When the temperature climbs, this 15,000 Btu Coleman-Mach system keeps things under control fast. The matched rooftop unit and air distribution box move steady, dry air through the space so it actually feels cool instead of muggy. Inside, large coils and airflow-boosting fins help pull heat out efficiently while the R32 refrigerant keeps it compliant with 2025 EPA standards. You get consistent comfort that doesn’t fade when summer drags on.
If your old unit finally gave up, this complete kit makes replacement straightforward. The rooftop assembly and air distribution box are designed to work together, so you don’t waste time chasing compatible parts. It drops into the standard 14-1/4" × 14-1/4" opening most systems use, making it an easy retrofit for existing setups without ducted air.
No remote needed here—just reach up to the ceiling panel and set your cooling how you like it. The control knobs give you simple fan and temperature adjustments, and front and rear dampers let you direct airflow exactly where it’s needed. When it’s time to clean up, the pop-out grilles make filter access fast with no tools required.
Sometimes you don’t need to fire up a full furnace to take the edge off the cold. This system is prepped for an optional 5,600 Btu heat strip (sold separately) that installs easily into the existing setup. It gives you a convenient touch of heat without adding complexity or extra noise.
With copper tubing and secure joints, this medium-profile rooftop AC holds up season after season without losing its seal. It measures 38-3/16" long × 28-3/16" wide × 13-15/16" tall and weighs 85 lbs—sturdy enough for steady performance but still manageable for handling during install. The polished white finish matches cleanly with most setups while keeping the look low-profile and modern.

Haven’t installed yet but the product came in properly.
Thanks
E-trailer is the place to buy delivery purchasing everything all good the Coleman air conditioning rooftop no problems simple to install and works great
The units were in great shape as they were delivered. when I was putting in my order the screen said Sunday delivery, when I submitted the order it changed to Monday, when I tracked the order it said Tuesday. It was Tuesday that it was delivered. that is the only negative thing about my order. everything else is as ordered. I did not realize I ordered the units with the control knobs but that was my mistake. I really needed the ones with the thermostat controls. If there is a kit to switch it from the knobs to the thermostat I would love to know what it is.
Came slightly damaged but nothing that couldn’t be straightened. Unit works very well. It was certainly a positive upgrade
Excellent customer service and proper, product knowledge!
Ac unit was good the heating element did not work for that control box
It was an easy replacement for my 22 year old Coleman Mach 15 btu heat pump. The compressor was tired and noisy. I was told I couldn't use my existing thermostat
and would need to use the one supplied in the kit. This was incorrect, I made a schematic combining wire color and pin designation for operation minus heat pump. The existing thermostat operates the A/C and gas heater as before.
The new system works fine and is quiet.
What should I do with the supplied thermostat??
I've replaced several various units on various trailers and so far this has been my favorite unit to work on and seemed to blow cold the best
We received the air conditioning system quickly. I had only one issue with one of the brackets. It was bent on arrival but I was able to bend it back into shape. We installed the unit and it works great!
I wanted to wait until I used this unit before reviewing. I replaced an old dometic 13,500btu with the Mach 15, 15,000btu. WOW; it sure does it job for my smaller Wolf pup camper. So far I am pleased.
