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…

Spread cool air through your camper with ducted RV air conditioners. Look for units that fit a 14-1/4" x 14-1/4" roof cutout, and use an air distribution box with a closable vent to push more airflow into the ducts. Replacing systems built before 2025 can require a new air distribution box due to R32 refrigerant updates, and if you have a furnace, plan for a compatible thermostat.
Plan on lifting help—the rooftop unit is close to 80 lbs. A DIY swap can be done in a few hours, but set aside extra time if it's your first install. Confirm the 14-1/4" x 14-1/4" cutout and follow the torque specs in the instructions to avoid stripping hardware.
The air distribution box has a vent you can open and close. When it's closed it forces more of the air through the ducted system. Check that your ducts are clear and sealed to help reduce airflow noise and improve cooling to the rooms you want.
You'll need a complete new setup so the parts work together. Expect to replace the air distribution box, and if you have a furnace make sure you have a thermostat to control it. You can keep using your wall thermostat for the furnace while the A/C runs off the remote and ADB controls. Write down your old controller's model and serial number for reference.
Yes, most ducted RV A/Cs fit a 14-1/4" x 14-1/4" cutout, which is pretty standard on RVs. Verify your roof opening before ordering. If you're replacing an older unit with a new model using R-32 refrigerant, plan to swap the air distribution box because anything made before 2025 isn't compatible.
Don't expect a much quieter system just from changing the unit. Mechanical noise can be low, but the sound of the air flow is often just as loud, which is due to ducting. Check duct design and vent positions to help reduce airflow noise.
