Aftermarket AC

Just for fun, a thread on aftermarket/dealer add-on AC units. Big in the 50's/60's before Detroit paid attention to AC as somewhat standard. Lots of mfrs. from southern states but not much detail on the web other than installation prices in newspaper ads. $300+ or so.

Mine is installed in my 1960 Cadillac SDV and appears to be 1960 vintage and added by the dealer. The Cad came from SW Ohio and the dealer is still around.

It is a Parkomat 727, one of several variations they made and never detailed in the history of the web. There is no web photo of this version. The others are larger with big round vents. All work the same way. Strap on the compressor, condenser, evaporator and under-dash chrome-plated monster and get cool. Recirculating only in my case. Power and temp controls are separate from the Cad dash. Drain hose goes through a new hole drilled in the pan near the trans hump.

The hoses at the compressor are radiator clamped. Condenser and dash unit are sealed hoses. And mine is converted to R134. A recharge, new charging fittings and clamp tightening brought it right back until I kicked the compressor power loose as it is near my foot tip on the gas pedal. Easy fix following the compressor black power wire.

Show your unit and lets gather some history on these units.
