What Is an Air Source Heat Pump
and How Does It Work?
An air source heat pump (ASHP) is an electric HVAC system that can both heat and cool buildings by transferring heat between indoor and outdoor air using a refrigeration cycle.
Heating Mode
In winter, it extracts heat from outside air—even at low temps—and moves it inside.
Cooling Mode
In summer, it reverses, drawing heat from indoors and transferring it outside.
According to the U.S. Department of Energy, air source heat pumps are a cost-effective and energy-efficient solution.
Key Components & Cycle
The system works through a continuous refrigerant cycle
Outdoor Unit
Pulls in outside air using a high-efficiency fan system.
Evaporator Coil
Where refrigerant absorbs heat and transforms into vapor.
Compressor
Pressurizes the vapor, significantly raising its temperature.
Condenser
Releases the heat into your home's air or water system.
