You might wish that summer could go on and on - until it comes time
to recharge your air conditioning system. The cost of the common refrigerant
R-22 (also known as Freon), widely used in residential air conditioning systems,
has already increased by more than 400 percent in the past 18 months and is
expected to go even higher, making air conditioning repairs more costly for
many.
R-22 has been the refrigerant of choice for residential heat pump and air
conditioning systems for more than four decades, but it has been identified as
having a negative environmental impact, including contributing to ozone
depletion. Under EPA regulations, R-22 is being phased out, with production
totally prohibited after 2020.
This has added new considerations for homeowners who are considering whether
to repair or replace an air conditioning unit. For instance, some refrigerant
manufacturers have begun selling cheaper alternatives to R-22, often referred to
as "drop-in" replacement refrigerants. But alternatives are cheaper only in the
short run.
Recharging older air
conditioners with these alternative refrigerants may actually damage the system
and void your manufacturer's warranty. As a result,
technicians will follow the manufacturer's recommendations and use only R-22 when
they recharge R-22 systems.
Recycled R-22 is expected to be
available to repair existing systems after production ceases in 2020, but as the
supply of new R-22 refrigerant continues to be reduced, costs of both new and
recycled R-22 refrigerant will increase significantly.
All new air conditioning systems now use a more environmentally friendly
refrigerant, R410A.-These newer systems offer many benefits, including greater
energy efficiency, longer warranty periods and quieter operation, and may prove
to be the wiser investment when homeowners are faced with repairing an older
system that uses R-22 refrigerant.
Replacing an R-22 air conditioning system really does depend on the individual family, their
home, their lifestyle and their budget. The service technician should be trained to help the consumer make the most informed decision.
