Heat pumps have typical noises they make when running. While the system works to create a comfortable indoor temperature in your Pittsburgh, PA, home, certain sounds can indicate potential problems. Here’s a guide to heat pump noises you shouldn’t ignore.
Hissing and Gurgling
If you hear a hissing or gurgling sound from your heat pump, this could signal a refrigerant leak. Refrigerant is the key ingredient that allows your heat pump to transfer heat in and out of your home.
A leak means there’s less refrigerant circulating. This will make your system work harder and will heat or cool your home less effectively. If you hear hissing or gurgling, leave your home and call an heat pump repair service technician right away to address the leak and prevent further damage.
Screeching or Grinding
A screeching or grinding noise from your heat pump is a bad sign. This could indicate worn-out bearings or other internal component issues. These problems can lead to extensive damage if left unaddressed.
Loud Thumps or Vibrations
An occasional thump might be normal, but frequent loud thumps or vibrations are not. This could come from debris stuck in the fan or loose components. These issues can damage the fan motor and other parts of your heat pump.
Unusual Clanging or Rattling
If you hear it consistently, clanging or rattling heat pump noises are cause for concern. This could happen by screws coming loose or even broken components inside your heat pump.
Such sounds also may indicate that a vital part has shifted out of position. Having maintenance done on your system at least once per year may help catch some of these issues before they occur or worsen.
If you hear any of these concerning noises coming from your heat pump, don’t hesitate to call a licensed HVAC service technician. For HVAC repair or installation services, call our team at Woodruff and Smith Heating and Cooling, Inc.
