This Advent Air AC unit lets you replace an old or broken air conditioner on your RV or camper. It works with your existing Advent Air or Dometic air distribution box, and it is compatible with Coleman Mach or Carrier setups if used with an adapter wiring kit (ACCOLKIT, ACCARKIT - sold separately). 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. And everything you need in order to replace or add an AC unit is included, which makes installation simple and easy.

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 needed. Once installed, the hard plastic cover on the AC can easily be removed for maintenance and cleaning.

And in order to fully complete installation, this AC needs to be paired with your existing Advent Air, Dometic, Coleman Mach, or Carrier air distribution box and thermostat. Please note that an adapter wiring kit (sold separately) is needed if you are replacing a Coleman Mach or Carrier air conditioner.

Additional Accessories

Additional accessories can be purchased separately to improve the performance of your Advent Air AC unit. The start capacitor (ACMSCKIT) improves the performance of your AC by using stored energy to jumpstart it. And the electric heat strip (ACMHD) removes the chill on cold or frosty mornings in your RV, ensuring you stay comfortable. Please note that the heat strip will only work on Advent Air AC units.

Advent Air Warranty Coverage

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.

There were no instructions in the box. The unit itself looks good and I liked that the cover was well secured unlike the Dometic that’s it is replacing 12 screws versus 4.


great fit. Loud at inital start-uo but quieted down after a few seconds, works great


Excellent company to do business with! If you have a problem they are quick to respond.


I've ordered items before and was pleased with the quality. But this time, I was AMAZED at the speed of shipping. I ordered on Wednesday and it arrived the NEXT DAY!!!! INCREDIBLE, Great Job guys!






So EASY it aughta’ be CHEESY!!! Unboxed AC Unit, noticed two dents in the unit but none of the parts looked damaged or inconsistent; So I decided not to call regarding minor damage, instead I decided to install it by using two ramps I made out of scrap wood. TIP: the wooden ramps made it so simple to install the unit with minimal effort and two people. This made it a breeze to put in and I really recommend using this tip when installing your unit… The New Advent AC Unit made is so simple to plug into the dometic. This unit is made for easy installation and almost a universal fit. Great Experience at this establishment and happy with their product and selection of RV and Trailer parts. I will definitely recommend to all my fellow RV’ers! Happy Shopping! Always remember… Keep your library card updated!??????


I purchased this 15,000 BTU unit with the direction from customer service. I was told that it was a replacement for my original Dometic AC on my 5th wheel and that it would mount and have identical wiring.
They were very helpful and correct. It was extremely easy to replace. The mounting bolts and wiring hook up were identical to my old unit. The hardest part was getting it on the roof of my camper which actually wasn’t that difficult. I put an old piece of carpet (upside down) on the roof to protect it. I used my tractor with a front loader to lift it as high as I could then just set it up on the roof.
Once I removed the diverter/trim from the inside ceiling there are 4 bolts holding the unit in place, one wiring plug and the freeze sensor attached to the evaporator. Once that was all done it just lifted off the roof. After cleaning the roof where the old unit set, I simply set the new unit on the same seal footprint. I went inside hook up the wire plug, located the freeze sensor and tightened the 4 bolts. Don’t tighten the bolts too tight, just enough to hold it tight and adequately compress the foam seal.
The overall size of the new unit is shorter and smaller than the Dometic.


Item arrived damaged by UPS. I contacted etrailer & they are sending a replacement. Very good customer service. As you can looks like the unit was thrown around during shipping.


Changed out dometic 13,500 BtU conditioner with 15,000 BTU with Advent Air. The fit was exactly the same dimensions with the same plug for thermostat and other controls. All I had to reconnect was the 115v electric. When started it took about 30 seconds for fan ramp up to full speed and then compressor kicked in. Two people took two hours. One person had previous experience. Should work well cooling a 30ft fifth wheel camper.


So far so good, I ordered two of these to replace my existing units.
One unit arrived damaged, but is working OK.
They seem a little noiser than the Coleman Machs.
Working good so far.


We are very happy with our Etrailer purchase! We replaced our 13.5K BTU Dometic Brisk 2 with a comparable low-profile Advent unit. As we were not totally sure of which unit to purchase, we made a quick call into the call center to confirm compatibility. The call center was very friendly & helpful. We received our A/C unit in a timely manner with only 1 minor dent from the shipping process. This did not appear to compromise the unit's function, so we proceeded with the install. As many customers have noted previously, the hardest part of the installation was getting the unit onto the roof. Installing the provided start capacitor went smoothly and the unit fit our Coachmen Apex's measurements well. The plugs & wiring were compatible making the final change-over very easy. As noted in the unit's description, installation hardware is not included in the purchase but was not necessary, as our existing hardware fit precisely. Our new unit is better-looking & much more aerodynamic and compact. Best of all it is MUCH quieter & seems to cool very efficiently in our humid, Southern heat!! Etrailer saved us hundreds of dollars with this purchase, and we can't be more satisfied. Thank you Etrailer! :)
I included a photo of my husband's method of getting the unit onto the roof for your enjoyment.


AC works, however, the bottom half of the unit was bent, someone damaged (bent it) the bottom portion and must have put a new top cover on it and boxed the unit up. The box was in perfect shape.


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.


