Question:
Will the Coleman-Mach Signature Mach 3 CM97RR replace my old Coleman 13,500 Btu rooftop unit, or do I need more than just the AC on top?

Expert Reply:
Hey Dev! The Coleman-Mach # CM97RR is a good 13,500 Btu replacement option, but it’s the rooftop unit only. If your current Coleman setup is not a newer R32 system, you’ll need updated compatible interior parts too - the newer R32 rooftop units are not meant to bolt onto older ceiling assemblies and controls.
For a ductless setup, use the Coleman-Mach Deluxe Air Distribution Box # CM46RR in addition to the AC unit mentioned above. For a ducted setup with ceiling vents, use the Coleman-Mach ChillGrill Air Distribution Box # CM36RR with that AC unit.
An easy way to check what you have is to look at the data tag or paperwork for your current AC and see if it specifically says R32. Or you can grab a part number off the unit itself or the interior box under the ceiling. Is your camper ducted or ductless, Dev?
