1. Furnace Making a Banging Noise
You may have a serious situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a couple of problems. These include gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system becomes dirty as time passes, so that’s why it’s essential to book seasonal furnace maintenance with Dave's Diversified Services. One of the jobs our professionals complete during this service is clean your furnace’s burners. When this piece gets dirty, you might hear your furnace making a loud rumbling noise after ignition takes more time. The resulting gas buildup may crack your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can discharge carbon monoxide, which is normally released away from your home. This hazardous gas can be fatal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Dave's Diversified Services urges you to turn it off and calling us at 540-636-3396. Excessive natural gas in your furnace or a ruptured heat exchanger are critical troubles that should get prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move warm air throughout your house. If the ductwork wasn’t designed properly or is getting old, it can be loud when your furnace is on. This might be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Dave's Diversified Services at 540-636-3396 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound often is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to run on the correct voltage. If wires or the box isn’t tight enough, you could detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves heated or chilly air around your space, and a capacitor, which turns on the motor. If either of these pieces are failing, they will buzz when the furnace starts.
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 component. In either case, we urge you to shut your furnace off and getting in touch with our heating professionals at 540-636-3396 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to get your attention it requires some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing might need to be greased. We realize that maintenance often slips your mind, but our technicians can get your furnace running quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent isn’t secure. If you’ve looked at your vents but are still noticing noise, Dave's Diversified Services can provide support. It’s critical to get loose ductwork taken care of quickly, since it can result in comfort troubles in your residence and drive up your utility 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 noise often means there’s a problem with your furnace’s blower. Switch off your furnace off right away and call our professionals at 540-636-3396 for assistance.
