What was the 1st year A/C systems actually worked
 

I was wondering if you guys know in what model did the A/C system in the 911 actually start to work? Don't even bother in replying if you live in Wyoming or some other state where your summers are a joke.

I live in Arizona where the temps regularly hit above 110 in the summer, so you southwestern states go ahead and chime in.

Thanks,

993 is what I'd say.

I'd also say 993 (1995).

Demanding but perhaps true..

I am however rather pleased with the A/C in my ´85 Carrera.

996 is what I'd say
none air cooled car has a great A/C

So the A/Cs in the 964s stunk as well?

I wish that the 87 - 89 carrerar's had good A/C, my SCs A/C stinks and I even have fans on the condensor, updated rotary compressor, and a procooler, all a waste of money in my opinion!!!!!!!

Some say the 964 had the modern ac

The vent addition was in '86 so you could probably add that year...but they still left much to be desired.

I dunno, maybe 2006?

I sold my mid-year S and bought a '90 only so I could have air in Atlanta. It works great.

I owned 2 993s and neither of them had really good AC. On hot days if the car had been sitting in the sun the AC could not cool the car to my hot blooded satisfaction. GM's AC works well and the AC in my BMW 3 series gets really cold (that large center vent is magnificient engineering).
My 83 SC AC is a joke, the vents couldn't be any smaller, what were they thinking?

110 ? I'd wait till I got the chance to test the 997's I think even the 996's were marginal for that sort of heat. Try and find a light interior. The 993's and marginally better than the 964's the 964's marginally better than the 911's.

I don't know about 110 degrees but in 93 degree temps during an L.A. trip last summer, my 87 A/C was nice and cool. The P.O had replaced the compressor (nippodenso) about 4 years ago.

Only trouble now is that since last year the last critical bits of freon has leaked out and I now need a recharge.

Question please:
Is a nippodenso condensor a typical replacement for the a stock compressor? Or is it a POS? Seemed to work fine until the leak out.

Rod,

See the following link, basically I added a fan on the deck condenser and an additional condenser w/fan behind the rear wheel, charged with R-12 and am good to go. Not blowing ice cubes but close.

I can show you what I've got if you are interested.

Re: What was the 1st year A/C systems actually worked
 

Still waiting for PORSCHE to make a car with a decent A/C that is not a SUV.

I'm in Tucson as well and since I bought my '86 coupe last February this
is my first experience with 911 AC in the summer. A week or so ago when it hit 107 it did marginally OK until I got stuck in traffic. Then the
AC was still not bad but the oil temp started rising. When the needle
hit the second white line on the gauge I shut it off not wanting to risk
getting closer to the red. (Anybody know what temps those lines
correspond to?) Even after shutting down the AC the temp stayed at the
second white line & didn't drop back down until I started moving again.

As far as I can tell the system is totally stock so I'm thinking with a
few upgrades, like a procooler maybe, it could be made to actually work
reasonably well. That might need to include some oil cooling upgrades.

Barrpete,

Does your car have a fan on the oil cooler, I think the fan was added in 1987 though you do have the better oil cooler, if not it would be a good idea to add one.

As for the gauge marks,
- first lower white block...60 degC ( 140 degF)
- next white line up.........90 degC ( 194 degF)
- next white line up........120 degC( 248 degF)
-bottom of next-up red block...150 degC (302 degF)
if you look at the gauge face at at angle you'll see the celsius numbers next to the lines

what a bunch of poppycock. I know damm well that if my 964 AC actually worked it would kick @ss.

964 and 993 have the same HVAC system.


In '86, it became marginally usefull. Then in '90 it became usefull. The 996 and newer are a no excuses set-up.

My '79 blows colder than my wife's '05 Denali... and that's down here in San Antonio. I rarely have to turn it to the highest setting, and it usually stays at the lowest.

I have a sanden style compressor, fan on the rear deck condenser, additional center vent and a huge under-belly condenser. It works!
