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.
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.
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.
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.
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.
Ratings & Reviews
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.
