Coleman-Mach 8 Plus Ultra-Low-Profile RV Air Conditioner | 13.5K & 15K

The lowest rooftop you can buy that still out-cools the tall ones. The Coleman-Mach 8 Plus uses two motors so it delivers the same BTUs on low speed as on high — full cooling with the quiet fan at night — and a robust one-piece fan-motor/blade venturi design that cuts outdoor fan noise by more than 5 dB. The industry-exclusive fiberglass base pan is stronger and lighter than steel, the ultra-low aerodynamic profile trims drag and clearance, and a built-in 100% condensate removal option keeps the drip off your sidewall.

⚠️ Decoding Mach 8 Part Numbers

PartsVia lists these by part number only. Coleman's numbering: 372xx = cooling only, 370xx = heat pump; the fifth digit is capacity (1 = 9,200 BTU Cub, 3 = 13,500 BTU, 4 = 15,000 BTU); a 2 in the third position (37223, 37224, 47221) adds the built-in condensate pump; 37xxx is the current R32 generation and 47xxx the R410A generation; the three-digit suffix encodes shroud color and options (-076 and -079 are the common white and black codes). Confirm color with us before ordering, or match the number on your existing unit's data plate.

⚠️ Before You Order

Rooftop unit only — a ceiling assembly and thermostat are required and sold separately (an existing Coleman-Mach ceiling assembly generally carries over). Fits the standard 14" x 14" roof opening; roof gasket pre-installed. Confirm your electrical service can carry the unit.