Bought this to replace an older (2007) Coleman 8000 on our pop-up. Had a bit of a time installing this. Please, READ THE INSTRUCTIONS and LOOK AT THE PICTURES. I had the upper duct that mounts to the roof unit installed 180 degrees off.

The converter kit that you buy with this if you're replacing a Coleman, didn't fit my Coleman panel. It's made for newer units. After talking to etrailer and the manufacturer I found I had to purchase a new control panel for inside. Another $85.

Overall it wasn't a bad job once I figured out the upper duct and the control panel issues. Unit cools well. About the same noise level as the old Coleman. It is not as thick top to bottom as the Coleman was. Think it's a little lighter after picking up both! Real test of how it works will be the trip we're taking next month.


have installed a few ac's over the years the smaller profile and weight as well as a simple plug and play made this advent a success in application . benefits over commercial dometic it replaced were quieter and less vibration as well as a general feeling of cooler throughout my 36 newmar .las vegas heat will continue to challenge the unit , we'll see if it survives the summer. so far pleased !


Replacing an aged Carrier Air 5. This unit was plug 'n play with the old controls ... as I didn't want to give up the old remote or worry about the furnace interface. Will was great on the phone and got me all I needed, plus follow-up on shipments. The new unit is a bit louder, but the air is cold.


The unit arrived, and I installed it the very next day. Overall, I spent about 2 hours preparing and completing the project, and the air conditioner works great.


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.


Puts out lots of cold air. No directions on how to matchup to a Coleman diversion box. Lots of DIY videos latter, some rigid insulation and duct tape and it works great. 100 degrees outside, and the AC is pushing 60-degree air inside. Easily keep inside temp at 72. Coleman Mach 1 could barely keep it at 80. Customer service has always been really friendly.


Just as stated. Replacement for my dometic. The installation was just as shown on video. Thanks to a son that has an auto crane. Great help for a 69 year old who thought about pulling it up an extension ladder.


This item did not arrive today. I ordered a package deal with the rv AC and the distribution ent with thermostat. Today I received the distribution vent with the thermostat. Why sell as a complete set with the item doesn’t ship together. On item came from Missouri and the other is coming from Utah. Installation was set for tomorrow but that is not going to happen. Funny thing is while ordering it stated it was in stock and would be arriving today. Just missing my AC unit. Not the best service from etrailer.


I don't know about longevity however I replaced 2 Dometic Brisk 2 systems on a camper I bought that needed a little more than tlc. It is a 2 zone Dometic system and these plugged right up. Only had them in a for a few days but they work great! Very pleased. I am hoping they last. Shipping was FAST and Etrailer kept me up to date on status. They were also very helpful with questions I had to make sure they would work with my system. I think these are actually quieter than the Dometics I replaced. Not hard to install, in fact the hardest part was getting them on the roof.

  • What Distribution Box Is Required When Installing The Advent Low Profile AC In a New Opening?
    As you are adding the Advent Air Low Profile RV Air Conditioner # ADV89FR to an opening on your RV which did not already have an AC you will need to select from one of the 2 options. First is the manually controlled Air Distribution Box # ACDB. This has the manual dial you will switch on and off as needed. The other option is the Air Distribution Box w/ Wall-Mounted Thermostat # ACRG15. This is typically more convenient and necessary on taller campers where you cannot easily reach the ceiling...

  • Replacement for Carrier AC Unit 68RV14102A
    Hi Deb; if you order the Advent Air RV Air Conditioner # ACM135B along with the Carrier Adapter Wiring Kit # ACCARKIT you won't need anything else. This AC unit will plug directly into your Carrier setup so you can use your old Carrier ceiling vent and thermostat. It is also available in white # ACM135 if you would prefer that over black or you could use the low profile models # ADV79FR or # ADV89FR

  • Does The Air Distribution Box And Heat Strip Come With The Advent Air Low Profile Unit # ADV89FR
    Hey Larry, The Advent Air Low Profile RV Air Conditioner # ADV89FR is just the rooftop unit. If you're needing the complete system then you'll want the # ASA36YR to get the heat strip and an air distribution box with the controls built into it. If you're wanting a wall thermostat then you'd need part # ASA89YR along with the heat strip # ACMHD instead.

  • How to Determine if Advent Air Low Profile Air Conditioner Will Work on RV
    Hello Cori, It is possible you can use the Advent Air Low Profile RV Air Conditioner # ADV89FR on your RV, but we don't have any way of knowing what is on any specific RV to determine compatibility. First, if your current air conditioner has the control box built into the existing AC unit, then the # ADV89FR won't work as a replacement. Other than that, do you have an Advent Air or Dometic set up? If so, this unit will work. If you have a Carrier AC then it will work with Adapter Wiring...

We have Advent units available in both 13,500 BTU and 15,000 BTU depending on your needs. Here is what I recommend: 13,500 BTU - Advent Air Low Profile RV Air Conditioner - 13,500...

  • Do I Need a 15,000 BTU or 13,500 BTU AC System for a Enclosed Trailer?
    There is a formula to determine how much BTU is needed for a trailer. You will want to take the total square footage and multiply it by 20 and that's the minimum BTU you will need. The 15,000 BTU Furrion Chill HE RV Air Conditioner System item # FR23PV in black or item # FR55PV in white you were looking at would be a great choice. They're not consider low profile units like item # ADV89FR but they're not too much larger and the Furrion's come with everything you'll need. Our low profile...
