1. Furnace Making a Banging Noise
You may have a serious 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 couple of problems. These include gas building up in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty over time, so that’s why it’s critical to schedule seasonal furnace maintenance with Mayeuxs AC & Heating. One of the things our technicians do during this work is clean your furnace’s burners. When this piece gets dirty, you might hear your furnace making a loud rumbling noise if ignition takes longer than normal. The resulting 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 normally emitted outside. 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 broken heat exchanger are critical issues that require prompt attention.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver hot air around your home. If the ductwork wasn’t put in properly or is aging, it can be noisy when your furnace is on. This could be the problem 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 notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often indicates an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to work on the proper 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 uses a blower motor, which moves heated or chilly air around your residence, and a capacitor, which triggers the motor. If either of these parts are failing, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be related to something little, like an unfastened screw, or something major, like a broken component. In either case, we advise shutting your furnace off and calling our heating pros at (985) 764-2426 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to get your attention it needs some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be lubricated. We are aware that maintenance often slips your mind, but our professionals can get your furnace running quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You might also be aware of whistling while the furnace is running if a floor vent isn’t tight. If you’ve looked at your vents but are still sensing whistling, Mayeuxs AC & Heating can assist you. It’s essential to get loose ductwork fixed without delay, since it can make comfort troubles in your home and inflate your heating costs.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal sound usually means there’s a problem with your furnace’s blower. Shut down your furnace off immediately and call our professionals at (985) 764-2426 for help.
