8 Furnace Noises You Should Never Ignore

Your furnace offers warmth and comfort to your home. While a faint noise is expected from your furnace when operating properly and a clicking sound is expected when your heating unit first turns on, it might be a sign of internal damage if you consistently hear oddly loud sounds, like whirring or banging, while it’s operating.

Your heating system may make strange noises for various reasons, including a malfunctioning fan motor, dirt buildup, a gas leak, and more. Therefore, it is wise to call the professionals at EASE for emergency furnace repair in Hemet, CA, rather than trying to fix the issue yourself when such problems happen. 

Eight Common Noises Made By A Faulty Heater

  • Loud Banging Noise

A loud pounding sound from your heater may indicate a problem. This noise typically signals a loose internal component, gas accumulating in your furnace, or a ductwork issue.

  • Buzzing Noise

An electrical issue, such as one with the transmitter, blower engine, or capacitor, is typically indicated by a buzzing sound. Your furnace also has an internal transformer to maintain the correct voltage. However, you could hear a low humming sound when this transformer has a problem, such as loose wires. Furthermore, your furnace may buzz due to unclean air filters or exterior evaporator coils.

  • Rattling Noise

If your heater makes a rattling noise, it could be due to something minor, such as a loose screw, or anything more severe, like a malfunctioning component.

  • Squealing Noise

High-pitched noises from your heater, like screeching, are an attempt to alert you to the need for repair. Additionally, squealing sounds coming from your heater might be a sign of various problems, such as worn-out fan belts, poor maintenance, or poorly greased bearings. So it is preferable to seek expert assistance when a furnace creates a screaming noise.

  • Whistling Noises

Your piping most likely leaks if you hear a whistling sound from your furnace. Additionally, you can hear whistling if you do not properly seal your vents. In case you’re still hearing noises after looking through your vents, a temperature control cap may help.

Getting loose ductwork fixed as soon as possible is essential, as it can cause comfort problems and raise energy costs.

  • Scraping Noises

There is most likely a problem with the furnace’s blower wheel that is causing the scraping noise. The blower wheel may be making scraping noises due to various circumstances. It’s likely that the wheel is loose and making noise by slamming into the blower housing.

  • Grinding Noises

The blower in your furnace is probably broken if you hear this metallic sound. Therefore, turn off your furnace while you wait for professionals to address the matter to prevent damage to your equipment.

  • A Thwapping Noise

Thwapping noises indicate that the blower is jammed with something. The noise is comparable to playing cards when attached to a bicycle wheel.
