1. Furnace Makes Banging or Knocking Sounds

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

Banging Sounds Coming from Your Furnace

Your heating system gets filthy over time, so that’s why it’s critical to book annual furnace maintenance with Anderson Heating & A/C. One of the jobs our pros complete during this appointment is clean your furnace’s burners. When this component gets grimy, you could hear your furnace making a loud rumbling noise after ignition is delayed. The following gas buildup might fracture your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can discharge carbon monoxide, which is ordinarily emitted away from your home. This hazardous gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Anderson Heating & A/C recommends turning it off and calling us at 775-230-7628. Significant natural gas in your furnace or a broken heat exchanger are dangerous problems that should get prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide hot air across your residence. If the ductwork wasn’t installed right or is getting old, it can be loud when your furnace is heating. This might be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Anderson Heating & A/C at 775-230-7628 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound typically indicates an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run on the right voltage. If wires or the box isn’t tight enough, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves hot or cooled air throughout your rooms, and a capacitor, which starts the motor. If either of these components are fading, they will buzz when the furnace turns on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it can be the result of something small, like an unsecure screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating pros at 775-230-7628 for support.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to get your attention it needs some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be lubed. We are aware that maintenance frequently slips your mind, but our technicians can get your furnace heating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re hearing your furnace making a whistling noise, it’s likely because 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 secure. If you’ve examined your vents but are still hearing noise, Anderson Heating & A/C can provide support. It’s critical to get loose ductwork fixed without delay, because it can make comfort problems in your home and inflate your heating expenses.

6. Furnace Makes Noise that Sounds Like Scraping Metal
