Here are some of the most frequent furnace noises and what they might mean. If your furnace is making an odd noise, our friendly heating professionals are here to help with the best furnace repair in Ronkonkoma, NY.
1. Furnace Making a Banging Noise
You could have a critical situation on your hands if you’re hearing 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 range from gas building up in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system gets filthy over the years, so that’s why it’s important to schedule yearly furnace maintenance with Cool Power LLC . One of the tasks our professionals perform during this appointment is clean your furnace’s burners. When this component gets dirty, you may hear your furnace making a loud rumbling noise if ignition is delayed. The subsequent gas buildup might break your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can emit carbon monoxide, which is regularly vented outdoors. This hazardous gas can be lethal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Cool Power LLC urges you to turn it off and calling us at 631-246-4029. Too much natural gas in your furnace or a broken heat exchanger are dangerous problems that should get fast repairs.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move heated air around your residence. If the ductwork wasn’t installed properly or is aging, it can make a lot of noise when your furnace is heating. This might be the case if your furnace makes a banging noise when it shuts off. Contact Cool Power LLC at 631-246-4029 and we’ll pinpoint 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 typically indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to run on the proper voltage. If wires or the box is loose, you may detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves warm or chilly air across your rooms, and a capacitor, which starts the motor. If either of these components are fading, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be the result of something minor, like an unsecure screw, or something serious, like a broken part. In either case, we urge you to shut your furnace off and calling our heating specialists at 631-246-4029 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to get your attention it needs some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be dilapidated or a bearing could need to be greased. We know that maintenance frequently slips your mind, but our professionals can get your furnace heating quietly again quickly.
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 hear whistling while the furnace is working if a floor vent is loose. If you’ve looked at your vents but are still noticing whistling, Cool Power LLC can provide support. It’s critical to get loose ductwork fixed without delay, since it can make comfort problems in your home and drive up your utility bills.
6. Furnace Making a Grinding Noise
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal racket often means there’s trouble with your furnace’s blower. Shut down your furnace off promptly and reach our professionals at 631-246-4029 for support.
