10 HVAC Noises You Shouldn’t Ignore
Your HVAC system works hard to keep your home comfortable year-round, but sometimes it can communicate its struggles through a variety of sounds. Ignoring these noises can lead to damage and expensive repairs down the road. Here are 10 HVAC noises you shouldn’t ignore.
- Banging or clanking: This could indicate leaky ductwork, debris caught in the system, or a damaged blower motor.
- Hissing or whistling: A refrigerant leak is usually marked by hissing or whistling sounds, and refrigerant leaks can reduce system efficiency and cause costly repairs.
- Popping or gurgling: Clogged condensate drain lines or low refrigerant levels might cause your system to make popping or gurgling noises.
- Screeching or grinding: Screeching or grinding noises could be a sign of worn belts or failing bearings in the motor or compressor.
- Loud booms: Loud booming or crashing could be a serious issue, such as a cracked heat exchanger or trapped gas in your system. Shut off your system and call us immediately.
- Clicking: Rapid clicking could indicate a faulty thermostat or electrical issues.
- Excessive humming: While a low hum is normal, an increasingly loud hum might signal disjointed components or an issue with the motor.
- Rattling: Rattling noises could be caused by debris in the unit or a faulty component such as the blower motor or compressor.
- Squealing: High-pitched squealing noises often point to broken motor bearings or a loose or worn belt.
- Any new noises: If your HVAC system suddenly starts making any unfamiliar noises, there could be a larger problem.
