This Advent Air AC unit lets you replace an old or broken air conditioner on your RV or camper. It works with your existing Advent Air or Dometic air distribution box, and it is compatible with Coleman Mach or Carrier setups if used with an adapter wiring kit (ACCOLKIT, ACCARKIT - sold separately). 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. And everything you need in order to replace or add an AC unit is included, which makes installation simple and easy.
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.
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 needed. Once installed, the hard plastic cover on the AC can easily be removed for maintenance and cleaning.
And in order to fully complete installation, this AC needs to be paired with your existing Advent Air, Dometic, Coleman Mach, or Carrier air distribution box and thermostat. Please note that an adapter wiring kit (sold separately) is needed if you are replacing a Coleman Mach or Carrier air conditioner.
Additional accessories can be purchased separately to improve the performance of your Advent Air AC unit. The start capacitor (ACMSCKIT) improves the performance of your AC by using stored energy to jumpstart it. And the electric heat strip (ACMHD) removes the chill on cold or frosty mornings in your RV, ensuring you stay comfortable. Please note that the heat strip will only work on Advent Air AC units.
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.

Hi. John with etrailer. Whether you're replacing a rooftop air conditioning unit on your trailer or if you're adding a new one, this is gonna be a good option for you. This is the new low-profile series from Advent Air. This is gonna come with a white shell or a black shell. This is gonna come in two different power requirements, depending on your camper size and the output that it can handle.
This is either gonna be a 13,500 BTU or today's installation, a 15,000 BTU. Now, in this particular camper, we replaced a much larger air conditioning unit with this smaller one that's gonna be a smaller footprint. This is good for anybody that's looking to make a little bit more room up on top of the camper, whether it be for solar panels or optional other equipment that you wanna put on there. We did a size comparison between this newer low-profile unit and the unit we took off. Let's go check that out right now.
Now, just real quick, we wanted to show you the size comparison between the unit that we replaced in this Everchill unit over here, and then the new Advent low-profile series here. And it's not always about the size. This unit over here is a 13,500 BTU unit while this advent here is a 15,000 BTU unit. It's just the dimensions are gonna be a little bit smaller for you. And this is something to consider if you have limited space up on top of your trailer or camper.
If it's loaded up with either skylights or vents, or TV antennas, and if your space is limited, you definitely want to check that. For instance, the height on our low-profile unit, we're gonna be running about 11 inches above your rooftop. Whereas on this unit here, we we inchesre about 14 inches. So you're saving around three inches just in height alone. As far as width, the Advent unit's gonna come in just around 25 inches or so.
And on the Everchill unit that we're replacing, it's about 30 inches. The other measurement I like to get is gonna be (tape measure snaps) from the intake and exhaust right here on the bottom. It stops right here. And this is usually where people run into problems on top of their camper because they'll have a TV antenna or something that's set up behind it, and it's gonna interfere with it. On our Advent today, that's only 11 inches. Whereas on the Everchill unit, we're running about 13 1/2 inches with that. So this is really an option to consider if you have limited space up on top. So that really was a dramatic difference in size between the two. If your camper can handle the power consumption, I would recommend going with as large a unit as you can take. This particular model, if you go with the 15,000 BTU, it's gonna draw 15.4 amps while it's running. So just keep that in mind and check your camper's power requirements. Make sure that you can handle that much. Let's go take a look at the inside and check out some of the controls. With this setup, you're going to get a thermostat here that's gonna power the unit. It's gonna be cool mode, a heat mode, and then a fan only mode. And it's gonna have three speeds on the fan, high, medium, and low. So to cycle through, you can just hit the mode button, and it's gonna control not only the rooftop air conditioner, but it'll control your furnace if you have one as well. If you just want fan mode, you can kick it to fan only, and then adjust the speeds to medium or low. As far as the air box down here, you're gonna have separate air duct controls. You can open these or close them. On this particular camper, we have a duct system, so we have the option of having some air exit through here or go through the duct system. So this will work for ducted or ductless systems. It has a washable, replaceable air filter element right here. You can just pull that out, wash it, replace it back up. All in all, I think this is a great little setup here if you're replacing or even if you're just gonna add air conditioning to your camper. Advent Air, they seem to be fairly easy to install. Whether you have a Furrion system or a Coleman system or a Carrier setup, we have different adapters available to make this unit plug and play. Especially if you're replacing the unit, you already have thermostat wiring run, this really is a fairly straightforward installation. If you wanna see how we installed our unit and the thermostat on this particular camper, stick around. So to begin our installation, we're gonna start on the inside