Keep your RV comfortable after long drives, sunny afternoons, and warm-weather camping days. This 13,500 Btu unit connects to your existing Advent Air R32 system to deliver steady, consistent cooling throughout the cabin.
After a long drive or a full day parked in the sun, your RV can hold heat in the roof, walls, and furniture, well into the evening. This 13,500 Btu rooftop AC delivers 430 CFM of airflow to help bring cabin temperatures down and keep cooled air moving through your compatible Advent Air setup.
If the rooftop AC is the part that needs replacing, you may not need to change the entire interior setup. This unit replaces the outside air conditioner and connects to compatible Advent Air R32 air distribution boxes and controls. The 6-pin plug helps link the rooftop unit to your existing compatible system without rewiring the whole AC setup.
This replacement unit is made for compatible AC systems that use R32 refrigerant. That matters because older systems and newer R32 setups do not always use the same controls, wiring, or interior components. Before installing, confirm that your current air distribution box and controls are compatible with this R32 rooftop unit.
A rooftop AC replacement needs a good seal where the unit meets the roof. The thick, collapsible gasket helps block rain and hot outside air from entering around the opening, while six foam pads help cushion the unit and reduce vibration at the mounting point. That helps the AC sit securely while keeping the cabin drier and quieter.
Replacing a rooftop AC is easier when the unit is designed to connect to the system already in place. This AC uses a bolt-on installation and includes the wiring harness needed for compatible setups. The UV-resistant hard plastic cover protects the internal components and can be removed for maintenance and cleaning when the unit needs attention. If you'd like help installing your air conditioner, check out our Installer Locator to find an installer near you.
Some camping setups ask more from your AC than others, especially when you are running on generator or campsite power. The optional start capacitor (ACMSCKIT) can be added to help the compressor start more reliably. This upgrade is not included, but it gives you a way to build out the system for the way you camp.

Hi, everybody, Andy here with etrailer. Let's take a look together at this Advent Air Black 13,500 BTU RV Air Conditioner. Now this 13,500 BTU RV air conditioner is designed to cool down your camper or motor home quickly and efficiently. So this is gonna be a solid upgrade if your current unit isn't keeping up or it'd be a great option if you're looking to add an air conditioner for the first time. So this is made specifically for RVs like your motor homes, your travel trailers, and fifth wheels. I do wanna point out though that this is not intended for things like school buses, food trucks, utility trailers, or off-road vehicles, because typically, those types of roofs are not designed to support an air conditioner on top of the roof.
So again, this is going to be a 13,500 BTU unit. This is gonna be ideal for those smaller RVs in moderate climates. It's gonna handle normal conditions without overloading your system. A 15,500 BTU unit, which would be the next step up from Advent Air in this series, that's gonna be better for your larger RVs in hotter climates or heavy sun exposure. It's gonna cool down faster and it's gonna keep up in that extreme heat.
Now, before we go any further down the road here, let me go ahead and give you some measurements just so you can be confident this is going to work for you. Measuring the length from end to end, we're pretty close to 32 inches long. And then measuring the width at pretty much the widest point here, we're gonna be sitting close to 26 and 1/4 inches, and then the height's gonna be about 13 and a half to 14 inches tall. This is just for the AC unit. You're gonna be able to use this with either a ducted or ductless system.
You will need other components like an air distribution box and a thermostat. So you'll need to pick up an air distribution box that's going to be compatible with what you've got going on inside of your camper or RV. You want something that's gonna work with your ducted or ductless system, and you'll have to choose whether you want a manual box or a box that'll work with a wall thermostat. So, and all of those components do have to be compatible with the new R32 refrigerant. That's what this uses.
This complies with the new EPA regulations that took effect back in 2025. That refrigerant's gonna be more efficient and environmentally friendly compared to the older R410A systems. And because of that new refrigerant, as I said, this will not be backwards compatible with any components from the pre-2025 that use the old refrigerant. So it won't be able to work with those components. So if you don't already have components that are designed for the R32 refrigerant, you will need a new, a complete system. AC, air distribution box, thermostat. And the good news is we do carry this as a complete kit as well. So if you need all those other items, do take a look here at etrailer and we have this available in a complete system, if that's what you're needing. Performance-wise, you're gonna get consistent cooling with this throughout your space. It also includes a thick gasket with foam pads that are gonna sit between your AC and your RV roof, and those do a a few important things for you and help seal everything up to prevent water leaks and air gaps. It's also gonna cut down on noise and vibration while it's running. This outer cover is made from durable black plastic. It's going to do a great job of protecting the internal components from weather and debris, and you can easily remove this as well. It's held in place by Phillips head screw. So if you ever need to take the cover off to clean it out or what have you, it's gonna be very easy to remove the screws, remove the shroud, do whatever you need to do. Then you can replace the shroud, replace screws, and you will be in business. This does include a wiring harness that's going to come down from underneath the front of the AC and you'll run that through the opening in your roof and plug that into like your air distribution box. Installation's gonna be straightforward. This is gonna bolt into your roof, but again, this is not going to include any hardware. Typically the bolts, the hardware, is going to come with the air distribution box that's going to work with your particular camper or RV. This is designed to fit standard roof openings that are 14 and 1/4 by 14 and 1/4 inches. And this is going to work with roof thicknesses from two and a half to five inches thick. So again, we do have complete systems available if you need more than just the AC. You're gonna be able to find that here at etrailer. If you need help with installation on this product page, typically underneath the photo section, we have a link that will take you to our installer locator. Click that link and answer the questions that it has for you and that locator will find an installer in your area that etrailer has partnered with to install this for you. By the way, we also carry this in white as well, if you're looking for something other than black. That's gonna wrap up our look today. Again, my name is Andy. Thank you for joining me.

Glad to hear it's working well for you! To what knobs are you referring to though? This is just the rooftop unit and there shouldn't be any knobs. Are they on the air distribution box?
