When your furnace is operating properly, it should provide warm air without creating too much noise. While it’s normal to hear your furnace making noise as it begins running, other noises are signaling your furnace needs immediate professional support.

Here are some of the most reported furnace noises and what they might mean. If your furnace is making an atypical noise, our friendly heating specialists are here to help with the best furnace repair in Booneville, Mississippi.

1. Furnace Making a Banging Noise

You may have a critical problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a couple of problems. These range from gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty over time, so that’s why it’s critical to set seasonal furnace maintenance with Booneville Heating & Cooling. One of the jobs our professionals perform during this appointment is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise after ignition is delayed. The ensuing gas buildup may crack your furnace’s heat exchanger, where natural gas changes into warm air. Any breaks in it can discharge carbon monoxide, which is ordinarily released away from your home. This dangerous gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Booneville Heating & Cooling advises turning it off and contacting us at 662-269-8716. Significant natural gas in your furnace or a fractured heat exchanger are dangerous issues that should get immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide heated air around your house. If the ductwork wasn’t designed properly or is getting old, it can be noisy when your furnace is heating. This may be the issue if your furnace makes a banging noise when it shuts off. Contact Booneville Heating & Cooling at 662-269-8716 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 usually means there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to operate on the correct voltage. If wires or the box needs to be tightened, you could notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes heated or chilly air throughout your space, and a capacitor, which triggers the motor. If either of these parts are fading, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be related to something small, like an unfastened screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at 662-269-8716 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to alert you it could use some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing may need to be greased. We realize 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 due to an air leak in your ductwork. You may also notice whistling while the furnace is working if a floor vent is loose. If you’ve checked your vents but are still hearing whistling, Booneville Heating & Cooling can provide support. It’s essential to get loose ductwork taken care of quickly, since it can create comfort issues in your residence and increase your utility costs.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal noise typically means there’s an issue with your furnace’s blower. Switch off your furnace off now and contact our pros at 662-269-8716 for help.
