Hey David, you can replace your Coleman Mach 15 with the Coleman Mach Everest part #CM35MR and use the same wiring that's behind the walls. Everything else would need to be swapped out but the wiring can be reused. We only have the Everest in the…
Hey Melanie. The reason you can't find a replacement for your GE ARC15AACBL2 15,000 btu air conditioner is because they phased them out. In 2025 all RV AC systems had to change over to a new coolant called R32. This was a EPA mandated decision.…

Coleman-Mach RV Air Conditioners with complete AC system
Go with a Coleman-Mach complete AC system when you want a full, matched replacement. These systems use R32 refrigerant, so any old R410A components aren't compatible and the thermostat and air distribution box need to be updated too. Choose ducted or ductless and 13,500 Btu or 15,000 Btu to fit your setup and cooling goals.
Plan to install, wire, and test the unit after mounting. Inspect the shroud and cover during unboxing; a small crack near a screw attachment can be cosmetic but should be noted before install. After wiring, run the system to confirm solid cooling performance. Keep ducted or ductless parts matched to your RV's layout.
Yes, you can replace an older unit with a new Coleman-Mach complete AC system. You'll also need a new thermostat and air distribution box because the new systems use R32 refrigerant and older R410A components aren't compatible. Choose 13,500 Btu if that's what you had, or step up to 15,000 Btu if you want more cooling. Pick ducted or ductless to match your RV setup.
Choose Signature for standard RV use and Roughneck if you need a fortified interior for off-road or heavy industrial applications. Both options are available as complete replacements when moving from older R410A gear to R32 systems. Match ducted or ductless to your rig and decide on 13,500 Btu or 15,000 Btu based on your cooling needs.
Select the control style you want up front. Some systems come with control knobs, while others work with thermostat controls. Double-check the control type before ordering so it matches how you plan to operate the unit. If you need thermostat-based operation, choose a system that supports it rather than a knob-only setup.
