R-410-A STORY
410A - Keeping You Cool and Protecting the Environment!


Most air-conditioners and heat pumps sold around the world use a refrigerant called
R-22. Emissions of R-22 are considered by some experts to be a significant factor in
depleting the ozone layer that protects animals and people from harmful rays from the
sun.

Families now have the choice to ask for an air-conditioner or heat pump that uses a
more efficient and environmentally friendlier refrigerant called 410A or R-410A when
buying a new system for their home.

Replacing Your Old Air Conditioner or Building a New Home?
You should select a new system that doesn't use ozone-depleting refrigerants.

Why? Because by selecting R-410A you eliminate the possibility that refrigerant leaking
from your system might contribute to the hole in the ozone layer, and you'll also be
investing in a comfort system that will last you for many years to come.

Phase-Out of Ozone Depleting and Chemicals


The United States signed the Montreal Protocol on Substances that Deplete the Ozone
Layer, which is an international agreement to reduce and eventually ban the production
of most ozone depleting chemicals. In order to implement this agreement in the U.S.,
Congress passed the Clean Air Act of 1990. This directed the EPA to implement
regulations to phase out CFCs and HCFCs.
The production of CFCs for air conditioning and refrigeration in the United States was
banned in 1995. CFCs are much more harmful to the environment than HCFCs, but HCFCs
are next in line for elimination. The chart above shows how much and when the United
States must reduce use of ozone depleting HCFCs such as R-22.

The impact on the ozone layer for every HCFC chemical such as R-22 has been estimated
and compared to that of CFC-11. This impact is called its "Ozone Depletion Potential" or
"ODP". For R-22, this number is 0.055 because it is 5-1/2% as ozone depleting as R-11 over
a 100 year period. There are many other ozone-depleting HCFCs, such as "141b" which is
used for insulating refrigerators and houses. Production of HCFC-141b in the U.S. has
already been banned and other HCFCs are scheduled to be phased out.
