When your furnace is running correctly, it should deliver warmth without creating too much noise. While it’s normal to catch your furnace making noise as it begins running, other disruptions are signaling your furnace needs immediate professional assistance.
Here are some of the most common furnace noises and what they could be signaling. If your furnace is making a weird noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Covington, Georgia.
1. Furnace Makes Banging or Knocking Sounds
You might have a serious problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be a few problems. These include gas accumulating in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy as time passes, so that’s why it’s critical to book yearly furnace maintenance with Covington Air Systems. One of the things our pros complete during this appointment is clean your furnace’s burners. When this part gets dirty, you may hear your furnace making a loud rumbling noise after ignition takes more time. The resulting gas buildup may fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any cracks in it can emit carbon monoxide, which is regularly emitted away from your home. This dangerous gas can be deadly in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Covington Air Systems urges you to turn it off and calling us at (770) 462-5319. Too much natural gas in your furnace or a broken heat exchanger are dangerous problems that require fast service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to move hot air throughout your house. If the ductwork wasn’t installed right or is aging, it can make a lot of noise when your furnace runs. This might be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Covington Air Systems at (770) 462-5319 and we’ll determine the problem.
2. Furnace Makes a Buzzing Sound
If you hear your furnace making a buzzing noise, don’t wait to call 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 work on the right voltage. If wires or the box is loose, you might hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves hot or cooled air across your home, and a capacitor, which triggers the motor. If either of these pieces are fading, they will buzz when the furnace turns 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 major, like a broken component. In either case, we recommend shutting off your furnace and calling our heating specialists at (770) 462-5319 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to alert you it could use some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing could need to be lubricated. We realize that maintenance sometimes slips your mind, but our pros can get your furnace running quietly again rapidly.
5. Furnace Makes a Whistling Sound Like Air Escaping
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 isn’t secure. If you’ve checked your vents but are still noticing whistling, Covington Air Systems can provide support. It’s important to get loose ductwork repaired quickly, as it can create comfort issues in your house and inflate your energy expenses.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not a good sign if you notice 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 immediately and contact us at (770) 462-5319 for help.
