Hello Robert, thanks for reaching out. The best option for this will be to replace your rooftop AC, controller and distribution box. Do you prefer a wall thermostat, or a distribution box with manual controls on the ceiling? We have options for both, here is what I recommend:
- Advent Air RV Air Conditioner System - Single Zone - 15,000 Btu - White - R32 # ADV92SR
- Advent Air RV Air Conditioner System - Manual - 15,000 Btu - White - R32 # ADV32SR
These are both full AC systems so you get your rooftop unit, controller, and distribution box. Everything you need to replace/upgrade your AC system. Also, these systems will be compatible with both ducted and ductless setups.
I hope this helps. Feel free to reach out with any comments or questions and I will get back to you.

Jesse, I am looking at installing the Advent Air RV Air Conditioner System - Single Zone - 15,000 Btu - White - R32 Part Number: ADV92SR into a customer's unit and I was wondering about the wiring. Would I use the wiring that their current thermostat is using. The reason for replacing their current dometic A/C is that it has leaked refrigerant and will no longer cool. Everything else about the A/C works. Thank you, Justin!
