Coleman Mach Everest VS-18 Mach-C 18,000 BTU RV Air Conditioner - Black

The Coleman-Mach Everest VS-18 Mach-C 18,000 BTU RV Air Conditioner is a high-output rooftop cooling system built around advanced variable-speed inverter technology. Instead of repeatedly cycling the compressor on and off at full power like a traditional fixed-speed RV air conditioner, the Everest VS-18 continuously adjusts compressor and blower speed to match the cooling demand inside the RV.

The result is quieter operation, more consistent interior temperatures, lower startup demand, improved efficiency, and better humidity control while still delivering up to 18,000 BTU of cooling capacity for larger RVs and demanding summer conditions.

Manufacturer: Coleman-Mach
Series: Everest VS-18 Mach-C
Cooling Capacity: 18,000 BTU
Voltage: 115V AC
Cooling Technology: Variable-Speed Inverter Compressor
Refrigerant: R32
Airflow: 270 CFM
Application: Ducted or Non-Ducted RV Air Conditioning Systems

Available Models

• 2111-00471 — White

• 2111-00481 — Black

The white and black versions use the same Everest VS-18 cooling platform, with the exterior shroud color being the primary difference.

Variable-Speed Inverter Technology

Traditional RV air conditioners generally operate at full compressor capacity until the thermostat is satisfied, then shut off and restart when additional cooling is required.

The Everest VS-18 continuously varies its compressor and blower speed to better match actual cooling demand. This helps provide:

• More consistent cabin temperatures

• Quieter operation

• Reduced compressor cycling

• Lower startup current

• Improved energy efficiency

• Better humidity removal

• Smoother temperature control

18,000 BTU Cooling Capacity

With 18,000 BTU of cooling capacity, the Everest VS-18 provides substantially more cooling output than conventional 13,500 or 15,000 BTU RV rooftop air conditioners.

Its higher capacity makes it especially well suited for:

• Larger travel trailers

• Fifth wheels

• Motorhomes

• Toy haulers

• RVs frequently used in hot climates

• Applications where faster cabin cool-down is important

Ducted or Non-Ducted Installation

The Coleman-Mach Everest VS-18 can be used with both ducted and non-ducted RV air conditioning systems.

It installs through a standard approximately 14" x 14" RV roof opening, making it suitable for many new installations and rooftop air-conditioner replacements.

R32 Refrigerant

The Everest VS-18 uses R32 refrigerant, a newer refrigerant with a lower Global Warming Potential than refrigerants traditionally used in many RV air-conditioning systems.

High-Volume Airflow

The Everest VS-18 delivers approximately 270 CFM of conditioned airflow, helping cool the RV quickly and distribute conditioned air throughout the interior. When paired with the appropriate Coleman-Mach Everest ceiling assembly, the system can provide broad 360-degree air distribution.

Built for RV Use

The Everest VS-18 incorporates several design features intended for demanding rooftop RV installations, including:

• Heavy-duty steel base construction

• Hydrophobic-coated evaporator coils

• Increased protection around the coil and shroud

• Improved moisture drainage

• Reduced susceptibility to evaporator freeze-up

• Protection from road debris, weather, and hail

Approximate Specifications

• Cooling Capacity: 18,000 BTU

• Voltage: 115V AC

• Airflow: 270 CFM

• Weight: Approximately 68 lbs.

• Length: Approximately 32.5"

• Width: Approximately 25.1"

• Height: Approximately 12.6"

• Roof Opening: Approximately 14" x 14"

Important Installation Information

The rooftop air conditioner is not necessarily a complete installation kit by itself.

Depending on the RV and installation type, the following components may be required and sold separately:

• Compatible Coleman-Mach thermostat

• Control kit

• Ceiling assembly

• Ducted or non-ducted interior air-distribution components

Always verify the existing RV air-conditioning configuration and required interior components before ordering.

The Coleman-Mach Everest VS-18 Mach-C combines 18,000 BTU cooling capacity, variable-speed inverter technology, R32 refrigerant, and ducted or non-ducted compatibility for RV owners looking for a more powerful, efficient, and refined rooftop air-conditioning system.
