When your furnace is operating like it should, it should give warm air without making too much disruption. While it’s common to hear your furnace making noise as it begins running, other disruptions are showing your furnace needs immediate professional support.

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

1. Furnace Making a Banging Noise

You might have a serious issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be several problems. These involve gas building up in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty over time, so that’s why it’s important to schedule yearly furnace maintenance with Booneville Heating & Cooling. One of the things our professionals perform during this service is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise after ignition takes more time. The resulting gas buildup can crack your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can emit carbon monoxide, which is normally emitted outside. This hazardous gas can be deadly in large concentrations.

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

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver heated air around your residence. If the ductwork wasn’t designed correctly or is getting dated, it can be noisy when your furnace runs. This could be the issue if your furnace makes a banging noise when it shuts off. Call Booneville Heating & Cooling at 662-269-8716 and we’ll pinpoint 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 operate on the correct 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 moves heated or chilly air across your house, and a capacitor, which triggers the motor. If either of these parts are going out, they will buzz when the furnace turns on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it can be the result of something minor, like an unfastened screw, or something major, like a broken part. In either case, we advise shutting your furnace off and contacting 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 trying to alert you 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 lubed. We realize that maintenance sometimes slips your mind, but our techs can get your furnace running quietly again fast.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You could also notice whistling while the furnace is running if a floor vent is loose. If you’ve checked your vents but are still noticing sound, Booneville Heating & Cooling can assist you. It’s important to get loose ductwork repaired fast, since it can make comfort troubles in your house and increase your energy 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 noise usually means there’s an issue with your furnace’s blower. Turn off your furnace off now and contact us at 662-269-8716 for assistance.
