Features to know about

A Matched Kit That Simplifies the Install

One of the biggest headaches in RV repairs is figuring out which parts are compatible. This kit takes all that off your plate. The rooftop unit and air distribution box are made to work together, so installation is smoother and nothing catches you off guard. Whether you're doing the install yourself or paying someone else to do it, having everything designed as a set makes the job faster, cleaner, and less stressful.

Consistent, Ductless Cooling

If you've ever had an AC that ran all day and still left the rig feeling muggy, this one's a different story. It's made for RVs without ducted air, so it's perfect if you're replacing an old setup or adding a second unit to cool a separate space. And with 15,000 Btu of cooling power, you'll feel the temperature shift within minutes, not hours. Inside the unit, large coils and airflow-boosting fins help pull heat out efficiently, so your RV stays cooler with less strain on the system. You walk in, and the air feels dry, cool, and breathable - like a good night's sleep is actually possible again.

Easy, Accessible Control at the Ceiling

The air distribution box gives you full control right at ceiling level, with simple knobs you can reach without digging for remotes or climbing over furniture. You can direct airflow where you need it with adjustable dampers, and the low-profile, Euro styling helps cover old ceiling imprints from earlier setups. When the filters need cleaning, the pop-out grilles make it easy. No tools required. Just pull, rinse, and snap it back into place.

Add Heat for Chilly Mornings

Sometimes, it's not cold enough to run the furnace, but it's too chilly to be comfortable. This system is prepped for a 5,600 Btu heat strip (sold separately), which is a simple way to take the edge off on those in-between mornings. It's easy to install and helps your space warm up without the noise or power draw of a full furnace cycle.

Video Transcript for Review of Coleman-Mach RV Air Conditioners - Signature Mach 15 RV AC System Textured White - CM43RR

Hi, everybody. Andy here with etrailer.com. Let's take a look together at this Coleman-Mach Signature Mach 15, 15,000 BTU RV air-conditioner system with this textured white cover. Now, as you probably know, one of the biggest headaches in RV repairs is figuring out which parts are compatible, which ones go together. But this kit's gonna help take all that off of your plate. This rooftop unit comes with this air distribution box, and they're designed to work together, so installation should be smoother and nothing's gonna catch you off guard.

So whether you're doing the install yourself, or you're paying someone else to do it, having everything designed to work together as a set or as a kit, should make your job a whole lot easier, cleaner and less stressful. Now this is made for RVs without ducted air, so this is gonna be perfect if you're replacing an old setup or you're adding a second unit to cool down a separate space. And with 15,000 BTUs of cooling power, you're gonna feel the temperature shift within minutes. So you're not gonna have to wait hours for this to cool down the inside of your RV or camper. Inside of the unit are large coils and airflow boosting fins that's gonna help pull heat out efficiently, so your RV's gonna stay cooler with less strain on the system.

You're gonna walk in and immediately feel that nice cool dry air. It's gonna be breathable, and you're gonna get a good night's rest as well because it's gonna be comfortable inside. This cover is kind of a textured plastic cover. It feels very durable. I think it's gonna hold up really well for you.

So it's gonna do a great job of protecting the internal components from water, dirt, debris and things like that. Let's talk measurements. The overall length of this unit end to end is about 39 inches long. The overall width is about 26 inches wide, and the overall height is right at about 13 and a half inches tall. So this is considered like a mid profile air conditioner.

This is gonna work with opening sizes on your roof that are 14 and quarter inches long by 14 and a quarter inches wide. And this weighs about 80, 85 pounds. Now taking a look at this side of my table here a little bit closer, this air distribution box is gonna give you full control right at ceiling level with the simple knobs that you see here. So you've got the knob for fan speed and the knob for temperature setting. So you're not gonna have to worry about digging for remotes or climbing over furniture, and you're gonna be able to direct the airflow where you want it with the adjustable dampers. And then we also have these pop up, or pop out rather grills, that are gonna make it very easy to clean out those air filters. And you will get this hardware here that's included to get this mounted into place. And the bolts, of course, will secure the air conditioner inside of your RV. So everything that you're gonna need here to get this mounted into place. If you're wondering about the measurements of the box itself, looking at the width, we're sitting at 20 and three quarters inches wide. The overall length is about 21 and three quarters inches long. And this is going to be sticking down from your ceiling about two, two and a half inches or so. So it's not gonna take up a whole bunch of head space in your camper. And I do wanna point out that this system is not going to be backwards compatible with any AC systems from 2024 and earlier due to this unit using the new R32 refrigerant that meets the 2025 EPA regulation. So that's why getting a kit like this is gonna be great because everything here is designed to work with that new R32 refrigerant. If you have any other components that are not designed to work with that R32 refrigerant, then it will not be compatible with this. Now this will not be backwards compatible. So just so you're aware of that. Now, sometimes it's not cold enough to run your furnace, but it can be a little bit too chilly to be completely comfortable. So this system is prepped for a heat strip that we do sell separately and it's gonna be a simple way to take the edge off of those mornings that can be kind of chilly. So if you're interested in taking a look at that heat strip, on your screen, I am including our model number. You can just take that number, pop it in the search field of our website, that will take you to that strip, and you can add that to your order. It should be a pretty simple install. And we do carry this kit, this system with a 13,500 BTU air conditioner unit over this 15,000. So if you're looking for something a little bit less than 15,000 BTU, we do have that option available. But all that to say, if you have any other additional questions, 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. 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.

E-trailer is the place to buy delivery purchasing everything all good the Coleman air conditioning rooftop no problems simple to install and works great



by:

The units were in great shape as they were delivered. when I was putting in my order the screen said Sunday delivery, when I submitted the order it changed to Monday, when I tracked the order it said Tuesday. It was Tuesday that it was delivered. that is the only negative thing about my order. everything else is as ordered. I did not realize I ordered the units with the control knobs but that was my mistake. I really needed the ones with the thermostat controls. If there is a kit to switch it from the knobs to the thermostat I would love to know what it is.

  • Difference Between Coleman-Mach Roughneck Mach 15 and Signature Mach 15
    Hey Bill, great question! The Signature Mach 15 is your standard AC unit which is probably what you want. The Roughneck has a fortified interior making it ideal for off-road and heavy industrial vehicle applications. Basically it is made to take more of a beating. If you had an old carrier and it is wearing out from use over time (I'm guessing that is the case here) the Signature is what you want. If you have been off-roading with your trailer lately and it killed off the Carrier then...

  • Replacement for Coleman-Mach AC on Travel Trailer
    Hey Kyle! You can replace your old Coleman-Mach AC with one of the new ones. However, you will need to replace the thermostat and air distribution box as well. All of the new AC units use R32 refrigerant following the 2025 EPA guidelines so any old R410A components aren't compatible. We have 13,500 Btu or we have the 15k units if you want to upgrade. You can choose from the following based on color and ducted/ductless: -Coleman-Mach Signature Mach 3 RV AC System - Ductless - 13,500 Btu...
