Coleman 38204-0640 Mach 15 DQ 15000 BTU Ducted RV Air Conditioner Textured White

The Coleman Mach 15 DQ (38204-0640) is a 15,000 BTU ducted rooftop air conditioner engineered for RV applications demanding maximum cooling output. As the flagship of the Coleman Mach series, this unit delivers the highest cooling capacity available in a rooftop RV air conditioner, making it an ideal replacement or upgrade for larger coaches and fifth wheels.

The DQ (Ducted Quiet) designation means this unit is purpose-built for ducted ceiling distribution systems, channeling conditioned air evenly throughout the RV via the existing duct network. Its powerful 1/3 horsepower fan motor — the largest used in any RV air conditioner — drives airflow at an impressive 320 CFM, ensuring consistent temperature distribution across every zone.
