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.


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), you'll 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.

Video Transcript for Review of Advent Air RV Air Conditioners - 13500 BTU White RV AC System - ADV23SR

Hi, everybody. Andy here with etrailer.com. Let's take a quick look at this Advent Air 13,500 BTU White RV Air Conditioner System. Now this is going to be a great option to consider if you're looking to replace, upgrade, or add an air conditioner on your RV's ductless system. And this 13,500 BTU per hour air conditioner is going to quickly and efficiently cool down the inside of your RV or camper. And this does use the more energy efficient R32 refrigerant, which meets the 2025 EPA regulation.

So because of that, this unit is not going to be backwards compatible with any air conditioner system from 2024 and earlier. Now this is designed for use for motor homes, travel trailers, and fifth wheels, but I do wanna let you know that this has not been approved for use on school buses, food trucks, or enclosed utility trailers or off-roading vehicles, because typically those types of roofs are not built with the support needed to handle the weight of an air conditioner system. And there might be too much flex on that roof that could potentially damage the roof or the air conditioner system itself. Now this is going to be a bolt-on installation with the hardware that is included with this system. And this is going to fit roofs from two and a half inches to five inches thick, with an opening size of 14 and a quarter inches long by 14 and a quarter inches wide.

Looking at some measurements of just the unit itself, the overall length from front to back, we're sitting at about 31 and three 16ths inches long. And then the overall width at the widest point here, we're sitting right about 24 and seven eights inches wide. The overall height, about 12 and 13 16ths inches tall. The unit itself weighs a little under 70 pounds. Now this also includes this air distribution box, which has a built-in thermostat.

And we do have a dial on the left and on the right. The dial on the left is going to control the three cool settings, and the cool settings are here. And then the three fan speeds obviously help you increase or decrease the airflow. Now if you add an electric heat strip to this system, and that heat strip is sold separately from this and that's gonna be great to help remove the chill on cold mornings. So if you add a heat strip to this system, this is also going to control the heat setting with this dial here on the left hand side.

The dial on the right is going to let you set the temperature. And then there are going to be registers here and here, which are going to be adjustable to allow you to direct that airflow where you want it. They can be tilted or rotated to the direction that you need it. And then our removable air filter here is gonna help prevent dust and dirt from building up on the fan blades. So you can see that one register here on this end. Let me see if I can just tip this over here a little bit so you can see, get an idea of what this is gonna look like mounted into your ceiling. So you got that vent, that register there. And then here on the other side. Hopefully it gives you a good view. And I'll just give you a view of the inside of the unit as well. So let me go ahead and just prop this back up here real quick. I also wanted to show you that this does include a start capacitor, which is a great addition to this system. And so let me bring this up just a little bit closer. As you might know, this start capacitor is going to actually jumpstart your air conditioning unit if your campsite or generator isn't supplying just enough power. So this capacitor actually stores energy that will later be used to jumpstart your AC. This is gonna be a pretty easy install inside of your air conditioner unit. So that is included, you will have to pop that into the air conditioning unit itself. And then I went ahead and removed the the 12 Phillips head screws that secure our cover here. I wanna go ahead and remove the cover real quick, just to give you a brief view of the inside. So as you can see, that cover is going to pop right off. And so you're gonna be able to easily do any maintenance that you might want to do, do any cleaning or anything like that. This does have a six blade fan with a motor that's gonna give you sufficient airflow. And the airflow is 500 cubic feet per minute. So when you are ready to just pop this back on, it's not gonna be an issue at all. After you do whatever cleaning you need to do or maintenance you need to do, you can just simply pop this cover back on. By the way, this white cover is hard plastic, so I think it's gonna do a pretty good job of protecting the internal components from debris and water and things like that. So you'll just pop that cover right back on, just like that. And then just secure it with the the 12 Phillips head screws and then you will be on your way. Now underneath this, you won't be able to see, but there is a collapsible gasket and foam pads that are going to provide support between the roof and the AC. So that gasket is actually going to seal the opening to prevent water seepage and air leaks, so you don't have to use fresh sealant because of that collapsible gasket. And then those foam pads underneath are going to help reduce noise and vibration. Those pads are actually gonna be in between the roof of your camper or RV in the base of this air conditioning unit. By the way, it's a metal pan underneath, so that gives you quite a bit of stability and durability. And it does include a wiring harness. It's gonna be one plug. And typically we do provide pictures of that wiring harness on this product page. Well, I think that's gonna wrap up our look today at this system. I do hope that our time together has been helpful for you. Again, my name is Andy. Thank you for joining me.
