Is this right for you? Product Expert Kathleen M says:

Yes, if you:

  • Have an RV or trailer that is sectioned off or has air ducts that work best when there's lots of air movement
  • Prefer a black cover on the AC to match your RV

No, if you:

  • Are adding an AC where one didn't exist before or as a 2nd unit to boost cooling in an RV
  • Use a generator and want a start capacitor to make sure the AC never has trouble firing up
This AC unit lets you replace an existing AC or add a new AC to your RV or camper. It works with your existing Advent Air, Dometic, Coleman Mach, or Carrier air distribution box and thermostat - adapter wiring kit (sold separately) may be required.

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

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.

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.

Got lost on the way, shipping companies fault, no blame to etrailer. Arrived in good condition and blowers cold air!

This unit replaced our Dometic A/C with the CCC2 thermostat. The Advent harness plunged directly into the power supply. The only thing I did extra was took off the old outside temp sensor on the Dometic and placed it on the Advent unit. We were receiving an E4 error on the thermostat until I did that. So far so good. 90deg outside and we keep it at 75 with no problems. Only time will tell.

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


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


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.

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.

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!!

Its been a year and the air conditioner still works great! Cools the trailer even in 90 Degree days! Would purchase again!

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


The Advent brand was recommended to us by several mobile RV repair people. Selecting the right unit was made even easier by the descriptors etrailer used. Installation was very simple and we had the old uninstalled and new installed in under 30 minutes. This unit is even quieter than the Dometic it replaced. Item was delivered within days of ordering. Easy breezy.

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


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]

  • Replace 13,500 BTU Advent with 15,000 BTU Air Conditioner
    If you installed a start capacitor, such as # ACMSCKIT or # SSR54FR or similar component, and having proper operation afterwards but then at a later point the unit operates without blowing cold air, I would not associate the installation of capacitor with current malfunction. I suggest you first ensure proper air flow around all AC components, if this has been in storage there may very well be debris blocking air movement and proper operation. Yes you can replace a 13,500 btu unit...

  • Will the Advent Air Replacement RV Air Conditioner Work with a Ducted System
    The Advent Air Replacement RV Air Conditioner part # ACM150B is just an overhead unit, it can be used with either a non-ducted or ducted setup. This is determined by the distribution box installed which attaches to the bottom of the unit, inside the trailer. The Air Distribution Box w/ Wall-Mounted Thermostat for Advent Air RV Air Conditioners part # ACRG15 is compatible with a ducted system and works with the Advent Air Replacement RV Air Conditioner.

  • Powering the Advent Air RV Air Conditioner
    Attempting to operating the 15,000 Btu Advent Air RV Air Conditioner, # ACM150B on a 15 amp outlet is not advisable. The unit will draw about 15 amps while operating and likely draw greater than that for start up it would also prevent any other items from being operated on the same circuit, even if it did not trip the breaker during start up. It is always advisable to connect the RV's AC unit directly to the distribution panel on its own breaker.

  • Replacement AC Unit for 1994 National RV Motorhome with Dual AC Units
    The Advent Air Replacement Rooftop RV Air Conditioner for Dometic Setup - 15,000 Btu - Black # ACDOM150B is what you will want as a replacement because it comes with the start capacitor so you will be able to run both units. The start power is usually what keeps people from running both units, but if you replace both units with these then you won't have any issue. When you are able to run both units, you can absolutely go with the 13,500 btu unit instead. I recommend the Advent...
