[928uk] A/C

[Ben Hodges]

Vac was also critical to remove air from system before charging - air not
good as it carries moisture.

Also, as you’ve prob seen getting r134 is not easy without all the F-gas
stuff. The compatible stuff on eBay can be flammable so be careful of that.

I would get gauges and buy/borrow an vac pump (an electric a/c one - not a
hand one :-)) and do some initial diagnosis. System should hold
Vacuum indefinitely so you can chase down obvious leaks yourself first.

Cheers
Ben
