    The thread title just BEGS for a smart comment.

    Okay. What kind of "trane unit" is it?

    Serial number?

    Who would be doing the work for you?

    Such as ... If you dont know how big your unit is ....do you need a yard stick or a micrometer ???

    Or.... maybe a trip to the optician is in order ???

    Or ...ask your wife/girlfriend/significant other (gotta be politically correct ya know) ??

    Missing some digits. It's a 3 ton with the old quick connects so likely a low SEER from the 70s. What is R22a?
