This Avantco 17815868HC condenser coil is a direct replacement for the one that came with A-19F-HC, A-23F-HC, A-35F-HC, A-35R-HC, A-49R-HC, and A-49R-G-HC units. The condenser coil is a vital part of your equipment's refrigeration system, working with the condenser fan and motor to cool down the refrigerant and help your unit dissipate heat.
