Is this right for you? Product Expert Kathleen M says:

Yes, if you:

  • Find it easier to use a wall mounted thermostat rather than one built into the air distribution box
  • Are adding an AC where one didn't exist before or just want all new components to completely replace an old one
  • Have a darker colored RV and you want the AC on top to match

No, if you:

  • Run your AC off a generator and need a capacitor to help get it going
  • Camp in very humid or extremely hot areas that will need more Btus to keep you cool
AC unit for ducted or ductless system lets you replace or add a new AC to your RV. Wall thermostat has an LED display and controls the mode, fan, and temperature settings. Air distribution box has 3 slotted registers for maximum airflow. Great Prices for the best rv air conditioners from Advent Air.

Works !! great I really like the thermostat make Shure you have ducked vent system I installed this on an enclosed trailer so it only blows to the rear but works fine!


Comments
The unit is also compatible with ductless systems.
-- Etrailer Expert Mike L - 09/24/2022


by:

I’ve only had the chance to run this once, being I am totally rebuilding a 1982 nomad trailer.
It seems to work just fine, but I’ll have to get the trailer completely livable to make sure it does the job.
The installation was pretty simple and went smoothly.




by:

AC works great but you are pretty much on your own for installation. Instructions are not great. Made a phone call to etrailer and they said IDK. I figured it out but it really does work well.


Comments
We have an install video of this piece that I will attach, but when it comes to specific questions on air distribution, our techs do not have a HVAC certificate so we recommend calling the manufacturer.

Review from a similar Advent Air AC w Thermostat in RV Air Conditioners


The company done great letting me know about shipping and arrival date . Unit did sustain some shipping damage . Main frame base was dented. Install for a replacement unit was not bad . Had to rework the opening and adjust mounting brackets . Instructions were easy to follow . The addition of the optional plenum for thicker roofs was a time saver . Wiring was a bit of an issue . No where in the product description or instructions did it state about having to supply additional 12vdc . Most units use a step down transformer in the PCB . This unit does not come to find out . Could not figure out why the thermostat harness didn’t have 12v dc coming out . After a call to Advent , I was informed to supply 12Vdc from an outside source ! After this hiccup, the job went smoothly. Unit does a great job cooling, and is quiet. Thermostat is easy to navigate through. Unit looks nice inside and out . Just not sure how long the rubber bands are going to hold up retaining the filter in the Florida heat .


Comments
The unit has performed very well. No issues thus far . Still very cool and quiet.

Review from a similar Advent Air AC w Thermostat in RV Air Conditioners


Great product, put in a 2022 winniebago vista, one AC just wouldn't cut it. Other that than cutting the hole in the roof, pretty easy install. So now I have a new AC with its on power and extension cord.

Review from a similar Advent Air AC w Thermostat in RV Air Conditioners


Had to manufacture air distribution box since ac unit only comes with side air outlet. The supplied version is designed for side to side plenum not front to back like I have. Had issue with thermostat installation but was digital power box fault. New one was sent by manufacturer. Once all things got done it cooled the RV. Recommend unit be used only for side to side plenum or single straight out. It is not universal with parts supplied as stated in brochure.

Review from a similar Advent Air AC w Thermostat in RV Air Conditioners


AC Unit performs well. The Air Distribution Box was looks very nice, but is advertised for ducted or ductless installations. The large output vents on the distribution box are blocked off with an insulated plate, forcing all the air to go out the tiny vents on the sides. I contacted eTrailer support to determine if removing the insulated plate was allowed, but they recommended contacting the manufacturer. I contacted Advent support and they were surprised to learn that the Air Distribution Box was being marketed as Ductless, as it is intended for ducted systems only. Advent support did indicate that I could remove the insulated plate if I desired. After removing the plate, airflow dramatically increased (shocker, I know) and I am thrilled with the performance and the remote thermostat. (Advent promised to contact eTrailer and discuss the ducted/ductless marketing, but since it's still up as ductless, I guess they either didn't follow up or eTrailer decided that it will work)

Review from a similar Advent Air AC w Thermostat in RV Air Conditioners


It takes a very long time to cool down the small space
Very very noisy impossible to sleep with a/c on
Defenetly the wrong purchase.
I am very sorry for buying this two units from you.
If I have a choice I would replace them asap.

