Your old AC gave up in the heat. You could fix it, again, or replace it for good. This kit makes it easy: the components are matched and you get the kind of cooling comfort that helped you fall in love with your rig in the first place.
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.
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 13,500 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.
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 when the filters need cleaning, the pop-out grilles make it easy. No tools required. Just pull, rinse, and snap it back into place.
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.

Hi, everybody. Andy here with etrailer.com. Let's take a look together at this Coleman-Mach Signature Mach 3 13,500 BTU RV air conditioner system with a textured white cover. Now, as you probably know, one of the biggest headaches in RV repairs is figuring out which parts are compatible. Well, this kit's gonna help take that off of your plate. This rooftop unit comes with this air distribution box and they're designed to work together, so installation's going to be a whole lot smoother and nothing should catch you off-guard.
Whether you're doing the install yourself or you're paying someone else to do it, having everything designed as a set that works together is gonna make your job faster, cleaner, and less stressful. This is made for RVs without ducted air, so it's gonna be perfect if you're replacing an old setup or if you're adding a second unit to cool a separate space. And with 13,500 BTUs of cooling power, you're gonna feel the temperature shift within minutes, not hours. Inside the unit are large coils and airflow-boosting fins that are gonna help pull heat out efficiently, so your RV's gonna stay cooler with less strain on the system. And you're gonna walk in, and that air's gonna feel nice and dry and cool and breathable.
And you're gonna get a good night's sleep as well, because that air is gonna be very comfortable. So, looking at the overall measurements of our unit, the overall length from end to end is about 39" long. The overall width is about 26" wide, and then the overall height is gonna be right at about 13 1/2" tall, so this is considered a mid-profile air conditioner. This is going to work with opening sizes on your roof that are 14 1/4" long by 14 1/4" wide, and this weighs about 75 pounds or so. And then, giving you a closer look here on this side of the table, this does include this air distribution box that's going to give you full control right at ceiling level with the simple knobs, here, so you're not gonna have to worry about thermostats or digging around for remotes or climbing over furniture or anything like that.
You're gonna be able to direct the air flow as well where you need it with these levers, here, or these knobs. You've got your fan control knob, you've got your temperature control knob, here. And then, we also have these pop-out grilles here that are going to allow you to wash out the air filters. The air filters are reusable. So, everything that you need to get set up inside and get that air directed where you want it in that space.
Now, looking at the measurements of our air distribution box, the overall width is sitting pretty close to 20 3/4". The overall length is going to be about 21 3/4". And this is going to hang down from your ceiling about 2", 2 1/2" or so, so it's not gonna take up a whole lot of head space. Now, this unit is not going to be backwards-compatible with any AC system from 2024 and earlier due to the new R-32 refrigerant that meets the 2025 EPA regulations. This does use the new R-32 refrigerant. That's why this kit is good, because everything's designed to work together. It's gonna work with the R-32 refrigerant. But if you have any other components that currently, that are not compliant with the R-32 refrigerant, this will not be backwards-compatible with that, just so you're aware of that. Now, sometimes it's not cold enough to actually kick on your furnace, but it might be just a little bit chilly and you need something to take the edge off of that cool air. So, you can pick up a heat strip for this unit separately. And that's just gonna be a simple way, as I mentioned, to take the edge off of those cool mornings, but it's not cold enough to kick on your furnace. So, if you're interested in checking out that heat strip on your screen, I am including the item number, there. You can just take the item number and pop it in the search field of our website. That will take you to that heat strip and you can add that to your order. It's gonna be a pretty simple install in this unit. Now, if you happen to have any other additional questions, don't hesitate to reach out to us. We do wanna make sure that you're getting exactly what you want and need. For instance, we do have this kit available with a 15,000 BTU unit instead of this 13,500. So, if you have any other additional questions, we wanna make sure that we've answered them and you get exactly what you want. 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.
