1. Furnace Making a Banging Noise
You might have a serious problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be several problems. These range from gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets grimy as time passes, so that’s why it’s important to set routine furnace maintenance with Jack's Heating, Cooling, Stoves & Fireplaces. One of the jobs our pros do during this appointment is clean your furnace’s burners. When this piece gets grimy, you might hear your furnace making a loud rumbling noise when ignition is delayed. The following gas buildup can crack your furnace’s heat exchanger, where natural gas transforms into warmth. Any fractures in it can discharge carbon monoxide, which is ordinarily released outside. This toxic gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Jack's Heating, Cooling, Stoves & Fireplaces urges you to turn it off and contacting us at 308-762-1613. Too much natural gas in your furnace or a cracked heat exchanger are hazardous troubles that necessitate fast service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move heated air throughout your home. If the ductwork wasn’t designed right or is aging, it can make a lot of noise when your furnace runs. This can be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Jack's Heating, Cooling, Stoves & Fireplaces at 308-762-1613 and we’ll pinpoint 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 frequently is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate on the right voltage. If wires or the box needs to be tightened, you might hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves warm or chilly air across your space, and a capacitor, which starts the motor. If either of these components are failing, they will buzz when the furnace turns on.
3. Furnace Rattles
If your furnace is making a rattling noise, it could be due to something small, like an unfastened 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 308-762-1613 for help.
4. Furnace Is Making a High-Pitched Squealing Sound
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to tell you it could use some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn down or a bearing may need to be lubricated. We realize that maintenance frequently slips your mind, but our technicians can get your furnace heating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You might also notice whistling while the furnace is operating if a floor vent isn’t tight. If you’ve checked your vents but are still hearing sound, Jack's Heating, Cooling, Stoves & Fireplaces can provide support. It’s essential to get loose ductwork repaired without delay, because it can result in comfort problems in your residence and increase your heating bills.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal racket frequently means there’s a problem with your furnace’s blower. Shut down your furnace off right away and reach our pros at 308-762-1613 for support.
