Question:
I am replacing an older 2022 Coleman Mach AC unit. Coleman gives me the 38203-0693 as the replacement for this non ducted unit. I believe the current air distribution box will need to be updated as well. Please advise all part numbers needed for this install.

Hi Terry,
Great question. If you're replacing your older Coleman Mach unit with the Coleman Mach 38203 0693, you'll want to update the ceiling assembly as well. Since this newer air conditioner uses R32 refrigerant, the older non ducted air distribution box is not compatible. Our recommended replacement is the Coleman Mach Quiet Series Air Conditioner, part # CL56AR, along with the Coleman Mach Deluxe Air Distribution Box for Ductless R32 Air Conditioners, part # CM46RR. Those two components are designed to work together and will give you a complete, compatible non ducted setup. Since the Coleman Mach 38203-0693 has been replaced by the newer R32 version, our CL56AR is the correct replacement rooftop unit.
If you don't mind me asking, what prompted you to replace the current A/C? Is it no longer cooling, getting noisy, or are you just looking to upgrade?
