This Advent Air AC unit lets you replace an existing, old or broken air conditioner or add a new air conditioner to an area on your RV or camper that doesn't already have one. 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. For your convenience, the included air distribution box has a built-in thermostat that lets you set the fan speed and temperature. 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 or add an AC unit is included, which makes installation simple and easy.


Air Distribution Box and Thermostat

Advent Air Air Distribution Box

The AC unit includes an air distribution box with a built-in thermostat. The dial on the left controls the 3 cool settings and the 3 fan speed settings, which let you increase or decrease the airflow. If you add an electric heat strip (sold separately) to remove the chill on cold mornings, then the dial also controls the heat setting. The dial on the right allows you to set the temperature. Additionally, there are adjustable registers on the front and back of the box. These can be tilted up, down, or side-to-side for directing the air where needed. The removable air filter prevents dust and dirt from building up on the fan blades.


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.


Advent Air Warranty Coverage

2-Year limited 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.

Customer service was great! There was a slight delay in shipping all the parts (due to an internal issue), but I was kept informed & everything arrived as ordered. I would recommend this company & this product.

Works like a charm!



by:

The A/C unit worked great, the install and hard start kit were easy.
Problem i have is the compressor locked up about a month ago while on a trip, $[XX] later have a coleman mock 3 now. An emergency buy to keep cool.



by:

Love the product, easy installation for a beginner like me.



by:

Overall an excellent purchase. Delivery was quick. Installation was relatively easy but I was just replacing an existing unit. The only issues might be no description on where to route the wire, which side the unit is wired on and it doesn’t cool as well as I had expected it would.



by:

Mounted it to my race trailer. It has run a lot this past year and has been great. The only issue I have had with it, is it tends to ice up on humid days when it has been running for 12 plus hours. Other than that it has been a life saver on those miserable, humid, hot days at the track.
I also have the optional heat which has also been nice to knock off the chill in the trailer on those cold mornings.



by:

works great. installed very easy. I only give 4 stars because it was delivered with a dent in the bottom frame. most likely done be ups. Better packaging to protect unit needed. most definitely would buy again from suppler . Outstanding price.



by:

Havent gotten a chance to really put it to use yet but its very light and easy to install



by:

The air conditioner that we ordered arrived in excellent shape and a week early. I have ordered 6 things from etrialer all have arrived ahead of time and in excellent condition.



by:

Has no thermostat to set temperature. You can only turn on and off. Runs and blows constantly. Not happy with that.

Thank you for your review. The air distribution box does include a thermostat that ranges from 65 F to 90 F 16 C to 30 C. The thermostat may not be working properly if your AC runs constantly, this unit does have a 2 year warranty.



by:

Unit was out of stock when I ordered but they beat the original delivery date by 4 days. It was in good shape and works great. Company always does it’s best and that’s not always the case.



by:

I really like these units, they seem to weigh less the the competition and are very affordable. I also like the three fan speeds instead of two from the competition.

Just got ac going to put in next week. Everything looks ok

Overall I'm happy with the unit. Installation was pretty straight forward double checking our progress along the way. Upon connection to power the GFCI tripped, this resulted into triage finding one wire penetrated by a screw from the junction cover. Start to finish with removal of the old roof vent and quite a bit of conversation was six hours.

One small discrepancy which was welcomed is the directions for the rooftop unit specify a 2.5" - 5" roof but further provide ducting instructions for 1"-2" roofs. I had purchased plywood anticipating the need for a spacer but happily skipped it.

Originally shipped unit was damaged in transit and etrailer made that whole exchange quick and easy, I was actually quite impressed.



by:

shipped super fast...easy install (mechanical knowledge highly recommended)...however, the ductwork from the rooftop unit to the ceiling unit only built for 2-4 inch thick roofs.(duct is perforated to shorten if needed but in my case, i have a forest river work-n-play with a 4.5 inch thick roof. therefore i had to play tin knocker and fabricat an extension to connect the ducts.
otherwise, installation was as i expected. heat strip and start capacitor installed with ease and very well illustrated instructions.
people complain of the heat strip not heating their unit. it wasn't designed to heat the unit, just take the chill out or supplement the furnace which then works nicely to heat the cabin quickly.
i have yet to put it to the test this summer (2023) at the racetrack for about 4 days each month between april and october...



by:

The Advent Air Conditioner 13,500 Btu has been working flawlessly! We use it about once a month through the weekend.Its exactly what I needed to replace an older Rooftop model. I would definitely buy another one, thanks Etrailer.



by:

