The evaporator is the coil that is located in a box (called an evaporator housing or plenum) mounted behind the dash or on the firewall in the engine compartment. It receives liquid refrigerant that is metered into it from the expansion valve. As the refrigerant enters the evaporator, it boils into gas form, causing the coils & fins to frost up. The air that is forced through the frigid evaporator coil is ultimately pushed through various ducts and louvers before entering the passenger compartment. The evaporator, along with the Condenser, is the most important part in the a/c system at determining how cold vent temperature is.
Over time, many things can decrease the efficiency of your car’s evaporator. Dirt & debris can block cooling fins and restrict or block air flow, causing marginal or even hot vent temperature or it can simply develop a leak. In some cases, a more efficient replacement evaporator is available. When converting to 134a, it is highly recommended to replace your original evaporator with a more efficient coil if available.
