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 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.

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!


Great service just received the product. However the product was slightly damaged in shipment. Have pictures where do I send them? No damage to shipping box.

Thank you for letting us know. I have sent your information along to our customer service team.

I don't know if you really want me to you lied to me right off the bench saying these plug right in plug and Play I just didn't happen I'd spend $XX for a pigtail get it plugged in and it's still it doesn't work right with the automatic air it might work good with switch air on and off but climate control with the Vance please don't sell it to another one like that cuz it doesn't work right thank you

This AC unit can be paired with with an Advent Air or Dometic set up without needed a conversion kit. If replacing a Coleman Mach or Carrier set you will need the additional wiring kit. If it is a Coleman Mach you will need part # ACCOLKIT
Coleman Mach Adapter Wiring Kit for Advent Air RV Air Conditioners
and if it is a Carrier then you would need part # ACCARKIT
Carrier Adapter Wiring Kit for Advent Air RV Air Conditioners

The a/c unit installed very easy. The only issue I had is that the package was slightly damaged during shipping. The plastic cover was cracked. Nothing a little Gorrila glue couldn't fix. Once I installed the coil freeze sensor in the correct place, the unit works great. Thanks.


Best rooftop RV airconditioner I’ve ever had. We have had a bery hot summer in North Texas and I jave stayed cool and comfy!


Etrailer has excellent pricing and shipping. Product is ok blower not perfectly round little noisy but over all works excellent and was plug and play take 1.5 hours to install with clean up and proper prep.


We installed the AC Unit, used it for 3 months in South Padre TX during Jan/Feb/Mar 2022, put the RV in storage in April 2022 pulled it out in July 2022 and the until only blows recirculated air not cooling at all.

That should not have happened! This is still under warranty. We will reach out with the details.
-- Etrailer Expert Sierra K - 07/19/2022


I ordered six of these units and very nicely asked customer service to double box them, as they have done before, because of freight or shipping company beats them up. I’m constantly having to return them and I lose money and time do not care


Perfect fit to replace a dometic RV AC that had failed on my rv. The install was very simple and the delivery was quick.


It is a very quite unit and works great.

wasn’t exactly plug and play it took some wireing to get all the functions to work with my Keystone camper, but the remote works as it should.


Super simple install. The hardest thing was getting it on the roof and the old one down. Simple plug and play. If you're at all mechanical you don't need to pay to replace your A/C unit. 6 screws to remove the inside cover, 4 bolts holding the unit to the roof, one main plug and a sensor wire. The sensor was just jambed into the factory condensor. The new unit actually had a clip in it for the sensor. I highley recommend this unit. Works great. We had a 100 degree day and the trailer stayed at 78 all day long.


Excellent replacement for an old Dometic unit, exact fit, easy to install. Works well, keeps my camper nice and cool.


I received the unit as promised. I installed the start capacitor. Very Easy. Good instructions.
Hardest part was swapping the units on/off roof!!
I would say it took me a total of 45 minutes to change.
It is 91 here in AZ. The unit is putting out 48.8 degree temperature.
VERY VERY HAPPY with the whole process and end results!!
I will be replacing my second unit soon……


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]


Was advertised as plug n play,NOT. Not until you you purchase a plug adapter for another 55 dollars.

We do have it listed in the description that an adapter wiring kit would be needed if you have a Coleman Mach or a Carrier set up. The wiring kit for the Coleman Mach would be part # ACCOLKIT
Coleman Mach Adapter Wiring Kit for Advent Air RV Air Conditioners
and the wiring kit for the Carrier system would be part # ACCARKIT
Carrier Adapter Wiring Kit for Advent Air RV Air Conditioners
-- Etrailer Expert Jenny N - 03/29/2022
Will that also require the heat strip
-- comment by: Martin - 03/30/2022
You can add a heat strip to the AC unit. It is part # ACMHD
Electric Heat Strip for Advent Air RV Air Conditioners - 5,500 BTU
-- Etrailer Expert Jenny N - 03/30/2022


I received the order a week early. Only issue is that the frame was damaged in shipment but was isolated to the frame and no other damage. Installation was straight forward. Installed on 7x14 trailer. Hardest part was removing vent opening sealant from the roof. Ran fine on initial start-up. Will test with heat load today.


it was fast delivery very easy installation and it works perfectly


As much lighter than the old carrier unit. Uses less power. Was easy to install


Had what I needed and they verified that everything was correct and match up during installation. Good price too.


Service was excellent, tracking very good and both ACs showed up in excellent condition.


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


Don't know yet haven't installed it yet


Install was a bit more than I had anticipated, however, once I had the adapter in hand it works very well.


Delivery was left on its side. AC need to be right side up and the box said it.


