Advent Air Dometic Plug-In

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.


Start Capacitor

Advent Air Start Capacitor

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.


Simple Installation

Advent Air AC Installation 15,000 BTU

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.


Advent Air AC Collapsible Gasket and Foam Pads

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.

One little issue with the shroud around the condenser was rubbing and causing a lot of noise. Not a big deal. Trimmed with a utility knife and all good. It also is not exactly plug and play. It takes some trouble shooting to get the wiring correct with the furnace and AC to work with the thermostat



- ACDOM150
by:

Air conditioner works very well. Have owned the unit for over one year. Only reason for 4 stars instead of 5 is that there’s has been a few times where the unit stopped working and we have had to turn it off and back on to get it restarted. Other than that it has worked very well.

Ecxellent customer service. Installed today. Easy, plug and play. Fired right up no problem.

I upgraded from my Dometic 13500 Brisk 2 to the Advent 15000. The installation was flawless, but, the installation is not entirely seamless. My Dometic had a two speed fan while the Advent 15000 has a three speed fan. I believe that the Advent is running on the medium and low speed. The unit cannot defeat the Florida heat. At 99F the unit only dropped the temp 8 degrees. The air at the registers seem to be cold, but, the airflow was not what I expected from the 15000 unit. I’m hoping that the Advent ACTH12 thermostat will work. It doesn’t appear that etrailer sells them without the AC cover. Without the initial high airflow to defeat the heat, this unit will not make muster in the south. To be fair, I’m giving a 5 for the customer service and swift shipping. All the guys got me this far, they are terrific. I submitted a question for the additional information needed to get it right. I checked all the QA&A and comments for anyone that has experienced my problem. A couple fellows upgraded but said it was all good without mentioning the three speed difference. My guess is that they live in a cooler climate or don’t realize the 15000 has three speeds. If I get the Advent thermostat and it solves my problem I will readdress my comment and also update the Q&A page.

It did come fast. If you are replacing an existing AC unit (even a Dometic unit) you will also need the ACDB ceiling vent assembly, as your old vent will not work with this. That begs the question - why do they even offer the ACDOM150 ? What you need is the ACM150C. I ordered the ACDOM150, then learned the hard way I also need the new vent. Had to place a new order for the vent. Wasted time and money for shipping on the 2nd order. Not nice to learn this after the struggle to heft the AC unit onto the roof of my RV.


Comments
Weve learned from our contact at Advent Air that this unit will work with an existing vent assembly if the vent assembly was made after 2008/2009. If the vent inside your camper is older than 2008, you will want to get an updated vent assembly such as part # ACDB

Very satisfied with the unit. Delivered quickly. Easy to install. Had no problems with the installation. Only time will tell if the unit last but as far as the ordering and installation, I have no complaints.


Comments
I wish I could say it is working great but I have to report the unit did not cool after a few days. Had to take the RV to my local dealer for the unit to be a warranty exchange and have them install it. The new exchanged unit only lasted four months and had to replace with a new unit of a different brand while on a vacation trip. With all the problems I had, I would not recommend this product anymore. Its cheaper for a reason.

SUPER pleased with the product. It was exactly as described and performs exactly as expected. The installation was simple, do-it-yourself, (less than 30 min) using 1 screwdriver and 1 nutdriver. The 15,000 btu unit cools my 41' park model in less than 20 min. Super quiet, and efficient. This unit was used to replace a Dometic Duo Therm and I did not have to modify anything...straight plug and play! Many thanks to the team at etrailer for the great service and lightning fast shipping! I will definitely be a loyal future customer.

Review from a similar Advent Air AC Unit in RV Air Conditioners


This was a replacement for a Carrier V 15,000 roof top. Still using the Carrier control panel and ducting. Runs and cools good but cycles more than our older advent air 13k ductless in the bedroom. Cycling may be caused by the ducting instead of ductless. It is quieter than the old Carrier V and seems to cool the same.

Review from a similar Advent Air AC Unit in RV Air Conditioners


Installing was quick and efficient. At first when I hookup up unit on the inside, it was blowing hot air. After purchasing the advent air distribution unit without thermostat, everything runs smoothly. I love my unit. This my first time installing everything. I would buy again, if my second unit goes out. Great replacement for carrier unit.

Review from a similar Advent Air AC Unit in RV Air Conditioners


AIR CONDITIONER ARRIVED IN 3-4 DAYS AS EXPECTED. PACKAGE LOOKED TO BE IN GOOD SHAPE. UPS DIDN'T COPY MY NAME OVER TO THE SHIPPING ADDRESS, ONLY THE LOT #. HAD A RV REPAIR PERSON THAT DOES WORK IN THE CAMPGROUND INSTALL IT FOR ME. WE USED A LADDER AND ROPE TO SLIDE IT UP TO THE ROOF OF OUR 2003 CARRIAGE CAMEO 5TH WHEEL. ONE PERSON PUSHING IT UP AND ONE PULLING. IT WORKED VERY WELL. THE NEW ONE BOLTED DOWN AND HOOKED UP JUST LIKE IT SAID IN THE DIRECTIONS. TOOK A LITTLE BIT TO HOOK UP THE ADAPTER CABLES AND INSTALL THE EXTRA CAPCITOR FOR WE WERE REPLACING A CARRIER AIR V MODEL, BUT NO SERIOUS PROBLEMS. TOOK A TOTAL OF ABOUT TWO HOURS FOR TOTAL PROJECT. COULD HAVE DONE IT MYSELF IF I WASN'T HAVING A BACK PROBLEM. SEEMS TO RUN FINE EXCEPT FOR I WISH THE BLOWER WOULDN'T RUN ALL THE TIME, EVEN WHEN THE COMPRESSOR ISN'T RUNNING. MY OLD CARRIER DID THE SAME THING. I DON'T KNOW WHETHER THERE IS A WAY TO CHANGE THAT OR NOT. I DIDN'T TAKE ANY PICTURES WHILE INSTALLING IT BUT WILL TRY AND TAKE A PICTURE OF THE NEW ONE INSTALLED.


Comments
Seems to be good! i dont use it much in the summer but use it a lot in the winter down south. still would like it to shut off when the compressor isnt running.
