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…
Under-Bench RV Air Conditioners for Clear Roof Space
Keep your roof clear for solar or cargo with under-bench RV air conditioners that mount inside instead of on top. Installation can include floor cutouts, with heat vented through the floor, and you'll run air ducting from the side openings that is not included. A smart fit when you want cooling without giving up rooftop real estate.
Yes, it works well when space and roof real estate are tight. Under-bench placement keeps the roof clear and can pair with battery or solar builds. Verify under-bunk clearance and plan the floor cutouts for airflow and drains. If powering off-grid, match the unit's demand with your battery and solar capacity.
Expect floor work. Installation can require openings in the floor for air flow, heat rejection, and drain pipes. Air ducting runs off side openings; it may not be included, so verify if ducting or an all-in-one package is provided. Use a cutout template or exact measurements to place holes accurately.
It keeps the roof clear since the unit installs inside. That helps avoid moving or removing solar panels. Make sure you've got space under a bunk or bench for the body and duct runs. If you plan to run it from a battery or solar setup, confirm your system's capacity and the unit's power draw before installing.
It depends on the control mode. In auto mode, the fan may not run all the time; on fixed high or low, it can run continuously. Check whether your unit includes a wall thermostat or handheld remote and use those to set modes. Review the manual to confirm how your model behaves.
