When the temperatures climb, this 15,000 Btu system gets right to work. The large coils and airflow-boosting fins pull heat out efficiently, so you feel the temperature drop within minutes. It keeps the air dry, cool, and comfortable without running all day. With a steady 12V DC draw of 13.9 amps and R32 refrigerant, it delivers serious cooling while meeting 2025 EPA regulations.
Matching parts make installation smoother. The rooftop unit and air distribution box are designed to work together, so there’s no guesswork about compatibility or wiring. Everything fits a standard 14-1/4" × 14-1/4" opening, which means you can focus on mounting and sealing instead of figuring out which parts work with which. It’s a complete system that takes the stress out of replacement or upgrade projects.
The air distribution box gives you hands-on control right where you need it. Simple knobs handle fan speed and cooling mode, while front and rear airflow dampers let you direct air exactly where it feels best. The low-profile Euro styling sits clean against the ceiling and helps cover old mounting marks from earlier units. When it’s time to clean up, the pop-out grilles make filter maintenance quick—just pull, rinse, and snap back in place.
When the temperature drops but it’s not cold enough for a furnace, this system has an easy answer. It’s prepped for an optional 5,600 Btu heat strip (sold separately) that installs quickly and takes the edge off without drawing heavy power or noise from a full heating cycle. You get extra comfort without changing anything else about your setup.
Copper tubing, secure joints, and tight seals keep the system running strong through heat, vibration, and travel wear. The textured black rooftop unit pairs with a white air distribution box for a clean look inside and out. At about 85 lbs overall, it’s sturdy but still manageable when handling rooftop installs. With a 2-year limited warranty on the air conditioner and a 1-year limited warranty on the air distribution box, it’s made to keep your space cool for many seasons ahead.

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.
