How Automotive AC and Heating Works

Heating is a simple process. Hot coolant gets drawn through a heater core, where a front-mounted fan blows air over it to send warm air through the vents and into your passenger space.

Air conditioning is more involved. It starts with refrigerant getting compressed in the compressor system, where it turns into a hot gas.
