Features to know about

Keeps the Heat Off All Day: 13,500 Btu Cooling Power

When the afternoon heat builds up, this 13,500 Btu system keeps things comfortable. The large evaporator and condenser coils pull heat out efficiently while the R32 refrigerant keeps operation in line with 2025 EPA standards. Steady 320 CFM airflow pushes cool air through every vent, so the whole space feels evenly chilled without hot spots or drafts.

Simplifies the Upgrade Job: Complete Ducted System Kit

Upgrading an older cooling setup can be a guessing game, but this matched kit takes that out of the equation. The rooftop unit, air distribution box, and single-zone digital thermostat are all designed to work together, so installation is straightforward and performance stays balanced. With an opening size of 14-1/4" x 14-1/4" and a total weight of 79.5 lbs, it fits right into a standard roof cutout without surprises.

Easy Control Right Where You Need It: Ceiling-Level Access

You don’t have to search for a remote to stay comfortable. Simple knobs on the air distribution box let you adjust fan speed and temperature from ceiling height. Open the louvers for direct airflow into the cabin or close them to send cool air through your ducts. The EZReach filter system makes cleaning quick—just pull the washable filter down, rinse it off, and snap it back into place.

Adds Warmth on Cool Mornings: Heat-Ready Design

When the temperature dips but it’s not cold enough for a furnace, this system can take the edge off. It’s prepped for an optional 5,600 Btu heat strip (sold separately) that installs easily and gives you extra comfort without heavy power draw or extra noise. It’s a simple way to stay cozy between seasons without adding another appliance to your setup.

Built to Last Through Every Season: Durable Construction

All-copper tubing and gas-flux brazed joints help this unit stay sealed and reliable year after year. The textured white housing and medium-profile design keep it looking clean while holding up against weather and road wear. With limited warranties of 2 years on the air conditioner, and 1 year each on the distribution box and thermostat, it’s made for dependable performance season after season.

Video Transcript for Review of Coleman-Mach RV Air Conditioners - Signature Mach 3 RV AC System Textured White - CM23RR

Hi everybody. Andy here with etrailer.com. Let's take a look at this Coleman-Mach Signature Mach 3 13,500 BTU ducted RV air conditioner system in this textured white cover. Now, as you probably know, one of the biggest headaches in RV repairs is figuring out which parts go together, which parts are compatible. This kit is going to take all that off of your plate. The rooftop unit, that comes with this air distribution box and a thermostat.

So everything is designed to work together, so installation's going to go a whole lot smoother. Setup's gonna be a lot more reliable. So whether you're doing the install yourself or you're paying someone else to do it, having everything together in one kit that's designed to work together is gonna make the process a lot faster and less stressful. So this is made for RVs with ducted air and with 13,500 BTUs of cooling power, the system's gonna move air through your ceiling ducts to bring the temperature down quickly and evenly throughout the space without blasting you in the face or leaving dead spots near the bed. So inside the unit are large coils and airflow boosting fins that are gonna help pull the heat out efficiently so your RV stays cooler with less strain on the system.

You're gonna walk in, the air's gonna feel great, dry, cool, more breathable, and you're also going to enjoy a better night's sleep as well with that nice, cool, comfortable air. Let's talk measurements. The overall length of this unit from end to end, we're sitting right at about 39 inches long. Then the overall width, 26 inches wide. And this is considered like a mid-profile air conditioner unit.

So the height's about 13 and 1/2 inches tall. This is going to install on your 14 and 1/4 inch by 14 and 1/4 inch opening on your roof. And this unit weighs about 80 pounds. Now, taking a closer look here at what's included, we've got this air distribution box. It's going to give you direct or ducted airflow.

