Features to know about

Replaces a Worn-Out Coleman-Mach Rooftop AC

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.

Strong Airflow for Hot Cabins and Ducted Runs

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.

Designed for Compatible R32 Systems

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.

Installation Help When You Need It

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.

Optional Heat Kit for Cooler Mornings

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.

Video Transcript for Review of Coleman-Mach RV Air Conditioners - Signature Mach 15 RV AC Polished Black - CM79RR

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 with this Polished Black Cover. Now, at 15,000 BTUs, this is going to give you about 10 to 12% more cooling power than a 13,500-BTU unit, so it's gonna be helpful in those larger RVs and campers that are about 30 feet long and longer. It's gonna be great for campers that have slide-outs, and this is gonna be great for those hot, humid climates where that extra capacity that's going to help keep your RV or camper more comfortable. Now, as you probably know, Coleman has been making RV air conditioning units for quite some time, and this Mach line has a reputation for being both reliable and durable. This is a Signature model, which is basically the more premium version.

They've beefed up the components and added some efficiency to help it run smoother and last longer. Looking at some measurements here, beginning with the length just roughly from front to back, we're sitting pretty close to about 39 inches long, and the overall width, about 28 inches wide. And then this is considered a mid or medium-profile air conditioner, so the height is pretty close to 14 inches tall. And this is going to work on the standard opening size of your camper or RV's roof, 14 1/4-inch by 14 1/4-inch, and this unit weighs about 80 to 85 pounds. So, this is a rooftop unit only.

This is gonna be compatible with your ducted and ductless systems in your camper or RV, but that all of course is determined on the air-distribution box that your camper uses. So, whether your air gets distributed through the vents, that's gonna be a ducted system, or if the air just plunges straight down, that's gonna be a non-ducted system. You're gonna pair this with a compatible Coleman Mach Air Distribution Box and thermostat if needed to complete your cooling setup. Now, I do wanna point out that since this uses the new R32 refrigerant, which is gonna meet the 2025 EPA regulations, this unit will not be backwards-compatible with any air conditioning components or systems from 2024 and earlier. So, you will need to make sure that your air-distribution box, and your thermostat and all other components are compliant with that R32 refrigerant.

We do offer this unit as a complete kit, either for your ducted or ductless system, so you can find those options here at etrailer.com, or you can give us a call just to make sure that you're going to be directed in the right direction. So, this Mach Series Signature Series Air Conditioner is designed with a rough casing, a rugged casing rather, and this has heavy-duty construction, so it's going to handle years of use without the usual wear-and-tear issues. And, as you can see, this is a pretty streamlined, aerodynamic-looking cover here, shroud, and so it's going to help reduce drag. And you can see that this is considered a polished unit, so the sides here kinda have a polished look along with the front, and then the top here is more of a matte, textured surface. And it's a softer cover, so I think it's going to handle impacts better than the more rigid or hard cover, so it's slightly different than what I'm used to, but I think it should hold up pretty well for you.

And this does have, I wanted to show you the wiring harness here real quick just to give you a good view of that. So, lemme pull that out from the bottom here, so hopefully you can get a good look at that. Actually, let me drop down to a closer view here. There we go. Just so you can get a good view of that plug there, and then that's gonna plug into your air-distribution box. So, for a powerful unit at 15,000-BTU, Coleman does a nice job of keeping the noise down. This isn't necessarily considered a whisper-quiet unit, but compared to older models or budget brands, this is gonna be noticeably less disruptive, so that means you're gonna be able to sleep, relax, or watch a movie without having to shout over the air conditioner. So, again, if you realize that you need more than just the unit, you need the complete kit, again, you can find those kits here at etrailer.com with this unit or with other units. But feel free to reach back out to us because we do wanna make sure that you're getting exactly what you want and need. Well, 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.

The first AC was received damaged. It must have taken a hard hit somewhere along the way and the plastic tabs for the condenser fan shroud were broken. The chassis was bent in the center, metal buckled; and the rear mounting holes for the cover were bent out of place. I had to return and have another shipped. This was certainly a hassle I hadn't planned on. This required purchasing and using nylon filament tape in place of the plastic straps I had to cut off. Big, not easy to move around, so I had to call friends to help. Beyond that, the people were all nice to deal with, no issues there. Breanna B [email protected] was excellent; very helpful. They said it could take up to 2 weeks to receive the refund, so don't expect Amazon speed, they're in no gush. I have no problems dealing with them again, but something as large as the AC, I would try to source locally even at a greater cost. The returning and waiting for the credit (still am at the time of this writing) is too much for me.
