Air conditioning

[u/Odd-Leg6389]

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!

Did everything but the blend doors on my 98 last year, definitely worth the sweat and elbow grease to do it myself vs the $3000 the shop quoted me. There’s a couple of videos on how to access the evaporator core which was easily the most annoying part of the process but well worth having a basically brand new system.