of the camper. If you're doing this as well, and more than likely you're gonna be replacing an existing unit, it's gonna be similar to this. But depending on the manufacturer types, it's gonna be just a little bit different when doing this. But the first thing we're gonna do is get this cover removed. On this one, it looks like I have four Phillips head screws. We'll get these outta here. (tool whirring) (tool whirring) (tool whirring) So with that cover removed, it looks like we have four 10-millimeter bolts that are gonna actually be holding our air distribution box up here. (tool whirring) (tool whirring) (tool whirring) (bolt rasping) Now, more than likely, your electrical connections are gonna remain hooked up. Of course, you wanna make sure that you have any AC voltage turned off. You're gonna have both 120 volts up here and 12 volt wiring up here. Need to get the lower plate disconnected from the upper unit here. We can start, this is gonna be the free sensor. Now, our new unit is gonna come with a new free sensor. So we can disconnect this. That'll go up with the old unit. (connection popping) We can disconnect the box. Now, the good news is, and this is what you wanna look at when you're replacing, you wanna see that your plugs are gonna fit up with the new box. And in our case, it's going to. We have different adapters for different boxes and manufacturers, so you definitely wanna check that before you make a purchase. Other than that, the rest of this is going to be thermostat wiring, we're gonna disconnect. And then, our 12 volt wiring is gonna be right here. And then, our 120 volt wiring is gonna be right here. We have to open this box up and disconnect it from the inside. Okay, now with everything disconnected, there's nothing right now that's holding the top unit on. When we took the four bolts out, that was actually what's holding this unit on. So we're gonna head up to the roof on this camper and remove this unit and replace it with the Advent. (hardware clunking) I'm just gonna lift at the corners. There's gonna be a foam rubber seal that goes around, but it might be sticking to your roof a little bit. But, okay, tilt this up. You're still gonna have your wires like the free sensor wire, and then your control wires are still gonna be on. And you wanna be careful sliding the old unit and new unit around up here on your roof. Now, anytime you're up on your roof and you're replacing an AC unit, it's a good idea to inspect your roof and clean it up a little bit too. And that's what we're gonna be doing here today. Make sure we don't have any dry spots or dirt and we're gonna clean up the mating surfaces here, make sure we get a good watertight seal. (spray bottle hissing) (distant engine rumbling) (rag rasping) So when you're placing this unit, you just wanna make sure you get it somewhat close to lined up on the hole here. You're gonna be able to reach up from the bottom and adjust this however you need it. So that's gonna work for us. Now, we can head back inside and tighten it down. If you need to move this around one way or the other, you can just square it up. Make sure your seal is even all the way around. And before we continue on with the installation, we can reach up on the inside, and we're gonna pull down the power distribution cable that's up here. And now, it's also a good time to install the free sensor. Now, that's gonna come with your kit right here. We're gonna undo this, and the copper-colored end actually goes up into the evaporator up here. You're gonna see a blue plastic piece that this slides right into. And that is one of the things I like that Advent does. It kinda makes it easy. Some of the other manufacturers out there, you have to get a screwdriver and sometimes move the fins side to side just to get the free sensor up there. So we have this installed. And next thing we can do is install a control box. Now, you'll wanna have your bolt kit handy. Just gonna run this straight up. Now, all of your wiring needs to go on the one side here where the wiring goes. (wires rustling) You don't want anything caught on the other side. This is the intake side. This is where the air is gonna get drawn up into the air conditioning system. And the exhaust side over here, the cold air, comes down over here. So we're gonna be having a wall, the divider here, to keep these two areas separate. So we want to make sure everything is on this side, and it is right now. And we can just take our bolt and we're gonna run them up (bolt rasping) into the unit. And if you're lined up correctly, it should just, they should just start. (bolts clinking) I like to run the bolts up and make sure everything is centered, and then just snug 'em up. (bolt rasping) (tool whirring) And we're just snugging these up right now. (tool whirring) And once I make contact at all four corners, we'll make sure that this gets tightened up equally at all four corners here. (tool whirring) Now, as far as tightening down the upper unit to the lower plate down here, there are torque specifications in your instruction manual that tell you a torque value on these bolts. But I would also say that, you know, you obviously want this gasket up here to compress as much as possible but without deforming your ceiling. So just kinda use your own judgment when tightening this up. We don't want the upper unit to move. We definitely don't want it to leak, but each ceiling's gonna be a little bit different. So to begin the wiring, we'll start with, obviously, the easiest ones. That's gonna be the plug from the upper unit. It's just gonna get plugged right in. These will have a flat edge on the top and bottom and in the middle over here. And that'll let you know the orientation. This is only gonna be able to get plugged in one way. And then, our free sensor that we stuck in to the top is gonna