Went I have installed and working Ill gave my calcification now is no done yet

  • Recommended RV Rooftop AC Unit with Ceiling Vent and Controls
    Great question. We do have the Advent Air Rooftop RV Air Conditioner # ACM150 with the interior components. It is part # ACM150C and it also includes the start capacitor. That capacitor is extremely helpful in making sure you can start your AC even when the shore power isn't able to draw that capacity. The capacitor will automatically refill to ensure you never have an issue starting your AC. The vent assembly has a built in thermostat to control fan settings and temperature. There...

  • Replacement Advent Air Conditioner With Ducted RV System
    The 15,000 Btu Advent Air RV Air Conditioner part # ACM150 will work well to replace your ducted Advent Air conditioner. It has a 1-year warranty.

This is just the air conditioner unit and will use the existing ducts in your trailer. I have attached an installation video for your reference.

  • Compatibility Between 2002 Keystone Cougar & Advent Air RV Air Conditioner
    What is meant by, "The only compatibility you would need to verify would be between the upper unit and the ceiling assembly." is that you will just have to make sure the measurement of the Advent Air RV Air Conditioner # ACM150 line up with the existing ceiling assembly. The # ACM150 fits in RV units that have a roof opening size of 14-1/4" long x 14-1/4". As long as these measurements line up with your 2002 Keystone Cougar the unit will fit.

  • Recommended Replacement Rooftop RV Air Conditioner For A Dometic Unit In A 2015 Mountaineer RV
    I just reached out to my contact at the manufacturer ASA Electronics, and I was advised that as long as the Dometic is using their 6 pin connector between the upper unit and ceiling assembly, the # ACM150 will sit on top in place of the existing upper unit. The only compatibility you would need to verify would be between the upper unit and the ceiling assembly. So as long as the Dometic uses the 6 pin connector, the ACM150 will sit on top of your existing setup.

  • Weight of the Advent Air Rooftop RV Air Conditioner # ACM150
    The Advent Air Rooftop RV Air Conditioner # ACM150 is still fairly new to the AC scene which is why it doesn't have very many reviews. With that being said, we haven't really had much customer feedback as of yet (March 2018). It does weigh less (68 lbs) than the Coleman units which is an attractive quality. The 6 foam pads and 6 fan blade help to really quiet the AC unit while providing you with quite a lot of power. The condensation dispersion cooling system uses the excess water in the...

    There should be a sticker with some info on the underside of your Advent AC unit. If you check out the picture of the bottom of the Advent Air RV Air Conditioner # ACM150 you can see where the sticker is located and I highlighted where you'll find the part/model number on the sticker.

  • Does the Advent Air RV Roof Air Conditioner ACM150 Come with a Wiring Harness for Installation
    The Advent Air RV Air Conditioner - 15,000 Btu - White # ACM150 comes with a wiring harness and all hardware needed for installation, so you won't need any additional parts when installing this. Since it is a 15000 BTU unit like the Dometic 59516.501 it will be a great replacement option. I've linked the installation video of this unit for you to have a look at, as well.

  • What Wattage Demands Does Advent Air 15k BTU AC Unit Require
    We've checked with Advent in the past and to run the Advent Air AC unit part # ACM150 you'd need a generator with at least 3,000 watts. If you installed this on your trailer where there wasn't a unit there prior and it's working fine I would not worry about what you mentioned as far as it not being good for an install where a unit wasn't. The amperage draw for this is 20 amps at startup.

  • Can I Replace The Advent AC135 With The Advent ACM150
    Yes, I spoke to a representative from ASA Electronics, Advent's parent company. You can go from the Advent AC135 to the Advent Air RV Air Conditioner - 15,000 Btu - White, part # ACM150. You should be able to plug in this new unit since your RV was wired for the old unit. Depending on your roof there may be some minimal alterations that have to be done for the unit to fit. I have included an installation video link below.

  • Advent AC ACM150 Cuts Off
    Thank you for your purchase from etrailer of the Advent Air RV Air Conditioner # ACM150. What is happening is called short cycling and there are a couple of reasons why that might happen. Most often, the issue is with the thermostat reading the temperature incorrectly, maybe due to air blowing at the thermostat. When the thermostat senses cold air, it will turn on and off quickly - short cycling. If you can re-direct the air to not blow right on or near the thermostat that may resolve the...

  • Troubleshooting An Advent Air RV Air Conditioner That's Leaking Water Into The Trailer
    If your brand new Advent Air RV Air Conditioner # ACM150 is already leaking into the trailer then there could only be two causes: 1. The gasket isn't properly set and is allowing the water that is draining onto the roof to seep back in. 2. Something is preventing the water from leaking out of the drain pan onto the roof and allowing it to build up enough to pour back inside or there's a manufacturer defect in the drain pan that's allowing the water to drip right in.
