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.

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.

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.

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


I have tried to get this thing to run for over a year now. I'm on the third thermostat, I've checked the 12V voltage and the 110 voltage and both are good. I've wired it as per the manual and it still will not run. It will start, but will not continue running. I get an E5 code which is a communications error between the thermostat and control box or low voltage. Followed up on both and still not finding the problem. Nothing I try seems to work. My next move is to return it on warranty. I'll let you know how that goes. Right now I'm not a happy camper (pun intended).


Comments
The best way to troubleshoot the issue is to have a technician come take a look. If you would like to talk through the error code with the manufacturer their number is 800-688-3135.

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


AIR CONDITIONER ARRIVED IN 3-4 DAYS AS EXPECTED. PACKAGE LOOKED TO BE IN GOOD SHAPE. UPS DIDN'T COPY MY NAME OVER TO THE SHIPPING ADDRESS, ONLY THE LOT #. HAD A RV REPAIR PERSON THAT DOES WORK IN THE CAMPGROUND INSTALL IT FOR ME. WE USED A LADDER AND ROPE TO SLIDE IT UP TO THE ROOF OF OUR 2003 CARRIAGE CAMEO 5TH WHEEL. ONE PERSON PUSHING IT UP AND ONE PULLING. IT WORKED VERY WELL. THE NEW ONE BOLTED DOWN AND HOOKED UP JUST LIKE IT SAID IN THE DIRECTIONS. TOOK A LITTLE BIT TO HOOK UP THE ADAPTER CABLES AND INSTALL THE EXTRA CAPCITOR FOR WE WERE REPLACING A CARRIER AIR V MODEL, BUT NO SERIOUS PROBLEMS. TOOK A TOTAL OF ABOUT TWO HOURS FOR TOTAL PROJECT. COULD HAVE DONE IT MYSELF IF I WASN'T HAVING A BACK PROBLEM. SEEMS TO RUN FINE EXCEPT FOR I WISH THE BLOWER WOULDN'T RUN ALL THE TIME, EVEN WHEN THE COMPRESSOR ISN'T RUNNING. MY OLD CARRIER DID THE SAME THING. I DON'T KNOW WHETHER THERE IS A WAY TO CHANGE THAT OR NOT. I DIDN'T TAKE ANY PICTURES WHILE INSTALLING IT BUT WILL TRY AND TAKE A PICTURE OF THE NEW ONE INSTALLED.


Comments
Seems to be good! i dont use it much in the summer but use it a lot in the winter down south. still would like it to shut off when the compressor isnt running.

Had to order a new upper unit, my old one would not cool. New one came in 6 days. my son and I installed new unit, the worse part was getting it up on the roof. After that it was smooth sailing! The new advent replacement works well! very cold! came in good condition also,no dents or scratches!! price was right. Would order from etrailer again!!

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


It has been about a year since I installed these units. They have been working good with no issues. The installation was easy. Had to have an adapter harness to change from the older ac units. The opening was slightly different, but got it to fit with minor modification of the mounting ring.

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


I really debated about buying and installing a replacement AC unit ourselves or having a local RV dealer do it for us. After a lot of research, including reading etrailer's great on-line Q&A section, we ordered the Advent Replacement AC with the Coleman set up w/start capacitor. The wiring, which was my main concern for doing it ourselves, was truly "plug and play" and matched the old unit perfectly. No new control box or air distribution cover needed. The worst part of the entire process was getting the old, much heavier unit to the ground. The new unit fired right up and started cooling the toy hauler in the 113 degrees Las Vegas heat whereas the old unit was pretty much maxed out once we got past 90 degrees.

We are very happy with the Roof top air conditioner we purchased for our RV. Thank you Tommy for advising us to get the start capacitor also. It was a great recommendation. Installation was a breeze. Having the extra AC has been great keeping us cool on these really hot almost 100 degree summer days. Thank you e-trailer.

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


Unit fit well. Instructions were pretty clear. It would have been nice to know that the Advent did not come with control unit. Fortunately the old one was not damaged or I would not have been able to install. The Advent unit is smaller than the Coleman-Mach and somewhat louder. Otherwise is cooling well at this point.

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


Approximately one year ago during one of the hottest days of the year our roof top hvac unit in our 31ft motor coach bit the dust. Note; The unit was original so it didn't owe us anything. After doing some research online and reading many reviews I elected to order my replacement from etrailer.com mainly because they appeared to be a professional company that knows how to treat a customer. In addition I did have a few questions after I installed it and a technician was very helpful to clarify a few things. I also ordered the back up heat strips later and installed them as well. We used the unit over the summer of 2020 as well as the cold winter period and It seems to provide adequate cooling and heating. I would recommend using this company (etrailer) as well as the 13,500 BTU Advent RV Air Conditioner. We're happy campers..!

One little issue with the shroud around the condenser was rubbing and causing a lot of noise. Not a big deal. Trimmed with a utility knife and all good. It also is not exactly plug and play. It takes some trouble shooting to get the wiring correct with the furnace and AC to work with the thermostat

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

I've been extremely pleased with this 15k BTU unit. I replaced two Mach units with two of these, and they've run strong and hard under some pretty significant Arizona heat. You can't beat the price at all. Super easy change-out. Absolutely 10/10 would recommend.

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


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.

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


Air conditioner works very well. Have owned the unit for over one year. Only reason for 4 stars instead of 5 is that there’s has been a few times where the unit stopped working and we have had to turn it off and back on to get it restarted. Other than that it has worked very well.
