When your furnace is working correctly, it should give heat without creating too much disruption. While it’s expected to catch your furnace making noise as it begins running, other noises are indicating your furnace should get immediate professional assistance.

Here are some of the most reported furnace noises and what they could be signaling. If your furnace is making an atypical noise, our friendly heating specialists are here to help with the best furnace repair in Paxinos, Pennsylvania.

1. Furnace Making a Banging Noise

You may have a critical situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be several problems. These involve gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy over the years, so that’s why it’s essential to schedule annual furnace maintenance with LTS Plumbing & Heating Inc.. One of the tasks our techs do during this appointment is clean your furnace’s burners. When this piece gets grimy, you could 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 turns into warm air. Any cracks in it can emit carbon monoxide, which is normally vented away from your home. This dangerous gas can be deadly 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. Excessive natural gas in your furnace or a fractured heat exchanger are dangerous troubles that necessitate fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move warm air around your residence. If the ductwork wasn’t designed correctly or is aging, it can be loud when your furnace is on. This can be the case if your furnace makes a banging noise when it shuts off. Call LTS Plumbing & Heating Inc. at 570-648-0748 and we’ll pinpoint 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 often means there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to work on the proper voltage. If wires or the box is loose, you could notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves warm or cooled air across your home, and a capacitor, which triggers the motor. If either of these pieces are failing, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be the result of something little, like an unsecure screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and contacting our heating pros at 570-648-0748 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to alert you it requires some TLC. If you’ve neglected furnace maintenance recently, belts could be worn down or a bearing may need to be lubricated. We realize that maintenance sometimes slips your mind, but our techs can get your furnace running quietly again fast.

5. Furnace Making a Whistling Noise

When you’re detecting 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 on if a floor vent isn’t secure. If you’ve examined your vents but are still sensing whistling, LTS Plumbing & Heating Inc. can assist you. It’s important to get loose ductwork repaired fast, since it can result in comfort problems in your house and drive up your energy bills.

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 sound frequently means there’s an issue with your furnace’s blower. Shut down your furnace off now and reach our professionals at 570-648-0748 for assistance.
