When your furnace is working like it should, it should provide heat without making too much sound. While it’s expected to notice your furnace making noise as it begins running, other sounds are signaling your furnace requires immediate professional support.
Here are some of the most reported furnace noises and what they could be signaling. If your furnace is making a strange noise, our friendly heating specialists are here to assist with the best furnace repair in Zelienople, Pennsylvania.
1. Furnace Makes Banging or Knocking Sounds
You may have a critical problem on your hands if you’re detecting 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 include gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy over the years, so that’s why it’s important to book seasonal furnace maintenance with Knoechel Heating. One of the things our techs complete during this appointment is clean your furnace’s burners. When this component gets grimy, you may hear your furnace making a loud rumbling noise if ignition is delayed. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any breaks in it can emit carbon monoxide, which is ordinarily vented outdoors. This toxic gas can be deadly in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Knoechel Heating urges you to turn it off and contacting us at 724-425-5852. Too much natural gas in your furnace or a cracked heat exchanger are hazardous problems that necessitate fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver hot air throughout your home. If the ductwork wasn’t installed properly or is getting old, it can make a lot of noise when your furnace runs. This may be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Knoechel Heating at 724-425-5852 and we’ll figure out the problem.
2. Furnace Buzzes Constantly
If you observe 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 uses an internal transformer to operate on the right voltage. If wires or the box needs to be tightened, you might hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends heated or cooled air across your space, and a capacitor, which triggers the motor. If either of these parts are failing, they will buzz when the furnace switches on.
3. Furnace Makes Rattling Sounds Like Something Is Loose
If your furnace is making a rattling noise, it may be due to something little, like an unfastened screw, or something critical, like a broken part. In either case, we advise shutting your furnace off and getting in touch with our heating professionals at 724-425-5852 for help.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to get your attention it requires some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing might need to be lubed. We realize that maintenance often slips your mind, but our technicians can get your furnace operating quietly again rapidly.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re detecting your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You may also notice whistling while the furnace is running if a floor vent isn’t tight. If you’ve looked at your vents but are still sensing noise, Knoechel Heating can help. It’s important to get loose ductwork taken care of fast, as it can create comfort troubles in your house and drive up your utility bills.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal racket often means there’s trouble with your furnace’s blower. Switch off your furnace off immediately and contact our professionals at 724-425-5852 for assistance.
