Who We Are
That man to the right in the white shirt on the roof waving,.. That’s Glenn McKinny. Glenn McKinny was a Chief Engineer in the U.S. Navy. Air Conditioning, Heating, and Refrigeration has been our family business since Glenn McKinny’s honorable discharge in 1966. Starting out in San Diego, California, our family purchased Bailey’s Refrigeration from Mr. Bailey, and ran that operation on Broadway in El Cajon for a while before selling it back to him, after opening Glenco Refrigeration.
