Air con retrofit pressure testing

[cRaigAl205]

Hi there,


I'm in the midst of retrofitting a complete air con system to my 205 GTi, I was wondering if you had any suggestions for somewhere to pressure test the individual components- I'd really like the evaporator pressure tested before installing it behind the 30+ year old brittle plastic dashboard etc!

A few garages I've contacted so far can only do the entire system using the fill valve.

Any suggestions welcome!

Many thanks,
Craig
