Coleman-Mach 18
The Mach 18 is a self-contained three-part system: the 18,000 BTU variable-speed inverter unit, its own 360-degree ceiling assembly that works ducted or non-ducted, and a heat/cool wall thermostat, with nothing to cross-check. It is the quietest and lowest-current rooftop unit Coleman-Mach makes, 12.7 A at full load and 5 A in eco, and the one that runs on a small inverter generator without a soft start. Cool only; the thermostat's heat side runs your furnace. The complete kit and the individual parts are listed here.
