Features to know about

Cooling That Helps the Cabin Recover

Advent Air AC Unit

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 15,500 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.

Replaces the Rooftop Unit Only

Advent Air 6-Pin Connector

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.

Designed for Updated R32 Systems

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.

Seals and Cushions the Roof Opening

Advent Air Foam Pads

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.

Easier Installation and Maintenance

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.

Optional Upgrade for Easier Startup

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.

Video Transcript for Review of Advent Air RV Air Conditioners - Black 15500 Btu RV AC R32 - ADV84QR

Hi, everybody. Andy here with etrailer. Let's take a quick look at this Advent Air Black 15,500 BTU RV Air Conditioner. So, this 15,500 BTU RV AC is designed to cool down your camper or motor home quickly and efficiently. And this is gonna be a solid upgrade if your current unit isn't keeping up. Or it could be a great option if you're adding an AC for the first time.

So, this is specifically made for RVs like your motor homes, travel trailers, and fifth wheels. However, this has not been designed nor intended for use on things like school buses, food trucks, utility trailers or off-road vehicles, because typically those type of roofs are not designed or built to support an air conditioner on top. So, a 13,500 BTU unit would be ideal for smaller RVs in moderate climates. It's gonna handle those normal conditions without overloading your system. But this is a 15,500 BTU unit, so this is 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. Before we go any further, let me give you a closeup here and give you some measurements just so you have a good idea of the size. So, looking at the overall length from end to end, we're sitting pretty close to 32 inches long. And then, the overall width at right about the widest point here, about 26 1/4 inches. And then the overall height anywhere from about 13 1/2 to 14 inches tall.

So, you're gonna be able to use this with ducted or ductless system. You're only getting the air conditioner here with thiS. So, you are going to need other components like an air distribution box and a thermostat. And those items are going to have to be compatible with the R-32 refrigerant. That's what this unit uses.

That new R-32 refrigerant complies with the new EPA regulations that took effect in 2025. And that refrigerant is gonna be more efficient and environmentally friendly compared to the older R-410A systems. So, because of that new refrigerant, this is not going to be backwards compatible with any components that do not use the R-32 refrigerant. So, basically anything pre 2025. So, if your thermostat in your air distribution box are older, you will need to replace those as well to work with this AC. The good news is we do carry complete systems here at etrailer, so you can pick up the type of air distribution box that's gonna work for you. Whether manual or thermostat control or ducted or ductless, what have you. You can find the system that's gonna work best for you and have everything that you need, and everything will work together, especially with that new R-32 refrigerant. Now, performance wise, you're gonna get consistent cooling throughout the space. This also includes thick gaskets with foam pads that are gonna sit between your AC and the roof of your RV. So, that's gonna help prevent leaks and air gaps. It's also gonna cut down on noise and vibration while you're going down the road and while the AC is running. And the outer cover is made of durable black plastic. We do also have this same unit available in white. But this cover is gonna do a great job of protecting the internal components from weather and debris. And if you ever need to remove this, it's held in place by Phillips head screws. So, you just remove those screws, remove this cover, do whatever cleaning or what have you, you need to do. Replace the cover and the screws and you're good to go. This does include a wiring harness that's going to come down from the front here out of the bottom and run through your roof. Speaking of roof openings, this is going to fit your standard 14 1/4 by 14 1/4 inch roof openings, and it's going to work with thicknesses between 2 1/2 and 5 inches thick. So, this will not include any hardware. Again, the bolts typically come with the air distribution box that's gonna work, so you're not gonna get any hardware with this. Installation should be pretty straightforward though once you get everything that you need. But 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. Well again, my name is Andy. Thank you for joining me.

Easy to install, you just need a male to male 6 pin converter to attach to old Dometic controllers.
Other than that, excellent.
And as a bonus, it's quieter than the old Dometic I had.
by:
This unit is not compatible with the GE unit that I asked if it would be compatible too. I now need to return this unit hopefully for a full refund

The part has been great. Easy to Install. I may have missed it in the write up but it wasn't a direct fit as it needed a 9 pin to 6 pin adapter harness for my RV. Fortunately, my mobile mechanic had one in his truck so we didn't have to make on. I believe etrailer sells it for around $50.
by:
This was a direct replacement for my 2013 Dometic AC unit right down to the 6 pin plug and the mounting bolts. It hooked up to the existing control unit without issue and runs all speeds.
by:
As of 5/24/26 @ 15:00 hrs central time the Advent ACM135B is installed and fully operational, cooling the bedroom of my rv perfectly.
Product arrived in excellent condition with no defects. Installation was as expected. Did rent a material lift from Home Depot which made the trip to the roof much easier and safe for this old man of 75yrs.
Thank you for the ease of ordering and your contact to let me know status of my order.

