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

Advent Air AC Installation 13,500 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 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.

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.

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!




by:

Jury out on this one. I finally received the unit and it came with only minor shipping damage. I have yet to install the unit and the instructions are calling for a piece to be removed which is not removable. Will see.


Comments
This kit is designed to replace the Coleman upper unit only. It will utilize the installed Coleman control system. This kit is designed to work with common Coleman models, but should not be considered universal.
-- Etrailer Expert Katrina B - 03/25/2022


by:

The unit seems to be a top of the line quality product. Installation was fairly straight forward except the instructions are outdated. Instructions tell you to remove the receiver cover to prep it for mounting the Coleman control panel. The cover is not removable, it's now a high density foam. Also the supplied hardware is not long enough to go through the cover. The photos in the instructions are very hard to determine what they are of.


Comments
Labor Day weekend 2018 we were camping at a site in direct sunlight. While running the unit on high we experienced a smell of something electrical over heating. I feel that the compressor failed. I have been in touch with the company and have the location of the nearest service location but have not been able to take the RV there yet. There is a 2 year warrantee so it shouldnt be a problem just an inconvenience.

by:

Great unit, I was not aware it didn't come with the air distribution box so I had to order it separately. If I did it again I would have bought the complete package I found after a little more research.




by:

Now that I have installed it. Well designed product. Start capacitor modification took about 10 minutes. Trans=locating the old control box took longer than expected as the trailer control wires and romex power cable were not long enough. Mounting it lower in the evaporator housing worked. The long (4 ea) through the roof mounting bolts are spaced farther apart than Coleman's configuration and take up the whole roof-top opening. Everything is working in all modes.




by:

Ahoy folks.
Yelp I ordered and
received ACCOL135 unit. designed to replace a Coleman unit.
product was delivered from out of state, right on time!! very cost effective.
easy installation. preformes as advertised. longevity undetermined?




by:

It works fine mostly plastic and styrofoam and noisy and this is comparing it to the Coleman Mach 3 that I replaced last year on the bedroom on my motor home and this one on the living room of same motor home.




by:

Very pleased with the purchase, perfect fit. Thanks for checking up on it.

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


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.

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!

simple install, make sure to prep around ducting with foil tape to seal good and decrease loss of cool air escaping. Plug and play install, blows harder than the dometic it replaced on my motorhome.

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


The AC blew up before I had a chance to install the Start Capacitor, I had to buy a Furrion kit from [online].. Not sure what happened the AC had a little cosmetic damage when I received it, the cover had a small crack and the metal base had a little dent, I was able to fix with a little tape and pull the dent out by hand. With all the hassle of getting a SC delivered being full time RVrs it wasn't worth the time to exchange it, well it literally blew up after about 1 1/2 months use.


Comments
Wow, I am sorry to hear about what happened with the AC unit. It definitely should not have blown up like that. Our customer service team will reach out to assist you.

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


Super fast shipping, great price, very helpful staff. Installation was super easy. Replaced one of my original 1998 Duo Therm units with this unit. Getting the old unit unstuck was a bit of a challenge but from there it was just a matter of getting it lined up with the hole, attaching the cold control, putting the 4 bolts in, plugging it into the original connector, putting the plastic cover plate back on and turning it on! From experience I know that even the simplest of projects on an rv can snowball into a major ordeal. Without a doubt this was one of the easiest and most straightforward projects I’ve tackled. Working in 95° Oklahoma heat start to finish was under two hours and that included replacing the old foil sealing tape around the air duct. Having two strong people on top while I was inside to get it centered over the hole, getting the old unit down and the new unit up was a huge asset! I’ll be replacing the other unit sometime over the winter for sure. Just can’t think of anything negative about the whole experience.

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


It is a very good unit. I works really well. Was very simple to install and get it running. Will recommend that anyone buying this also buy the Starter kit ACMSCKIT to. it will make it so much easier on the unit and will help with the surge every time the kicks on.

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


The AC I ordered was exactly what I needed. Installation was not too difficult. The only issue I had was reconnecting the thermostat in the control panel. But I know now, that I should have taken a picture before disconnecting the wires. My husband installed the rooftop unit and I helped him with the wiring.
Installation took 1.5 hours total.

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


Over all this is a good unit and met expections. The unit installed as stated with the existing wiring harness and mount. The overall dimensions of this unit are approximately 3 inches longer than the Dometic that it replaced (e.g. if you have a limited space due to solar panels as I do check carefully). The start Capacitor worked as intended and the start load was measure at 15.1 amps inrush. The running unit measured 14.7 amps with fan on high. The split (temperature between the return and the supply air) measured 25 degrees F and was consistent. The only negative is that unit will only run on two fan speeds with the existing Dometic thermostat not the three it is capable of.

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


I called etrailer and gave them my model number of both the roof unit and the interior air distribution box before I ordered and the "Expert" told me that this unit would work and would be plug and play with my existing unit in my camper. I ordered it and the roof unit did indeed work great. It bolted right up and my existing control box works great. The inside air distribution panel not so much. Called the etrailer "Expert" who then called the manufacturer who said basically oh well it happens. So my only option was to buy a complete retrofit kit that has the interior panel and a whole new thermostat set up that I don't need or want for an additional $xxx. I asked etrailer for a little help supporting their customer and at least give it to me for the price I would have gotten it for if I ordered it as a kit with my roof unit which would have been $xx. I think they should have sent it to me for free but a fair compromise would have been the $xx price because they were the ones that told me not to buy the kit in the first place because it was "plug and play". But all etrailer cares about is making that next sale and the next buck so they made me buy it for full price. So make sure that whatever you order from etrailer is going to work and verify their advice with another source before you buy because once you give them your money you are on your own. etrailer will not even try to make it right. It will be a long time before I buy anything from etrailer again and if anyone asks I will send them somewhere else.

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


Installing was quick and efficient. At first when I hookup up unit on the inside, it was blowing hot air. After purchasing the advent air distribution unit without thermostat, everything runs smoothly. I love my unit. This my first time installing everything. I would buy again, if my second unit goes out. Great replacement for carrier unit.




by:

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


This was a replacement for a Carrier V 15,000 roof top. Still using the Carrier control panel and ducting. Runs and cools good but cycles more than our older advent air 13k ductless in the bedroom. Cycling may be caused by the ducting instead of ductless. It is quieter than the old Carrier V and seems to cool the same.




by:

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


I would like to thank George for his help when I needed it. In the year using my Advent air conditioner, it has done very well. For a DIY it was a straightforward install, and I only needed someone to help me get it on top of the RV, (in the box as someone suggested). I hope to get many years of service from my Advent air conditioner
