The Mach I Power Saver is Coleman Mach's updated-generation quiet rooftop air conditioner built for RVs with standard 14 x 14 in. roof openings. It delivers 11,000 BTU of cooling capacity on just 9.5 amps at 120V AC, making it one of the lower-draw options in its BTU class -- a real advantage when running on a 30-amp service or a generator. The black shroud finish matches rigs with dark or two-tone rooflines. Ducted airflow distributes conditioned air through your existing ceiling assembly for whole-coach comfort.
Most rooftop ACs in the 13,500 BTU range pull 12 to 15 amps at startup and cruise above 11 amps running. The Mach I Power Saver trims that footprint without sacrificing real comfort -- 11,000 BTU is sufficient for coaches up to roughly 25 to 28 feet when ambient temperatures are moderate, and the lower amp draw means more headroom for other 120V appliances on the same circuit.
The R32 refrigerant used in this generation has a global warming potential (GWP) of 675 -- roughly one-third that of the R410A it replaces in this product line. R32 also operates at higher efficiency per pound of refrigerant, which contributes to the unit's compact refrigerant charge and lighter overall weight.
9.5 amps running current -- fits 30-amp service alongside other loads without tripping the pedestal breaker.
Lower GWP than R410A. Single-component refrigerant simplifies service; no mixed-gas blending concerns.
Designed to connect to a ceiling air distribution box for even, whole-coach airflow through existing ductwork.
Drops directly into any standard 14 x 14 in. RV roof opening -- the industry-standard cutout size used for decades.
Coleman Mach's lineup can be confusing because several rooftop units share similar shroud profiles. Here is where the Mach I Power Saver sits:
If your shore power situation is tight or you camp frequently on 20-amp hookups with a 30-amp adapter, the Power Saver's 9.5A draw is a meaningful advantage over the Mach 8.
The Mach I Power Saver carries forward the Quiet Series engineering from Coleman Mach -- including a two-speed fan motor and vibration-isolated compressor mount -- that reduces operational sound compared to older Mach 3 and Mach 8 units. Ideal for campgrounds where nighttime noise is a concern.
This unit is configured for ducted airflow and must be paired with a compatible ceiling air distribution box (also called an ADB or ceiling assembly). Coleman Mach ceiling assemblies are sold separately. The distribution box mates to the bottom of the rooftop unit and routes conditioned air through existing ceiling ductwork. A non-ducted (non-plenum) ceiling assembly will not distribute air properly with this unit. Confirm your ceiling assembly part number before ordering if you are replacing an existing unit.
The rooftop unit ships without a ceiling assembly, wall thermostat, or control board. If you are doing a fresh install or replacing a unit from a different manufacturer, you will likely need to source a compatible Coleman Mach ceiling assembly and a digital or analog wall thermostat separately. Buyers replacing an existing Coleman Mach unit with the same BTU class typically reuse their existing ceiling assembly and controls.
