    Hard to tell without a closup of the fittings, but it looks like an old Coleman condenser with precharged lines.

    My personal favorite were the precharged lines that came with bending springs factory installed on about 1.5' of each end of the suction lines.
    If more government is the answer, then it's a really stupid question.

    at least they followed mfg instruction an d sloped the lines and didn't stand them vertical

    yea they could have made it look a tad better (not by much though)
    Changed out 2 condensers using that system last summer. I believe it was a 3/8" liquid line bushed down to 5/16 for the last 15 feet going into flat coils.
    Homeowner didn't want to change the linesets or Evaps so we just dropped in some 13 seer dry charge units.
    Worked pretty well actually.

    If this did have the precharged lineset, couldn't the installer have just moved the condenser over a little more? Probably have to lay down another pad, but wouldn't have the extra 4' of lineset

    Coleman mobile home condensers used the aero quip fitting quite often. Not sure if they still use them. The drown side to using them is they didn't have service valves to pump system down if you needed to. Also leaks may occur as the rubber o-rings didn't seal all the time.

    It was always my understanding that the o-ring on an Aero-quip fitting was only for when the fittings were being joined. ONce they bottomed out you had a metal - metal seal. The only leaks I ever had with them was when the o-ring would get into that sealling surface. There are several still out there that have no o-ring and still aren't leaking.

    [QUOTE=hurtinhvac;15078761]So was there a flared/compression type fitting that held the charge until you tightened the joint?

    Nope... a brass diaphragm held the charge in until the connection was made. Once the fittings were tightened up, four triangle shaped blades in the male fitting would pierce the diaphragm. O rings made the seal like a SharkBite fitting. Precharged line sets are still used today. Saw one last week on a new remote ice machine.

    I remember cutting out many of those fittings and hard-piping directly to the unit. Those fittings seemed to always leak. That's why I distrust mechanical fittings to this day. Although I believe mechanical fitting have improved.

    That's extra, for when someone steels the condenser. It's good for about 5 or 6 replacements.

    Goof.

    My first few weeks I was in the shop when a senior tech came up with a sign that was taped to a coil or something. It said "use frist." He asked another tech what frist was and I stopped what I was doing and listened in thinking I might learn something about a lineset flush, filter drier or something...

    Turns out he was just making fun of the fact that someone misspelled "first."

    Guess I'm still not altogether immune to pipe strectcher jokes...
