When your furnace is operating properly, it should deliver heat without making too much sound. While it’s common to hear your furnace making noise as it turns on, other sounds are showing your furnace requires immediate professional support.

Here are some of the most common furnace noises and what they can be signaling. If your furnace is making a weird noise, our friendly heating pros are here to help with the best furnace repair in West Columbia, South Carolina.

1. Furnace Making a Banging Noise

You could have a serious issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be several problems. These include gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy over time, so that’s why it’s important to schedule routine furnace maintenance with Tri City Fuel & Heating. One of the things our professionals complete during this service is clean your furnace’s burners. When this part gets grubby, you may hear your furnace making a loud rumbling noise when ignition is delayed. The ensuing gas buildup can break your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can discharge carbon monoxide, which is regularly released outside. This dangerous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Tri City Fuel & Heating recommends turning it off and reaching us at 803-265-4208. Significant natural gas in your furnace or a ruptured heat exchanger are dangerous troubles that require immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move warm air across your home. If the ductwork wasn’t installed properly or is aging, it can be loud when your furnace is heating. This might be the case if your furnace makes a banging noise when it shuts off. Get in touch with Tri City Fuel & Heating at 803-265-4208 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 issue, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to operate on the correct voltage. If wires or the box isn’t tight enough, you may hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes hot or chilly air throughout your residence, and a capacitor, which triggers the motor. If either of these components are fading, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be due to something little, like an unfastened screw, or something serious, like a broken part. In either case, we recommend shutting off your furnace and calling our heating professionals at 803-265-4208 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to alert you it requires some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn down or a bearing could need to be lubricated. We are aware that maintenance sometimes slips your mind, but our techs can get your furnace heating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You could also be aware of whistling while the furnace is operating if a floor vent is loose. If you’ve checked your vents but are still hearing noise, Tri City Fuel & Heating can assist you. It’s important to get loose ductwork repaired without delay, since it can make comfort problems in your house and inflate your heating bills.

6. Furnace Making a Grinding Noise

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal sound typically means there’s a problem with your furnace’s blower. Shut down your furnace off immediately and contact our pros at 803-265-4208 for help.