So you're going to open the louvers for cool air straight down into the cabin and then you can close them to push the air through your existing duct work in your RV or camper. And then these easy reach grills are going to pop open so you can remove and rinse the washable filters, keeping air moving efficiently. And this has a low profile design. So lemme go ahead and just kind of show you what this is going to look like when it's installed in your ceiling. So it's really not going to take up a bunch of headroom in your camper. This is going to stick down maybe about an inch and 1/2 or so. And just to give you some further measurements, looking at the overall width, about 19 inches wide, the overall length, right at 20 inches long. I just wanted to flip this over to give you a view of the backside of it. So as you can see at the bottom of my table there, this does include the hardware here. So you're gonna get this frame, you're gonna get the bolts to install the air conditioner wiring, the control box here as well. This is basically the brains of the operation. And then you are going to get this thermostat. This does feature easy temperature control. This simple digital thermostat's gonna let you adjust settings on this air conditioner unit, 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. This is about four inches tall, two and 1/2 inches wide and about one inch thick. So again, everything is going to be included with this kit as you see it here. And I do wanna point out that this is not going to be backwards compatible with any AC system from 2024 and earlier due to the new R32 refrigerant. This air conditioner does use that R32 refrigerant. So that's what's nice about getting this kit because everything is designed to work and be compliant and work together with that R32 refrigerant. So if you have any other components in your camper, RV, air conditioning wise that's not compliant with that R32 refrigerant, this system is not going to work with those components. It's not gonna be backwards compatible, just so you're aware of that. This also does have the ability to have a heat strip installed separately. So if you're looking to kind of take the chill out of the air, it's not cool enough to kick your furnace on, but maybe some warnings just have that bite in the air. You can pick up this heat strip separately to install to take that chill out of the air. So on your screen, I am including the model number. You can just take that number and pop it in the search field or our website. That will take you to that strip and you can add that to your order. I can't remember if I mentioned it or not, but this cover does feel pretty strong and durable. I don't think it's gonna crack or break easily. It's not like hard or brittle or anything like that. So I think it's gonna hold up well for you. But if you happen to have any other additional questions, whether it's about this system or 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. 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.

Product arrived in 2 shipments. Upon arrival checked for damage. None noticed. Upon removal from box found small crack in cover at bottom not far from screw attachment. Most likely from shipping. This was cosmetic and would not effect function of unit. Installed unit wired and tested. Temperature reached 67 degrees in rv in about 4 hours. Much better than the 98 degrees prior to installation.

I’ve ordered many things from trailer and they have never let me down. Easy to order, fast shipping, right on time. Actually, it arrived a day early. Nice surprise.

Just got this Coleman-Mach 3 RV AC 13.5K BTU roof air conditioner installed this morning. Replaced a 16 year old non-functioning 15K Coleman. Works fine cooling a 1999 Avion 5V 38ft. 5th wheel. Single air with ducted system. Dual pane glass windows and super thick insulation. Unit is located at 7800 ft of elevation in the White Mountains of AZ. It will perform nicely in these conditions. Easy to operate rotary digital thermostat got rewired at the same location as the old switch and slide control unit. Running nicely. Thank You Will at trailer for a very smooth transaction and fast delivery! Great mobile techs did a super clean and efficient install. Shoutout to David's RV Service out of Lakeside AZ.

  • 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...

  • Can Coleman Mach AC Replace Dometic AC on 2016 5th Wheel Trailer
    Hey Jeff! The Coleman-Mach Signature Mach 3 can replace the old Dometic AC on your 5th wheel. Since these are new R32 units and that will be an old R410A AC complete replacement is required. You can choose from the following based on the color you want and if you have a ducted/ductless setup: -Coleman-Mach Signature Mach 3 RV AC System - Ductless - 13,500 Btu - Textured White # CM38RR -Coleman-Mach Signature Mach 3 RV AC System - Ductless - 13,500 Btu - Polished White # CM58RR -Coleman-Mach...

  • Replacement R32 AC System for a Coleman Mach 3 Power Saver 48208-9660
    Hey Arron, thanks for the information! Your Coleman Mach 3 48208-9660 has the older 410a refrigerant in it so the Coleman-Mach Deluxe ChillGrill Air Distribution Box you were looking at, is not going to be compatible. In 2025 the EPA mandated the new R32 refrigerant for RV AC's. The problem with all the new R32 components is they're not backwards compatible with any 401a units like your Coleman Mach 3. I do not have any air distribution boxes that are going to work with your AC system. My...

  • Can Coleman Mach 3 Tie Into Dometic Thermostat on 2022 Keystone Premier 29BHPR
    Hey Michael! I'm assuming that Dometic unit is original to your 2022 Premier. Based on the year that is going to be an R410A unit. If you're adding a Coleman-Mach Signature Mach 3 like # CM23RR it will be a new R32 unit following the 2025 EPA regulations. R32 is not compatible with R410A parts so the Dometic thermostat will not be compatible with the new AC unit and there is no way to adapt it. You will need to install the full system, with the thermostat, and run them separately unless...

  • Does Coleman Mach 3 RV AC Unit Have Ability to Control RV Furnace
    Hey Russel, the thermostat that comes with the Coleman-Mach Signature Mach 3 RV Air Conditioner System # CM23RR that you referenced does have ability to control a furnace like you have so it would work great. The connectors on this are different from what you would now though so your current wiring would not be able to be reused. What furnace do you have in your RV?
