In 1988 when I quit my job as the national service manager for a major HVAC equipment company to become an editor for an HVACR trade magazine, I was asked by then-ACCA Director Jim Norris to look into the question of whether CFCs (particularly R11 and R12) were damaging our planet by destroying the earth’s protective ozone layer.
So, under the auspices of the magazine, I attended all the environmental conferences to find out everything that I could. And what I came to realize was that CFCs do in fact damage the ozone layer. So, I wrote an award-winning series of articles calling for their phase-out.
