After a long drive or a full day in the sun, this 15,500 Btu system cools your RV without long, uneven cooldown cycles. It fits larger trailers and RV interiors where higher cooling capacity keeps temperatures from lingering.
A sun-baked RV can hold heat well into the evening, especially after hours on the road or parked in an open campsite. This 15,500 Btu unit delivers 430 CFM of airflow to help bring cabin temperatures down and keep cooled air circulating, so the interior feels more comfortable when it is time to relax.
The included AACDC air distribution box helps connect the rooftop AC to your RV's ducted airflow system, so cooled air can move through the ceiling ducts to vents around the cabin. It also has 2 adjustable louvers at the ceiling assembly, giving you added airflow control in the area directly below the unit. A reusable filter helps catch dust and debris before air moves through the system, and it can be removed, cleaned, and used again.
Roof units can add vibration, outside air leaks, and water intrusion around the opening. A thick, collapsible gasket with foam pads supports the unit at the roof, seals the opening against water seepage and air leaks, and cuts vibration at the mounting point, so the AC keeps running while the cabin stays drier and quieter.
When the cabin temperature changes throughout the day, it helps to have the controls where you can actually reach them. This system includes a wall-mounted thermostat with an LED digital display, letting you adjust the mode, fan, and temperature settings for a single zone. Add the optional remote controller (ADV67QR - sold separately) to make changes from your seat or bed.
Rooftop AC swaps get messy fast when sealing and maintenance turn into separate jobs. This unit uses a bolt on installation, includes a wiring harness, and comes with a UV-resistant hard plastic cover that can be removed for maintenance and cleaning, so you can get the system mounted, wired, and back in service with fewer steps.

Some camping setups ask more from your AC than others, especially when you are running on generator or campsite power. The optional start capacitor (ACMSCKIT) can be added to help the compressor start more reliably. The air distribution box is also prewired for the optional heat strip (ADV34QR) which can help take the chill out of the air on cool mornings. These upgrades are not included, but they give you a way to build out the system for the way you camp.

Still in the box but it all looks great
Great AC, and the cusomter service is great as well
Fast Delivery !
i had some issues with the equipment being damaged , josh took care of everything, i have been in the a/c business for 37 years the most important thing in the service industry is not the problem itself, its fixing the problem , so i can say 5 stars is deserved and i would use you again!
Works great
Was fairly easy to install. Needs better wiring diagram to understand where everything goes. Still don’t understand how to connect old furnace. Was real hot lately but it did a good job keeping the camper cool.
So far so good had a slight problem with thermostat called company took care of it with no hassle very impressed
nice air conditioner kit and good value
Great customer service from Gina. Order was delivered a day early.
Works good cooled camper down from 84 to 74 in about 40 minutes. Installation was easy. Installed by myself in about 2 hours. Replaced ge unit so I didn't have to cut the hole in the roof.
Install was good, wiring was confusing but I finally figured it out then when I went to install the thermostat, the connections section broke off so I had to order a replacement and do expedited shipping so I have it for my next camping trip!
Works Fantastic!! Ordered a Direct Replacement, Installation went VERY smoothly…..
Unit was delivered and it was undamaged. Installed unit with no problems. I turned it on and it operated and cooled. The only problem was I couldn't adjust the thermostat, the screen lit up blue but the display would not show any data. I called Advent Air and they are sending me a new thermostat. Prompt service and very professional technicians.
Outstanding product.
Thank you eTrailer for providing a replacement for our original AC unit. Although the original lasted a long time, it decided to give up on us right before our first camping trip of the summer which had a forecast of being really hot. As I frantically searched for a replacement, eTrailer came to the rescue with the Advent Air RV Air Conditioner System. Our original unit was 13.500 BTU, but we opted to upgrade to a 15,500 BTU unit which has been a great increase in cooling power.
The wiring was super easy to get figured out. And I had the entire unit swapped out and running in one evening.
One note... our existing system had a number of other thermostat wires that were not needed for this installation. In addition, there was a hot thermostat wire (12v) coming back from the furnace in the older installation. It appears that wire is not needed for the new system (based upon other online resources - but no explanation has been found as to what that was used for.) We simply cut it flush and taped the end to keep it from causing us trouble.
The system does a great job of cooling the unit and is much quieter than the original AC. We are SUPER happy with the purchase.
So far so good, a relatively easy replacement of the existing unit (2019 Dometic Duo Therm) despite being manufactured under the updated 2025 coolant standard. Was stoked that the wires were labeled, way to go Advent! You'll need four wires to connect the wall-mounted thermostat. Many of the units made prior to 2025 require 3 wires, so running a new cable might be necessary if your current one only has 3.
I have an Advent air in the bedroom and love it so made sense to get the one for the living room when the time came. It’s super easy to install but the thermostat is GARBAGE. It broke right out of the box when connecting the wires, the Bluetooth option doesn’t work and there aren’t instructions in the booklet for it and it keeps turning itself off every 24 hours leaving my RV hot. I would NOT recommend it.
We have cold air! The system works great but is louder than expected from wind noise due to the design on the louvers. The thermostat cycles this unit on and off very frequently instead of cooling just past set and drifting just above as the dometic system did. The instructions don't mention how to configure the foam plenum for ducted systems. You will need to buy wire nuts for 120v and crimp connectors for 12v wiring. Buy a roll of aluminum ductwork tape to seal things and to cut down on wind noise. I have not yet wired in our furnace, I assume the singular brown wire will signal a relay if I buy one?
Do you have a question about this RV Air Conditioner?

Hey Brendan! Yes, the brown wire is what you'll use to wire in your furnace! I'm glad you're nice and cool and enjoying your new AC :)
