When your furnace is running correctly, it should deliver warmth without making too much noise. While it’s normal to notice your furnace making noise as it begins running, other noises are indicating your furnace requires immediate professional assistance.

Here are some of the most frequent furnace noises and what they might be signaling. If your furnace is making an odd noise, our friendly heating specialists are here to assist with the best furnace repair in West Columbia, South Carolina.

1. Furnace Making a Banging Noise

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

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty as time passes, so that’s why it’s critical to set annual furnace maintenance with Tri City Fuel & Heating. One of the jobs our pros do during this appointment is clean your furnace’s burners. When this piece gets grubby, you may hear your furnace making a loud rumbling noise if ignition takes longer than normal. The following gas buildup might crack your furnace’s heat exchanger, where natural gas changes into warm air. Any fractures in it can leak carbon monoxide, which is regularly emitted away from your home. This hazardous gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Tri City Fuel & Heating advises turning it off and contacting us at 803-265-4208. Too much natural gas in your furnace or a fractured heat exchanger are hazardous problems that require fast service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move heated air around your residence. If the ductwork wasn’t put in properly or is aging, it can be noisy when your furnace is heating. This could be the problem if your furnace makes a banging noise when it shuts off. Call Tri City Fuel & Heating at 803-265-4208 and we’ll determine the problem.

2. Furnace Buzzes Constantly

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 run on the correct voltage. If wires or the box is loose, you may notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes heated or cold air throughout your house, and a capacitor, which starts the motor. If either of these parts are failing, 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 small, like an unfastened screw, or something critical, like a broken component. In either case, we advise shutting your furnace off and calling our heating professionals at 803-265-4208 for help.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to get your attention it could use some TLC. If you’ve skipped furnace maintenance recently, belts could be worn out or a bearing might 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 due to an air leak in your ductwork. You could also be aware of whistling while the furnace is on if a floor vent is loose. If you’ve looked at your vents but are still sensing whistling, Tri City Fuel & Heating can assist you. It’s important to get loose ductwork repaired without delay, since it can result in comfort issues in your residence and drive up your heating expenses.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal sound frequently means there’s an issue with your furnace’s blower. Switch off your furnace off now and call us at 803-265-4208 for assistance.
