4 Sounds Your Heat Pump Can Make That Spell Trouble in Boca Raton, FL

A heat pump is an essential appliance year-round since it can both heat and cool your home in Boca Raton, FL. If you notice any odd noises from your heat pump that isn’t part of its normal operation, it’s a sign of trouble. Any of the following four heat pump sounds mean you’ll need to call a professional for inspection and any necessary repairs.


It’s normal to hear some humming sounds from the heat pump as it runs because it consumes electricity to keep your home comfortable. If the humming noise originates from the inside or is disruptive, an electrical problem could be the culprit. Other causes of humming noises may include an inoperable fan motor or a faulty component.

Rattling and Vibration

A vibrating or rattling sound could signal a simple problem like a loose cover panel that you can fix by tightening the loose screws. Some rattling sounds may indicate serious issues with the heat pump, like air handler problems or extremely tight coolant piping. Make sure to call an HVAC service technician to fix the faulty heat pump and eliminate the vibrating or rattling noise.


Grinding noises are common in heat pumps that don’t undergo regular tuneups because they’re dirty or lack enough lubrication. When heat pump components need lubrication or become grubby, they produce loud grinding sounds. A faulty motor could also cause grinding noises. Switch off the heat pump to avoid more damage and call a professional for help.


Refrigerant lines transfer heat for heat pumps, and the refrigerant level goes down over time, causing a gurgling sound. If you notice this noise, you’ll need to ask a service technician to top off the refrigerant to avoid damaging your heat pump. Clicking noises during the heating or cooling cycle of a heat pump indicate a faulty capacitor.

These sounds are signs of trouble brewing within your heat pump. Call Preferred Air Conditioning & Mechanical, LLC for quick and friendly maintenance, repair and installation services.
