When your furnace is operating like it should, it should give heat without generating too much sound. While it’s expected to notice your furnace making noise as it starts up, other sounds are showing your furnace requires immediate professional assistance.
Here are some of the most common furnace noises and what they might mean. If your furnace is making an odd noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Reinholds, PA.
1. Furnace Making a Banging Noise
You could 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 might signal there could be a couple of problems. These range from gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy as time passes, so that’s why it’s critical to schedule seasonal furnace maintenance with County Line Mechanical LLC. One of the things our pros do during this service is clean your furnace’s burners. When this piece gets grimy, you might hear your furnace making a loud rumbling noise after ignition takes longer than normal. The following gas buildup can break your furnace’s heat exchanger, where natural gas turns into warm air. Any breaks in it can discharge carbon monoxide, which is regularly vented outside. This toxic gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, County Line Mechanical LLC urges you to turn it off and calling us at 717-216-0846. Significant natural gas in your furnace or a cracked heat exchanger are hazardous troubles that should get fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide hot air throughout your residence. If the ductwork wasn’t put in right or is getting dated, it can be noisy when your furnace is heating. This may be the case if your furnace makes a banging noise when it shuts off. Get in touch with County Line Mechanical LLC at 717-216-0846 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 indicates an electrical problem, 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 hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes hot or cooled air around your house, and a capacitor, which turns on the motor. If either of these parts are going out, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it might be the result of something minor, like an unsecure screw, or something major, like a broken part. In either case, we recommend shutting off your furnace and getting in touch with our heating pros at 717-216-0846 for support.
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 could use some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be lubed. We realize that maintenance often slips your mind, but our technicians can get your furnace operating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You may also be aware of whistling while the furnace is on if a floor vent isn’t secure. If you’ve checked your vents but are still sensing sound, County Line Mechanical LLC can provide support. It’s critical to get loose ductwork repaired quickly, as it can create comfort issues in your house and inflate your energy bills.
6. Furnace Making a Grinding Noise
It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal racket often means there’s a problem with your furnace’s blower. Switch off your furnace off promptly and contact our professionals at 717-216-0846 for support.
