When your furnace is working properly, it should give warm air without creating too much noise. While it’s normal to notice your furnace making noise as it turns on, other disruptions are signaling 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 an atypical noise, our friendly heating pros are here to assist with the best furnace repair in Booneville, Mississippi.

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 can indicate there could be a couple of problems. These include gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty over time, so that’s why it’s important to set yearly furnace maintenance with Booneville Heating & Cooling. One of the things our techs perform during this service is clean your furnace’s burners. When this part gets dirty, you might hear your furnace making a loud rumbling noise when ignition is delayed. The resulting gas buildup can crack your furnace’s heat exchanger, where natural gas turns into warmth. Any fractures in it can discharge carbon monoxide, which is regularly vented away from your home. This hazardous gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Booneville Heating & Cooling recommends turning it off and contacting us at 662-269-8716. Too much natural gas in your furnace or a fractured heat exchanger are critical issues that require fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide hot air throughout your house. If the ductwork wasn’t designed right or is getting dated, it can make a lot of noise when your furnace runs. This can 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 determine the problem.

2. Furnace Making a Buzzing Noise

If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound often indicates an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to operate on the right voltage. If wires or the box isn’t tight enough, you could notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends warm or cooled air throughout your house, and a capacitor, which triggers the motor. If either of these pieces are failing, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be related to something little, like an unsecure screw, or something major, like a broken component. In either case, we urge you to shut your furnace off and calling 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 going, it’s making an effort to tell you it needs some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be lubricated. We know that maintenance sometimes slips your mind, but our professionals can get your furnace heating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You may also hear whistling while the furnace is operating 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 important to get loose ductwork fixed quickly, because it can make comfort troubles in your house and drive up your utility expenses.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal sound frequently means there’s an issue with your furnace’s blower. Switch off your furnace off promptly and reach our pros at 662-269-8716 for help.
