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…
Hey Arkadius, welcome back! Yes, the ducted version of the Chill Cube comes with a remote. However, you're going to need the complete system for a replacement. You can choose from the following based on color: -Furrion Chill Cube RV Air…
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…
RV Air Conditioners with complete AC system for 18000 Btu comfort
Cooling bigger RV spaces is easier with an 18000 Btu setup. Choosing a complete AC system streamlines a full replacement and helps when moving to newer refrigerants—new R32 units aren't backwards compatible with old R410A systems. Match your ducted or ductless layout, and if you want to run a propane furnace from the same controls, pick a package with a wall thermostat or keep the furnace on its own thermostat.
Yes, some 18000 Btu complete systems include a heat pump. You will need a complete system to make the switch, since newer R32 units aren't backwards compatible with old R410A systems. If you want the furnace controlled too, add a wall thermostat; otherwise the remote handles A/C functions.
A ducted setup uses an air distribution box with a vent you can open or close to push more air into the ducts. Close the vent to force more airflow through the ducting. If your RV is ducted, choose a ducted package and decide if you also want a wall thermostat for furnace control.
Use either a wall thermostat package or keep your existing furnace thermostat separate. With a wall thermostat package, the A/C and furnace can work together. If keeping them separate, confirm your current thermostat can run the furnace independently, or swap to a simple furnace-only thermostat.
Not for A/C functions; the A/C won't power a wall thermostat without 120v. To control a 12v propane furnace, supply a constant 12v and ground to the wall thermostat so HEAT mode still works. If the A/C isn't on 120v in cooling modes, an error may appear; it doesn't affect HEAT mode.
