Advent Air RV Air Conditioners
- Complete AC System
- 13500 Btu
- Non-Ducted
- Cool Only
- Black
- Advent Air
- Single Zone
- Rooftop
- Standard Height
After a long drive or a full day in the sun, this 13,500 Btu system cools your RV without long, uneven cooldown cycles. It fits smaller trailers and standard RV interiors where steady cooling matters more than extra capacity.
Highlights
- Cools Your RV After Hot Days: 13,500 Btu output and 430 CFM airflow help bring cabin temperatures down after travel, sun, and warm campsite afternoons.
- Made for Non-Ducted RVs: Included AACNDC air distribution box sends cooled air directly into the cabin, with no ceiling ductwork required.
- Touch Controls at the Ceiling: Built-in thermostat and flat touch controls on the air distribution box let you adjust mode, fan, and temperature.
- Fits 2-1/2" to 5-1/2" Roof Thicknesses: AACNDC air distribution box is designed for RV roofs within this range, so you can confirm fit before installing.
- Seals and Cushions the Roof Opening: Thick gasket and foam pads help block water and outside air while reducing vibration at the mounting point.
- Ready for an Optional Heat Strip: Prewired for the optional electric heat strip, sold separately, to help take the chill out of the air in cooler weather.
Features to know about
Pulls Heat Out of a Hot Cabin
After a long drive or a full day parked in the sun, your RV can hold heat in the roof, walls, furniture, and cabinets well into the evening. This 13,500 Btu air conditioner delivers 430 CFM of airflow to help bring cabin temperatures down and keep cooled air moving, so the interior feels more comfortable when it is time to relax.
Seals and Cushions the Roof Opening
A good rooftop AC install needs more than cold air. It also needs a solid seal where the unit meets the roof. The thick, collapsible gasket helps block rain and hot outside air from entering through the opening, while the foam pads help cushion the unit and reduce vibration at the mounting point. That helps the AC run securely while keeping the cabin drier and quieter.
Direct Airflow for Non-Ducted RVs
In a non-ducted RV, cooled air comes straight from the ceiling assembly instead of traveling through ductwork. The included AACNDC air distribution box has adjustable louvers on the front and back so you can move air across the cabin. That gives you more control over where the cool air goes in the area where the AC is mounted. The removable, washable air filter traps dust and debris before it reaches the fan blades to keep you AC unit cleaner.
Touch Controls Built Into the Ceiling Assembly
This system keeps the controls simple by building the thermostat into the air distribution box, so there is no separate wall thermostat to mount or wire. The flat touch-control panel lets you adjust mode, fan speed, and temperature right from the ceiling assembly, making it a straightforward setup for non-ducted RVs where the cooled air comes directly from the unit.
Easier Rooftop Installation and Maintenance
Replacing a rooftop AC is easier when the main pieces are designed to work together. This system uses a bolt-on installation and includes the wiring harness needed to connect the rooftop unit to the air distribution box. Once installed, the uv-resistant hard plastic cover can be removed for maintenance and cleaning, so you can access the unit when it needs attention. If you'd like help installing your air conditioner, check out our Installer Locator to find an installer near you.
Optional Upgrades for Startup and Cooler Weather
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.

Added this second airconditioner to my Thor Vegas. No more struggling to keep cool. The airconditioner is more efficient however it is not very quiet. Keeps the camper cool though.

Arrived sooner than expected. Fit in the vent opening with no problems. Installation was straight forward. This went on a Northstar Larado SC truck camper. It didn't take long for the camper to cool down from 88 to 72 sitting in the sun all day. Ran it for 6 hours without any problems...

Just got back from a trip to the beach it was a lifesaver!!! The Advent air ac unit performed like a champ in 100 degree heat. Installation was pretty straight forward they need to make the bolts a little longer.

first let me say, my star rating only reflects on etrailer by the fact I gave this one extra star because of their nice website and fast shipping.
As to the AC, it does cool and installation was a breeze, and that's where the good ends. I bought this for the bedroom on my older 5th wheel. Yes I know it doesn't claim to be a "quiet" unit but dang. running fan only it's 60-62db, when the compressor kicks in it's 64-70db. my 19yr old dometic in the main part of the trailer maxes out at 61db. searching the claim is 45db and it's no where near that ever. Honestly if it wasn't for how good etrailer has been to me over the past few years ordering stuff this at best would be 2 stars. if you are thinking of a bedroom unit, do NOT buy this one.

I am super happy with both the AC unit and the heat tape. I’ve noticed that when beside other units with AC, this one is much quieter and I love the smaller size.

Installation was straight forward, instructions were clear. Soft Start that is included is another great add. I was able to start and run the AC on High Cool off my 2000 Watt Generator. Just a trial run but ran for 20 min on high with no issues. I would suggest that you Lap seal under the AC gasket for just added seal. Also I would suggest torquing the AC unit down a few times after the intial torque. Wait 30 min between. I did it 4 times.

