When your furnace is working like it should, it should provide warmth without generating too much disruption. While it’s expected to hear your furnace making noise as it begins running, other sounds are showing your furnace needs immediate professional assistance.

Here are some of the most frequent furnace noises and what they could be indicating. If your furnace is making an atypical noise, our friendly heating pros are here to fix the problem with the best furnace repair in West Columbia, South Carolina.

1. Furnace Making a Banging Noise

You might 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 can mean there could be several problems. These include gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty as time passes, so that’s why it’s essential to book routine furnace maintenance with Tri City Fuel & Heating. One of the jobs our professionals perform during this appointment is clean your furnace’s burners. When this piece gets grimy, you might hear your furnace making a loud rumbling noise when ignition takes longer than normal. The subsequent gas buildup may fracture your furnace’s heat exchanger, where natural gas changes into warmth. Any cracks in it can discharge carbon monoxide, which is ordinarily emitted outside. This toxic 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 calling us at 803-265-4208. Excessive natural gas in your furnace or a ruptured heat exchanger are hazardous issues that should get fast service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver warm air around your residence. If the ductwork wasn’t installed correctly or is aging, it can be noisy when your furnace is heating. This could be the issue 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 Buzzes Constantly

If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound often means there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to operate on the right voltage. If wires or the box needs to be tightened, you may notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves heated or cooled air throughout your home, and a capacitor, which triggers the motor. If either of these components are failing, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it could be due to something minor, like a loose screw, or something critical, 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 heating, it’s trying to get your attention it requires some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn down or a bearing may need to be greased. We realize that maintenance frequently slips your mind, but our technicians can get your furnace operating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You may also hear whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still noticing sound, Tri City Fuel & Heating can provide support. It’s important to get loose ductwork repaired quickly, since it can result in comfort issues in your home and drive up your gas bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal racket often means there’s a problem with your furnace’s blower. Switch off your furnace off promptly and contact our professionals at 803-265-4208 for support.