We love our air conditioner. It looks and works great! Fairly easy to install (if you have some basic skills). Would definitely choose this again, if the need would arise.



by:

Great a/c unit. Happy with the price. Installed myself - super simple/really quick. The “easy start” capacitor option is a “must have”. Very low current drain at start-up compared to the old one that I removed. Cools fast. My entire motor home (36 ft) was quite comfy in about 15 minutes. It could be a little quieter but the tv volume has been up to the challenge so far.



by:

Love the a/c it cools great. I was houng to buy another one but the price went up so high I'm goung back to repairing old units.



by:

First when ordering Jamie was very helpful and was able to answer my questions. I received my order actually one day ahead of schedule. But once I opened the box the unit was damaged. But I had mine off and a hole in roof so I opted to keep it and install. The unit was very easy to install and went together well. It is not any louder than my old unit. It looks very nice. And seems to work just as advertised. I am very pleased. I did email e trailer about the damage and they got back to me very promptly. We reached an agreement and again I’m very pleased at this point.



by:

1st of all i what to mentioned that etrailer has great customer service. I received My new air conditioner kit by UPS. I installed it on a Tuesday And what camping on Saturday the temperature was 105° outside Add the air conditioner and keep my camper 70° all day inside. I will highly Recommend this product. My camper is 117' fiberglass Casita.
I had to use the old Gasket with the new gasket that the new air conditioner came with Because my camper roof was to thin.



by:

etrailer customer service again never fails I received my shipment yesterday and one of the boxes was open and one part was missing I took a picture of it called customer service sent it to him and within 24 hours the replacement has been sent. There was no question about the claim or need to file it with UPS. I've had several different transactions with etrailer their website is great easy to use and if I have any questions, I can get quick answers from a real person and the customer service has always been great tracking etcetera highly recommend etrailer.

  • Recommended Replacement For A 15,000BTU Atwood RV Air Conditioner System
    Since you have a heat pump you most likely have a 9-pin connector for your controller and would not be able to replace just the rooftop unit with another brand and we don't currently carry any single Atwood rooftop units to just replace that sole part. Dometic bought Atwood and has been slowly phasing out all Atwood products so your best option is to replace the entire system. Your most cost effective replacement would be the Advent Air RV Air Conditioner w/ Air Distribution Box and...

  • Recommended Plug And Play Replacement For A Dometic RV Rooftop Air Conditioner Unit
    The number that you gave me didn't come back to anything but there is a quick way to tell if the Advent Air Replacement RV Air Conditioner for Dometic Setup w/ Start Capacitor # ACDOM135B is going to be compatible. First, remove the shroud and check the BTU rating of your current unit. You'll want to match or go higher than your current rating. The # ACDOM135B has a 13,500 BTU rating. If you have a 15,000 BTU rating on your current unit you'll want the # ACDOM150B instead. Second, remove...

  • Will RV Air Conditioner Replace Coleman Mach El Air Conditioner
    In order to find out if there is a replacement air conditioner that will allow you to use your existing Coleman Mach El wiring and distribution box you need to know what model it is.

    The Advent Air RV Air Conditioner System - Manual - 15,000 Btu - Black # ACM150BC would be an excellent choice for this application! The 15,000 Btu rating is one of the highest out there for an RV and it comes with a start capacitor to help minimize the amount of draw the AC unit needs at startup. This unit also comes with the distribution box which doubles as the blower vent and the controller. Be sure to pick up some sealant like part # 34427034145-1 for the install on the roof, and...

This AC unit also has the start capacitor for storing energy to make startup easier under less power draw, which is really nice with certain RV power supply locations.

  • What is Needed to Install Air Conditioner in Enclosed Car Trailer
    We can get you the air conditioning you need to keep cool in your enclosed car trailer; what you will need is a ductless AC unit with a distribution box that will control the unit as well as blow the air in, as well as a generator for a power source (if you don't have one). I highly recommend going with a 15,000 Btu AC because of its additional cooling power which will cool your trailer down quicker, especially with a 24 foot trailer, though I will list the options for both the 13,500...

  • How to Install Advent Air AC Unit to Cargo Trailer With 1.5" Thick Roof
    Yes, there basically needs to be enough support and depth for the upper Advent Air RV Air Conditioner # ACM150BC unit to properly install with the lower unit. This can be achieved by simply adding in some wood as a spacer. We did something similar to this when we installed the MaxxFan Deluxe Roof Vent # MA00-06200K on a 2017 Ford Transit T150 - I'm linking that installation video for you to reference!
