When your furnace is running properly, it should deliver heat without generating too much sound. While it’s expected to hear your furnace making noise as it begins running, other sounds are indicating your furnace should get immediate professional assistance.

Here are some of the most common furnace noises and what they can be signaling. If your furnace is making an atypical noise, our friendly heating pros are here to assist with the best furnace repair in Carson City, Nevada.

1. Furnace Making a Banging Noise

You might 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 can indicate there could be a few problems. These involve gas increasing in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty over time, so that’s why it’s critical to set seasonal furnace maintenance with Anderson Heating & A/C. One of the tasks our professionals perform during this work is clean your furnace’s burners. When this part gets grubby, you may hear your furnace making a loud rumbling noise when ignition is delayed. The ensuing gas buildup might break your furnace’s heat exchanger, where natural gas changes into warm air. Any fractures in it can leak carbon monoxide, which is normally vented away from your home. This dangerous gas can be lethal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Anderson Heating & A/C recommends turning it off and contacting us at 775-854-9700. Significant natural gas in your furnace or a ruptured heat exchanger are serious problems that require fast service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver heated air around your residence. If the ductwork wasn’t designed properly or is getting dated, it can be loud when your furnace runs. This can be the problem if your furnace makes a banging noise when it shuts off. Contact Anderson Heating & A/C at 775-854-9700 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you observe 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 run on the right voltage. If wires or the box needs to be tightened, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves hot or cold air across your rooms, and a capacitor, which triggers the motor. If either of these parts are fading, they will buzz when the furnace starts.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it may be due to something small, like an unsecure screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and calling our heating professionals at 775-854-9700 for support.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to get your attention it needs some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn out or a bearing might need to be lubed. We are aware that maintenance often slips your mind, but our techs can get your furnace heating quietly again fast.

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You could also be aware of whistling while the furnace is working if a floor vent isn’t tight. If you’ve checked your vents but are still sensing noise, Anderson Heating & A/C can assist you. It’s important to get loose ductwork taken care of fast, as it can result in comfort problems in your house and drive up your gas expenses.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal sound usually means there’s an issue with your furnace’s blower. Turn off your furnace off immediately and contact our pros at 775-854-9700 for support.
