The Climax VS12

The Worlds Most Efficient Portable Air Conditioner Features:


12,000 BTU Rating

This is a "real" rating of the unit at AHRI official test conditions, not a simple "change of enthalpy" rating like what is used by most portable air conditioner manufacturers, a rating method that fails to consider infiltration air. At 95 F outdoor temperature and 75 F indoor temperature, the Climax VS12 delivers nearly twice the net cooling of a standard 12,000 BTU rated portable air conditioner.

Saves 50% Electricity

Climax VS12 uses 50% less energy compared to normal portable air conditioners of the same rated capacity. Actually the VS12 can save up to 72% under certain hot weather conditions.


No Drain Line Needed

Self-evaporative feature vaporizes accumulated condensate and blows it out the exhaust hose avoiding the need for a drain line or reservoir. This prevents the need for running a drain line or emptying a reservoir.


DC Inverter Compressor

High SEER variable speed DC compressor saves power, has a much longer life, runs more quietly,  and starts softly to avoid voltage spikes or brownouts.

This is the same type compressor used in the worlds highest SEER mini-splits, and has a much higher EER, SEER, and COP than standard compressors used in portable air conditioners. Learn about portable AC DC Inverter compressor


Dual Hose Design
