When your furnace is running correctly, it should provide warm air without generating too much sound. While it’s common to catch your furnace making noise as it starts up, other noises are signaling your furnace requires immediate professional assistance.
Here are some of the most frequent furnace noises and what they might be signaling. If your furnace is making an odd noise, our friendly heating specialists are here to assist with the best furnace repair in Morgantown, West Virginia.
1. Furnace Making a Banging Noise
You could have a serious situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a couple of problems. These involve gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty over the years, so that’s why it’s essential to set seasonal furnace maintenance with Mountain Air. One of the jobs our pros perform during this appointment is clean your furnace’s burners. When this component gets grimy, you may hear your furnace making a loud rumbling noise when ignition takes longer than normal. The following gas buildup can fracture your furnace’s heat exchanger, where natural gas turns into heat. Any cracks in it can emit carbon monoxide, which is normally emitted outdoors. This toxic gas can be lethal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Mountain Air advises turning it off and calling us at 304-413-1287. Significant natural gas in your furnace or a fractured heat exchanger are critical troubles that necessitate fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to provide heated air throughout your house. If the ductwork wasn’t designed correctly or is getting dated, it can make a lot of noise when your furnace is on. This can be the case if your furnace makes a banging noise when it shuts off. Call Mountain Air at 304-413-1287 and we’ll figure out 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 frequently indicates an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to run on the right voltage. If wires or the box is loose, you may notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves hot or cooled air across your home, and a capacitor, which starts the motor. If either of these components are going out, they will buzz when the furnace turns on.
3. Furnace Rattles
If your furnace is making a rattling noise, it can be the result of something small, like an unsecure screw, or something critical, like a broken component. In either case, we recommend shutting off your furnace and calling our heating specialists at 304-413-1287 for support.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to tell you it requires some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing could need to be greased. We know that maintenance frequently slips your mind, but our professionals can get your furnace running quietly again quickly.
5. Furnace Whistles
When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also notice whistling while the furnace is operating if a floor vent isn’t secure. If you’ve looked at your vents but are still sensing whistling, Mountain Air can provide support. It’s critical to get loose ductwork fixed fast, because it can make comfort troubles in your house and increase your heating costs.
6. Furnace Makes a Loud, Unpleasant 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 an issue with your furnace’s blower. Switch off your furnace off right away and contact our pros at 304-413-1287 for support.
