1. Furnace Making a Banging Noise
You might have a serious situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be several problems. These range from gas accumulating in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system becomes dirty as time passes, so that’s why it’s critical to set annual furnace maintenance with Mayeuxs AC & Heating. One of the things our techs perform during this work is clean your furnace’s burners. When this component gets dirty, you could hear your furnace making a loud rumbling noise after ignition is delayed. The ensuing gas buildup can fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any fractures in it can leak carbon monoxide, which is ordinarily released away from your home. This hazardous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Mayeuxs AC & Heating recommends turning it off and contacting us at (985) 764-2426. Significant natural gas in your furnace or a fractured heat exchanger are hazardous problems that should get prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to provide heated air throughout your residence. If the ductwork wasn’t put in right or is aging, it can be loud when your furnace is on. This can be the issue if your furnace makes a banging noise when it shuts off. Call Mayeuxs AC & Heating at (985) 764-2426 and we’ll determine the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually 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 might detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves heated or chilly air around your space, and a capacitor, which triggers the motor. If either of these pieces are failing, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be the result of something minor, like a loose screw, or something serious, like a broken piece. In either case, we advise shutting your furnace off and calling our heating pros at (985) 764-2426 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to get your attention it requires some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn down or a bearing could need to be lubricated. We realize that maintenance frequently slips your mind, but our pros can get your furnace operating quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You may also notice whistling while the furnace is operating if a floor vent isn’t tight. If you’ve looked at your vents but are still hearing sound, Mayeuxs AC & Heating can provide support. It’s critical to get loose ductwork repaired without delay, since it can create comfort issues in your home and increase your energy expenses.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal noise frequently means there’s trouble with your furnace’s blower. Shut down your furnace off instantly and reach our pros at (985) 764-2426 for help.
