This setup brings real cooling power when the temperature climbs. The 15,000 Btu rooftop unit pushes strong airflow through the ceiling ducts, dropping the heat quickly and keeping larger interiors comfortable. It runs on 12V DC with a cooling amperage of 13.9 amps and uses R32 refrigerant to meet 2025 EPA regulations, so it’s efficient while keeping performance high.
The ducted design moves cool air evenly through your vents, but you can also open the louvers on the air distribution box to get direct airflow right where you are. It’s an easy way to fine-tune comfort without extra gadgets or remotes. The slim box keeps overhead space open, and the EZReach filter system makes cleaning quick—just pull it down, rinse it, and snap it back in.
Figuring out what pairs with what can be a pain. This complete kit takes care of that by including a rooftop unit, air distribution box, and single-zone digital thermostat made to work together. Everything lines up with the standard 14-1/4" × 14-1/4" roof opening for a smoother install and dependable operation once it’s in place.
When mornings feel a little too cold for comfort, this system is ready for an optional 5,600 Btu heat strip (sold separately). It’s a simple add-on that brings gentle warmth without firing up a furnace or pulling heavy power. With cooling and heat capability in one setup, it keeps your space livable across more seasons.
The textured white rooftop unit stands up to weather and vibration while holding its seal season after season. It measures 39" long × 26" wide × 13-1/2" tall and weighs 85 lbs. The air conditioner carries a 2-year limited warranty, and the air distribution box and thermostat each have a 1-year limited warranty—coverage that shows it’s made to keep going trip after trip.

I'm glad to hear you were able to get everything up and running and that the new Coleman-Mach is working well and much quieter for you, William! Since the thermostat was included with the # CM32RR system and you were able to configure your existing thermostat to operate the A/C and furnace, I would hang onto the supplied thermostat as a spare. I am shocked to hear that your original thermostat, we have been told by most of the AC manufacturers that the new R32 thermostat has to be installed, so this is nice to know.