Review from a similar Advent Air AC w Thermostat in RV Air Conditioners


This ac was so easy to install!!! I’ve never installed an AC before in a camper and replacing my roof vent with it couldn’t have gone more smoothly. The instructions left a little to be desired as they didn’t translate very well to English and skipped the key component of the fact you have to have a 12v line ran to the unit from a separate source. Other than that it was perfect and installed in about an hour and a half.

Review from a similar Advent Air AC w Thermostat in RV Air Conditioners


My unit it throwing a E5 code and want come on


Comments
Thank you for your review on the AC unit. The e5 error means there is a communication error between the thermostat and the relay kit. This can be due to dust or moisture on the connections or even a loose connection. I recommend to take a look at all of those connections.

Review from a similar Advent Air AC w Thermostat in RV Air Conditioners


My ac system is unremarkable! With a 2 unit RV, my other unit never has had to run full time. I will be replacing the old unit soon and will definitely be purchasing the same brand. Satisfied customer!!!

  • What Air Conditioner do You Recommend for a Trailer with a Thin Roof?
    I have just the unit for you! We get this question often when considering air conditioners for trailers with thinner roofs. With your 1.6 thick roof, I recommend using the Advent Air RV Air Conditioner w/ Air Distribution Box and Wall Thermostat - 13,500 Btu # ADV44FR. Even though this unit requires a roof thickness between 2-1/2" to 5" thick, there is a way to make a custom plate to work around this requirement provide your roof with the thickness you need. You can do this by making...

  • How to Control Flow Of Condensation from Advent Air RV Air Conditioner
    The Advent Air RV Air Conditioner w/ Air Distribution Box and Wall Thermostat, # ADV44FR has gaskets that seal the unit to the roof preventing water intrusion and allowing accumulated moisture to evaporate without entering the RV. This is designed with a discharge port to evacuate any condensation generated during operation and while not necessary, you can redirect any accumulation by fabricating a drain tube. This would certainly allow you to control the flow of excess that is generated...

  • Can Advent ADV44FR RV Air Conditioner Be Mounted Vertically
    The # ADV44FR Advent RV Air Conditioner shouldn't be mounted in the way you describe. If you did so, the compressor would be sitting on its side and wouldn't receive the proper lubrication, which would quickly cause the compressor to fail. The unit is meant to be mounted to the roof of a vehicle so the output feeds through the underside through a 14x14 inch opening in the vehicle's roof, as shown in the linked install video.

  • Troubleshooting An Advent Air RV Air Conditioner That Doesn't Turn Off When It Reaches Set Temp
    The temperature probe for RV AC units is actually up in the air distribution box controller which can kind of throw off what temperature the unit thinks it is. Hot air rises and can get trapped up by the probe causing it to think it's still not where it needs to be. The typical fix for this is to adjust the air dampers in the distribution box and/or to keep the fan running so that it circulates the cool air up to the probe. As for the wires, there shouldn't be any issues with them being...

  • Air Conditioner That Is Non-Ducted With A 13,500 Btu Capacity And A Thermostat Recommendation
    While we don't carry a Dometic AC that is non-ducted, and is a 13,500 Btu unit, I have an alternate solution. The Advent Air RV Air Conditioner w/ Air Distribution Box and Wall Thermostat # ADV94FR will work great for you. This unit has a 13,500 Btu capacity, is non-ducted, and has a wall mounted thermostat. This unit is white in color, but if you prefer black, you can use # ADV44FR instead.

  • Replacement for Carrier 13,500 Btu Air Conditioner & Heat Without Thermostat

  • Recommended Replacement For A Dometic Duo-Therm RV Air Conditioner Rooftop Unit
    To replace your current Dometic condenser unit I recommend the Advent Air Replacement RV Air Conditioner for Dometic Setup w/ Start Capacitor # ACDOM150. This unit comes with a wiring harness adapter that makes it a simple plug-and-play installation so that you don't have to mess with any of the wiring to your thermostat. This unit also comes with a start capacitor that jumpstarts the AC when a campsite or generator doesn't provide enough power, which will prolong the lifespan of the unit.

  • Air Conditioner Recommendation For 24 Foot x 8 Foot Enclosed Trailer
    For a 24' x 8' enclosed trailer, you're looking at about 200 square feet, and for that size, I recommend a 13,500 Btu air conditioner, which will more than suffice for that space. I also highly recommend a start capacitor to go with the AC in order to ensure your unit always has enough power to start up whenever you need. With that in mind, there are two really good options for you, both from Advent. One has a thermostat and controls directly on the air distribution box, and the other...
