When your furnace is operating like it should, it should give heat without generating too much disruption. While it’s normal to hear your furnace making noise as it starts up, other noises are signaling your furnace needs immediate professional help.
Here are some of the most common furnace noises and what they can be signaling. If your furnace is making an atypical noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Paxinos, PA.
1. Furnace Making a Banging Noise
You could have a serious problem on your hands if you’re noticing 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 gets grimy over time, so that’s why it’s essential to book yearly furnace maintenance with LTS Plumbing & Heating Inc.. One of the jobs our techs complete during this work is clean your furnace’s burners. When this piece gets grubby, you might hear your furnace making a loud rumbling noise when ignition is delayed. The subsequent gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can discharge carbon monoxide, which is regularly vented outdoors. This dangerous gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, LTS Plumbing & Heating Inc. advises turning it off and reaching us at 570-648-0748. Too much natural gas in your furnace or a broken heat exchanger are dangerous issues that necessitate fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide heated air across your residence. If the ductwork wasn’t designed right or is getting dated, it can be noisy when your furnace runs. This could be the issue 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 Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually means there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to work on the correct voltage. If wires or the box needs to be tightened, you might notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes warm or chilly air across your home, and a capacitor, which triggers the motor. If either of these parts are going out, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be related to something little, like a loose screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and getting in touch with our heating specialists at 570-648-0748 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting 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 could need to be greased. We realize that maintenance frequently slips your mind, but our professionals can get your furnace operating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You may also be aware of whistling while the furnace is operating if a floor vent isn’t tight. If you’ve checked your vents but are still sensing whistling, LTS Plumbing & Heating Inc. can provide support. It’s important to get loose ductwork taken care of fast, since it can make comfort troubles in your house and increase your heating costs.
6. Furnace Making a Grinding Noise
It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal racket typically means there’s trouble with your furnace’s blower. Turn off your furnace off immediately and call us at 570-648-0748 for assistance.
