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 15,000 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.


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.

  • How to Determine the AC BTU Rating Needed to Cool an Enclosed Trailer
    Based on the square footage of your 28 foot utility trailer the minimum BTU rating you'd need from an AC unit would be 4,760. So the Advent 15k BTU unit part # ACM150C would easily handle cooling your trailer. There'd be no need to add a second unit. To determine how much BTU is needed for a trailer you take the square footage and multiply it by 20 btu and that's the minimum needed.

  • How To connect An Advent Air AC System With 1 Furnace Wire To A 2-Wire Furnace
    Typically if there are two wires running from the furnace to the AC system then it means that the furnace has power already connected to it and it sends that through one of the wires up to the AC until the system calls for heat, at which point the relay will close and send power back to the furnace through the other wire. You'll want to connect the brown and white wire from the controller # ACRG15 to the other wire send power back to the furnace. To determine which wire is which you can...

  • Picking Out Replacement AC Unit for 2015 Jayco Jayflight 26BHS
    I don't know what unit you have on your 2015 Jayco JayFlight 26BHS but if it happens to be a Dometic the Advent Air Unit part # ACDOM150 that you referenced was designed to easily replace Dometics so it would be a really great solution. It uses wiring connectors that would plug right in and allow you to use your current thermostat. Otherwise the part # ACM150C is a really great option that comes with a start capacitor and an air distribution box.

  • Recommended Advent Air Replacement For A Coleman 45000 Series RV AC System
    Without the full number I don't know exactly what your BTU rating is so you could need the # ACCOL135 (13,500 BTU) or # ACCOL150 (15,000 BTU) if you're just wanting to replace the rooftop unit and keep the rest of your Coleman system in place. You can always go with a higher BTU rating than what your system is but you wouldn't want to go lower. If you're wanting to replace the entire system then for 13,500 BTU's you would need part # ACM135C or the # ADV94FR if you want a wall thermostat....

    For non-ducted AC applications you need to use a roof vent setup like the air distribution box part # ACRG15 that you referenced with the unit itself like part # ACCAR150. Or we have this setup as a kit with part # ACM150C which is the AC unit and the roof vent.

    Great question. We do have the Advent Air Rooftop RV Air Conditioner # ACM150 with the interior components. It is part # ACM150C and it also includes the start capacitor.

  • Are Advent Air RV Air Conditioners Able To Be Installed On Enclosed Trailers
    Advent Air has recently updated their warranty terms and will not support usage of their AC's unless they're installed on a camper or motorhome. You can still definitely use their systems, but you would be voiding the warranty and have to pay out of pocket for any issues or replacement parts. If you want to still go with them then you can get the Advent Air RV Air Conditioner System # ACM150C and heat strip # ACMHD. If not, then I recommend going with the Furrion Chill HE RV Air Conditioner...

  • AC Unit Recommendation for 32 Foot Enclosed Trailer
    AC unit BTU ratings typically call for 20 BTU per square foot. So for a trailer that is 32 foot long and most likely 8 feet wide you'd have 256 square feet to cool. That means you'd need a minimum of 5,120 BTU to cool it effectively. So the 15k BTU Advent # ACM150C that you mentioned would be way more than you'd need but it would cool the trailer very quickly. Another option is the 13.5k Advent part # ACM135CH which comes with a vent box, a heat strip (provides heat if needed), and a start...

    With no ceiling assembly on your 2017 Forest River Rockwood Signature Ultra Lite Travel Trailer RV, it sounds like you might have a ducted system. The Advent AC unit part # ACDOM150 that you referenced will work great as a replacement for a Dometic Duo Therm unit that you have and can actually be used as a ducted or non-ducted unit since this is just the vent assembly.

  • Can an Air Conditioner be Installed by a Do-it-yourselfer in an Enclosed Trailer Prepped for AC
    Since the trailer you are getting has the opening, brace, and wiring ready to go all the hard stuff will have already been done! I don't think you will have any problem installing AC unit # ACM150C yourself. It pretty much just bolts on. Two people are recommended for installation; one inside and one outside, to make sure it is lined up properly, but other than that there isn't anything special that needs to be done.

  • Recommended AC Unit for 22x8x7 Foot Race Trailer
    Since you don't currently have and AC unit, I recommend the Advent Air Rooftop RV Air Conditioner w/ Ceiling Vent and Start Capacitor - 15,000 Btu - White # ACM150C. This will give you the ability to cool your race trailer faster and won't have the big power draw at start due the integrated capacitor. The Advent Air Command Rooftop RV Air Conditioner - 13,500 Btu - Non-Ducted - White # ACM135CH will also work well for you.

Check your air filter and clean it if it is dirty and clean up/repair any damaged wiring or connections.
