R 410-A is here to stay. R410-A is the refrigerant that is replacing R 22 due to the federal ban and ozone depleting qualities. As R 22 is being phased out, it is getting more and more expensive, and it will only get worse. New units today are not even available with R 22 in them from the factory. Be sure to take this into consideration when deciding to repair or replace an old unit with R 22 in it. The current price for a pound of R 410-A is half that of R 22. For this reason it makes financial sense to replace an older R 22 unit when a leak develops or a major repair is needed, rather than repair it.
