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.


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

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.

Great customer service, quality parts all at a great price. After seeing an unexpected delay on my order, I reached out to get an estimate on arrival due to a time crunch. I was informed exactly where the package was and when it would be “stocked” and sent out for delivery. Days later, I received a personal call with an update on it being received as “in stock” and out for delivery!

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


This was supposed to be a replacement for a Jayco 19h 2008 hybrid. I was told it would work fine with my ceiling control with the addition of a converter cable. This is a stretch at best. The holes for fastening the unit are 13 1/2 inches between. The holes in my old mounting plate are 12 1/2 inches. Thinking I needed to use the Advent ceiling unit, I ordered that. When I looked at that there was no way to make that fit. Back to using my old ceiling unit. Drilled new holes and then had to figure out air defection as the Advent doesn't match my old ceiling unit. Had to reroute the wires and build baffles out of foam and alum vent tape. Also installed start capacitor to make sure my trailer would handle the new unit. Had to call Advent to verify wiring connection for start capacitor. You should be creative and patient to install this unit yourself.

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


Great A.C. and perfect replacement for my Dometic unit that was 21 years old. Easy installation with all of the foam sealant in the right areas.
I would given etrailer five stars but there's two items they can improve on.
1. Better package and bubble wrap for the new roof unit. My cover was cracked on one side due to no secure wrapping.
2. A basic diagram of where to attach the old coolant coil sensor.
Last but not least Etrailer did it again with a affordable product and fast shipping. I'm in South Florida and my travel trailer is 60° in open sun with an out temperature of 95°.
Thanks guys for your outstanding customer service.

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


The unit is smaller than the unit I replaced and the fit was perfect at the access way. The Advent was plug and play with the Dometic harness and lower bezel. I couldn't be happier I had to look up torque specs for the gasket, as there were no instructions, but it was just a Google search (33-35 inch pounds)

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


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.

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


Finally received a month after I ordered the unit with that being said the installation wasn’t too bad however I had to do a little modification due to the 7 inch bolts being a quarter inch shy for my trailer but once I’ve got that figured out the rest was smooth sailing. So we’ll see what happens next Summer as the heat is now winding down.

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


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.

I hate to see this kind of damage! I passed your information along to customer service for them to better assist you.

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


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!

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


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.


Comments
Good:It’s still working great over this summer in 90+ degree weather. Bad: Heavy rain began entering the coach past the AC seal last month. Tightening up the four mounts had no help to the point of distorting the interior ceiling. I went to Ace Hardware and purchased 4 flat metal angle supports, three inches long on each side of the angle and placed them between the lip of the unit and ceiling to give additional strength to the ceiling. It was genius on my part. I was able to tighten the mounts more and stop the leak without distorting the ceiling and they were the perfect width and do not show. The seal had taken a set at the original compression point and I am afraid I will be required to retighten again in the future. Ugly: At some point soon I think the seal will need replacing and when I cross that bridge I hope there is one available and of better quality. The alternative may be using a recommended sealant between the seal and roof which will require loosening the mounts to wedges to open a space to allow sealant to flow between the seal and roof. Sealing on initial installation with sealant may not be a good idea by adding additional work a year or so after installation while on the road somewhere.

Yes the thermometer and plenum was the answer. The unit now operates as advertised and does well in bringing down and maintaining a cooler temperature. Happy Campers

Easy to install, straight swap for the old unit. It provided very good airflow to the front and back of the RV and cooled well also.
Actually didn't require the start capacitor to work with our Onan generator.
Product arrived with cosmetic damage.
Prepare the roof area and clear all debris (1)
Situate the upper unit and offer up the internal frame (2) Adjust position slightly if needed.
Carefully select the internal steel duct height to suit your roof thickness - shown in (3) un-compresssed.
Cinch down all four mounting bolts evenly to compress the foam gasket sufficiently without over-tightening (4)

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


Now don’t get me wrong; the air conditioner works great and cools perfectly! But this is supposed to be a straight hookup to dometic systems… yeah NO! Maybe dometic 1990’s but not 2010+ Dometic heat and cooling systems. The wiring is for old school dometic and we had to remove the control box off the original AC and install it on this new ac unit cutting all connects at the blower motor and compressor and wiring it into the old control board!!! This is insane…. Might as well of sent us a blower motor and compressor in a box all disassembled. If your dometic system is wired with telephone Jack’s DO NOT BUY THIS!!!


