Efficient room A/C info request [RE-wrenches]

Hi y'All
The IDAC two stage swamp cooler provides better comfort than single 
stage swamp cooler
We have a evaporative condensor split systems operating around here that 
are SEER 22
The company is no longer in business but custom units can be fabricated 
by our evaporative precooler manufacturer.
Ground source heat pumps also have SEER's in the 22 range and do heating 
as well as cooling. They are not dependent on dry air like the other two 
designs.

Contact me off line for more information  deant at dcn.org  530 867-2392
