When your furnace is working properly, it should give heat without creating too much noise. While it’s expected to notice your furnace making noise as it begins running, other sounds are showing your furnace needs immediate professional support.

Here are some of the most frequent furnace noises and what they might be indicating. If your furnace is making an odd noise, our friendly heating pros are here to assist with the best furnace repair in Belton, Missouri.

1. Furnace Makes a Banging Sound

You might have a critical problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a couple of problems. These involve gas increasing in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty over the years, so that’s why it’s essential to set annual furnace maintenance with Myers Furnace Company. One of the tasks our technicians perform during this service is clean your furnace’s burners. When this piece gets dirty, you could hear your furnace making a loud rumbling noise when ignition takes more time. The ensuing gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into warmth. Any cracks in it can leak carbon monoxide, which is ordinarily emitted outdoors. This toxic gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Myers Furnace Company advises turning it off and calling us at 816-249-1619. Significant natural gas in your furnace or a ruptured heat exchanger are critical troubles that require fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver hot air across your residence. If the ductwork wasn’t put in right or is getting dated, it can make a lot of noise when your furnace is on. This can be the issue if your furnace makes a banging noise when it shuts off. Contact Myers Furnace Company at 816-249-1619 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often means there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to run on the correct voltage. If wires or the box needs to be tightened, you could detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes heated or cold air around your house, and a capacitor, which starts the motor. If either of these pieces are fading, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be the result of something minor, like a loose screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and contacting our heating specialists at 816-249-1619 for support.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to alert you it requires some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out 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 Makes a Whistling Sound Like Air Escaping

When you’re detecting your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You could also notice whistling while the furnace is working if a floor vent is loose. If you’ve examined your vents but are still sensing sound, Myers Furnace Company can help. It’s essential to get loose ductwork taken care of without delay, because it can result in comfort problems in your residence and drive up your heating costs.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal sound typically means there’s trouble with your furnace’s blower. Turn off your furnace off immediately and contact our professionals at 816-249-1619 for help.
