Auto Air conditioning specialist recommendation?

Hi,

I'm looking for a recommendation for an auto air conditioning specialist (Not the Land Rover dealer, I know where that is and they are not specialist)

The reason for this request is that I have replaced the condenser myself (yes I did get it drained of gas first). I have 2 reasons for wanting specialist resource:
1. I fitted new o-rings from a packet in Migros because that was all I could find. The are the right size but unsure regarding specific material suitability
2. I had to bend a pipe manifold on the replacement condenser to match the old one/make fit and there's a change that area will want metal brazing.

Thanks for your help

Andy

If the O-rings aren't suitable for A/C use then they'll stop being o-rings in very short order. Who knows if the Migros o-rings are Viton, NBR, PNBR, or cross linked monkey snot? I don't.

Good luck finding an automotive A/C shop that would braze a crack. You might have better luck taking the condenser to a regular HVAC shop. Few garages even rebuild brake calipers nowadays - they'll have a smoke axe for getting bearings off and loosening rusted fasteners, and possibly a MIG for patching exhausts, but paying one for Al brazing/TIG welding a cracked condensor pipe will probably cost as much as a new evaporator.

Re: Auto Air conditioning specialist recommendation?

Hi,

Thanks JagWaugh you have actually been able to set my mind at rest.

First there are no visible cracks. Bending an aluminium manifold was the last thing in the world I wanted to do but there was no choice. I have since been advised by the parts supplier that other customers had reported the pipe difference and bent them in the same way without issue.

Second, regard o-ring rubber compound I have fished out the Migro packet, noted the contents were made in Germany and looked up the part number/manufacturer. The o-rings are NBR and have high suitability for R134a.

With this in mind I am off for a refill tomorrow morning.

Thanks,

Andy

They'll be able to tell if the pipe was cracked as soon as they put a vacuum on the system. Tell them that you might have cracked a pipe up front, and leave covers and such off when you bring the vehicle in. They can add a UV dye (to check for leaks) to the oil on charging and if they know that there might be a crack at the condenser then they'll start looking there.

Re: Auto Air conditioning specialist recommendation?

Quick update,

I found these guys just over the border in Germany who do a nitrogen gas pressure test and are open all day on a Saturday. FYI this is a much more reliable method of checking for leaks by comparison with a standard vacuum check because the system is pressurised in excess of operating pressure.

http://www.autofullservice-danner.de/

Total cost was about EUR150 and the pressure test was EUR60.

The guy shook his head when I said I had changed the condenser myself, so it was a great feeling to be told it didn't leak! Plus I now have glorious cold air in my car!
