Upgrade your RV's ductless AC with this low-profile complete system from Advent Air. New R32 refrigerant meets 2025 EPA regulations. Not backwards compatible with any AC systems from 2024 and earlier.

Notes:
The low profile AC unit includes an air distribution box with a built-in thermostat. The dial on the left controls the 3 cool settings and the 3 fan speed settings, which let you increase or decrease the airflow. If you add an electric heat strip (sold separately) to remove the chill on cold mornings, then the dial also controls the heat setting. The dial on the right allows you to set the temperature. Additionally, there are adjustable registers on the front and back of the box. These can be tilted up, down, or side-to-side for directing the air where needed. The removable air filter prevents dust and dirt from building up on the fan blades.
If your campsite or generator isn't able to draw the power you need, then you may have difficulty starting your AC unit. The included start capacitor, however, can eliminate this problem. The capacitor stores energy that will later be used to jumpstart the AC. Once the sufficient amount of power has been supplied to the AC, the compressor will start to run, and the internal relay switch will turn the start capacitor off. At the same time, the compressor will send "back voltage" to the relay switch and capacitor in order to energize them for the next startup.
Because your RV is likely already prepped and pre-wired for an AC unit, installation is simple and easy. Most AC units, including this one, are designed to fit an opening that measures 14-1/4" x 14-1/4". Depending on your roof setup, you may need to do minimal alterations. If the opening is larger than 14-3/8" x 14-3/8", you will need to install spacers between the sides of the unit and the opening's edges. If the opening is smaller than 14-1/8" x 14-1/8", you will need to enlarge the hole to fit the unit snugly inside the opening.
On the bottom of the AC, there's a thick, collapsible gasket with 6 noise-reducing foam pads. This provides support between the RV roof and AC and seals the opening to prevent water and outside air from leaking in. Because of this, the use of fresh sealant isn't required during installation.
To install the start capacitor, bolt it to the fan motor support with the included hardware and then route the wires to the run capacitor.
Once installed, the hard plastic cover on the AC can easily be removed for maintenance and cleaning.
2-Year limited warranty covers defective units when installed correctly on approved applications. The warranty does not cover units installed incorrectly. To ensure air conditioner is installed correctly, please see the questionnaire pdf below. A filled-out questionnaire is required for warranty coverage.
If you are not comfortable using a voltmeter (or removing the charge from the start capacitor), you'll want to make a service appointment with your local RV dealer to verify the installation. Print the pdfs below (warranty- questionnaire, warranty dealer information) and take them along with the RV to your local dealer. ASA does compensate dealers for warranty work as outlined in the dealer information pdf. You may be charged by the dealer for time spent investigating the installation.

Gives me an additional 4 inches lower height so I can now get the camper in my garage
Thanks fast service
You were very helpful and it is perfect!
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.
Great service and received air conditioner in two days. Thanks Hannah!
So far the product has been great more importantly, customer service is even better than five stars Jill R Did a great job and I will be doing more business with this company.
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.
Easy installation
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.
it's a great family project everything was like they said it was the videos were helpful
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!
