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 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…

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…

Pick a rooftop unit in 13500 btu when you're replacing an AC in that capacity. Decide between ducted or ductless, and note that low-profile or heat pump options are available in this size; some setups now require a complete system with the newer R32 refrigerant. For smooth installation, confirm your connector type (6-pin or 9-pin) and thermostat needs, and on 2-3" roofs be ready for different plates or bolt lengths.
Test-fit hardware and be ready to adjust. Some found long bolts too long and others a little short; shorten or swap as needed for a snug seal. Make sure the baffle doesn't deflect the mounting plate or press into the foam. If installing solo, a lifting aid makes setting the unit easier and helps you keep the gasket aligned as you cinch it down evenly.
It can be simple plug-and-play, but plan for a few checks. Confirm your connector type (6-pin or 9-pin) and whether a new thermostat wire is needed. Some instructions are vague; you may need to remove the EPP evaporator cover to access wires. An electrical box might fit tight and may need to be tilted into place. Double-check all wiring before powering up.
Yes, 13,500 Btu is a common capacity for RVs and has low-profile and heat pump options. Choose ducted or ductless to match your current setup, and note there are high efficiency models at 13.5k. With the switch to R32 refrigerant, plan on a complete system. Verify if you want a wall thermostat or a manual air distribution box before ordering.
Check for thin-roof specifics before tightening anything. Some units covering 2-6" roofs may need a shorter long mounting bolt to avoid the fan shaft. The baffle between air chambers may need trimming and foil tape to close gaps. Ask about a different plate for thinner roofs if available, and make sure the baffle doesn't push into foam or the squirrel cage fan.
