When your furnace is operating correctly, it should provide warmth without making too much noise. While it’s expected to hear your furnace making noise as it turns on, other disruptions are indicating your furnace requires immediate professional support.

Here are some of the most frequent furnace noises and what they can mean. If your furnace is making a weird noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Columbia, Mississippi.

1. Furnace Making a Banging Noise

You might have an urgent issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be several problems. These include gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy over the years, so that’s why it’s essential to schedule seasonal furnace maintenance with Watts Electric & AC. One of the things our technicians do during this service is clean your furnace’s burners. When this component gets grimy, you might hear your furnace making a loud rumbling noise after ignition is delayed. The resulting gas buildup might fracture your furnace’s heat exchanger, where natural gas turns into warmth. Any breaks in it can discharge carbon monoxide, which is regularly vented away from your home. This dangerous gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Watts Electric & AC recommends turning it off and calling us at 601-736-7362. Excessive natural gas in your furnace or a fractured heat exchanger are hazardous problems that require immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move warm air across your house. If the ductwork wasn’t designed right or is aging, it can be noisy when your furnace is heating. This can be the issue if your furnace makes a banging noise when it shuts off. Contact Watts Electric & AC at 601-736-7362 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

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

Your furnace uses an internal transformer to work on the correct voltage. If wires or the box is loose, you could hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends hot or chilly air throughout your space, and a capacitor, which starts the motor. If either of these parts are fading, they will buzz when the furnace switches on.

3. Furnace Rattles

If your furnace is making a rattling noise, it may be related to something minor, like an unsecure screw, or something major, like a broken piece. In either case, we recommend shutting off your furnace and contacting our heating specialists at 601-736-7362 for support.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to tell you it requires some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn out or a bearing may need to be lubed. We know that maintenance frequently slips your mind, but our professionals can get your furnace operating quietly again rapidly.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You might also be aware of whistling while the furnace is working if a floor vent isn’t secure. If you’ve checked your vents but are still noticing noise, Watts Electric & AC can provide support. It’s important to get loose ductwork fixed quickly, as it can create comfort problems in your residence and drive up your heating expenses.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal noise typically means there’s a problem with your furnace’s blower. Switch off your furnace off right away and reach our professionals at 601-736-7362 for support.
