When the temperature inside starts climbing, this 15,000 Btu system gets right to work. It moves air through your ceiling ducts to cool the space evenly and drops temps in minutes instead of hours. The R32 refrigerant keeps it efficient and compliant with 2025 EPA regulations, so you get strong performance without wasted energy.
Getting the right parts to work together can be a headache. This kit solves that by pairing a rooftop unit, air distribution box, and thermostat that are made to match. It fits a standard 14-1/4" × 14-1/4" opening and includes clear instructions to make setup straightforward and reliable whether you’re doing it yourself or helping someone else install it.
No need to reach for a remote or climb over furniture. The air distribution box gives you direct control with easy-to-grip knobs right where you can reach them. Open the louvers for cool air straight into the cabin or close them to send air through ducts. The slim 1-1/2" thick box keeps overhead space open, and the swing-open grille lets you pull and rinse the EZReach filter without tools.
When it’s not cold enough for the furnace but still chilly, this system is set up for an optional 5,600 Btu heat strip (sold separately). It adds gentle warmth without a big power draw or noise, making early mornings and late nights more comfortable.
The textured black rooftop unit and white air distribution box are made with quality materials that hold up through heat, road vibration, and time. With voltage rated at 12V DC and amperage draws of 13.9 amps (cool), 16 amps (heat), and 18 amps (desert), it delivers consistent cooling power while staying dependable 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.