Comments
Yes, this 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.

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


So far so good. Unit installed in a couple hours AB’s is working well. Dometic duotherm failed so I ordered this one to replace it. Easy to remove old one and relatively easy to install new one.

The two challenges were getting the big heavy box on the roof and aligning the bolt holes between the air handler and the new a/c unit. I eventually got these done myself but would highly recommend you get a helper for those two portions of the job.

Another tip would be to run a screw into the ceiling on two corners of the air handler before you lift the old unit off. Mine wanted to fall out of the ceiling once I got roof unit off; that meant I had to try to hold the air handler up while repositioning the air conditioner from below by reaching up through the air handler. Had I secured air handler first it would have been much easier.

Install of the start capacitor was easy. Note: the start capacitor has two black wires that look the same except for the connectors are *slightly* different. The diagram says put black wire on common and then put black wire on the other terminal. And I couldn’t tell from the picture which connector went on each. I called an electrician friend and he says capacitors don’t have polarity, in other words it doesn’t matter which of the two wires goes to which terminal. I took his advice and all seems well.

One installed the unit itself puts out nice cold air. It’s a smaller footprint than my 15 year old dometic, but the past that mattered lined up perfectly. I think it’s about an inch taller also, maybe a little less. Just something to be aware of if you’re pushing the height limit on overpasses already :-)

I received this unit very quickly. Communication was outstanding. I knew when it was shipped and when to expect it.
Installation was very easy. 4 bolts and plug in wiring harness. The most difficult task was to get the unit on to the [email protected]!

Everything worked great except my old mounting bolts were 5/16 and these units require 1/4 so would recommend getting the bolts before installation 1/4 x7 are needed. But otherwise they work great! Love them!

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


Just finished installing this unit and it truly is a direct replacement for Dometic. I feel I got a fair price and shipping was fast. Taking off 1 star because the unit did arrive with a small dent along the base but this did not affect the install or function. Also, there was no install or warranty information included with the unit. Since this is the 2nd time I've had to replace the A/C on my RV, warranty info is kinda important.

    The only way to know if you have a Carrier or Dometic air conditioner is by looking at your air conditioner, which can certainly be a pain as it's on top of your trailer, but that's the only way to tell what you have. That said, the Advent air conditioners that will work as replacements are the same no matter if you have a Carrier or Dometic, the only difference will be if you need the Carrier adapter or not. You can choose from either 13,500 Btu or 15,000 Btu and if you want White or...

  • Can You Replace A Mach 8 AC With Another Brand Of AC Unit.
    The only difference between the mach 8 and the mach 10 is the height difference. So Yes you will be able to replace one with the other as long as the height change is not going to get in the way. Yes you can replace it with another brand of AC like the Advent Air Replacement RV Air Conditioner for Coleman Setup w/ Start Capacitor - 15,000 Btu - Black # ACCOL150B. You will just need to adjust the size of the opening with a trim kit. You will also need a Air Distribution Box w/ Built-In...

  • Can Heat Strip be Added to Advent Air AC For Coleman Set Up
    There is not a way to add a heat strip to the Advent Air Replacement RV Air Conditioner for Coleman Setup w/ Start Capacitor - 15,000 Btu - Black # ACCOL150B. The reason why is the Advent Heat Strip # ACMHD is controlled only by the Advent air distribution box, cannot be controlled by a thermostat, and simply allows AC's fan to blow air over the heat strip, as opposed to any type of temperature setting being available.

  • Recommended Replacement For A Coleman Mach 15,000 BTU RV AC System
    If you're wanting to completely replace your Coleman AC system in your Sprinter then I recommend the Advent Air RV Air Conditioner w/ Air Distribution Box, Start Capacitor, and Heat Strip # ACM150CH, or # ACM150BCH for black. This system comes with a heat strip to help warm up your camper, but I will say that add-ons like this heat strip or even a heat pump for that matter are more designed to take the chill off and not actually heat your camper like a furnace would.
