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

Yes, if you:

  • Are adding an AC where one didn't exist before in a small trailer or as a 2nd unit to boost cooling in an RV
  • Need the most air output to reach every corner of your trailer

No, if you:

  • Have a hard time reaching to the ceiling to adjust settings on the thermostat and would rather have wall-mounted controls
  • Go to the extreme heat of the desert or the swampy South and need more Btus to stay cool
  • Camp where you might have chilly mornings and need a heating element to stay cozy
Ductless AC unit lets you replace an existing AC or add a new AC to your RV. Air distribution box has a built-in thermostat to control the fan and temperature. Start capacitor jumpstarts the AC when camp power or generator power isn't enough. Lowest Prices for the best rv air conditioners from Advent Air. Advent Air RV Air Conditioner w/ Air Distribution Box and Start Capacitor - 13,500 Btu - White part number ACM135C can be ordered online at etrailer.com or call 1-800-940-8924 for expert service.

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

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.

Easy install, fast shipping. Unit works great in my 16x8x7 trailer.



by:

Over the years I've bough two Advent A/C units from etrailer.com. Both units are doing great. I have encouraged others to consider Advent Air when they are looking for a replacement.

Did not receive this ac. Only received the capacitor and inside cover and control.

Unit was very easy to install



by:

there was damage to the shrouds of the a/c during shipping. etrailer was great at getting a replacement asap. Good people there. Yes I'd order and recommend them to others.



by:

This air unit works so excellent! It actually worked better than what we expected. Cooled our trailer that it got so cold we had to turn off. Best investment ever



by:

The thermostat wire was cut when we got it and when we took it to be installed they said it wasn’t covered inter warranty….

I will have our Customer Service team reach out to you. The AC unit does have a 2 year warranty.
-- Etrailer Expert Jenny N - 05/12/2022

This was purchase for a front 5th wheel living room. Discharge vents face the front and back of the trailer, it would be better if they were on the sides facing the couches. Unit is very loud even on low to be used while watching television. The included 7” mounting bolts are too short for a 5” thick roof plus the roof gasket. Needed to go up on roof and use my 220 lb frame to sit on top of the unit and compress some of the roof gasket with my wife inside to get 3 of the 4 mounting bolts started. Will need to go to a home improvement store tomorrow to buy a longer mounting bolt to complete the installation. The plastic prongs on the hole plug crumbled during installation and fell out. Not impressed so far, will need to wait for a warm day to see how it performs.

I changed the air box with thermostat like it alot better
James C - 04/18/2021

by:

I’ve had the advent ac unit for a year now and love it . Our fifth wheel was preprep for the second ac unit so it was simple to install. We use it mostly to cool the rig down after set up and on those hot humid nights or when the outside temps shot up in the afternoons . But yes I would recommend this unit . In fact if the need would ever arise I’m would order the direct replacement for the factory installed Dometic unit on the rear . Shipping was fast with no damage.



by:

First of all I just got it and I like what I see I appreciate your service and fast delivery now I got to go to work thanks Ron from Alaska



by:

It blows great and I’m proud to have it



by:

Works great. Installed just like the video. My order was damaged in shipping but Ed W. Went above and beyond to get it right. etrailer needs to give Ed W a bonus for his effort.



by:

This came in two boxes, both items arrived in great shape



by:

Received unit quick and in good condition. I won’t install till spring at that time I will update what I think of the unit. Thanks



by:

This Very easy to install great product highly recommend it

Works good big difference in cooling the trailer
Robert - 03/13/2022

by:

It works. It is a bit louder than the original AC.
When installing there were screws that protruded through the bottom of the AC that could possibly poke a small hole into the roof during installation.
etrailer is a very fair company, the AC had face damage when delivered and they made it right.



by:

Product arrived super fast and seems to work well (too cold currently to know for sure) etrailer had the best price I found and has excellent customer service. Will be doing business with them again

Ask the Experts about this Advent Air RV Air Conditioners



  • AC Unit Recommendation for Enclosed Cargo Trailer that is Insulated
    The Advent Air Rooftop RV Air Conditioner # ACM135 that you referenced would work great for your application but since you'll also need the ceiling vent and thermostat your best option is the # ACM135C which is a kit that includes that as well. This will give you great cooling for the smaller room and since you've done a great job insulating the room it will stay cool longer and easier. I am sure some people have successfully ran a generator while travelling but we do not recommend it....

  • Does Advent Air Rooftop RV Air Conditioner Need a Mounting Bracket
    The Advent Air Rooftop RV Air Conditioner # ACM135C does not require a mounting bracket to install, just a 14-1/4" x 14-1/4" opening and a framed with 3/4" lumber, as you can see by the accompanying cut out I added from the linked installation instructions.

  • Is Sealant Required to Install the Advent Air Rooftop RV Air Conditioner
    No, it is not necessary to use sealant when installing the Advent Air Rooftop RV Air Conditioner # ACM135C on your trailer. This unit is designed so that is not necessary because it has a thick gasket that prevents water from leaking in. I have added a link to the written install instructions of this AC unit for you to take a look at.

  • AC Unit Recommendation for 28 Foot Enclosed Trailer
    Based on the square footage of your trailer and the hot climate you'd easily get by with a 13,500 btu unit like the Advent Air # ACM135C. The units blow much colder air, plus this kit comes with the ceiling unit so that you can control it since your trailer wouldn't have ceiling ducts.

  • Parts Needed to Install a New Air Conditioner on a Trailer with No Current Air Conditioner
    To install an A/C on your cargo trailer that does not currently have anything for an A/C you will need a complete A/C set-up like the Advent Air RV Air Conditioner w/ Air Distribution Box and Start Capacitor # ACM135C. This will include everything you need for the A/C other than the power source. For the power you will need to get 12 gauge 2 wire and a 20 amp circuit breaker from your local home supply store to get power to the A/C.

  • Air Conditioning Kit Needed for a 6 x 6 x 12 Enclosed Cargo Trailer
    For an air conditioning kit I recommend either part # ACM135C in white or part # ACM135BC which is the same part but in black. These kits include a 13,500 Btu AC unit along with the ceiling vent and the start capacitor. When it comes to wiring for your AC unit this really need to be done by a professional. Typically our customers are just replacing old units so there is no wiring kit used to get everything hooked up to the electricity on your trailer.

  • Recommended Air Conditioner for 26x7-1/2 Foot Enclosed Racing Trailer
    For your 26x7-1/2 inch enclosed trailer, based on your photo you will want two units. If you simply want to replace the unit, I recommend the Advent Air RV Air Conditioner w/ Ceiling Vent and Start Capacitor - White # ACM135C. This will give you the roof top unit, the vent assembly with built in thermostat, and a start capacitor to make sure you can start the unit even when the shore power is at an amperage that isn't strong enough for most systems to start.

    The correct size air conditioner for your trailer is going to depend of several factors such as square footage, ambient temperature, number of rooms, etc. However, I can say that a 30' long enclosed trailer would be best suited with two 13,500 btu units. For this, I recommend the Advent Air Rooftop RV Air Conditioner part # ACM135C which is for non-ducted trailers that I assume is what you have. If you want the heat pump then use # ACM135CH instead.

  • Lower Power Draw RV AC Unit Recommendation
    The Advent AC Unit part # ACM135C is one of the lower drawing RV AC units as it only draws 1,450 watts and since it has a start capacitor it doesn't draw considerable more when powering on initially. I am not sure the wattage of the other accessories you mentioned but with this AC unit you'd have 2,000 watts left over to power everything else. Most likely you'd be fine though.
