This Avantco 17816485HC evaporator coil is a perfect replacement for the one that came with your A-49R-HC or A-49R-G-HC unit! The evaporator coil is a vital part of your unit's refrigeration system, working with the other components to help your unit dissipate heat and keep the cabinet set to the right temperature.
