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.
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.
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.
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.
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.
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.
