Hey Nicholas, thanks for the pics and information. To replace your Dometic Brisk II 9105304474 AC, I recommend the Advent Air RV Air Conditioner System item # ADV92SR in white or item # ADV62SR in black.

There's no way to just replace your AC unit and plug into your air box, you'll need to replace all your AC system components. This is due to the EPA changing the regulations on the refrigerant in the AC units at the beginning of 2025. They've been upgraded to R32 and your Dometic Brisk II has the now obsolete 410a refrigerant. None of the 410a components are compatible now with the newer systems. You will be able to use the existing wiring to power the AC system and connect the new thermostat if yours has one.

The Advent Air RV Air Conditioner System item # ADV92SR in white or item # ADV62SR in black are 15,000 btu systems that include an air distribution box that works in both ducted and ductless orientations. These systems also come with a start capacitor that stores up energy. It's going to really help when the compressor kicks on and needs to draw excess power.

Does your current AC system have a thermostat and do you have air ducts in your trailer? I'm just trying to dial in the right system for you. We've got quite a few replacement options and I understand swapping out everything to replace an older AC unit wasn't what you had in mind.

You can add this information, along with any other questions you have, where it says Add Comment.

My current system has both ducting and a thermostat. What other items will I need for this replacement?
