Can anyone recommend a company to service/repair the air con on a 993 near to St.Albans. Have had system topped up twice now but still no cold air

The obvious Porsche specialists near you are JAZ, JZM and RPM Technik. I've used both of the latter, both are good but RPM are cheaper in my experience. JAZ have a good reputation too but never used them and they are in St Albans,

Thanks for that. Has anyone used the replacement air conditioning unit from Classic Retrofit?

JAZ are very good. 993 a/c is a world of pain and you basically have to replace everything and it still will not work like a modern car. JAZ top mine up every year (£75) and it soldiers on having done pump and various other bits bar evaporator which is under the tank and £1500 job to fix. Could be CCU unit, could be any one of the fans, mixer flaps or relays.

Alpineair are supposed to be good, only at Hanger Lane and have done 993 evaporators see http://www.alpinair.co.uk/ 911UK forum has many useful threads on it.

Tore's site is excellent: https://www.bergvillfx.com/categories/964993-hvac-...

Have you checked the vacuum hose on the inside of the engine bay (near side)?

I had no cold air, had the Kwikfit free top up but it still blew ambient so they didn’t charge me (they guaranteed an improvement or no charge).

Couple of weeks later, noticed a loose pipe on a manifold in that area of the engine and once reconnected, it blew cold again. It must have been part of the control system I’d worked loose when doing some engine work a while ago, might be worth checking before digging into the more expensive options!

Mine stopped working temporarily as result of a relay. Contrary to what others say, mine was very powerful and effective the equal of any modern car I’ve had. 1996 C4.

I'd agree that they work fine when they're in good condition. Unfortunately by now most will need a complete new set of parts to work properly, including condenser, evaporator and compressor.

You could also consider Ray Northway over in Reading for the work.

I haven't used the Classic Retrofit system but I saw the development system on JH's car a few years ago and was impressed. I also have one of his 3.2 fuse boards on my car and really like the quality and the engineering that he produces.

When I eventually entirely re-do the AC in my car, it'll be one of his systems that I fit.

This ^^^^.

When mine was working (it needs only a regass I hope at the mo as it’s blowing warm), it would blow cold air and keep me comfortably cool in 42degree heat on a sun baked jolly in central Spain in height of summer.

I use Jaz for servicing and they recommended Alpinair on Hanger Lane. Jaz had taken a look but thought it would be better going to Alpinair. Long story short but they have to remove so much to get to the condenser and dryers etc I had them replace anything that looked suspect. Wasn’t cheap but did a good job.

I used this as an instruction guide to go through the aircon on my 964. If you've time and the spanners it's wuite rewarding.

Air conditioning now all sorted thanks to new condenser supplied and fitted by Jaz during major service, really good guys. After17 years and 125,000 miles of ownership car now driving better than ever thanks to Jaz service andCenter Gravity suspension overhaul.
However think now might be time to change. Fancy Ferrari 360, has anyone here made that move?

Didn't Jackal get a 360 soon after selling the 993?

But you are mad. Or rich. Or both
