Features to know about

Cools Down Fast in Hot Weather: 13,500 Btu of Steady Airflow

When the temperature climbs, the 13,500 Btu cooling capacity gets the cabin feeling comfortable again. Large coils and airflow-boosting fins pull heat out efficiently so you can feel the air shift within minutes. With 320 CFM of airflow and R32 refrigerant that meets 2025 EPA regulations, it keeps things cool without working overtime.

Simplifies Replacement Installs: Matched Rooftop Unit and Air Distribution Box

No need to hunt for compatible parts or fight through guesswork. The rooftop unit and air distribution box are built to work together, giving you a complete system that installs cleanly into a 14-1/4" x 14-1/4" roof opening. Whether you’re replacing an older Dometic or Coleman-Mach setup, this matched kit makes it easier to get everything connected and running right away.

Easy Ceiling-Level Operation: Direct Controls and Adjustable Dampers

The air distribution box puts full control within reach. Simple knobs let you adjust fan speed and cooling directly at the ceiling, while front and rear dampers direct airflow where it’s needed most. When the filters need attention, the pop-out grilles make cleaning quick—just remove, rinse, and snap back in place.

Comfort When Mornings Turn Chilly: Heat-Ready Design

When it’s too cool for comfort but not cold enough for the furnace, this system’s heat-ready design has you covered. It’s prepped for an optional 5,600 Btu heat strip (sold separately), giving you an easy way to take off the morning chill without extra gear or complicated wiring.

Built to Last on the Road: Durable Construction and Balanced Profile

All-copper tubing with gas-flux brazed joints helps it stay sealed and reliable season after season. The medium-profile rooftop unit measures 38" long x 28-1/16" wide x 13-13/16" tall and weighs 79.5 lbs, keeping weight balanced while still covering older ceiling imprints for a clean look. It’s a solid upgrade that keeps comfort simple trip after trip.

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...

  • 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...

  • Soft Start for Coleman-Mach Signature Mach 3
    Hey Curtis, welcome back! You can use the Soft Start Kit for Coleman-Mach RV Air Conditioners # CM56RR with the Coleman-Mach Signature Mach 3 # CM38RR. This is specifically designed for Coleman-Mach systems and will reduces start-up amperage by up to 75%. Are you replacing your older Coleman-Mach system with the # CM38RR, or are you planning to use it with your existing setup?

  • Does Coleman Mach AC Unit Come With Gasket And Heating Element And Thermostat?
    Hey there Jordan! The Coleman-Mach Signature Mach 3 RV Air Conditioner System - Ductless # CM38RR does indeed come with the gasket necessary for installation. There is no thermostat on the wall as you mentioned, so you just use the controls on the ac distribution box. Then for the heat strip you will want to add Electric Heater Kit for Coleman-Mach # CM96RR since it's not included. That should get you taken care of! Is there anything else you had questions about? And do you have any...

  • 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...
