When your furnace is operating like it should, it should provide warmth without generating too much disruption. While it’s expected to hear your furnace making noise as it turns on, other sounds are showing your furnace needs immediate professional assistance.
Here are some of the most reported furnace noises and what they can 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 Belton, Missouri.
1. Furnace Makes a Banging Sound
You may have a serious issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be several problems. These involve gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty over the years, so that’s why it’s important to set annual furnace maintenance with Myers Furnace Company. One of the jobs our techs complete during this service is clean your furnace’s burners. When this piece gets grimy, you could hear your furnace making a loud rumbling noise when ignition takes more time. The ensuing gas buildup may fracture your furnace’s heat exchanger, where natural gas transforms into warm air. Any fractures in it can discharge carbon monoxide, which is ordinarily released away from your home. 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 recommends turning it off and contacting us at 816-249-1619. Too much natural gas in your furnace or a cracked heat exchanger are critical issues that require fast service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver hot air across your house. If the ductwork wasn’t designed properly or is getting old, it can be noisy when your furnace is on. This may be the case if your furnace makes a banging noise when it shuts off. Contact Myers Furnace Company at 816-249-1619 and we’ll pinpoint 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 frequently means there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to operate on the proper voltage. If wires or the box isn’t tight enough, you could hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or chilly air across your home, and a capacitor, which starts the motor. If either of these components are failing, they will buzz when the furnace switches on.
3. Furnace Makes Rattling Sounds Like Something Is Loose
If your furnace is making a rattling noise, it can be the result of something minor, like an unfastened screw, or something critical, like a broken piece. In either case, we advise shutting your furnace off and contacting our heating professionals at 816-249-1619 for support.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to alert you it requires some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn down or a bearing could need to be greased. We know that maintenance frequently slips your mind, but our professionals can get your furnace heating quietly again quickly.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re hearing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You might also hear whistling while the furnace is operating if a floor vent isn’t tight. If you’ve checked your vents but are still noticing whistling, Myers Furnace Company can assist you. It’s important to get loose ductwork repaired without delay, as it can result in comfort problems in your residence and drive up your heating bills.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal noise often means there’s an issue with your furnace’s blower. Turn off your furnace off right away and call our pros at 816-249-1619 for assistance.
