I don't have a way to know what AC unit you have now but the Furrion Chill HE part # FR92PR is a really great option that comes with an air distribution panel with controls. We have found from testing here that the Furrion units are the quietest and blow coldest. The unit I mentioned is a 13,500 BTU unit but if you wanted a 15,000 BTU unit we also have the part # FR92PR which is better for larger RVs.

If you have the ACTH12 then you should also have the Air Distribution Box #ACRG15 which will have a control box for your wiring from the rooftop unit #ACM135 and the thermostat. This air distribution box and thermostat will wire up exactly the same…

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.…

Hey Tim welcome back! Your ARH15AACBL2 GE AC unit has the old 410a refrigerant in it so the GE Appliances item #GE64FR you were looking at isn't going to work as a replacement. The EPA mandated R32 refrigerant has been used in all new AC's…
