When your furnace is running properly, it should deliver warmth without generating too much disruption. While it’s normal to catch your furnace making noise as it begins running, other sounds are signaling your furnace should get immediate professional help.

Here are some of the most frequent furnace noises and what they can be indicating. If your furnace is making a weird noise, our friendly heating pros are here to assist with the best furnace repair in Lodi, California.

• Furnace Makes Banging or Knocking Sounds: You could have a critical problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a few problems. These include gas building up in your furnace or a ductwork problem.
  1. Banging Sounds Coming from Your Furnace: Your heating system turns dirty over the years, so that’s why it’s important to schedule yearly furnace maintenance with Tokay Heating & Air. One of the jobs our pros do during this service is clean your furnace’s burners. When this piece gets grubby, you might hear your furnace making a loud rumbling noise when ignition takes longer than normal. The ensuing gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can emit carbon monoxide, which is regularly emitted outside. This dangerous gas can be fatal in large concentrations.
     If you’re aware of banging or knocking sounds coming from your furnace, Tokay Heating & Air recommends turning it off and reaching us at (209) 257-3156. Significant natural gas in your furnace or a cracked heat exchanger are hazardous problems that require prompt attention.
  2. Banging Sounds Coming from Your Ductwork: Your furnace works with ductwork to deliver hot air around your home. If the ductwork wasn’t put in right or is getting old, it can be loud when your furnace is heating. This could be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Tokay Heating & Air at (209) 257-3156 and we’ll pinpoint the problem.
• Furnace Making a Buzzing Noise: If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually indicates an electrical situation, like with its transformer, blower motor or capacitor.
  Your furnace relies on an internal transformer to work on the proper voltage. If wires or the box is loose, you may detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends warm or chilly air around your space, and a capacitor, which starts the motor. If either of these pieces are fading, they will buzz when the furnace switches on.
• Furnace Makes Rattling Sounds Like Something Is Loose: If your furnace is making a rattling noise, it could be related to something small, like a loose screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and contacting our heating pros at (209) 257-3156 for assistance.
• Furnace Is Making a High-Pitched Squealing Sound: If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to get your attention it needs some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn out or a bearing may need to be lubed. We know that maintenance often slips your mind, but our pros can get your furnace heating quietly again rapidly.
• Furnace Making a Whistling Noise: When you’re detecting your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You could also hear whistling while the furnace is on if a floor vent isn’t secure. If you’ve examined your vents but are still noticing sound, Tokay Heating & Air can provide support. It’s critical to get loose ductwork fixed without delay, as it can result in comfort troubles in your residence and drive up your energy expenses.
• Furnace Making a Grinding Noise: It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal noise usually means there’s an issue with your furnace’s blower. Switch off your furnace off promptly and call us at (209) 257-3156 for help.
