AC Compressor - rebuild yourself? #813706 05/22/07 09:18 PM

Getting the Wheeling Fever
Having just been told that my AC system repair will cost $1700 I am considering rebuilding the Reed Valves on the compressor myself - the tech told me those are likley the problem because the clutch looked good to him and the system had freon in it. He said the compressor is not building up enough pressure to circulate the freon.

They tell me a reman compressor cost $900 and a receiver dryer cost $180 - make sense? Comments or thoughts?

individual parts for compressors are not typically available IME

i usually install a used one from a reputable junkyard or "auto recycler" <img src="/forums/images/graemlins/notooth.gif" alt="" /> along with new o-rings at the junctions on the pump, car-part.com is a good way to find one

pressure wash it before you start teardown, and make sure not to get any dirt specks, liquids, etc. in the system

Thanks - I did a quick search and see that I can find a reman compressor for about 350, dryer for 50 - junkyard ones have worked for you, eh?

Any other hints on the whole process would be appreciated! <img src="/forums/images/graemlins/wink.gif" alt="" />

I bought one off eBay a about 6 months ago for my Prelude.
It's was a reman'd unit and it worked fine.

I'd check eBay, not only for reman'd units, but for take off's from wrecked vehicles.

I gave $179 for the reman'd unit and it works great.

Not too much else to tell ya, if you're having it recharged by a decent place just make sure they know that you changed the compressor, it'll need a new oil charge as well
