Features to know about

Cools the Space Fast Without Ducts: 13,500 Btu of Steady Airflow

When the temperature spikes inside, the 13,500 Btu cooling capacity and 320 CFM airflow on this Coleman-Mach non-ducted system bring it back down fast. The matched rooftop unit and air distribution box work together to move air evenly and pull heat out efficiently. Large coils and airflow-boosting fins help it stay consistent so it cools without strain or lag.

Easy Control From the Ceiling: Simple Knobs and Adjustable Dampers

You can tweak fan speed and direction right from the ceiling without searching for remotes. The control knobs are easy to reach, and front and rear dampers let you aim airflow where it’s needed most. When it’s time to clean, the pop-out grilles release without tools—just rinse the filters and snap them back in place.

A Matched Kit That Simplifies Installation: Designed to Work as a Set

Getting parts to play nice together can be a headache. This kit takes care of that by pairing a rooftop unit and air distribution box built to fit perfectly through a standard 14-1/4" × 14-1/4" opening. Because everything is designed as a complete system, installation goes smoother with fewer surprises along the way.

Keeps Up Season After Season: Durable Build With Copper Tubing

Inside, all-copper tubing and gas-flux brazed joints hold pressure tight and help it stand up to years of use. The medium-profile 38-3/16" long × 28-3/16" wide × 13-15/16" tall body keeps weight manageable at 79.5 lbs while still delivering solid cooling performance. It’s built to take the heat again and again without losing its edge.

Adds Warmth When You Need It: Optional 5,600 Btu Heat Strip Ready

On cool mornings when a full furnace cycle feels like overkill, this system is already prepped for an optional 5,600 Btu heat strip (sold separately). Plug it in for gentle warmth that takes the chill off fast while staying quiet and efficient on 12V DC power at just 16 amps in heat mode.

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.

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.
by:
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.

Do you have a question about this RV Air Conditioner?
  • 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...

  • Can Coleman-Mach Signature Mach 3 RV Air Conditioner System Install on 1 inch Thick Roof
    Hey Ryan, these are all really great questions I would love to help you with. A 1 inch thick roof will work great with the Coleman Mach # CM58RR as that is the minimum thickness that Coleman says is okay with this unit. They do not show a maximum thickness figure. For steel roof installs Coleman recommends their spring pad kit part # 8333-3871 which isn't something we carry at this time. A 14 inch square opening is perfectly fine to use with this. There isn't anything extra required...

  • Parts Needed to Install Coleman Mach 3 AC Unit for Ductless Application
    Hey Daniel, we actually have a kit that includes the Coleman unit you mentioned with the correct air distribution box for a ductless setup with the part # CM58RR which includes a thermostat as well. I am not sure who Daniel is but you can definitely send him this link and he can comment below if he has any questions! This could be installed on a 10 inch thick roof but you'd need longer bolts than what comes with this.

  • Can Multiple Coleman Mach AC Units Be Controlled By Wireless Thermostat In RV?
    Hey Brian! Yes, the WiFi Thermostat # CM46MR will work with the new ducted Coleman-Mach units like # CM52RR, # CM83RR, and # CM95RR. Since those are the ducted kits that already use a wall thermostat, that’s where this add-on thermostat makes the most sense. If you want, tell me what RV you have and how many AC units you’re planning to run. And just to be sure, the ducted units are for RVs that have AC vents in the ceiling that carry air through the coach. If your RV does not have ceiling...

  • Is It Worth Adding Electric Heater Kit To Coleman Mach AC Unit In RV?
    Hey Cheryl! Yes - if you want a little extra warmth for cool mornings, the optional heat strip # CM96RR is worth looking at with the ductless Coleman systems like # CM58RR, # CM68RR, # CM93RR. The big thing is just having the right expectation. It’s great for taking the chill off, but I would not treat it like a full furnace replacement. For a lot of spring and fall campers, though, that’s exactly the kind of extra heat they want. Cheryl, if you want, tell me what camper you have and how...

