Saving Cooling and Heating Energy

About

Passion. Experience. Diligence.

History

GreenFan was created to advance the basic design of a cooling only adaptable time delay patented by John Walsh in April of 2010.  Collaboratively, Robert Mowris and John Walsh added the heating functionality in 2011.   GreenFan was incorporated by Walsh and Mowris in October of 2012. Since inception, GreenFan has sold over 86,000 Efficient Fan Controllers® into the California and Montana utility markets.  Each unit represents a home in which the residents are saving heating and cooling energy and lowering their carbon footprints.
