This AC unit replaces the Coleman Mach air conditioner on your RV or camper. Included adapter wiring kit enables the AC to work with your existing Coleman setup. Start capacitor jumpstarts the AC when camp power or generator power isn't enough.

Specs:
Note: The adapter wiring kit will not work on Coleman Mach 6000 or 7000 series ceiling vent assemblies made before 2006, and it will not work with any heat pump models.
This AC unit from Advent Air is designed to replace the old or broken Coleman Mach air conditioner on your RV or camper. The included adapter wiring kit ensures that the AC works seamlessly with your existing, in-good-working-order Coleman air distribution box and thermostat. 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.

Nice unit, easy install, had issues with hard start capacitor but e trailer sent a new one out
Very quick shipping and arrived as desc ribed.
I couldn't be more disappointed in this unit. I initially bought as an alternative to a 15k ducted Dometic unit that went bad and quit cooling in my 2018 Heartland Bighorn. The description at the time said it was a direct replacement and was 1/3 the price so I bought it. Like a lot of others, it showed up with a damaged cover. etrailer says they'll ship a new one when they get back in stock so that's no big deal. The issues began when I started the install. I got my old unit off the roof and the new one up. The footprint is considerably smaller so all the old mounting holes fell outside the gaskets area so I had holes to patch in my roof. The cutout size was exact, but there was no center divider to separate the return air from the supply air so I had to make one of those too. I went to hook up the wiring and, lo and behold, the control box wasn't included and wasn't compatible with my Dometic unit and there isn't an adapter available. Back to etrailer to order the control box I needed. Finally figured out how to rewire my camper to match the new box (again, no adapters or instructions are available) and found out my Dometic thermostat isn't compatible with the new control box. Finally sourced one from Amazon since etrailer doesn't sell it and got that installed a few days ago. Turned everything back on and it started to run. Checked all 3 fan speeds and everything seemed to be working good. It was 87 in the camper after sitting in the Spring sun of South Carolina all day. Let it run on high for an hour and a half and went back out to check on things. It had only dropped to 84 degrees! It's not even remotely hot outside yet. The air was coming out cool, just very little volume. If this is how it's going to be this thing is getting ripped back off and I'll bite the bullet and buy a Dometic again.
Long story summed up - compatible doesn't mean anything and upgrade is a complete lie. This is the first time I've truly been let down by etrailer.
The main problem with these units is the shipping container. This was the third unit that arrived damaged. UPS must have flipped the box over on its top and crushed the compressor terminal housing. The impact was hard enough for one of the terminal screws to punch a hole through the top cover of air conditioner. I waited weeks for this unit to be in stock again and now they want me to wait weeks more to get a replacement. as for the quality of the unit itself: unknown since I can't get a fully functional unit to install. Probably going with a Furion or Dometic at this point.
Advent 15000 BTU AC. Best price I could find on the internet or anywhere else for that matter. I received the unit 4 days earlier than expected which was a good thing. The installation, including getting it on the roof, was about 30 minutes. The Advent was a direct replacement for a 4/5-year-old Dometic Brisk II that quit cooling. The Advent is slightly quitter that the Dometic but of course that is only my subjective opinion. On low speed you can continue an intelligible conversation. The Advent has been installed 3 days now and it is working great.
I have purchased from etrailer in the past and have been completely satisfied. There are three concern/issues that need to be mention/address. (1) Packaging could have been better. The box it came in looked like it had been rolling around in the back of a UPS truck. (2) There was no installation instruction or owner’s manual whatsoever that came with the unit. I pulled mine off the internet. (3) the unit had minor damage on the base or main frame of the unit (I hope it does not cause issue later). The damage was not so bad as to cause forgoing the installation. Since the shipping box did not show any noticeable damage at the location of the damage on the unit, I can only assume that it was shipped by etrailer that way which is a QC issue.
The last 2 AC replacements I had to do I went with Advent instead of Dometic for several rteasons including quality and price. And etrailer has the very best customer service and prices around! Good AC at a good price with good service. What more could you asl for?
The unit was very easy to replace. The old unit was a 13,500 Btu Dometic. I was told (by etrailer) this unit would be a plug and play type since I had a previous Dometic system. Both units have the same wiring system, and they do. I simply unplugged the quick connect from old unit, removed the cooling sensor from the fins, removed the 4 bolts securing the unit to the RV, replaced the old unit with the new upgraded Advent #ACM150 15,000 Btu unit. Repeated the procedure in reverse with the new unit and the process was complete. I'm 'EXTREMELY PLEASED' with the new Advent unit and the ease of switching both units out. I Highly recommend 'etrailer' for Quick delivery Service, Reasonable Price and Professionalism. P.S. I apologize for not taking picture's /video of procedure.
Shipped quick , once was restocked, came in with small damages to outside shell and small dent on side, almost pinched copper line, should be packaged better from company for shipping (not an ETrailer issue)so far unit seems to be working better then the original (never worked) and replacement 13500 units that Camping World had put on trailer (took off another trailer) so I decided to buy my own to replace since no trust in Camping World and work performed

