Hello Shayne, thanks for reaching out. We do have an option for replacing your Coleman Mach 15 AC, but I am sorry to say there are no plug-and-play replacements for this. Reason being is all new RV AC units changed over to a new R32 refrigerant starting in 2025. These new units are not backwards compatible with old pre 2025 AC systems. So you will need to replace your rooftop unit, controller, distribution box and thermostat. For that, I recommend the following:
- Coleman-Mach Signature Mach 15 RV Air Conditioner System - Ducted - 15,000 Btu - Polished White # CM52RR
This comes with everything needed to replace your AC system. This is for a ducted system. We also have this with a black AC unit part # CM42RR.
