4 Heat Pump Sounds That Signal Trouble in Rockville, MD

When your heat pump works to heat or cool your Rockville, MD home, you’ll want to pay attention to how it operates and any unusual noises. It may be a cause for concern if you notice any of the following noises from your heat pump.

Grinding and Buzzing

If you hear grinding sounds from the heat pump, it could be that its motor bearings are dirty. When the contacts or coils aren’t functioning well, you’ll hear a buzzing noise. Call in one of our HVAC professionals to inspect your heat pump to determine the cause.

Rattling and Vibrating

A vibrating or rattling sound from your heat pump can be a sign that the screws on the cover panel are loose. Overtightening can cause issues, though, so resolving loose screws should be left to professionals. They may also place a rubber mat below your outdoor unit to absorb any excess vibrations, should the system be in good shape otherwise.

Metal Banging or Thumping

A sound of metal hitting against metal or a consistent thumping noise could mean that the fan blade is bumping into something such as ice, a twig or other debris that got inside the unit. When you hear this, be sure to shut off the system because it can ruin the blade and the fan motor.

Gurgling

A swooshing sound, followed by a slightly louder sound from the compressor, is normal when the refrigerant equalizes. However, a gurgling noise may mean that there is a low refrigerant charge and that you’ll need to get a professional to recharge the coolant.

You should schedule regular heating and cooling maintenance to ensure that your system remains in top condition. Contact one of our reliable Rockville, MD HVAC technicians from Vernon The Heating & Cooling Specialist to set up an appointment.
