5 Noises You Don’t Want to Hear Coming From Your Heat Pump in Seguin, TX

February 23, 2022

Your Seguin, TX, heat pump will naturally make some noise while running. The most common is the whirring sound your outside unit makes as the fan spins. Listen for these five noises you don’t want to hear from your heat pump and act to solve them quickly.

Rattling Noises

Rattling commonly means something in your system has come loose. This could be as simple as loose air handler housing or the condensing fan cage. However, it may also indicate internal issues that need professional attention, like a broken component inside your compressor.

Loud Buzzing or Humming

Buzzing or humming from your unit commonly indicates a problem with one of the electrical components. This could be a simple repair like the compressor capacitor wearing out. It may also indicate a more substantial issue, like a blown fan motor.


A gurgling sound likely indicates your system has a low refrigerant charge, which significantly reduces its efficiency. This is one of the items tested during routine heat pump maintenance by a qualified professional.

Grinding or Screeching

Your fan motors have bearings inside that allow them to spin properly. Over time, those bearings may become contaminated, which will wear on them, causing them to stop rolling freely. The result is initially a grinding sound that eventually evolves into a screech.

Clanging Noises

Loud clanging, like metal on metal, tells you that the compressor fan blade is hitting something. This could be some debris, like a twig, or a component that’s come loose and is in the way. Ignoring this not only creates noise pollution but also risks throwing your fan off balance and ruining your motor.

Take care of loud noises from your system early to prevent greater damage. Call the experts at Legacy Home Services to schedule your heat pump repair today.
