1. Furnace Making a Banging Noise

You may have an urgent issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be several problems. These include gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy over the years, so that’s why it’s essential to set routine furnace maintenance with Tri City Fuel & Heating Co., Inc.. One of the tasks our techs perform during this work is clean your furnace’s burners. When this part gets grimy, you could hear your furnace making a loud rumbling noise when ignition is delayed. The subsequent gas buildup can crack your furnace’s heat exchanger, where natural gas changes into warmth. Any cracks in it can leak carbon monoxide, which is ordinarily released away from your home. This dangerous gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Tri City Fuel & Heating Co., Inc. advises turning it off and calling us at 803-265-4208. Excessive natural gas in your furnace or a ruptured heat exchanger are critical troubles that necessitate prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move hot air across your home. If the ductwork wasn’t put in right or is getting dated, it can be noisy when your furnace runs. This might be the case if your furnace makes a banging noise when it shuts off. Get in touch with Tri City Fuel & Heating Co., Inc. 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 delay calling us. A buzzing sound often indicates an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run on the proper voltage. If wires or the box is loose, you may notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or cold air across your residence, and a capacitor, which triggers the motor. If either of these components are going out, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be due to something minor, like an unfastened screw, or something serious, like a broken piece. In either case, we advise shutting your furnace off and contacting our heating professionals at 803-265-4208 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, 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 out or a bearing could need to be greased. We are aware that maintenance often slips your mind, but our pros can get your furnace heating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You may also be aware of whistling while the furnace is operating if a floor vent isn’t secure. If you’ve looked at your vents but are still sensing whistling, Tri City Fuel & Heating Co., Inc. can provide support. It’s critical to get loose ductwork fixed quickly, as it can make comfort issues in your home and drive up your heating expenses.

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 usually means there’s trouble with your furnace’s blower. Switch off your furnace off promptly and contact our pros at 803-265-4208 for support.
