This AC unit from Advent Air is designed to replace the old or broken Dometic air conditioner on your RV or camper. It plugs directly into your Dometic setup and works seamlessly with your existing, in-good-working-order Dometic air distribution box and thermostat. This eliminates the need of an adapter wiring kit, which saves you time and effort. The AC has a powerful fan and motor that provides a steady stream of air to efficiently cool the inside of your RV on a hot or muggy day. The included start capacitor will help jumpstart the AC. This beneficial upgrade provides the AC a boost when shore power or generator power isn't enough to start it. And everything you need in order to replace your AC unit is included, which makes installation simple and easy.
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), youll 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.

This AC unit replaces the Dometic air conditioner on your RV or camper. AC plugs directly into your Dometic setup to work with your existing air distribution box. Start capacitor jumpstarts AC when camp power or generator power isn't enough.There was a a bit of confusion on having a unit in stock that cost me a few days delay. When the unit was received, it was in good shape and went in where the old unit was without a hitch. It is in operation and working find. I am pleased.
The air conditioner fit perfectly and the interface with the old Dometic Duo-Therm was spot on . I haven't rated the AC until now due to a bad relay in my system that I have since fixed. Hardest part of the job was getting the unit up onto the roof.
Old dometic unit stopped cooling after many years, this has good reviews and I purchased it. Install was a breeze as it was plug and play. Back in business. Cools great and young lady on the phone (Cloda M)was knowledgeable about product.
The unit arrived in an open box with damage 4 days later than my order indicated when I put my payment info in.
Please reach out to me so that I can give you all a chance to earn a proper 5 star review.

Thank you for sending in the pictures! I am so sorry it arrived this way. Shipping can really do a number on some products! I will have our customer service team reach out to you.
What a great deal. So I live on the easy side of Oregon and for those that don't know we get fairly warm in the summer time, like mid 90's to around 105. Well my main AC unit, I have one in my bedroom as well, decided it had served it's life and quit on me. Lucky for me I found this amazing deal on an OEM replacement for my Dometic. When they say it's a plug and play they are not joking. It took myself and 1 buddy to do the entire swap, pulling the old off and attaching new, a whole 30 minutes start to finish. As of right now this AC unit is doing everything I asked for and at a way better price point than a Dometic.
Bought Advent air conditioner as a replacement for a Dometic that quit working. Perfect replacement with easy installation. Arrived quicker than expected too. Very satisfied!!!
My Dometic had a leak after 6 years. I decided to replace it with this Advent and couldn’t be happier. Total install time by myself was about an hour and a half including the soft start install. I watched a couple of videos which helped greatly. It’s shown here with the old unit in front. I’ve had it for about 2 days and it will take it down to 65 degrees.
Box was a little beat up And one small debt in cover. Overall it needs a little bit more cushion or packaging around the back end of the unit

It does look like it had a bumpy ride. Customer Service will be in touch with you. Stay frosty.
A/C unit fit great, i like how etrailer website let me know what units were compatible with my trailer . would buy again
Ease of installation some wiring problems but was rectified. Unit is working hreat
Very easy to install. It is definitely a plug and play setup. The video explains everything in detail including the installation of the run capacitor.
works very well and plug and play.was working in 2 hrs.
5 star. Arrived in one day after ordering. Excellent condition. Easy installation after watching installation video. Highly recommend. Excellent customer service.
I would suggest that anyone looking for an AC for your RV look no further
They had me my replacement AC in 2 days
Wasn't on the phone More than 5-6 minutes an everything was completely as promised!
Great help
Thanks Again
Running great after figuring out the wiring to thermostat.
Bought one last year & now buying another one this year.
Hope this one last many years. I think the units are good but they never get shipped right side up as marked on the boxes.I have been told, the oil in the lines get in the compressor when not keep upright which makes the compressor go bad. installing this one next week but it came layed down also, I will keep my fingers crossed.
Easy, works great. You need a lift to get it up there. Plugged right in where my old one came out.
ETreailer provided us with the AC after receiving the wrong replacement AC from our RV manufacturer at lower price. Great staff. Fast accurate complete service. Everything fit and works with no leaks.
It would not fit where I ordered it for and after a month of calling back and forth trying to find the right hardware I gave up and ordered another unit and kept this one for a rainy day
This was a great upgrade unite coming form a 13K and Very easy install. To the people that are are doing the install them selves, go get a 1/4" Torque wrench and Torgue the mounting bolts down equally. If the instructions say torque to 4LBS then take it to 2 lb then 3 then 4 or 5Lbs... You will not leak that way
Easy install and exact replacement for the old AC.
I have just installed this AC so I do not have any long term experience with it yet. It installed easily and was almost an exact match for my Dometic unit, plug and play.
Overall, the air conditioner as a direct replacement for my duo therm is great. It was an easy, straightforward install. I love the capacitor start. I’m giving it three stars because the heat pump portion does not appear to work.
Installation was super easy! We ran it all last summer with absolutely no issues whatsoever! When our other AC unit finally quits, I'll definitely buy another Advent from eTrailer!!!!
Easy to install, straight swap for the old unit. It provided very good airflow to the front and back of the RV and cooled well also.
Actually didn't require the start capacitor to work with our Onan generator.
Product arrived with cosmetic damage.
Prepare the roof area and clear all debris (1)
Situate the upper unit and offer up the internal frame (2) Adjust position slightly if needed.
Carefully select the internal steel duct height to suit your roof thickness - shown in (3) un-compresssed.
Cinch down all four mounting bolts evenly to compress the foam gasket sufficiently without over-tightening (4)

The unit is still working and in use every day. Still seems like a great investment.
