Here are some of the most frequent furnace noises and what they might be indicating. If your furnace is making an atypical noise, our friendly heating specialists are here to help with the best furnace repair in Carson City, Nevada.

1. Furnace Makes a Banging Sound

You may have an urgent situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be a few problems. These range from gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty over time, so that’s why it’s essential to set yearly furnace maintenance with Anderson Heating & A/C. One of the things our technicians do during this appointment is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise if ignition is delayed. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas turns into heat. Any breaks in it can leak carbon monoxide, which is normally vented away from your home. This toxic gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Anderson Heating & A/C urges you to turn it off and reaching us at 775-230-7628. Too much natural gas in your furnace or a cracked heat exchanger are serious troubles that necessitate prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide heated air across your house. If the ductwork wasn’t installed right or is aging, it can be noisy when your furnace is heating. This can be the case if your furnace makes a banging noise when it shuts off. Call Anderson Heating & A/C at 775-230-7628 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 often indicates an electrical issue, 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 is loose, you might detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves warm or cold air across your space, and a capacitor, which turns on the motor. If either of these pieces are going out, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be the result of something little, like an unfastened screw, or something serious, like a broken part. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at 775-230-7628 for help.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to get your attention it requires some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be greased. We realize that maintenance frequently slips your mind, but our professionals can get your furnace operating quietly again rapidly.

5. Furnace Whistles

When you’re noticing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You may also hear whistling while the furnace is running if a floor vent isn’t secure. If you’ve looked at your vents but are still hearing whistling, Anderson Heating & A/C can provide support. It’s important to get loose ductwork repaired fast, since it can result in comfort troubles in your home and drive up your heating expenses.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal noise frequently means there’s a problem with your furnace’s blower. Shut down your furnace off promptly and contact us at 775-230-7628 for support.
