To effectively troubleshoot cooling issues with your heat pump, it’s crucial to have a good understanding of how heat pumps work and the common cooling issues that may arise.
How Heat Pumps Work
Heat pumps are highly efficient HVAC systems that can provide both heating and cooling for your home. They work by transferring heat from one area to another using refrigerant. In cooling mode, the heat pump absorbs heat from the indoor air and releases it outside, resulting in a cooler indoor environment.
The basic components of a heat pump system include the compressor, evaporator coil, condenser coil, and refrigerant. The refrigerant circulates between the indoor and outdoor units, absorbing heat from the indoor air and releasing it outside. This process is reversed in heating mode, where the heat pump absorbs heat from the outdoor air and transfers it indoors.
