An A/C cooler is a heat exchanger. The condenser cools high-pressure refrigerant gas to turn it into a liquid. The evaporator cools cabin air by absorbing its heat into low-pressure liquid refrigerant. Both components use aluminum fins to maximize surface area and speed up heat exchange.

A/C Cooler
A general term for any heat exchanger in the vehicle's air conditioning system, such as the condenser or evaporator, that cools refrigerant or cabin air.
Frequently Asked Questions
No. The radiator cools engine coolant. The A/C condenser (cooler) sits in front of the radiator and cools refrigerant.
The evaporator under the dash accumulates condensation. This wet, dark environment allows mold and bacteria to grow on the cooling fins.
Spray a dedicated foaming coil cleaner into the evaporator drain tube or fresh air intake to kill mold and wash away dust.
