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.

When I ordered a rooftop ac, I was informed it may take up to 3 months for delivery. I rec'd the ac in less than 3 weeks so was extremely satisfied. 3 of us installed which went very smoothly all within 45 minutes. The ac has been working fine ever since. Also etrailer's price was a 1/3 less than [outdoors store]

- ACM150

Excellent company easy to warranty straight forward service only warranty one out of 40 they where quick to respond and replaced unit great product superior to Dometic in my opinion or Coleman and I’ve been reporting Rv’s for 20 years you can trust the advent 15 k unit deliver text book cold temp here I redid g California it is 117 regularly in summer we carry these and only in I. 15k white if it a Coleman we add the adapter cord sold here at etrailer can’t say enough Einstein’s mobile Rv Redding California thanks etrailer your a great vendor

- ACM150

Great value and works very efficiently on our camper.

- ACM150

Sir's, I purchased the replacement rooftop unit and installed it for my girlfriend, as best as we can tell the unit is working as it was designed to, though my girlfriend did say it seemed to be a bit noisier than the old unit. Thats the only thing she has had to say, that it does cool good in the living room area. Thank you for Ur following up e-mail , Rick Hardman

- ACM150

No problems...I wish someone would have mentioned how easy it was to install. I felt violated after watching it being installed and paying $400 bucks.

- ACM150

I found a little dent on it but Nothing was hurt , I can Not tell you just how easy it was to install it, as you said plug and play, l am VERY Happy with the service you gave me! THANK YOU! I’ll be telling everyone about the service and quickness of you!

- ACM150

Seems like a great product so far. Installation was simple and it cools a 8.5x28’ trailer easy. One note: you must have 120v and 12v supply for this AC to work. I did not know that and had to go through some extra trouble of running 12 V power source.

- ACM150

The a/c seems fine except for the 2 corners in the shroud (it was mentioned). The only little problem is the motor inside was off the center following a probable drop. I managed to align it as it is supposed to. The unit is running fine.

Was a direct replacement for the dometic 13,500 unit that went out. I would highly recommend upgrading to the 15,000 BTU

- ACM150

Perfect fit. Arrived 2 days ahead of schedule. I was able to install it in under 2 hours.

- ACM150

The CSR Brandi was very pleasant and knowledgeable regarding the A/C replacement that I needed and the additional items needed to complete the repair. I highly recommend Brandi's CSR services and this company.

- ACM150

Arrived a day earlier than expected and in good condition.

I am surprised by the missing inside grill cover. I thought the AC unit would come with a new trim cover for the inside. I used the old one and it doesn’t fit correctly so it’s just hanging there. Does this AC not come with a trim cover for the inside?

This unit does not come with the Air Distribution Box included with the Air Conditioner. If you were looking for a unit with the air distribution, part # ACM150C
Advent Air RV Air Conditioner w/ Air Distribution Box and Start Capacitor - 15,000 Btu - White
comes with the Air Distribution Box. Advent Air does sell the boxes separately depending on what type of thermostat you have. Part # ACRG15
Air Distribution Box w/ Wall-Mounted Thermostat for Advent Air RV Air Conditioners - White
is for wall-mounted thermostats. Part # ACDB
Air Distribution Box w/ Built-In Thermostat for Advent Air RV Air Conditioners - White
is for unites with built in thermostats.

Added as a second unit to a 33' Crossroads. Works great. Easy straight forward install. Using the ACRG 15 air distribution box with thermostat. All the wires are labeled from the factory so installation was a snap. Added the ACMHD heat strip also but it's 85 degrees and a little hard to test that out just yet. The crew at etrailer were great at helping me get everything picked out that I needed. Shipping was fast. If there was such a thing as a 10 star rating, they deserve it

- ACM150

fast shipping . item was as described . so far im very pleased and will shop here in the future.

- ACM150

Replaced a Carrier AC with this Advent. Was not famliar familiar with Advent but based on ratings decided to try it.With the adapter kit,it was a seamless replacement. Just as quiet,or quieter.Moves as much air. Only been installed a few days, so obviously don't know about longetivity. Your staff was great to deal with regarding shipping etc. during covid-19. Thank you.

- ACM150

We have purchased 5 of these now and they are all in great new condition and the shipping was quick and arrived perfect. Great A/C for our clients.

- ACM150

Easiest repair I’ve ever done! Four bolts and a quick connect to the power. I was pairing to the dometic air distribution box! I would buy this company 10 time over!

- ACM150

works great

- ACM150

This is a direct replacement for a unit that I have. A tree branch put a hole in the condenser. This was not the fault of the unit. I was able to remove the six Phillips head screws on the inside shroud, unplug two cables and remove four 10mm bolts, then remove the old unit. once the old unit was out of the way place the new unit in place and reverse the process. I think the whole process took me 30 minutes to complete. It works just as well as any other unit I have owned.

- ACM150

Perfect unit less than a hour to hook up and running blows very cold air thank you etrailers for the greatest service

- ACM150

Still working like a gem, one year late r!

- ACM150

I bought this for a 1983 ford shasta r/v Took about 1 1/2 hours to install. would have been less time but I had to reroute the 12/2/ rx to the other side. Was very easy to install. So next time I hit a very low tree branch and rip off my a/c unit I will get another one here!!!

- ACM150

Good product but lacks clear instructions. Bought mine with thermostat but no spare cable to connect the 2 units

- ACM150

Top cover is broke at the screw holes.
