Yes, the Advent Air RV Air Conditioner, # ACM150B (black shroud) or the the Advent Air RV Air Conditioner # ACM150 (white shroud) can be used as a direct replacement for Coleman Mach ACs if used with the adapter wiring kit # ACCOLKIT. However, I recommend going with the # ACCOL150 or # ACCOL150B as these are the same units with an added start capacitor that helps to jumpstart the AC when camp power or generator power isn't enough.

Hey Jon; I was actually just talking to Furrion about heat options for the Chill Cube yesterday (1/21/2025). At this time, the only way to have heat with this unit is through a furnace on a ducted setup. The Furrion Chill Cube RV AC w/ Air…
