Coleman-Mach: The Original RV Air Conditioning Brand

When it comes to keeping RVs, boats, and specialty vehicles cool and comfortable, few names carry more authority than Coleman-Mach, distributed through Coast Distribution Systems. Coleman-Mach air conditioning systems have defined the standard for recreational vehicle climate control for more than half a century, and their reputation is built on a foundation of genuine engineering innovation.

The story begins in the summer of 1966, when Sheldon Coleman took a motorhome trip and came back with one clear directive for his engineering team: design an air conditioner for the coach. The result was the PolarPal — the first RV air conditioner ever produced, debuted in 1967. That pioneering spirit has never faded. Today, Coleman-Mach air conditioners are produced at their facility in Wichita, Kansas, and the brand has surpassed 9 million units built — a milestone that underscores the level of trust RV owners, OEM manufacturers, and dealers have placed in the product line for decades.

Now operating as part of the Airxcel family of brands, Coleman-Mach has grown well beyond the original single rooftop unit. The full Coleman-Mach lineup includes rooftop air conditioners, heat pumps, ceiling assemblies, thermostats and zone control accessories, conversion kits, and replacement air filters — everything needed to install, upgrade, or maintain a complete RV climate control system.

A System Built for Every RV

One of the defining strengths of the Coleman-Mach lineup is its breadth of compatibility. Units can be installed on Class A, B, and C motorhomes, fifth wheels, towable trailers, pop-up campers, truck campers, and even marine and off-road specialty vehicles. Models are available in multiple rooftop profiles — standard, medium, low, and ultra-low — helping RVers minimize wind drag and maintain a clean exterior silhouette while still getting powerful climate control inside.

BTU output options span a wide range to suit everything from compact trailers to large Class A coaches, and both ducted and non-ducted ceiling assembly configurations are supported. Heat pump models add two-season versatility, allowing the same rooftop unit to handle cooling in summer and supplemental heating when temperatures drop.

Smart Controls and Accessories

Modern Coleman-Mach systems pair seamlessly with the brand's own digital thermostats and zone control accessories, giving occupants precise temperature management throughout the RV. From simple wall-mount thermostats to multi-zone control systems, the accessory lineup is engineered specifically to work with Coleman-Mach hardware — eliminating the guesswork of mixing and matching components from different manufacturers. Proper filtration is equally important, and Coleman-Mach air filters are designed to protect the system's evaporator coils and maintain healthy airflow, extending the life of the AC unit and preserving interior air quality.

For RV enthusiasts, fleet managers, and marine operators who demand dependable, American-made climate control with a proven track record, Coleman-Mach — distributed by Coast Distribution Systems — remains a benchmark brand in the industry.
