When your furnace is running like it should, it should provide warm air without creating too much disruption. While it’s normal to hear your furnace making noise as it begins running, other noises are showing your furnace should get immediate professional help.

1. Furnace Making a Banging Noise

You may have a critical situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be a couple of problems. These include gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty as time passes, so that’s why it’s important to book routine furnace maintenance with LTS Plumbing & Heating Inc.. One of the things our professionals do during this service is clean your furnace’s burners. When this piece gets grubby, you could hear your furnace making a loud rumbling noise when ignition is delayed. The resulting gas buildup may fracture your furnace’s heat exchanger, where natural gas transforms into warmth. Any fractures in it can leak carbon monoxide, which is ordinarily vented outdoors. This hazardous gas can be deadly 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. Significant natural gas in your furnace or a cracked heat exchanger are dangerous problems that necessitate immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide hot air around your house. If the ductwork wasn’t installed properly or is getting old, it can make a lot of noise when your furnace is on. This can be the problem if your furnace makes a banging noise when it shuts off. Get in touch with LTS Plumbing & Heating Inc. at 570-648-0748 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound typically is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to work on the proper voltage. If wires or the box isn’t tight enough, you could notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes heated or cold air across your rooms, and a capacitor, which starts the motor. If either of these components are fading, they will buzz when the furnace turns on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it could be related to something little, like an unfastened screw, or something serious, like a broken piece. In either case, we advise shutting your furnace off and getting in touch with our heating professionals 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 attempting to get your attention it needs some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing may need to be lubed. We realize that maintenance frequently slips your mind, but our techs can get your furnace operating quietly again quickly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re detecting your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You could also hear whistling while the furnace is working if a floor vent is loose. If you’ve looked at your vents but are still hearing noise, LTS Plumbing & Heating Inc. can help. It’s essential to get loose ductwork fixed fast, as it can create comfort troubles in your residence and drive up your energy bills.