Only problem we had was bolts to roof we're 1/2 inch to short. Bought longer bolts and problem solved also note to people that also install this unit the opening doesn't have to be perfect like they say as long as bolts go through your good 14x14 is fine in my opinion.

Installation was straightforward and is cooling well. And it's quieter than my previous one. The only issue was that the documentation showing dimensions around the opening were wrong.

I am glad the installation was straightforward and it is working well. Tell me a little more about the dimensions around the opening. Did you have to fill in some gaps or was it too large and you needed to open it some more? We might need to update those instructions!

Only 4 stars because I just finished installing it tonight. Installation instructions were easy to follow and it fired right up once install was complete. If it still works good down the road I’ll give it 5 stars. Sure beats the $3,200 quote by an rv dealer to install one on my weekender horse trailer.

Me and my wife were able to install it no problem. She read the instructions and I did the labor work! I would double check on how much you tighten the bolts down. Over all I gave it 4 stars only cuz I haven’t taken the rv out in July to test it against the heat.

The unit runs and cools nicely, but with the thermostat set at the coldest, it doesn’t get as cold as I would expect before the compressor kicks off.

- Replacement AC for Coleman Mach 8000 on 2004 Winnebago Sightseer 35NHi David; the Furrion Chill HE Replacement RV Air Conditioner for Coleman Setup # FR82PV you looked at is what we would have previously recommended. However, we have run into compatibility issues so I can't say with absolute certainty it will work as a plug and play replacement. Since everything has switched to the new R32 refrigerant following the 2025 EPA regulations now is a good time to swap out the entire system. This avoids the need for a complete replacement down the road if a...
view full answer... - Replacement AC System for Old Carrier Ductless AC SystemHey Jim! Yes, there are definitely options to offer them. It looks like that is an old Carrier system, which uses the standard 14-1/4" x 14-1/4" roof opening. The 99-00469-00 ceiling assembly they have is the non-ducted/free-blow version so this should be a ductless setup. Everything has moved to R32, so they will need a complete replacement. I recommend one of the following: -Advent Air RV Air Conditioner System - 13,500 Btu - White - Non-Ducted - R32 # ADV77QR -Advent Air RV Air Conditioner...

To replace your 13,500 btu Dometic Duo-Therm Penguin model 620526.321, I recommend the Advent Air RV Air Conditioner System item # ADV87QR for a ducted setup or item # ADV77QR for a ductless orientation. There's no way to just replace your Dometic AC unit and reuse your old controller, you'll need to replace all your AC system components. This is due to the EPA changing the regulations on the refrigerant in the AC units at the beginning...
view full answer... - Is There A Way To Reduce Startup Surge Power When Using Advent Air AC Unit On Winnebago Minnie RV?Hi Jeff, yes there is! For your 2020 Winnebago Minnie Winnie 22M, I’d first match the kit to the way your current AC is set up. If your Minnie Winnie has ceiling ducts and a wall thermostat, I’d look at the Advent Air RV Air Conditioner System - 13,500 Btu - Ducted - Black # ADV59QR, or the 15,500 Btu ducted kit # ADV69QR if you want the higher-capacity option. If you have no ceiling vents you'll instead want 13,500 # ADV27QR or 15,500 # ADV49QR. For generator or off-grid camping, the...
view full answer... - Can I Add Remote To Advent Air AC System In 2022 Thor Sequence Camper Van?Hi Rachel! The Advent Air remote, part # ADV67QR, can only be used with the smart wall thermostat that comes with the ducted Advent Air kits, like the Advent Air RV Air Conditioner System - 13,500 Btu - Ducted - Black # ADV59QR or the 15,500 Btu ducted kit # ADV69QR. It is not compatible with the non-ducted Advent Air kits, like # ADV27QR or # ADV49QR, since those use the controls built into the air distribution box instead of the smart wall thermostat. Since your 2022 Thor Sequence is...

The Advent Air RV Air Conditioner System - 13,500 Btu - Non-Ducted - Black # ADV27QR would be the closest style, or you could step up to the 15,500 Btu non-ducted kit # ADV49QR if you want more cooling capacity.

For your 2019 Keystone Passport 2400BH, I’d bet you have a ducted setup since that’s a larger travel trailer, so I’d look at a ducted Advent Air kit like the Advent Air RV Air Conditioner System - 13,500 Btu - Ducted - Black # ADV59QR, or the 15,500 Btu ducted kit # ADV69QR if you want the higher-capacity option. If yours happens to be a ductless setup instead, then you’d want the 13,500 Btu non-ducted kit # ADV27QR or the 15,500 Btu non-ducted kit # ADV49QR. The...
