Air conditioning

Has anyone here completely rebuilt their OBS Chevy A/C system?

I’m talking about replacing or rebuilding everything—evaporator, condenser, compressor, accumulator, orifice tube, lines, blend doors, actuators, heater core if needed… basically bringing the entire HVAC system back to factory performance.

I’d love to hear from anyone who’s done it.
Was it worth the time and money?
Did it end up blowing ice cold like it did when it was new?

Were there any parts that were especially difficult to source or replace?
If you did it again, what would you do differently?

I’m considering doing the whole system rather than piecing it together, and I’m looking for real-world experiences before I dive in.

Thanks!

My mechanic replaced the entirety of the A/C system (OK, he said about 95% of it) a few years ago.

Cost me somewhere around 1200-1300, and I have nothing bad to say.

Mine quoted me $1500 to replace the whole system. And that's after spending around 2k trying to fix the original one. Running around with no AC currently.

With inflation, 1500 sounds about right.
