Replace your worn-out Coleman-Mach AC with a 15,000 Btu textured white rooftop unit for compatible R32 systems. It moves air through ducted or non-ducted setups, but this is the AC only, so the air distribution box and thermostat are sold separately.
When your old rooftop AC still fits the opening but does not keep the RV comfortable like it used to, replacing the outside unit may be the cleaner path forward. This Coleman-Mach Signature Mach 15 replaces the rooftop air conditioner and works with compatible Coleman-Mach R32 ducted or non-ducted interior components. The air distribution box and thermostat are sold separately, so you can match the new rooftop unit to the correct setup for your RV.
Heat can build fast inside an RV, especially after hours of sun on the roof and windows. This 15,000 Btu Mach 15 delivers 500 CFM of airflow to help move cooled air through the cabin. That extra airflow is especially helpful in ducted RV systems, where the AC has to push air through ceiling ductwork before it reaches the vents. It can also be used with compatible non-ducted Coleman-Mach interior components when your setup sends air directly into the cabin.
This rooftop AC is built for compatible Coleman-Mach systems that use R32 refrigerant. That compatibility matters because newer R32 systems are not always interchangeable with older Coleman-Mach setups. Before installing, confirm that your air distribution box, thermostat, and controls are made for this R32 rooftop unit. It is not backward compatible with older systems.
Swapping a rooftop AC means lifting the unit onto the RV, sealing the roof opening, and connecting it to the correct interior components. If you are staying with a compatible Coleman-Mach R32 setup, that can make the replacement more straightforward, but it is still a job where a second set of hands can help. If you'd like help installing your air conditioner, check out our Installer Locator to find an installer near you.
This AC can be paired with the Coleman-Mach AirSpace Heater electric heat kit , sold separately. The heat kit adds supplemental electric heat through the compatible Coleman-Mach system, which can help take the chill out of the air on cool mornings or shoulder-season trips. It is not included with this AC unit and is not meant to replace your RV furnace in cold weather.

Hi, everybody. Andy here with etrailer.com. Let's take a quick look at this Coleman-Mach Signature Mach 15 15,000-BTU RV Air Conditioner in Textured White. Now, at 15,000 BTU, this unit is going to keep even your larger rig cool without struggling on those really hot days. Now, if you've ever dealt with an undersized air conditioner, you know that that can be pretty frustrating as it never seems to get quite comfortable. So this is gonna help avoid that problem.
This medium-profile RV air conditioner is going to move high volumes of air to cool down the inside of your RV or camper very fast. Now, as you probably know, Coleman-Mach has been making RV air conditioner units for quite a long time, and this Mach line has a pretty good reputation for being both reliable and durable. This is the Signature model, which is basically more of the premium version, and they beefed up the components and added some extra efficiency to help it run smoother and last longer for you. Now, this is going to be a rooftop air conditioner only, and it's going to be compatible with both ducted and ductless systems. The rooftop unit itself, this AC, is basically gonna be the same engine whether you run ducts or not.
It's the interior assembly that's going to determine whether the cooled air gets distributed through your vents, ducted, or plunges straight down, which would be non-ducted. So you're gonna pair this with a compatible Coleman-Mach air distribution box and thermostat to complete your setup. And I do wanna point out that this is not going to be backwards compatible with any air conditioner systems from 2024 and earlier due to the new R32 refrigerant that's going to meet the 2025 EPA regulations. So if you're using this AC as a replacement and your current air distribution box and thermostat are not compliant with R32 refrigerant, you will need to replace both the thermostat and the air distribution box and any other associated components. And we do carry kits with this unit and with the air distribution box, whether it's gonna be for ducted or ductless, and the thermostat, and that will all be compliant with the R32 refrigerant.
So you can find those options here at etrailer.com. Let's talk measurements. Looking at the overall length from end to end, we're sitting pretty close to 39 inches long. The overall width, about 26 inches wide, and then the overall height, about 13-1/2 inches tall. This is going to drop into your 14-1/4-by-14-1/4-inch opening on your roof, and this weighs about 80 pounds or so.
And so this Mach Signature Series is designed with a rugged casing and heavy-duty construction. This is, as I mentioned, a textured white, so it's got a little bit of a texture to the finish. So I think it's gonna hold up really well for you. It's gonna be able to handle years of use without the usual wear and tear because of that textured white finish. It's going to help resist fading, scuffs, and dirt, so it should keep a somewhat cleaner appearance over time. While we're closer here, I did want to pull out the wiring harness here just to give you a view of that plug there. Hopefully you can see that. And you are going to have a foam base here at the bottom. And so this unit is powerful. Coleman does a pretty decent job of keeping the noise down. Now, this is not going to be like a whisper-quiet unit, but compared to older models or budget brands, it's going to be noticeably less disruptive, so you should have no problems sleeping or enjoying a movie or enjoying conversation inside of your camper or RV with this running. So like I said, this is going to be just for this 15,000-BTU AC unit, but we do have other options available, not only from Coleman-Mach but from other manufacturers as well. And you do wanna make sure that you're pairing this with an R32-compatible air distribution box and thermostat from Coleman-Mach. So if you happen to have any other additional questions that I did not cover with you today, don't hesitate to reach back out to us. Ultimately, we do wanna be sure that you're getting exactly what you want and need. But I think that's gonna wrap up our look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
