When your furnace is working like it should, it should deliver heat without making too much noise. While it’s normal to hear your furnace making noise as it begins running, other sounds are showing your furnace needs immediate professional help.

Here are some of the most frequent furnace noises and what they could be signaling. If your furnace is making a weird noise, our friendly heating pros are here to help with the best furnace repair in Booneville, Mississippi.

1. Furnace Makes Banging or Knocking Sounds

You may 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 might mean there could be several problems. These involve gas increasing in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy over the years, so that’s why it’s essential to schedule annual furnace maintenance with Booneville Heating & Cooling. One of the jobs our technicians perform during this work is clean your furnace’s burners. When this component gets dirty, you might hear your furnace making a loud rumbling noise after ignition takes longer than normal. The resulting gas buildup can crack your furnace’s heat exchanger, where natural gas changes into warmth. Any cracks in it can discharge carbon monoxide, which is regularly emitted outdoors. This toxic gas can be lethal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Booneville Heating & Cooling recommends turning it off and reaching us at 662-269-8716. Too much natural gas in your furnace or a cracked heat exchanger are serious troubles that should get prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver warm air across your residence. If the ductwork wasn’t put in properly or is getting old, it can be noisy when your furnace is on. This can be the problem if your furnace makes a banging noise when it shuts off. Contact Booneville Heating & Cooling at 662-269-8716 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently indicates an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to run on the right voltage. If wires or the box needs to be tightened, you could hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends hot or chilly air around your residence, and a capacitor, which turns on the motor. If either of these components are going out, they will buzz when the furnace starts.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it can be the result of something small, like a loose screw, or something critical, like a broken part. In either case, we recommend shutting off your furnace and getting in touch with our heating professionals at 662-269-8716 for help.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to get your attention it could use some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn down or a bearing may need to be lubricated. We realize that maintenance sometimes slips your mind, but our technicians can get your furnace running quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You may also be aware of whistling while the furnace is running if a floor vent isn’t secure. If you’ve checked your vents but are still sensing noise, Booneville Heating & Cooling can assist you. It’s critical to get loose ductwork taken care of without delay, since it can result in comfort issues in your residence and inflate your gas bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal racket often means there’s an issue with your furnace’s blower. Shut down your furnace off promptly and contact our pros at 662-269-8716 for help.
