rebuild POA valve experiences

[William F.]

Would appreciate feedback on experiences with the rebuilt POA valves done by Classic Auto Air in FL. They say they do hundreds of them. I want it to be functional. Considering one of these vs a POA "upgrade" which eliminates POA and cycles compressor I've had good luck with one of these straight through replacements from Old Air in Texas on another 67, but of course, it would get a judging deduct.
Thanks

The guys in Florida have done rebuilds on several AC parts for me. Never disappointed

Re: rebuild POA valve experiences

I agree with Jimmy. Classic Auto Air have done multiple items for me and all worked great. Don H.

Had mine rebuilt and re-calibrated for 134a. A/C works great, no issues at all.

Re: rebuild POA valve experiences

Was incidentially talking to another knowledgeable NCRS member who said reman POA valves hadn't worked for him. Are your good experiences with reman ac products specifically POA valves, which I'm asking about, or other components? Any body know where I can get an original for at least reasonable price?
Thanks

Re: rebuild POA valve experiences

For me only the POA valve.

I also had good luck with their POA valve and their compressor. They actually kept a second core that I included, and I only paid $16 for their work. Keep in mind when converting to 134A that an original or smaller area condensor limits cold air output. They also sell a green o-ring kit that is also a change-over requirement. There is also the correct oil to use, and you should have "barrier" hose, that has a plastic liner so the smaller 134A molecules don't leak thru the hose walls. I learned all this from them.

Mine where suction throttle valves from a '64 & '65. They have always worked great after Classic Auto Air rebuild them. Don H.

Re: rebuild POA valve experiences

I called them a few weeks ago about rebuilding a '70 POA. They wanted $220 and 6 weeks. Each sounded excessive.

Re: rebuild POA valve experiences

Regarding the POA "update" kit which cycles the compressor clutch, look for Dom's post about this several weeks ago. He questioned if the A6 clutch is designed to handle on/off cycling.

And with non-computer cars, how can a constant idle speed be maintained with the AC cycling on/off?

What's the benefit? A marginal increase in fuel mileage? Does this offset the above questions, the non-original look and extra cost?

Re: rebuild POA valve experiences

The benefit is not increased fuel mileage. Advantage is that it eliminates the often troublesome POA valve. There's one for R12 and another for R134 I've read Dom's opinion, but don't really think that's a big issue. On the one sold by Old Air Products in Texas, you can adjust how much cycling you desire. I'v e had one on a '67 for 4 years; ac blows cold, no problems. But concerning whether $220 for a rebuild is excessive if you want to stay with a poa valve, cheapest new original one I've seen is $500-$600.

NOS may be that much. I'm looking at used but tested and "guaranteed" POAs. They maintain an original look and from the photos, the finish on many of them look good. They're $100 - $130 and will work with either R12 or R134.

Has anyone had experience with these?

Re: rebuild POA valve experiences

Why would a good poa valve be removed in the first place? Off a totaled Corvette? Yes, would like to hear experiences with these.

Re: rebuild POA valve experiences

Is a POA still coined as a Pressure Operated Absolute? It's been a while, thanks.

Re: rebuild POA valve experiences

If you have a '67 and up factory ac car, you'll learn more than you want about the poa valve since they're prone to stop working.