You're very welcome William, I'm delighted we could help!!!

by:
First one made it in quick but I was slightly disappointed when my electrician wired it in and the fan motor didn't work. That disappointment faded as soon as I called customer support. Not only were they polite and helpful, they shipped the replacement before receiving my return which meant I didn't have a gaping hole in my roof to keep covered long. New one works perfectly. Couldn't be happier with the customer service I received. Will definitely be a returning customer.
by:
Just got back from Las Vegas, NV air conditioner ran amazing. No issues, just nice and cold to freezing in my palomino backpack camper! Temperature outside was about 102-106 this weekend, September 11th 2026.
by:
You all did great...the price for everything was affordable and I liked the free shipping. This AC unit blows the cooler air a lot better than the original one.
by:
The units work as they should but the best part of everything was dealing with NikkiR in customer service she is amazing, very on point and relatable she was inquisitive about our situation and very helpful, absolutely stand behind Etrailer have made multiple purchases with them and the customer service with Nikki was by far the best I have ever had
by:
If you really have NO experience with rooftop units, maybe you should go with a complete kit (including the control box/thermostat). If you have "some idea" of what you are doing, you can figure it out. This unit comes with a six pin plug that feeds the fan and compressor. Nothing more. Not even a wiring schematic. Not a big deal if you know how to connect things up. But if you don't, yea, go for the whole kit. We installed this on a 2005 31' Jamboree motorhome. I had to clip the connector off and connect it the old fashioned way (head scratchin' and wire nuts). I also used the control box original to our RV (more connector cutting, etc.). Still, it took only a couple hours to install. It looks great, works great, and (the most important part) the wife is happy. Our old, original unit still worked but was pulling about 27 amps - way too high. I think the power problems we had at an RV park a year ago (very low voltage) killed the compressor (low voltage = lots more heat). This one is pulling about 13 amps. Oh, you really should get some help getting it to the roof. I don't have any friends so I did it myself (sucked!). But it can be done. Just be really careful, take your time, think it through, and stretch those muscles before you get under it. Hopefully, you have a friend or two who can help. Ok. I'm off to take a nap in the cool air.
by:
As I stated after my last purchase of a Advent AC. The six pin plug at the end of the umbilical cord does not engage with existing control boxes force a rewire of the cord using the old 6 pin connector. I'm thinking of using another brand and distributor in the future
by:
This is my fourth Advent unit I have purchased recently. The units themselves function well and customers are very happy but, on every unit, the six pin connector would not fully engage with the existing control box. Could not adjust the pins in the connector so is was forced to rewire unit using the old unit harness. I am considering going in another direction in the future.
by:
Works good install, and didn’t notice that it was bent where the compressor and the fan motor mounts to the base plate had to Try straightening it the best I could the fan would not turn at all once I straighten it out better it is working
by:
Well I already told you the unit was damaged in transit, I did repair it by myself, it was dented in next to the compressor area, subframe metal was dented, plus the units wiring harness was identical to the receiver end of the existing on the rv wiring box, in other words, the prongs weren't received into each other, since they were the same, so even tho I may have ruined my warranty by cutting the end off the unit and wire nutting the old one in its place,but it works, could just fine, the old unit was 19 years old, everything is still the same on the unit, it was light weight, and cools just fine
by:
Easy to install but need a new thermostat setup to be compatible with r32 freon

@David That's great to hear!
by:
Very fast shipping have not hook unit up looking forward to it.Very well built unit and good value Thank You
by:
It installed in the same place as the old Colman and installed fairly easy. However the “direct” replacement as advertised is not entirely true. The air delivery box will not work. The control and thermostat will not work so I ordered more parts from here and I’m still waiting on it to arrive to see if I wasted my $800 or not. So far not real good feeling about it.
by:
A/C worked well. Hopefully it will outlast the Coleman A/Cs (2) that only lasted 6 years each. I was able to install it and have it up and running the same day it was delivered. Thanks Much!
by:
Needed a male connector off of the air conditioner was a female connector of the air conditioner had to swap off old air conditioner
by:
Works great, direct replacement.
by:
Bought an Advent for a direct replacement for my living room a/c last year. Bedroom a/c went out this year. Have had great success with the replacement from last year. Easy plug and play installation.
by:
The unit was supposed to be plug and play compatible with the dometic controller. That is why the 4 star review. The plug had female pins instead of male pins. Other than that the unit performed as expected.
by:
The unit has never worked right. It doesn't ever shut off. I have always had my A/C set on auto so when it reaches too hot, it will come on and when it cools to a set temperature, it cuts the unit off. This unit will not do it. I have to go and turn the breaker on to turn the unit on and then go and turn the breaker off to shut the unit off otherwise it will run none stop.

  • Is there an Adapter for Advent AC to Coleman-Mach Distribution Box?
    Hey David, thanks for reaching out. Unfortunately, there isn't an adapter that will allow the Advent Air AC # ADV84QR to communicate with a Coleman-Mach distribution box. Since your Advent unit uses a different connector and control system, you'll need to replace the distribution box with one that's compatible with the Advent Air unit. Depending on your RV's setup, you'll need one of the following: Non-ducted system: Advent Air RV Air Conditioner Air Distribution Box with Built In Thermostat...

  • Replacement AC for Dometic B57915.711C0
    Hey Jonathan! The Dometic B57915.711C0 you have now is an old R410A unit. The Advent Air # ADV84QR is an R32 unit which means you will need a complete replacement with an air distribution box (ADB) and thermostat. Everything switched to R32 in 2025 due to EPA regulations. Unfortunately. none of these new AC systems are backwards compatible with the R410A parts. To replace your Dometic you need one of the following: -Advent Air RV Air Conditioner System - Single Zone - 15,500 Btu - White...
