When your furnace is working like it should, it should deliver warmth without generating too much disruption. While it’s normal to hear your furnace making noise as it begins running, other disruptions are signaling your furnace should get immediate professional help.

Here are some of the most common furnace noises and what they could mean. If your furnace is making an odd noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Columbia, Mississippi.

1. Furnace Making a Banging Noise

You may have an urgent situation 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 few problems. These range from gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy as time passes, so that’s why it’s important to book yearly furnace maintenance with Watts Electric & AC. One of the things our pros do during this appointment is clean your furnace’s burners. When this part gets grubby, you may hear your furnace making a loud rumbling noise when ignition takes more time. The ensuing gas buildup may break your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can leak carbon monoxide, which is normally vented outside. This hazardous gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Watts Electric & AC urges you to turn it off and reaching us at 601-736-7362. Excessive natural gas in your furnace or a fractured heat exchanger are dangerous problems that necessitate prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver hot air throughout your residence. If the ductwork wasn’t designed right or is getting dated, it can be noisy when your furnace is heating. This may be the case if your furnace makes a banging noise when it shuts off. Get in touch with Watts Electric & AC at 601-736-7362 and we’ll determine the problem.

2. Furnace Makes a Buzzing Sound

If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually is telling you 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 might hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or chilly air around your house, and a capacitor, which turns on 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 may be the result of something little, like an unfastened screw, or something serious, like a broken part. In either case, we urge you to shut your furnace off and contacting our heating specialists at 601-736-7362 for assistance.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to get your attention it needs some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing might need to be lubricated. We know that maintenance sometimes slips your mind, but our techs can get your furnace heating quietly again quickly.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You may also hear whistling while the furnace is working if a floor vent isn’t tight. If you’ve looked at your vents but are still noticing whistling, Watts Electric & AC can help. It’s essential to get loose ductwork repaired fast, because it can result in comfort issues in your home and inflate your energy costs.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal sound often means there’s an issue with your furnace’s blower. Turn off your furnace off instantly and reach our professionals at 601-736-7362 for support.
