Heat Pump

In Plain English

An HVAC system that provides both heating and cooling by moving heat rather than burning fuel.

Definition

A reversible refrigeration system that can provide both heating and cooling by reversing the direction of refrigerant flow. In cooling mode, it operates as an air conditioner; in heating mode, it extracts heat from the outdoor air or ground and delivers it indoors. Heat pumps are highly efficient in mild climates because they move heat rather than generate it through combustion.

Example

A 3-ton air source heat pump provides year-round comfort, with a COP of 3.5 in heating mode at 40°F outdoor temperature.
