aircon value

[haul]

@all,

i had a quite nice meeting yesterday and within our usual discussions I had been asked, how a factory aircon for the early cars would be valued. One of my pals wants to get rid of his installation, another pal is interested, but how to value all the hardware, condensers, blowers etc.??

As I am not an expert on aircons, I thought, well, I am sure someone knows anything about this topic and might chime in…

please, educate me…

with very best regards from Bavaria

The cost of the box to store it in. Zero value.

In high temperature/high humidity areas, air conditioning is mandatory and adds thousands in value to early 911s. There are several component enhancments available to make it (slightly) more effective.

Where you are, it's unlikely to be a plus.

A lot depends upon year. A/C only available for first time on USA '67's. Original was Porscheair (Delanair) system that used Tecumseh compressor. Was dealer installed. That may have carried over to '68. My experience limited to 912. Tecumseh is generally frowned upon in 912 world because robbed one or two horsepower. Required a two belt engine pulley. On a 912 they supplied a bolt on second pulley for the second belt. In 1968 often confused with the two belt emissions control pulley. Don't know 911. Upgraded to York compressor which had same net engine drag on HP. I think in '69 they changed over to a Porsche installed under dash vents and the Porscheair label was dropped. I think York compressor was continued.

I guess the question to ask is whether the buyer is looking for efficiency or period correctness. I'd guess the HP loss on a 911 not as critical so compressor not so critical. Also have to decide if going to use R12 or R134 refrigerant. Hoses different. Porscheair components harder and harder to find. The under dash vent system was re designated and designed as BEHR. Trouble with either was the plastic vents directing the air were very flimsy and mostly broke. I have some reservations about denigrating the Tecumseh compressor as it was used in VW's with great success and a series of American cars. Most good A/C rebuilders still rebuild them.

That's why year is important. Correctness will be the requirement for the price. 911 engine mounting pieces often forgotten. My understanding is they are flimsy. Problem avoided in 912 application since the compressor is mounted very well on engine cross bar.

Ed Mayo might be able to help. I think he used to install at dealer. Big complaint is that most dealers had the coffee boy install the things and they made some really large hole in the body.

I have the factory installed Behr unit in my 72’ T. Years ago, I wanted to take it out and toss it to the wind. Glad I didn’t. It’s still installed in the car & works too. I’m in the Southwest so it’s a bonus for me to have AC. ALSO, was told that the plumbing holes would be a hassle to cover up & even more of a hassle to plumb into a non AC donor car.

@all

thank you for teaching me the aircon lesson…
Thus I could check and find more about
condensors, compressors, under dash blowers etc usw…

Lesson learned…again thank you all for the answers

I've got about 2/3 of a Coolaire system I removed from the car in 1978 and is still sitting on some basement shelving. Just like the holes left in the body by a slapdash dealer installation, it won't go away.

[doigthom]

If I recall Coolaire not the chosen system by Porsche. Went from Delanair/Porscheair to Behr. I think Behr was first Factory install. Coolaire installed by dealers but had a big plastic bump cover in place of smugglers box door. Not much historical value. Big problem for those who want concours is the red hose.

Either VWofA or Behr by 72
