Hello Mike, thanks for reaching out. We do have a solution for replacing your Duo-Therm unit, but we do not offer a direct replacement for this. The best option for a replacement will be to replace the entire AC system. The reason for this is new RV AC units use new R32 refrigerant and these units are not backwards compatible with old AC systems. So for a replacement I recommend the following:
- GE Appliances Deluxe Plus RV AC System w/ Heat - Ductless - 15,000 Btu - Black - Complete System # GE34RR
This comes with everything you need to replace/upgrade your AC system. You get the rooftop unit with heat pump, distribution box, controller and thermostat. This will work with a ductless AC system so please confirm this is what you have.
