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 that off your plate. The rooftop unit, air distribution box, and thermostat are made to work together, so installation is smoother and the setup more reliable. Whether you're doing the install yourself or paying someone else to do it, having everything in one kit makes the process faster and less stressful.

Cooling Power for Bigger Spaces

With 15,000 Btu of cooling power, this system moves air through your ceiling ducts to cool larger RVs or drop the temperature fast in smaller ones. You'll feel the temperature shift within minutes, not hours, so your RV stays comfortable even in the middle of summer.

Easy, Accessible Control at the Ceiling

The air distribution box gives you control right at ceiling level. Open the louvers for direct cooling into the cabin or close them to push air through your ducts. The slim, low-profile design leaves you with more overhead clearance inside, and the swing-open grille makes it easy to reach and wash the filter. No tools needed. 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 AC System Textured White - CM32RR

Hi everybody, Andy here with etrailer.com. Let's take a look at this Coleman-Mach Signature Mach 15 15,000 BTU Ducted 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 with each other. But this kit is going to take all that off your plate. This rooftop unit includes this air distribution box and thermostat that are all designed to work together. So the installation is gonna be smoother and the setup is gonna be more reliable.

Now, whether you're doing the install yourself or you're paying someone else to do it, having everything in one kit is gonna make the process a lot faster and a lot less stressful. So this is made for RVs with ducted air and with 15,000 BTUs of cooling power, the system is gonna move air through your ceiling ducts to cool those larger RVs or drop the temperature down a whole lot faster in smaller RVs or campers. So, you're gonna feel the temperature shift within minutes, not hours, and your RV or camper's gonna stay comfortable even in the middle of the summer. Inside of this unit, there 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.

So you're gonna walk in and that air's gonna feel dry, cool, and breathable, and your sleep is gonna be a lot better as well. This cover, as I mentioned, is textured, so I think it's gonna hold up really well for you. I think it's going to do a great job of protecting those internal components from water, dirt, debris, and things like that. So talking measurements, look at the overall length of our unit end to end, about 39 inches long. The overall width, about 26 inches wide, and this is considered like a mid-profile air conditioner, so it's about 13 1/2 half inches tall.

And this is going to work with opening sizes on your roofs that are 14 1/4 inches long by 14 1/4 inches wide. This unit itself weighs about 80 or so pounds. And then moving over to this side of the table, giving you a closer look here, this does include an air distribution box that's going to give you direct or ducted airflow. So you'll open up the louvers here for cool air straight down into the cabin, and then you'll close them to push that air through your existing ducts in your unit. And these easy-reach grills are going to pop open so you can remove and rinse out the washable filters.

That's gonna help keep the air moving more efficiently. And this has a low profile design. Let me actually go ahead and just kind of show you here. So kind of like this is what it's gonna look like on your ceiling. So you can see it's really not going to stick down far from the ceiling. It's probably gonna stick out, stick down about 1 1/2 inches or so, and just giving you some other measurements while we're talking measurements. The overall length is gonna be right at 20 inches. The overall width is gonna be 19 inches. Hardware is included along with this control box, as you can see here. So you're gonna get what you need here to get this installed in place, along with the wiring and the bolts to get the air conditioner mounted and connected to the air distribution box. And then talking about other things that are included, you are going to get this thermostat. This features easy temperature control. The simple digital thermostat's gonna let you adjust the settings on this air conditioner. It has a clear backlit display. The screen's gonna be easy to read day or night, so you're not gonna be fumbling with buttons in the dark. And just so you have a good idea of the size of this thermostat, this is about four inches tall, 2 1/2 inches wide, and about an inch thick. Now, something I wanted to let you know about this system is this is not going to be backwards compatible with any air conditioner system from 2024 and earlier due to the new R-32 refrigerant that this air conditioner has to meet the 2025 EPA regulations. So that's why getting a kit like this is gonna be great because all the pieces here are designed to work with this R-32 refrigerant. So if you have any other components that you currently have that are not compliant with the R-32 refrigerant, that will not be compatible with this system, this system will not be backwards compatible. Just so you're aware of that. I do also wanna let you know that you can pick up a heat strip separately that's going to install in this unit. That's just gonna help take the edge off of the cooler mornings. It's not a replacement for your furnace, but just something additional to just take the coolness out of the air if it's not cold enough for your furnace. So, if that's something you're interested in, I am including the item number there. You can just take the item number, pop it in the search field over on our website. That will take you to that heat strip, and you can add that to your order if you so desire. Now, if you happen to have any other additional questions about this system or any other systems that we carry, don't hesitate to reach back out to us. 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.

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.

  • 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...

  • 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...

  • Can Furrion Chill HE Replacement AC Replace Coleman Mach 8 in 2020 Vanleigh Beacon
    Hi Jake; the Furrion Chill HE Replacement RV Air Conditioner for Coleman Setup # FR32PV is an old kit that is on its way out. We no longer recommend replacing just the AC unit, and can't guarantee this will work as a plug and play replacement. We have had customers in the past successfully swap them out, others have found the connector doesn't work, sometimes the systems don't work together, and occasionally mixing up the AC with other components burns out the air distribution box (ADB)....

  • How Does Coleman Mach 15 Compare to Furrion Chill Cube
    THey Brian, the Coleman Mach Signature Mach 15 part # CM32RR is a really solid AC unit. As far as how it compares to the Furrion Chill Cube # FR69TD it only has the advantage of working more consistently with furnace controls. Aside from that the Chill Cube wins in terms of cold air blowing, quietness, and amperage draw. If you'd be open to it the best setup would be a Chill Cube and then a furnace only thermostat like the part # DMC84RR. Does running a second thermostat work for you at...

  • Can Coleman-Mach AC Replace Dometic Duo-Therm on 2014 Forest River Travel Trailer
    Hey Earl! Yes, the Coleman-Mach Signature Mach 15 AC system can replace your old Dometic Duo-Therm. These are new R32 refrigerant units (everything is as of 2025) so a complete replacement will be necessary. You can choose from the following based on ducted/ductless and the color: -Coleman-Mach Signature Mach 15 Air Conditioner System - Ductless - 15,000 Btu - Textured White # CM43RR -Coleman-Mach Signature Mach 15 Air Conditioner System - Ductless - 15,000 Btu - Polished White # CM93RR -Coleman-Mach...
