Here are some of the most frequent furnace noises and what they could mean. If your furnace is making a strange noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Shamokin and Sunbury, Pennsylvania.
1. Furnace Makes Banging or Knocking Sounds
You may have a serious problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be a few problems. These include gas increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty over time, so that’s why it’s critical to schedule yearly furnace maintenance with LTS Plumbing & Heating Inc.. One of the things our pros do during this service is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise when ignition takes more time. The ensuing gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can discharge carbon monoxide, which is normally vented away from your home. This toxic gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, LTS Plumbing & Heating Inc. urges you to turn it off and contacting us at 570-648-0748. Too much natural gas in your furnace or a cracked heat exchanger are hazardous troubles that should get prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to provide warm air throughout your residence. If the ductwork wasn’t designed right or is aging, it can be loud when your furnace runs. This could be the problem if your furnace makes a banging noise when it shuts off. Call LTS Plumbing & Heating Inc. at 570-648-0748 and we’ll figure out the problem.
2. Furnace Makes a Buzzing Sound
If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically means there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to operate on the right voltage. If wires or the box isn’t tight enough, you may detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes heated or chilly air across your house, and a capacitor, which triggers the motor. If either of these parts are fading, 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 could be related to something minor, like an unsecure screw, or something major, like a broken piece. In either case, we recommend shutting off your furnace and getting in touch with our heating pros at 570-648-0748 for help.
4. Furnace Is Making a High-Pitched Squealing Sound
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to get your attention it requires some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be lubricated. We are aware that maintenance frequently slips your mind, but our technicians can get your furnace heating quietly again quickly.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You may also notice whistling while the furnace is operating if a floor vent isn’t tight. If you’ve looked at your vents but are still hearing noise, LTS Plumbing & Heating Inc. can help. It’s critical to get loose ductwork fixed quickly, since it can make comfort problems in your home and drive up your heating expenses.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal sound usually means there’s a problem with your furnace’s blower. Shut down your furnace off immediately and reach our professionals at 570-648-0748 for support.
