When your furnace is operating like it should, it should deliver warmth without making too much disruption. While it’s normal to catch your furnace making noise as it starts up, other sounds are signaling your furnace requires immediate professional assistance.
Here are some of the most reported furnace noises and what they might be indicating. If your furnace is making an atypical noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Manassas, VA.
1. Furnace Making a Banging Noise
You may 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 mean there could be several problems. These range from gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty over time, so that’s why it’s important to set routine furnace maintenance with Woody's Sudden Service Inc. One of the things our pros do 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 is delayed. The subsequent gas buildup may fracture your furnace’s heat exchanger, where natural gas transforms into warm air. Any fractures in it can emit carbon monoxide, which is normally emitted outdoors. This dangerous gas can be lethal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Woody's Sudden Service Inc advises turning it off and reaching us at 703-278-2036. Significant natural gas in your furnace or a broken heat exchanger are critical issues that should get immediate attention.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver warm air throughout your house. If the ductwork wasn’t installed correctly or is getting old, it can be noisy when your furnace runs. This may be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Woody's Sudden Service Inc at 703-278-2036 and we’ll determine 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 often indicates an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to operate on the proper voltage. If wires or the box isn’t tight enough, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends warm or cooled air around your home, and a capacitor, which turns on the motor. If either of these parts 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 can be due to something minor, like an unsecure screw, or something major, like a broken part. In either case, we advise shutting your furnace off and getting in touch with our heating pros at 703-278-2036 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to get your attention it needs some TLC. If you’ve neglected furnace maintenance recently, belts could be dilapidated or a bearing may need to be lubed. We realize that maintenance frequently slips your mind, but our professionals can get your furnace heating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You could also notice whistling while the furnace is operating if a floor vent is loose. If you’ve examined your vents but are still hearing whistling, Woody's Sudden Service Inc can assist you. It’s important to get loose ductwork fixed without delay, since it can result in comfort issues in your home and drive up your energy costs.
6. Furnace Making a Grinding Noise
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal racket usually means there’s trouble with your furnace’s blower. Turn off your furnace off now and call our pros at 703-278-2036 for help.
