When your furnace is running like it should, it should provide 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 needs immediate professional help.
Here are some of the most common furnace noises and what they can mean. If your furnace is making an atypical noise, our friendly heating specialists are here to help with the best furnace repair in West Columbia, SC.
1. Furnace Making a Banging Noise
You may have a critical 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 involve gas building up in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty over time, so that’s why it’s essential to book routine furnace maintenance with Tri City Fuel & Heating Co., Inc.. One of the things our techs perform during this service is clean your furnace’s burners. When this part gets dirty, you could hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup can break your furnace’s heat exchanger, where natural gas changes into warmth. Any breaks in it can leak carbon monoxide, which is regularly emitted away from your home. 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 Co., Inc. advises turning it off and calling us at 803-265-4208. Too much natural gas in your furnace or a ruptured heat exchanger are dangerous troubles that should get fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to move heated air across your house. If the ductwork wasn’t put in right or is aging, it can be noisy when your furnace is heating. This may be the problem 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 figure out the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to operate on the correct voltage. If wires or the box is loose, you may detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes warm or cold air across your house, and a capacitor, which starts 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 small, like a loose screw, or something major, like a broken part. In either case, we recommend shutting off your furnace and contacting our heating professionals at 803-265-4208 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to alert you it could use some TLC. If you’ve neglected furnace maintenance recently, belts could be worn down or a bearing could need to be greased. We realize that maintenance frequently slips your mind, but our professionals can get your furnace running quietly again fast.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You might also hear whistling while the furnace is on if a floor vent is loose. If you’ve looked at your vents but are still sensing noise, Tri City Fuel & Heating Co., Inc. can provide support. It’s essential to get loose ductwork repaired fast, because it can result in comfort troubles in your home and drive up your gas costs.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal racket typically means there’s a problem with your furnace’s blower. Turn off your furnace off right away and reach our professionals at 803-265-4208 for support.
