When your furnace is working correctly, it should provide warmth without making too much disruption. While it’s common to hear your furnace making noise as it begins running, other sounds are indicating your furnace needs immediate professional support.
Here are some of the most common furnace noises and what they could be signaling. If your furnace is making an odd noise, our friendly heating pros are here to assist with the best furnace repair in Auburn, California.
1. Furnace Making a Banging Noise
You may have a serious issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be a few problems. These range from gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty over the years, so that’s why it’s essential to book routine furnace maintenance with Forster Heating. One of the things our pros complete during this work is clean your furnace’s burners. When this part gets grimy, you could hear your furnace making a loud rumbling noise when ignition takes more time. The ensuing gas buildup may fracture your furnace’s heat exchanger, where natural gas transforms into warmth. Any breaks in it can emit carbon monoxide, which is ordinarily vented away from your home. This dangerous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Forster Heating recommends turning it off and reaching us at 530-885-8081. Too much natural gas in your furnace or a broken heat exchanger are dangerous issues that should get immediate repairs.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to provide warm air throughout your house. If the ductwork wasn’t put in correctly or is aging, it can be loud when your furnace runs. This may be the case if your furnace makes a banging noise when it shuts off. Call Forster Heating at 530-885-8081 and we’ll figure out 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 usually means there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to operate on the proper voltage. If wires or the box needs to be tightened, you could notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes hot or cooled air across your house, and a capacitor, which turns on the motor. If either of these parts are fading, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it can be related to something little, like an unfastened screw, or something critical, like a broken piece. In either case, we urge you to shut your furnace off and getting in touch with our heating specialists at 530-885-8081 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 tell you it needs some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be lubricated. We know that maintenance frequently slips your mind, but our techs can get your furnace operating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You may also hear whistling while the furnace is operating if a floor vent isn’t secure. If you’ve looked at your vents but are still noticing whistling, Forster Heating can help. It’s critical to get loose ductwork fixed without delay, since it can create comfort issues in your house and drive up your utility expenses.
6. Furnace Making a Grinding Noise
It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal racket usually means there’s a problem with your furnace’s blower. Shut down your furnace off instantly and contact our professionals at 530-885-8081 for help.
