When your furnace is running properly, it should deliver warmth without creating too much sound. While it’s common to catch your furnace making noise as it begins running, other disruptions are showing your furnace needs immediate professional support.
Here are some of the most frequent furnace noises and what they can be indicating. If your furnace is making an atypical noise, our friendly heating professionals are here to assist with the best furnace repair in Lafayette, Louisiana.
1. Furnace Making a Banging Noise
You may have an urgent situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a couple of problems. These range from gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy over time, so that’s why it’s essential to schedule routine furnace maintenance with AC Sales. One of the tasks our professionals perform during this appointment is clean your furnace’s burners. When this component gets grimy, you could hear your furnace making a loud rumbling noise after ignition takes more time. The following gas buildup can break your furnace’s heat exchanger, where natural gas transforms into warmth. Any breaks in it can emit carbon monoxide, which is ordinarily vented away from your home. This hazardous gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, AC Sales urges you to turn it off and calling us at (337) 234-2345. Significant natural gas in your furnace or a fractured heat exchanger are serious problems that require prompt attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move heated air throughout your residence. If the ductwork wasn’t put in properly or is getting old, it can make a lot of noise when your furnace is heating. This can be the issue if your furnace makes a banging noise when it shuts off. Contact AC Sales at (337) 234-2345 and we’ll determine the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound frequently means there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to run on the proper voltage. If wires or the box needs to be tightened, you could notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves heated or cold air around your space, and a capacitor, which starts the motor. If either of these pieces are failing, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be due to something small, like a loose screw, or something critical, like a broken component. In either case, we recommend shutting off your furnace and contacting our heating specialists at (337) 234-2345 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to alert you it needs some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn out or a bearing may need to be greased. We are aware that maintenance sometimes slips your mind, but our professionals can get your furnace operating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You may also notice whistling while the furnace is running if a floor vent is loose. If you’ve looked at your vents but are still noticing whistling, AC Sales can provide support. It’s essential to get loose ductwork taken care of fast, as it can result in comfort troubles in your residence and drive up your energy expenses.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal racket usually means there’s an issue with your furnace’s blower. Shut down your furnace off right away and call our pros at (337) 234-2345 for support.
