    I know that the a good service tech would have 3/8", 7/16", 1/2", and 9/16" wrenches in his bag... Would anybody add to that... Does anybody use a regular combination wrench to remove carrier service valve (king valves) stem covers?... Does anybody use a wrench to remove the caps on pump down valves?.... I use nutdrivers for 11/32", 3/8", and 7/16" for blower wheel mounts, and was considering using a 1/2" for compressor mounts, does anybody else do that?... OR do people have a small and a large adjustable wrench do it all? Or the least best option, a pair of channellocks?

    I use a 1/4" drive socket set. Works most of the time.
    If the superheat ain't right it ain't charged right.

    Wrenches for most work, and 4 sizes of adjustable wrenches.
    Plus sockets for compressor mounts.

    I like having flare-nut wrenches on me....great for preventing busted knuckles.
    If everything was always done "by the book"....the book would never change.

    I agree with Beenthere. I have a standard 7pc nut driver set, use 1/4, 5/16, and 3/8 the most. Adjustable wrench to take covers off King valves, and I also carry a Craftsmen set of wrenches. Open on one end and ratcheting boxed on other end. That ratcheting box end comes in handy a lot to get to screw heads that don't even have enough clearance for a socket in fromt of it. I don't use them often but when I do I'm REALLY glad I got them.

    Always give your best effort, be honest, and let the chips fall where they may.

    My wife gave up on asking what tool I was buying now, hence the user name (Binford)
    I also carry a pair of needle nose vise grip pliers.

    Offset boxed end 3/8"x7/16" and 1/2"x9/16" are very valuable.

    I like to keep a 4' Rigid steel pipe wrench in my pocket just in case.
