When your furnace is operating properly, it should provide warmth without creating too much noise. While it’s expected to hear your furnace making noise as it starts up, other disruptions are showing your furnace requires immediate professional assistance.

Here are some of the most frequent furnace noises and what they might be indicating. If your furnace is making a weird noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Auburn and Opelika, Alabama.

1. Furnace Makes a Banging Sound

You may have a critical problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be several problems. These include gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy over the years, so that’s why it’s important to book routine furnace maintenance with Farnell Mechanical, Inc.. One of the things our technicians perform during this appointment is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise after ignition takes longer than normal. The subsequent gas buildup may fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can discharge carbon monoxide, which is ordinarily emitted outside. This hazardous gas can be lethal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Farnell Mechanical, Inc. advises turning it off and contacting us at 334-524-2458. Too much natural gas in your furnace or a fractured heat exchanger are critical problems that require immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide hot air around your home. If the ductwork wasn’t put in properly or is getting old, it can make a lot of noise when your furnace is on. This may be the case if your furnace makes a banging noise when it shuts off. Get in touch with Farnell Mechanical, Inc. at 334-524-2458 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually 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 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 throughout your house, and a capacitor, which triggers the motor. If either of these pieces are going out, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be the result of something minor, like an unsecure screw, or something critical, like a broken piece. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at 334-524-2458 for support.

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 attempting to tell you it needs some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be lubed. We are aware that maintenance frequently slips your mind, but our techs can get your furnace heating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re hearing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You could also be aware of whistling while the furnace is operating if a floor vent isn’t tight. If you’ve checked your vents but are still sensing whistling, Farnell Mechanical, Inc. can provide support. It’s important to get loose ductwork fixed without delay, as it can make comfort problems in your home and increase your heating expenses.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal noise frequently means there’s a problem with your furnace’s blower. Turn off your furnace off right away and contact us at 334-524-2458 for support.
