Thanks for letting us help Stu. Unfortunately, you'll need to replace the entire A/C system, not just the rooftop unit. In 2025, an EPA-mandated industry-wide transition phased out the use of R410A refrigerant in favor of R32 refrigerant. Because of this change, the newer R32 rooftop units are not compatible with the older R410A air distribution boxes, control boards, or thermostats.

For a comparable replacement, I'd recommend the GE Appliances Deluxe Plus RV Air Conditioner System # GE72ZR. This is a 15,000 BTU, non-ducted system that includes the rooftop unit, air distribution box, and thermostat, so you'll have everything you need for a complete, compatible installation.

Is your system controlled via a thermostat or directly from the air distribution box?
