    Did you know...
    The man that invented Freon also invented leaded gasoline?

    from: http://en.wikipedia.org/wiki/Thomas_Midgley

    Thomas Midgley, Jr. (May 18, 1889 - November 2, 1944), was a American mechanical engineer turned chemist. He developed both the tetra-ethyl lead additive to gasoline and chloro-fluorocarbons (CFCs). While lauded at the time for his discoveries today his legacy is seen as far more mixed. One historian remarked that Midgley "had more impact on the atmosphere than any other single organism in earth history."

    While working for General Motors he discovered that leaded-gasoline prevented internal combustion engines from "knocking". The difficulty is that this resulted in huge amounts of lead being added to the atmosphere causing health problems around the world. Workers producing the additive were even more greatly affected. In 1924 Midgley took a prolonged vacation from working to cure himself of lead poisoning — A fact he deliberately kept secret, holding a press conference to demonstrate the "safety" of contact with the substance

    CFCs were introduced to make refrigerators safer by synthesizing chloro-fluorocarbon (CFC) compounds (also called "Freons") and substituting them for the variously poisonous or explosive substances previously used.

    (He's still my hero.)

    See, I knew they were safe!

    If he'd have lived, he probably would have invented 410A, the unleaded freon.

    Thanks for the post.
    I was beginning to wonder if ANYBODY reads these things.
    When first I posted, I thought I'd picked a slow news day.
    I see you have started several recent threads.
    Keep up the good work.

    I miss the good old days, too.
    Life was simpler then.

    Hmm R-22, R-410A and Leaded gasoline

    The person who was informed that there is an "expiration" or phase-out for R-410A (or "PURON") was misinformed. R-22 is definately going away. There is no legal basis or consideration by U.S. regulators to phase-out R-410A.

    The comparison of leaded gasoline is interesting. Would you have bought a car that ran on leaded gasoline if someone told you that leaded gas was being phased out in 10 years?

    If not, then why install an R-22 air conditioner? We know it's going away, and that the 2015 EPA reduction in R-22 production will significantly reduce supply. These systems are supposed to last 10-15 years.

    Yes, I did, and probably would again.
    I bought 3/4 ton trucks when unleaded was first introduced.
    1/2 ton required leaded gas, at a HIGHER price.
    Leaving out the lead made gasoline cost more. (Go figure.)

    I don't still have any of them.
    10 years is a long time to keep a car around.

    Gasoline is designed to be used up.
    Refrigerant is a component, designed to stay in the system.
    If an air conditioner needed recharged once a week, then the comparison would be more valid.

    The reason r-22 is still being installed is the very REAL and SIGNIFICANT increase in PRICE of R-410A equipment.

    R-22 will take a back seat ONLY when it costs more.
    Sad but true...