have a pigtail down here. And that's gonna hook up just like the other one. (connection clicks) And then, from here, this is where it could be a little bit different for you. We're gonna hook up our thermostat wiring, our furnace, and our 12 volt wiring here, and then our AC voltage. So I'm gonna get all this wired up right now, and we'll kinda overview it in just a second. Something I do wanna share with you that took a little bit of troubleshooting on this, and you may run into this issue, on our old control box here, we had two wires for our furnace. We had a furnace positive and a furnace negative. And on this Advent Air, there's only one wire, and it's gonna be just the way that this box now controls your furnace. So on this one wire here, we hook this up to our furnace negative. And what that's gonna do is supply the power to our furnace, and we capped off the positive. On the other box, of course, we had the positive and the negative. But this is the way that it needs to be wired on this system. So again, this is the furnace control wire that's hooked to your furnace negative, and this is gonna kick your furnace on and off from the control box here. And then, we just capped off. If you have a furnace positive wire like that, just cap that off. We have everything wired up. I've got my AC voltage wired here with the wire nuts, and I'll end up tucking that inside the box. And then, the rest of this stuff, the thermostat wiring has been hooked up and the 12 volt wiring has been hooked up. I'm just leaving it hanging loose for right now because we need to do some work up inside the box. Namely, we're going to be installing this divider pan, so we can take off the styrofoam that came with it. Now, on most roofs, this thing's just gonna go up with no problems. If you have a thinner roof insulation-wise, this can be broken and cut along this line here for a thinner application. For us, it's gonna work just fine. What you'll see on the inside of this unit is a white tape strip along this backside. We need to take this off. This pan is gonna get installed up, and it's gonna stick to this, but we wanna compress this gasket up against the bottom part of our upper unit there. What we're doing is just making sure air on this side stays on this side, and air over here on the other side stays over there. So we're gonna put the divider up. What I like to do is kinda compress the gasket, make sure we're all the way up against the top of that unit up there. I like to use foil tape. This is not included in your kit, and this is like metal duct tape. And this foil tape, I'm gonna run this around the top edge up here and also right here, and seal this up before we put up this foam insulation. Now, this came with our kit. And what this is, this is gonna also be sticky foam, and we're gonna be applying this against the divider piece that we just put up here. What this does is it acts as a thermal barrier against the other side, and it'll just keep condensation from forming and dripping down into your RV here. This is gonna be cut to fit, and you're gonna wanna cut this to fit this whole section here, and then stick it directly to it. (tape rustling) So this was the end result over here. It's not the prettiest, I'll admit it, but we've got the foam that's insulating the divider. And I just use foil tape wherever else I saw a hole in there. This particular system is gonna be using the duct work on either side. So this is gonna be all sealed down here. So any leaks that we would've had going over here or through the partition is gonna be less air moving through our vent. So that's why I'm pretty particular about making sure that this stays insulated and sealed against the other side. Now, over here on our wall, because we we inchesre replacing a unit with a thermostat, we already had the thermostat wires run. This particular thermostat is gonna use four wires, and that's pretty common. And the four colors they're gonna be using is blue, yellow, red, and green. Now, you'll have a little diagram up here on the back telling you which wire goes where. This is gonna be the 12 volt positive, the common or negative, and then your furnace A and furnace B wires. Now, I've got all the connections on the back of our thermostat here. That's gonna complete all of the connections for our installation. Now, I've went ahead and turned on the 12 volt power and the AC power. And what I like to do is just turn everything on before tucking this away and making sure everything's gonna work properly. So I've got the fan on right now, and we're gonna turn it on. (fan humming) And that's gonna be blowing fan air straight out right now on the bottom side. This is what we want. And we can check, we'll put it on cool and have the compressor kick on. (fan humming continues) (fan humming continues) So our compressor has kicked on. We're gonna let it run for a little bit, make sure it cools down. And if that's the case, everything's working normally. I'm gonna probably take some zip ties and get these wires tucked away, get the protective shield over our AC voltage here, and then we can install the lower plenum. You need to remove the filter. (hardware clicking) And that'll expose four more of the screw holes here. Your kit's gonna come with screws and cover plates for these outer holes here. (tool whirring) Just install these. I like to start in the middle, and then end up at the four corners here. (tool whirring) With all the screws tight, you can install the blanking plugs here. (plug popping) Looks like they are oriented to where this little tab will be towards the inside corner here. (plug clicking) And then, we can reinstall the filter. This filter is washable and removable. (hardware clicking) And that was a look at some of the features and the installation of Advent Air low-profile rooftop air conditioner.
