Air conditioning repairs - need to be a Porsche specialist?

[Suekatg]

Hi all - I have a Gen 2 911 and there are issues with the heating and air con.
The blowers make a squeaking noise when on and I don't think the temperature regulates well.
My local Porsche specialist has quoted £470 to look at the blower noise and £560 to replace both condensors.
I have my other repairs and servicing done at the Porsche specialist, but is there a need for air con to be fixed there or could I go to an air con specialist and likely get this work done cheaper without devaluing the car?
Thoughts?
Thanks
Susan

Plenty of hopeless indys (and a good few OPC's too) when it comes to tracing and fixing A/C issues.
I'd get it to a specialist, as they seem to understand the issues/pitfalls better than companies/individuals who see the issues once in a blue moon.
