When your furnace is operating properly, it should give warm air without generating too much noise. While it’s common to catch your furnace making noise as it turns on, other disruptions are signaling your furnace needs immediate professional assistance.
Here are some of the most reported furnace noises and what they could be indicating. If your furnace is making an atypical noise, our friendly heating pros are here to fix the problem with the best furnace repair in Manassas, Virginia.
1. Furnace Making a Banging Noise
You could have an urgent situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a couple of problems. These involve gas accumulating in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system becomes filthy over the years, so that’s why it’s important to book routine furnace maintenance with Woody's Sudden Service. One of the tasks our technicians do during this appointment is clean your furnace’s burners. When this component gets dirty, you might hear your furnace making a loud rumbling noise if ignition takes more time. The resulting gas buildup may crack your furnace’s heat exchanger, where natural gas transforms into warm air. Any breaks in it can leak carbon monoxide, which is ordinarily emitted away from your home. This hazardous gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Woody's Sudden Service recommends turning it off and reaching us at 703-278-2036. Excessive natural gas in your furnace or a ruptured heat exchanger are critical troubles that should get fast service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide hot air across your house. If the ductwork wasn’t installed right or is getting dated, it can be noisy when your furnace is on. This might be the problem if your furnace makes a banging noise when it shuts off. Call Woody's Sudden Service at 703-278-2036 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 frequently means there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate on the right voltage. If wires or the box is loose, you could hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves warm or cooled air around your rooms, and a capacitor, which triggers the motor. If either of these parts are fading, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be the result of something small, like an unfastened screw, or something critical, like a broken part. In either case, we advise shutting your furnace off and calling our heating pros at 703-278-2036 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to get your attention it could use some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn down or a bearing may need to be lubricated. We realize that maintenance often slips your mind, but our technicians can get your furnace heating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You may also notice whistling while the furnace is operating if a floor vent is loose. If you’ve looked at your vents but are still sensing noise, Woody's Sudden Service can assist you. It’s critical to get loose ductwork fixed quickly, since it can make comfort troubles in your residence and inflate your heating bills.
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 typically means there’s a problem with your furnace’s blower. Turn off your furnace off instantly and contact our pros at 703-278-2036 for help.
