What’s That Noise Coming From My Heat Pump in Longwood, FL?

Heat pumps make many different noises, each one having meaning. Here are some common heat pump noises you might hear as a Longwood, FL resident, as well as what they might mean.

Whirring or humming

A gentle hum is normal. This means that the fan and compressor are working correctly.

Clicking

Clicking noises happen when the heat pump starts or stops a cycle. These sounds come from the different components in the system engaging and disengaging.

Clicking noises are usually harmless and not a cause of concern. If the clicking continues throughout the cycle, then you need to call for service.

Hissing

This sound usually means your heat pump has a refrigerant leak. When refrigerant escapes, it makes a hissing sound. If your system is making this sound, it needs immediate attention from a professional technician.

Banging or Rattling

Broken or loose components in the heat pump are the usual culprits when you hear this noise. Sometimes, rocks, twigs and other debris have fallen into the outdoor unit.

If you hear these noises, turn the system off, inspect the unit and remove the foreign objects. Call for professional assistance if you don’t see anything causing the noise or can’t reach it.

Knocking or Thumping

This noise often means your system has a malfunctioning or unbalanced motor or fan. This one requires your immediate attention. Leaving your heat pump to its own devices after hearing this sound will cause further damage that may require the replacement of the entire system.

Prompt attention to unusual noises, along with regular maintenance of your heat pump, will keep your system running efficiently and smoothly.