Average Customer Rating: 4.7 out of 5 stars (59 Customer Reviews)
This AC unit lets you replace an existing AC or add a new AC to your RV or camper. Low-profile design reduces wind resistance. Condensation dispersion system increases efficiency. Compatible with Advent Air, Dometic, Coleman Mach, or Carrier setups.
I purchased this 15,000 BTU unit with the direction from customer service. I was told that it was a replacement for my original Dometic AC on my 5th wheel and that it would mount and have identical wiring.
They were very helpful and correct. It was extremely easy to replace. The mounting bolts and wiring hook up were identical to my old unit. The hardest part was getting it on the roof of my camper which actually wasn’t that difficult. I put an old piece of carpet (upside down) on the roof to protect it. I used my tractor with a front loader to lift it as high as I could then just set it up on the roof.
Once I removed the diverter/trim from the inside ceiling there are 4 bolts holding the unit in place, one wiring plug and the freeze sensor attached to the evaporator. Once that was all done it just lifted off the roof. After cleaning the roof where the old unit set, I simply set the new unit on the same seal footprint. I went inside hook up the wire plug, located the freeze sensor and tightened the 4 bolts. Don’t tighten the bolts too tight, just enough to hold it tight and adequately compress the foam seal.
The overall size of the new unit is shorter and smaller than the Dometic.
So far so good, I ordered two of these to replace my existing units.
One unit arrived damaged, but is working OK.
They seem a little noiser than the Coleman Machs.
Working good so far.
I don't know about longevity however I replaced 2 Dometic Brisk 2 systems on a camper I bought that needed a little more than tlc. It is a 2 zone Dometic system and these plugged right up. Only had them in a for a few days but they work great! Very pleased. I am hoping they last. Shipping was FAST and Etrailer kept me up to date on status. They were also very helpful with questions I had to make sure they would work with my system. I think these are actually quieter than the Dometics I replaced. Not hard to install, in fact the hardest part was getting them on the roof.
So EASY it aughta’ be CHEESY!!! Unboxed AC Unit, noticed two dents in the unit but none of the parts looked damaged or inconsistent; So I decided not to call regarding minor damage, instead I decided to install it by using two ramps I made out of scrap wood. TIP: the wooden ramps made it so simple to install the unit with minimal effort and two people. This made it a breeze to put in and I really recommend using this tip when installing your unit… The New Advent AC Unit made is so simple to plug into the dometic. This unit is made for easy installation and almost a universal fit. Great Experience at this establishment and happy with their product and selection of RV and Trailer parts. I will definitely recommend to all my fellow RV’ers! Happy Shopping! Always remember… Keep your library card updated!??????
Good air conditioner, but fan won't shut off after set temperature is met
The A/C seem to be a good value and the customer service from Britney was great. It was not clear to me that this unit didn't include all of the inside the camper components and thermostat as shown in the installation video.
Much more compact and lighter than original unit and came when anticipated. This unit Beatrice made sure the crossover from Coleman to Advent was compatible and right adapter was used. Love dealing with e trailer as I can speak to real people that I can understand and know what they are talking about.
Etrailer folks were extremely helpful! Sheila thank you! The casing had some minor dents in the sides therefore I gave 4 stars. I was able to pull them back out. Advent needs better packaging in their boxes to protect the unit!
Disappointed, I called before ordering the female I talked to told me that my current metal flange and plastic distribution would work with the new Advent AC. Not really, I tried to use the existing flange it turned into a huge pain. I watched the video for the install and it seemed to me that the divider or plenum was included with the AC- Nope, this part also I think is included with the lower unit part # ACRG15 but.... the customer service rep wasn't sure a little disappointed. So now I have ordered part # ACRG15 paid more shipping! In final learn from my mistake customer service reps are not sure about want you need for a complete job, just order everything send back what you don't use.
direct replacement as advertised,easy to do, hard part is getting it on the roof, good instructions, but I youtubed it, also to make sure I was right....definaly do it again,e trailer was great staying in touch..
The Advent A/C was delivered in good physical condition. I have not installed it yet. UPS had it sitting in their truck on its end. I do not think that is good for the compressor. Hopefully it starts and runs with no issues when I install it next week. Fast friendly customer service and delivery. Thank you Etrailer.
The replacement air conditioner works perfectly. The base plate on my original Coleman was smaller, so we have to make some adjustments otherwise everything works great.
Great service! Great prices! I had a question and technician answered quickly and explained everything.
Boxes arrived intact. Was kept informed about when it would ship, that it had shipped and had arrived and where they had dropped it off.
Was truly great experience! Will recommend to my other RVing friends!