  • Coleman Non-Ducted AC Unit for 2022 Keystone Cougar With AC Bedroom Prep
    Hey Earl! As far as I know the AC prep will have 12V and 120V power wires up there on your Cougar so you don't have to run any additional wire for the installation. Coleman has a lot of options for ductless applications, and you can choose from the following based on color and capacity: -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 AC Unit For 2017 R Pod 179 That Has Ductless System Where Air Blows Out Of AC Unit
    Hey Rachel! Yes - that’s a ductless setup. If the air only blows from the ceiling assembly at the unit and there aren’t ceiling vents carrying air through the trailer, you’re looking at the right group. For a normal replacement, I’d start with the Coleman-Mach Signature Mach 3 # CM58RR. If you camp in hotter weather and want more cooling capacity, I’d step up to the Coleman-Mach Signature Mach 15 # CM93RR instead. Both are complete ductless systems, so you’re replacing the inside air box...

  • Replacing 10 Year Old AC Unit In Travel Trailer - Should I Replace Unit Or Whole System?
    Good morning Mark, at around 10 years old, I’d recommend replacing the whole system. These newer AC kits use R32 refrigerant, and newer AC components are not backward compatible with a lot of the older setups. On top of that, parts for older refrigerant systems are getting harder to find. If your trailer has ceiling vents throughout, a complete ducted system like the Coleman-Mach Roughneck Mach 3 # CM95RR is a solid option. If it does not have ceiling ducts and the air only blows out of...

  • AC Unit For 2020 InTech Flyer Explore Teardrop Camper That Sees Lots Of Rough Roads
    Good morning Chloey, for a small ductless camper that sees rough roads, I’d stay in the Roughneck line. The question is really whether you need the 13.5K Roughneck Mach 3 # CM68RR or the 15K Roughneck Mach 15 # CM88RR. Since your camper is on the smaller side and your old unit mostly kept up, the # CM68RR is probably the smarter pick. If you’ve been fighting heat and want more cooling headroom, I’d move up to # CM88RR. For comparison, the more standard-travel versions would be the Signature...

  • Which Size AC Complete Kit Is Best For 2018 Winnebago Micro Minnie 1700 BH ?
    Good morning Darnell, if you’re trying to stay practical with generator use, I’d usually start with one of the 13,500 Btu ductless systems first - either the Signature Mach 3 # CM58RR or the Roughneck Mach 3 # CM68RR. Those make the most sense if your current AC cooled reasonably well most of the time and you just need a fresh complete system. The Roughneck is just a better built unit that withstands the terrain and rough roads better, so that's up to you if you want to spend a bit more...

  • Does 2016 Casita Freedom Deluxe Need Ducted Or Ductless AC Unit?
    Hey there Rihanna, yes - that’s a ductless setup. If the air only blows from the ceiling assembly and there are no ceiling vents carrying air through the trailer, you’re in the right group. Also I double checked by looking up your travel trailer, and since it's more of a mid-sized single axle camper, that is also a giveaway that it's usually just a standard ductless ac unit. The big class AC RVs and toy haulers more commonly have the ducted vents going through the interior. For a normal...

  • Heavy Duty AC Unit For Toy Hauler RV That Goes Off Roading On Trails
    Hey Cole! For a ductless setup that sees rough roads, I’d look at the Coleman-Mach Roughneck Mach 3 # CM68RR first, or the Coleman-Mach Roughneck Mach 15 # CM88RR if you want the bigger 15,000 Btu option. The Roughneck versions are the ones that make more sense when the camper sees more vibration and harsher travel than a normal campground setup. If this were mostly highway miles and weekend camping, I’d point you more toward the Signature versions like # CM58RR or # CM93RR instead. Cole,...

  • Which Size AC Complete Setup Is Best For 2015 Jayco Jay Flight Travel Trailer Powered By Generator
    Hey Steve! If you’re trying to stay practical for generator use, I’d start by comparing the Signature Mach 3 # CM58RR and the Signature Mach 15 # CM93RR. Both run on 115/120V AC power, and the listed cooling draw is pretty close - 12.8 amps for # CM58RR and 13.9 amps for # CM93RR. So if your old 13.5K unit cooled the trailer reasonably well most of the time, I’d stay with the Mach 3 # CM58RR. If it always felt behind once summer heat set in, I’d move up to the Mach 15 # CM93RR. If you...
