The Environmental Protection Agency has tried to reduce use of this gas,
HCFC-22, which depletes the ozone layer and contributes to global warming,
by imposing strict quotas on its production.
But what followed at Mr. Spector'a home circumvented all the agency's
rules and good intentions: Instead of finding and repairing the hole in
his aging unit, a complicated task, a serviceman pumped in more coolant,
which leaked out by the next day. When Mr. Spector called around for
another solution, a salesman offered to swap in a new condenser unit, but
one that still used HCFC-22 - meaning one more American home would
continue relying on an environmentally damaging coolant for years.
Oh, and the article also claimed:
In the end, Mr. Spector bought an entirely new system, running on
R-410A, the gas that has been used in almost all new machines in the
United States since 2010 and is far more energy-efficient and better
for the ozone layer.
Anyone know if R-410A is really "more energy-efficient"?
