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 second unit to boost cooling in an RV
  • Have a trailer or RV that is sectioned off or is ducted and need lots of air movement (CFMs) to keep it cool
  • Prefer a black rooftop AC unit to match your dark RV exterior

No, if you:

  • Have a hard time reaching to the ceiling to adjust settings on the thermostat and would rather have wall-mounted controls
  • Often go to extremely hot or very humid places that will need more power (Btus) to stay comfortable, especially if you travel with kids or pets
  • Camp in cooler seasons or places and need a little heat to take off the chill
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.

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.

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.

We are very pleased with the purchase of the 13,500 BTU Advent Air RV Air Conditioner for our camper trailer. Excellent customer service from the moment we placed the order.
Especially helpful was the video tutorial step by step how to install the AC.
It works perfectly and will almost freeze us out of the trailer on High!!!




by:

My husband installed this as a second air conditioner in our 5th wheel. Installation took a little longer than expected due to getting the inside template to line up with the main unit. Also, it is pretty noisy on medium and high; however, that doesn’t bother us as we like to sleep with “white noise”. Overall, it cools well and is a fairly straightforward installation with minor adjustments needed. If you are mechanically inclined, installation should not be an issue.




by:

Ordered this rooftop AC to replace an old one on my houseboat. Received in two days and installed in a few hours! Works great! May even add the optional heat strip for next winter.




by:

It's great product, but noisy. but it's a nice A/C.

I have bought several things from these guys and the service is great.I will continue doing business with them.

made too cheap Poor quality




by:

Very pleased with this unit. This was a new install onto a 2002 Palamino Bronco 1200 slide in pop up truck camper. Installed directly onto existing 14" roof vent. Total project took under 2 hrs. Camper was not pre-wired for A/C, so 20A circuit was installed using plastic wire conduit/moulding.

I had originally wanted to use a 2000w Honda generator to power camper, but will need to upgrade to a bigger generator to power this unit.




by:

My review is on Lori at etrailer, when I ordered my advent a/c unit I knew it would not be available for 6 to 8 weeks,she kept me informed & when they received a shipment let me know, delivery was quick. Thank you Lori for keeping me informed . Due to travel I won't be installing the unit till spring so I can't review it at this time. I have bought from etrailer in the past & will again in the future, Great job.




by:

Works great,a little loud




by:

Advent air conditioner arrived in a timely manner. Everything was as expected.
Installed the unit, and it worked fine. Only issue was that the instructions for installing the additional start capacitor were a little vague. Talked to David at etrailer, and he provided an excellent video that clarified the installation. It would be nice for etrailer to provided a roof adapter for my ProMaster to fit the contour of the roof, but I was able to obtain one from Impact Graphics to ensure a leak proof installation.
Have been very pleased with everything I have ordered from etrailer.

Great and EZ experience. Great price qwik del.

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


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.

  • Air Conditioner Recommendation for V-Nose Enclosed Trailer
    A smaller RV air conditioner unit with a lower vent assembly would be your best option like the Advent Air RV Air Conditioner w/ Air Distribution Box and Start Capacitor # ACM135BC. This puts out up to 13.5k BTU which would provide more than enough cooling power and also has a start capacitor which means less strain on your power supply. As long as your roof is between 2-1/2 inch and 5 inches thick this will fit and work great.

  • What Type of Outlet Does Advent Air RV Air Conditioner # ACM135BC Draw Power From
    The Advent Air RV Air Conditioner # ACM135BC that you referenced is designed to be powered from a 115 VAC style outlet like a standard house outlet. It would not need a 20 amp or 30 amp outlet.

  • Recommended Roof Top Air Conditioning Unit for Ram Van
    I recommend using the Advent Air RV Air Conditioner w/ Air Distribution Box and Start Capacitor - 13,500 Btu - Black # ACM135BC since it comes with a start capacitor that will help start the unit on limited power, which is something you will likely experience with a van conversion when not connected to a generator or shore power. This is a ductless unit that comes with an air distribution box included, so you can control the unit straight from that. You will likely need to build a frame...

  • 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.

  • What is Needed to Install 13,500 Btu Advent Air Conditioner
    So there's a few things that are going to be needed in order to install the Advent air conditioners, and for a tent trailer I do recommend going with the smaller 13,500 Btu. But the first thing you need to do is ensure you have a roof that is 2-1/2" to 5" thick in order to support the unit; you will also need to open a 14-1/4" long x 14-1/4" wide hole for the unit. Adding this AC will require not only the main AC unit, but also an air distribution box. For that you can use one of the...

  • Lowest Profile RV Air Conditioner
    The lowest-profile RV air conditioner available is from Advent, as their AC units stand 12-13/16" tall. They will fit roofs that measure 2-1/2" to 5" thick and require a 14-1/4" long x 14-1/4" wide opening. You can choose from either white or black in color: - White: Advent Air RV Air Conditioner with Air Distribution Box and Start Capacitor - 13,500 Btu # ACM135C - Black: Advent Air RV Air Conditioner with Air Distribution Box and Start Capacitor - 13,500 Btu # ACM135BC

    The RV air conditioners we offer do run off 120v power, and for a motorhome like yours the best option for a rooftop AC is a 13,500 Btu rating with an air distribution box as this will give you plenty of cooling power and easy controls. For that I recommend going with Advent, and you can choose from either White or Black in color: - White: Advent Air RV Air Conditioner # ACM135C - Black: Advent Air RV Air Conditioner # ACM135BC These are 115v rated but work with a 120v outlet, and also...

  • Recommended Replacement RV Air Conditioner for Dometic Setup
    I recommend the Advent Air Replacement RV Air Conditioner for Dometic Setup w/ Start Capacitor, # ACDOM135. This is a 13.5K AC unit that replaces Dometic units by plugging directly into your Dometic setup to work with your existing air distribution box. It plugs directly into your Dometic setup and works seamlessly with your existing, in-good-working-order Dometic air distribution box and thermostat eliminating the need of an adapter wiring kit.

    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).

  • Recommended Rooftop Air Conditioner for Cargo Trailer with 2,000 Watt Generator
    The best rooftop air conditioner unit we have for you is going to be the Advent Air RV Air Conditioner part # ACM135C for white or part # ACM135BC for black which puts out 13,500 Btu's. The reason that this is the best rooftop air conditioner is because it comes with a start capacitor. This is going to be needed as it reduces the amount of watts that is required upon startup. If you were not using the start capacitor then you would need a generator that has at least 5,000 watts which means...

    Yes, the 13,500 Btu Advent Air RV Air Conditioner with Air Distribution Box and Start Capacitor # ACM135C (White) or # ACM135BC (Black) will cool your enclosed trailer. These are ductless systems as I assume your trailer does not have ducts. That said, it will essentially need to always be on so you do need to monitor your generators and be sure they are full.

I also highly recommend a start capacitor to go with the AC in order to ensure your unit always has enough power to start up whenever you need.

Instead, I recommend the A-iPower 3,800-Watt Portable Inverter Generators - 3,000 Running Watts - Gas - Manual Start # 289-SUA2000i-2 which has a 3,800 watt starting and 3,000 watt running power output.
