaching us at 614-879-9091. Significant natural gas in your furnace or a fractured heat exchanger are serious problems that should get immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move warm air across your house. If the ductwork wasn’t installed right or is getting dated, it can be loud when your furnace is on. This may be the case if your furnace makes a banging noise when it shuts off. Get in touch with West Jefferson Plumbing and Heating, Inc. at 614-879-9091 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound often means there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run on the right voltage. If wires or the box isn’t tight enough, you may hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes hot or cooled air throughout your home, and a capacitor, which triggers the motor. If either of these pieces are going out, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be due to something little, like an unfastened screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and contacting our heating professionals at 614-879-9091 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to alert you it needs some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing could need to be lubed. We are aware that maintenance often slips your mind, but our technicians can get your furnace operating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You may also notice whistling while the furnace is running if a floor vent is loose. If you’ve looked at your vents but are still sensing sound, West Jefferson Plumbing and Heating, Inc. can assist you. It’s important to get loose ductwork repaired quickly, since it can make comfort problems in your house and drive up your energy costs.

6. Furnace Making a Grinding Noise

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal racket frequently means there’s an issue with your furnace’s blower. Shut down your furnace off now and reach our professionals at 614-879-9091 for assistance.
