Experience the future of RV climate control with the Coleman-Mach Everest VS-18 Mach-C Variable Speed Air Conditioner, the next generation of premium rooftop cooling engineered for superior comfort, energy efficiency, and quiet operation. Delivering an impressive 18,000 BTU cooling capacity, the Everest VS-18 Mach-C (Model 2111-00471) utilizes advanced variable-speed inverter technology and environmentally friendly R32 refrigerant to provide faster cooling, lower energy consumption, and more precise temperature control than conventional single-speed RV air conditioners.
Unlike traditional rooftop air conditioners that repeatedly cycle on and off at full capacity, the Everest VS-18 continuously monitors interior conditions and automatically adjusts both compressor and blower motor speeds in real time. This intelligent operation maintains a consistent cabin temperature while reducing compressor cycling, minimizing startup current, lowering power consumption, and significantly decreasing operating noise.
Whether connected to shore power, operating from a generator, or managing limited campground electrical service, the Everest VS-18 intelligently adapts its cooling output to match the demand. The result is improved comfort, reduced energy usage, better humidity removal, and quieter operation throughout your RV.
Designed to fit standard 14-inch x 14-inch rooftop openings, the Everest VS-18 features a compact 800 square-inch rooftop footprint and a low-profile housing that maximizes valuable roof space for solar panels, antennas, satellite systems, and other accessories.
Built specifically for the demands of RV travel, the Everest VS-18 incorporates a durable powder-coated steel base pan, hydrophobic-coated evaporator coils, and increased shroud-to-coil spacing for exceptional durability, faster condensate removal, improved freeze resistance, and enhanced protection against road debris, hail, and harsh outdoor environments.
Compatible with both ducted and non-ducted RV air distribution systems, the Everest VS-18 delivers powerful, even cooling throughout your coach when paired with the Coleman-Mach 360° Airflow Ceiling Assembly, helping eliminate hot spots while maintaining consistent interior comfort.
Whether you're a full-time RVer, weekend traveler, or seasonal camper, the Coleman-Mach Everest VS-18 delivers premium cooling performance backed by one of the most trusted names in RV HVAC.
Features & Benefits
Variable-Speed Inverter Technology
Unlike conventional fixed-speed rooftop air conditioners, the Everest VS-18 continuously adjusts compressor and blower speed to precisely match cooling demand, providing greater efficiency, quieter operation, and more consistent cabin temperatures.
Powerful 18,000 BTU Cooling Capacity
High-capacity cooling provides rapid temperature reduction for larger RVs while maintaining comfortable interior temperatures even during extreme summer conditions.
Environmentally Friendly R32 Refrigerant
Utilizes next-generation R32 refrigerant, offering improved energy efficiency, greater cooling performance, and a lower Global Warming Potential (GWP) compared to previous refrigerants.
Lower Power Consumption
Variable-speed operation minimizes electrical demand by eliminating repeated high-amperage compressor starts and reducing unnecessary energy usage once the desired temperature has been reached.
Quiet Operation
The intelligent control system continuously modulates compressor and fan speeds, dramatically reducing operating noise compared to conventional rooftop air conditioners.
Intelligent Climate Control
Advanced onboard electronics continuously monitor interior conditions and automatically adjust cooling capacity to maintain stable temperatures without excessive cycling.
High Airflow Performance
Produces 270 CFM (Cubic Feet Per Minute) of airflow for faster cabin cool-down and more uniform air distribution throughout the RV.
360° Airflow Compatibility
Designed for use with the Coleman-Mach 360° Airflow Ceiling Assembly, delivering even airflow throughout the coach while minimizing hot and cold spots.
Compact Rooftop Footprint
The compact 800 square-inch footprint occupies less roof space than many competing rooftop air conditioners while maintaining full cooling capacity.
Low-Profile Design
With an overall height of approximately 12.13 inches, the Everest VS-18 reduces rooftop profile while maintaining outstanding cooling performance.
Powder-Coated Steel Base Pan
Heavy-duty powder-coated steel construction provides outstanding corrosion resistance and long-term structural durability.
Hydrophobic-Coated Evaporator Coils
Specialized coil coating promotes rapid moisture drainage, improves heat transfer efficiency, and helps reduce evaporator freeze-up during high-humidity operation.
Enhanced Coil Protection
Increased shroud-to-coil spacing provides additional protection against hail, tree debris, and road hazards encountered during travel.
Universal Installation
Designed for both ducted and non-ducted RV HVAC systems using standard 14" x 14" roof openings.