Extremely fast shipping and an easy install! I purchased this unit to replace my original Dometic unit that had been leaking Freon and the transition was flawless.
Even though it was a different brand from what we originally had on the top of our camper, the fit was an exact match. I had it installed within an hour. It is a quiet unit with more BTUs.
Have an 1999 Ford E-150 van used as an RV. I built a 30 amp box with 2-20 amp circuits several years ago. I and 3 doggies travel all over the SE for dog agility competitions. Loading and lifting a window A/C unit into the driver's side widow worked, but a major task. I cut and framed a hole in the van roof and installed the Advent ACM150. Had to install 12 volt system for thermostat and fish both 110 and 12 volt wire through walls and ceiling. A/C turned on perfectly the very first time I pushed the thermostat on button. Wowee...100 degrees outside; 69 degrees in the van. Absolutely life changing for me an my doggies. P.S. I am a nice 75 year old lady and still cannot believe I did this install all by myself. One year and miles later, this A/C is perfect!
Own a 2005 national seebreeze 8341 LX the rear a/c unit blower froze up. Called etrailer for a replacement unit.Bought the Advent air 13,500btu unit, great price, easy do it yourself install, plug and play. Wiring harness was correct, used the old hardware to tighten down the unit. Worked well with the Coleman thermostat. Happy camper
Other than having to remove the existing vent on my popup trailer, which was a bit difficult, the AC unit was easy to install right through the same hole. I had to wire up my own power cord, which didn't come with it, as this unit was primarily meant for RV's with wiring in the roof.
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.
Unit works great. Took an hour to change out. Hooked up as advertised. We replaced a Coleman Mach 3 13,500 btu for the 15,000. Puts out a lot of CFM.
Unfortunately, UPS shipping damage occurred in transit. Really nothing you can do about them being careless with your packages.
my order left etrailer within an hour of being placed. it arrived freight free 3 days later via ups. the ac was packaged very well and arrived without any visible damage. it is compatible with original thermostat and ceiling control box from a 2003 dometic 15000 btu duo therm . had to make a minor adjustment to the partition between the air chambers.the original ceiling plate was reusable as well.
When ordering this Advent with Carrier harness, I asked the sales rep 3 times to ensure it would replace a Carrier Unit that had a heat pump. Explained to her that the owner did not want a heat pump in the new unit, just A/C. Sales rep repeated that this was a direct replacement, just use the included harness and it would work with the Carrier Air Box and control board. Unit arrived and I removed Carrier and installed Advent unit. Wired in adapter harness. Unit would only run on Lo speed fan, no compressor, no Hi Fan. Spent 30 minutes troubleshooting Unit before calling ETRAILER for help. Different sales rep put me on hold and came back to say that there is a Tech Bulletin saying that it is not compatible with Carrier units that had a heat pump. Her only option given was to send me a shipping label to return the Advent unit. Told me that the rep I spoke with previously must have missed it. I suggested ordering a new air handler box and Thermostat to get the Advent working so my customer wouldn't have to pay me to do nothing but swap her old non-working Carrier back on the roof to block the 14" hole in the roof. Now waiting until mid June for a air handler as ETRAILER did not have any in stock. Morale of the story, don't use this on a Carrier that had a heat pump!
Great! Plug and play set up- took an hour at most- 91 degrees out and cooled down inside with in 30 minutes
One down one to go! Hardest part, getting AC on top but, managed no problem. E Trailer did good.
PROs
- easy to use
- modern looks
-low price
Cons
-delivers air only in one direction you must guess to assemble it in the roof.
-noisy
- cools after a prolonged time
-the cold air is directed through narrow openings, weird and not useful distribution,
-cannot direct the air where I need it.
still works like a champ, a year later! it was super easy to install, minimal tools you can find in a basic 'handyman' 20 piece set of tools. to get it on the roof i backed the truck up next to the rig and pushed the big box onto the roof from the bed of my truck. removal of the old one i had buddy stand in the bed of the truck as i pushed it SLOWLY off the roof to him.
Didn't realize I'd owned this unit for a year already, no regrets though. Works great, all you need to do is find a good helper to get it on the roof. About a half hour start to finish. Highly recommend as a replacement for original unit.
This was touted as being a direct replacement for the Dometic AC unit I had on my trailer... and that is EXACTLY what it was.. once I lined up the gasket with where my old AC was I only had to adjust it about 1/4 inch to get perfect alignment... the power plug goes in only one way so even I could install this. Whole process took about 45 mins for removal of the old system to immediately feeling the cold air as soon as I turned this one on. Would definitely do business with etrailer again.
