discussing heat pump noises

Your heat pump in Birmingham, AL will make some noise whether they’re new or old. However, some sounds that are unusual or start suddenly should indicate that it’s time to call a professional for help. Here are five strange noises that a heat pump makes and what they mean.

1. Screeching

A screeching noise from your heat pump is never a good sign. This sound usually indicates a loose component in the system or that a belt has come loose. If you hear this noise, it’s best to turn off your heat pump and call one of our professionals for help.

2. Rumbling

A rumbling noise occurs due to cavitation. Cavitation happens when there is a sudden change in pressure in the refrigerant line, which causes the formation of bubbles. These bubbles collapse and make a rumbling noise.

3. Hissing

A hissing noise from your heat pump is usually nothing to worry about and is simply the sound of refrigerant flowing through the system. However, if water leakage accompanies the hissing noise from your heat pump, it’s a sign that there is a problem with the evaporator coil.

4. Humming Noises

Humming noises coming from your heat pump are completely normal and are simply the sound of the compressor running. When you hear a humming noise, it indicates that your heat pump is working properly.

5. Clicking Sound

Clicking sounds occur when the heat pump starts or stops. It indicates contracting metallic components or relay switch running. The sound lasts for a short period, but if it extends, it could be an indication of a problem with the capacitor.
