Hello Sam; that is a great question! I reached out to Furrion and you will be able to use the Furrion Chill Cube #FR69TD (white) or #FR49TD (black) with your furnace. However, the remote is not capable of operating the furnace at this time. Also, we…
Hey Neil. The 18,000 Btu Furrion Chill Cube RV Air Conditioner item #LC34DX fits a 14-1/4" x 14-1/4" cutout which is pretty standard on RV's. If you meant to write Dometic instead of domestic then yes it'll fit in your existing…
Hey Jon; I was actually just talking to Furrion about heat options for the Chill Cube yesterday (1/21/2025). At this time, the only way to have heat with this unit is through a furnace on a ducted setup. The Furrion Chill Cube RV AC w/ Air…
Hey Mike! The Advent Air RV Air Conditioner #ADV74QR is only designed to work with an R32 setup. Your old unit is going to be R410A, so the old components won't be compatible. Since everything moved to R32 last year due to EPA regulations a…
Hey Kenny, welcome back! The reason for that note is because all of the new systems since 2025 use R32 refrigerant due to EPA regulations. Any 2024 and older systems use R410A and their parts are not compatible with the R32 units. It doesn't mean…
Hey Keith! I can definitely help you find a replacement for your Dometic Duo Therm. However, you're going to have to replace the thermostat and air distribution box as well. Your current setup is for R410A and everything switched to R32 last year…
Hey Doug welcome back! To replace your Dometic Duo-Therm 57915.331, 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, you'll need to replace all…

Hi Collin, welcome back! The most economical replacement is going to be from Advent Air. You will need a complete system since everything moved to R32 refrigerant. If your upgraded thermostat is R32 compatible, or a smart thermostat that got a…
Hi JD; the Furrion Chill Cube #FR49TD air distribution box has a vent on it you can open and close. See the picture attached below. When it is closed it forces more of the air through the ducted system. Assuming you have a ducted system you will need…
Hey Kyle! That is correct. The Coleman-Mach Mach-C Everest has variable-speed cooling and an inverter-driven compressor. However, the Mach-C Everest uses a traditional wall thermostat instead of a remote control. It also works with both ducted and…
Hey Paul! Great question. The Furrion Chill Cube #FR39TD comes with the AC unit and the air distribution box for a ducted setup. The #FR49TD has the AC, ADB, and also adds in a wall thermostat. If you just need the AC then the #FR39TD is the right…
Rooftop RV Air Conditioners for straightforward upgrades
Get reliable cooling without overcomplicating the swap. Rooftop RV air conditioners commonly fit a 14-1/4" x 14-1/4" cutout, making replacements simple. New R32 units aren't backward compatible with old R410A parts, so for ducted setups plan on the correct air distribution box, and add a compatible thermostat if you want the system to control a furnace.
Some rooftop air distribution boxes have a vent you can open or close to send more air through the ducts. Close the vent to force more cooled air into the ducting; open it for more direct discharge. Verify your RV is ducted and pair the rooftop unit with the correct ducted air distribution box.
Installation can be manageable for a careful DIYer, but rooftop units are heavy so a helper is smart. Follow the instructions for the 14-1/4" opening and specified bolt torque. Don't over-torque fasteners to avoid stripping. Seal carefully and test operation after install, then evaluate performance in hot weather.
Expect to swap the older R410A parts for the new R32 rooftop setup, including the air distribution box and controls. If you have a furnace, pick a package with a compatible thermostat or keep a separate wall thermostat for the furnace. Write down your old model and serial so you have them if the controller ever needs attention.
Yes, most rooftop units fit a 14-1/4" x 14-1/4" cutout. Confirm your roof opening size before ordering. New R32 rooftop systems aren't backward compatible with older R410A components, so plan on a matching air distribution box and controls. For ducted campers, choose a ducted kit to tie into your ducts.
