When your furnace is running like it should, it should provide warmth without creating too much noise. While it’s common to catch your furnace making noise as it starts up, other disruptions are showing your furnace requires immediate professional help.
Here are some of the most reported furnace noises and what they might be signaling. If your furnace is making an atypical noise, our friendly heating pros are here to assist with the best furnace repair in Rapid City, South Dakota.
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 may indicate there could be a couple of problems. These range from gas building up in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy over the years, so that’s why it’s critical to book yearly furnace maintenance with Street Heating and Cooling. One of the tasks our professionals do during this appointment is clean your furnace’s burners. When this part gets grubby, you might hear your furnace making a loud rumbling noise when ignition takes longer than normal. The following gas buildup may fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any cracks in it can leak carbon monoxide, which is ordinarily vented away from your home. This hazardous gas can be lethal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Street Heating and Cooling recommends turning it off and calling us at 605-206-3915. Too much natural gas in your furnace or a cracked heat exchanger are hazardous troubles that require prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver warm air throughout your home. If the ductwork wasn’t installed right or is getting dated, it can make a lot of noise when your furnace is heating. This may be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Street Heating and Cooling at 605-206-3915 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound often is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the right voltage. If wires or the box is loose, you may notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes heated or cold air around your space, and a capacitor, which starts the motor. If either of these components are going out, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be the result of something minor, like a loose screw, or something major, like a broken part. In either case, we urge you to shut your furnace off and contacting our heating specialists at 605-206-3915 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 alert you it needs some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be greased. We know that maintenance often slips your mind, but our pros 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 typically because of an air leak in your ductwork. You could also hear whistling while the furnace is working if a floor vent isn’t tight. If you’ve looked at your vents but are still noticing sound, Street Heating and Cooling can provide support. It’s critical to get loose ductwork taken care of without delay, as it can result in comfort problems in your house and increase your energy expenses.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal racket usually means there’s an issue with your furnace’s blower. Switch off your furnace off instantly and reach our professionals at 605-206-3915 for support.
