Question:
Will this Furion FR26PR replace my duo therm 600315.331 13.5k BTU?

Expert Reply:
Yes, it will Phil. However, you'll also need to replace your air distribution box. The Furrion Chill HE Replacement RV Air Conditioner Unit for Furrion Setup item # FR26PR is just the AC unit that sits on the roof. It's not going to work with your Duo Therm's air box, which has the controls.
I recommend getting the Furrion Chill HE RV Air Conditioner System - Manual - 13,500 Btu item # FR95TD. This is a complete ac system that has everything you need to replace your Dometic. It also has the new R32 refrigerant which is more efficient and what all the new systems are going to. It's better to make this change now because none of the systems or components made before 2025 are compatible with the R32 systems.
Does your Duo Therm system have a thermostat or heat?

Hi Jerred, My current system uses an analog Duo Therm (Dometic?) thermostat mounted to the wall. Id does not have heat. I am not looking to replace that if it is compatible.
