Question:
I need to replace my duo-therm 630515, do you have a plug and play option for that replacement?
asked by: Paul V
Expert Reply:
Hey Paul! Your Dometic Duo-Therm is an old R410A unit. Since everyone had to switch to R32 refrigerant due to the 2025 EPA regulations there are no plug and play replacements available. The new units aren't backwards compatible so the only option is complete replacement with a new system.
Assuming you want to keep the heat pump, I recommend the GE Appliances Deluxe Plus RV AC System. You can choose from the following based on color and capacity. You will also need to know if your system is ducted or ductless.
For ducted setups:
-GE Appliances Deluxe Plus RV AC System w/ Heat - Ducted - 15,000 Btu - White - Complete System # GE85ZR
-GE Appliances Deluxe Plus RV AC System w/ Heat - Ducted - 15,000 Btu - Black - Complete System # GE75ZR
-GE Appliances Deluxe RV AC System w/ Heat Pump - Ducted - 13,500 Btu - White - Complete System # GE52ZR
-GE Appliances Deluxe RV AC System w/ Heat Pump - Ducted - 13,500 Btu - Black - Complete System # GE25ZR
For ductless setups:
-GE Appliances Deluxe Plus RV AC System w/ Heat - Ductless - 15,000 Btu - White - Complete System # GE94RR
-GE Appliances Deluxe Plus RV AC System w/ Heat - Ductless - 15,000 Btu - Black - Complete System # GE34RR
-GE Appliances Deluxe RV AC System w/ Heat Pump - Ductless - 13,500 Btu - White - Complete System # GE64RR
