Upgrade your RV's ducted or 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 AC unit includes an air distribution box with a built-in thermostat. The thermostat has an LED digital display that lets you control the mode, fan, and temperature settings. If you add an electric heat strip (sold separately) to remove the chill on cold mornings, then the thermostat also controls the heat setting. 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.

great service Brandon G did a wonderful job had no problem installing he gave me all the info I needed to get the job done is working great hope I will be able to work with him next time
Fast shipping. Thank you.
Bought to replace a 3 year old Domestic. Very pleased with the operation and ease of installation. I did go with an entire system and happy I did even though the unit replacement would have worked. I like the updated thermostat and the 3 adjustable vents.
Fast delivery
Unit came damaged, I opened it up on a Thursday and immediately called and Rochelle had a replacement to me on Saturday and installed on Sunday. Worked perfectly, the online video's are helpful. Some more detailed instructions with pictures would be a suggestion. I feel like I torqued the bolts, but it seems like it is almost excessive torque. The instructions do say the seals will crush to about a half inch which is quite a bit of tightening. Overall very happy and happy with the service from Rochelle to get the replacement fast and the call tag for the old one was called in and picked up on a Monday so all is good.
I installed the unit my self and it work great
Very knowledgeable about product and extremely helpful. Would use this company again. Thank you Natalie
Just installed it seems to work fine .... I'm gonna test it out in a couple weeks
The delivery was perfect, but I haven't installed it.
Perfect set up for my rv thanks!!
Delivery was quick - two days. The AC arrived undamaged. E trailer has plenty of great installation videos which made the process smooth and uneventful. Everything performs as promised. For some reason Advent air conditioners don't come with a hard start capacitor included and they were on back order virtually everywhere online. So the 2 week plus wait for that was a bit annoying, but by no means a game changer. Basically Advent us a great unit at a great price that was easy to install diy.
Air conditioner seems to work well so far, and is quieter than my old domestic unit. Installation instructions could be better, I had to figure out the wiring on my own. This uses a 4 wire thermostat, my old unit used a 3 wire so I had to run an additional wire.
I’m not a fan of this unit at all it does not keep up like a 15k btu should !!!!
arrived promptly and was well packaged.
Do you have a question about this RV Air Conditioner?

What do you mean by keeping up? Is it not cooling quick enough or does it not seem to be cooling at all? AC units are only meant to cool by around 20 degrees lower than the ambient temperature. There may be some things causing an issue too so if you want to let me know a little bit more about what you mean I can see what steps we can take to get that working well for you.
