    If we all simply "get used to things" there would be no need for this forum

    Wrong my friend.We offer tech support to one.Something is only as hard as you make it.I cannot make you to the point to where you accept the fact and relize that it is not a big deal.You must not have worked on 410 systems before.I am not insulting you by the way.

    Re: the 502. Just curious, I worked with very low temperature equipment (freeze drying) many years ago which used 502. Is there a drop-in replacement?

    stop worrying and get a little more training on 410. The change is something that has been underway for years and though there will be bumps along the road it should not be a big deal. From a Techs perspective the manufacturers are the folks who have the hassles. If one of my customers needs a new system I guide them to a 410 system. If they have a fairly new R22 system I don;t have any problem repairing it for them knowing it can give them many more years of service and parts will be available. you can still purchase R-12, 502 and other obsolete refrigerants. They are expensive but available.

    with POE education will be more important especially for installers who don't purge with N2 or pull vacuums. (just about every installer in the florida panhandle) the names and faces have changed but the principles of refrigeration are the same.

    You cant vent it for the same reason you cant vent 134a, the global warming potential. 410a has about 1700 X the global waming potential of carbon dioxide.

And R-22 will still be manufatured but with a 65% decrease in production. even though 410A runs at higher pressures it is still safe for use in homes.
    Thanks Tiger93RSL. Your answer is right on the money! Some of discussion treads seemed to sway from my topic while others spoke about the past and present rather than the future. A few decided to challenge my creditability but for the most part, I'm pleased with this discussion forum.

    For those who need to know my experience, I have been a Verizon HVAC for 25 years with 10 years of residential experience prior to Verizon and I hold a masters degree (MSM) in management.

    Again Tiger93RSL Thank you.

    May be mistaken but believe Carrier produced some R134a residential units for a year or two before they brought out R410a.

    R22 equipment can still be manufactured, it just can't have any R22 in it, basically making it a big part. Don't know if any manufacturer's are going to seek this market, but it is not illegal.

    R410a pressures are not more dangerous then R22 pressures are. By the way, the reaction to the higher pressures of R22 compared to what was being used when R22 was developed was the same; "oh nooooo....we're all gonna die because of the high pressures of R22!". If anything, the higher pressures should make it easier to find those pesky little leaks faster, before they become big dangerous leaks.

    As for "why recover"? R410a is not supposed to be as harmful to the atmosphere as R22, but is still not something we want to be breathing. You don't see signs reading; "Don't pee in the pool, unless you have really weak pee!" do ya?

    Ive installed six 10ton units this summer so far. All came filled with helium instead of R22.
