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 can mean 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 dirty as time passes, so that’s why it’s essential to book yearly furnace maintenance with Bell Air Conditioning Inc. One of the things our technicians complete during this service is clean your furnace’s burners. When this piece gets grubby, you could hear your furnace making a loud rumbling noise when ignition is delayed. The subsequent gas buildup can break your furnace’s heat exchanger, where natural gas changes into warm air. Any breaks in it can discharge carbon monoxide, which is normally emitted away from your home. This hazardous gas can be fatal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Bell Air Conditioning Inc urges you to turn it off and contacting us at 254-307-9572. Significant natural gas in your furnace or a cracked heat exchanger are hazardous troubles that should get immediate attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move warm air around your home. If the ductwork wasn’t put in properly or is getting dated, 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. Get in touch with Bell Air Conditioning Inc at 254-307-9572 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually means there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the correct voltage. If wires or the box isn’t tight enough, you may detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes hot or chilly air throughout your residence, and a capacitor, which starts the motor. If either of these parts are going out, they will buzz when the furnace turns on.
3. Furnace Rattles
If your furnace is making a rattling noise, it can be due to something minor, like a loose screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at 254-307-9572 for assistance.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to get your attention it needs some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing may need to be lubricated. We know that maintenance often slips your mind, but our technicians can get your furnace heating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You could also hear whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still sensing sound, Bell Air Conditioning Inc can assist you. It’s essential to get loose ductwork taken care of quickly, because it can create comfort troubles in your residence and drive up your energy expenses.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal racket usually means there’s an issue with your furnace’s blower. Switch off your furnace off instantly and call our pros at 254-307-9572 for help.
