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.

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. 572881

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. 647387

Review from a similar AC Unit in RV Air Conditioners


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. 664585

I bought this for a 1983 ford shasta r/v Took about 1 1/2 hours to install. would have been less time but I had to reroute the 12/2/ rx to the other side. Was very easy to install. So next time I hit a very low tree branch and rip off my a/c unit I will get another one here!!! 489289

Review from a similar AC Unit in RV Air Conditioners


I'm planning on using my trailer as a workshop so heat and AC were important. This AC unit was easy to install into the existing 14x14 vent. Took me about an hour to install and everything went smoothly. My trailer is 28 ft long so I'm thinking that I'll be needing a 2nd unit at the far end. I'll decide that after I'm finished insulating the walls. I've already put in 2 inches of rigid foam on the roof and that alone made a huge difference. 655942

Review from a similar AC Unit in RV Air Conditioners


The unit seems to be a top of the line quality product. Installation was fairly straight forward except the instructions are outdated. Instructions tell you to remove the receiver cover to prep it for mounting the Coleman control panel. The cover is not removable, it's now a high density foam. Also the supplied hardware is not long enough to go through the cover. The photos in the instructions are very hard to determine what they are of. 510096


Comments
Labor Day weekend 2018 we were camping at a site in direct sunlight. While running the unit on high we experienced a smell of something electrical over heating. I feel that the compressor failed. I have been in touch with the company and have the location of the nearest service location but have not been able to take the RV there yet. There is a 2 year warrantee so it shouldnt be a problem just an inconvenience.

Review from a similar AC Unit in RV Air Conditioners


As with other orders, the generator showed up on time and in good shape. The etrailer videos were very clear as to remove the old AC and replace it with the new Advent unit. The etrailer videos also showed to install the capacitor, the heat strip, and the distribution box. We were worried about getting the unit on the roof of the camper however it really was not a problem ….. we leaned a ladder up against the camper, tied a rope around the box, then leaned the box against the ladder. One person got on the roof and pulled the rope while two more people pushed from below... no problems and in about a minute the box was on the roof. The unit is now installed and looks good …. no power at the storage yard so I can only assume that the unit works as it is supposed to (like ever thing else we have ever ordered from etrailer). Good Job guys! 644424

Received Advent Air Replacement Rooftop RV Air Conditioner for Carrier Setup 15,000 Btu White- ACCAR150 in excellent condition by UPS. Replaced one of my old Carrier Air V air conditioners on my 32' Damon Daybreak motor home. It was easy to install and the conversion kit that came with it worked very well. Quiet even when running on high speed. Used the same remote and ceiling mount I had with my Carrier Air Conditioner. 528083

Review from a similar AC Unit in RV Air Conditioners


This unit can't be beat if you are replacing a stock Coleman--Avery straightforward installation. Airflow is better than my old Coleman but temperature is not. I've taken 3 trips with this Advent on Summer days with temperatures in the 90s, and in all cases the output temperature never got cooler than 60. The old Coleman could blow 50 degrees. 551026


Comments
Where are you measuring the 60°? According to the manufacturer, ASA Electronics, if your trailer has a ducted system, its possible that theres a leak in the ductwork. The best way to rule out the AC unit itself is to measure the output air temperature right as it leaves the unit.

Review from a similar AC Unit in RV Air Conditioners


SUPER pleased with the product. It was exactly as described and performs exactly as expected. The installation was simple, do-it-yourself, (less than 30 min) using 1 screwdriver and 1 nutdriver. The 15,000 btu unit cools my 41' park model in less than 20 min. Super quiet, and efficient. This unit was used to replace a Dometic Duo Therm and I did not have to modify anything...straight plug and play! Many thanks to the team at etrailer for the great service and lightning fast shipping! I will definitely be a loyal future customer. 540255

Review from a similar AC Unit in RV Air Conditioners


This is a direct replacement for a unit that I have. A tree branch put a hole in the condenser. This was not the fault of the unit. I was able to remove the six Phillips head screws on the inside shroud, unplug two cables and remove four 10mm bolts, then remove the old unit. once the old unit was out of the way place the new unit in place and reverse the process. I think the whole process took me 30 minutes to complete. It works just as well as any other unit I have owned. 518681

Amazing product, I will definitely recommend Advent to all my RV friends. Extremely easy to install, just a little to heavy to get up a ladder alone so i used a tractor to lift the unit to the roof of my RV, 4 bolts on the inside to remove and the wiring harness and off with the pos demetic, placed the Advent right in place bolted it down turned it on and instantly got cold air, very cold air! Only thing you have to install which I think the factory could do but, was easy. 516122

Ask the Experts about this Advent Air RV Air Conditioners

  • What Size Generator Is Needed to Use the Advent Air RV Air Conditioner
    The Advent Air RV Air Conditioner with Ceiling Vent and Start Capacitor part # ACM135BC requires 3,000 watts for starting and 1,000 watts while running therefore a 2,000 watt generator would not be suited for this or any RV air conditioner for that matter. Instead, I recommend the etrailer Portable Inverter Generators part # 333-0002 which has a 3,200 watt starting and 2,900 watt running power output. This will give you enough power to start and run the air conditioner as well as power...

  • Recommendation for Adding AC Unit to Small Enclosed Trailer
    The best option we have available for your converted enclosed camper is the Advent Air RV Air Conditioner # ACM135BC because it's going to provide the most efficient cooling solution for the camper's interior during those hot summer months. We do not have any smaller AC units available and anything smaller we offer will be something like a powered ceiling fan vent which will only work to circulate air around the camper and not actually cool it down. As you mentioned in your question...

  • Generator that Can Power Advent 13,500 btu AC Unit for RV
    Since using the included start capacitor is standard install procedure the etrailer Portable Inverter Generators part # 333-0002 which has a 3,200 watt starting and 2,900 watt running power output would work great with this generator setup.

  • 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.

  • Small Complete AC Unit for Transport Trucks
    We have a good solution for you the Advent Air RV Air Conditioner w/ Air Distribution Box and Start Capacitor part # ACM135BC would be a great choice. It will require 14"x14" hole to be made in the roof but after that it is straight forward and has everything you will need. The air distribution box has the controls on it to turn it up or down and the start capacitor will help to ensure it doesn't draw too much power when starting it.

  • 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...

    All of the Atwood AC units that are black are Ducted units like # AT15032-22 and are not non-ducted units like # AT15025-21 you referenced. The only way to use that unit and make it have the black cover is to purchase the cover separately as the Replacement Hardshell Shroud for Air Command Rooftop RV Air Conditioners - Black # AT15051.

  • Will 13,500 Btu Advent Air Conditioner Cool Enclosed Trailer
    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. For generators I recommend the etrailer 3,200 Watt / 2,900 running watts # 333-0003 if you do not have a lot of other appliances...

  • 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.
