Does anyone know the address or phone number of a business in flordia that rebuilds poa valves or where to buy a kit that bypasses the poa valve and cycles the compressor? thanks, jack

There's a place in Fort Worth TX called Old Air Products 817-531-2665, and one in Tampa called Classic Auto Air 813-251-2356. (Area code might be 727, now) Don't know if they rebuild POA valves, but I think they have a conversion kit to eliminate them.

NAPA sells POA valves.

Just got done working on a '70 A/C unit. His water shutoff valve was bad along with a/c expansion valve stuck closed.

Changed out the expansion valve, and water valve, it worked great. Twelve dollars for the exp valve, $3 for the water valve,

Old Air Products is a nice place to visit,

Hey Jack,

I go in and change out the evaporator core. It's not that hard to change.

In doing this get an evaporator core for a 78 Olds 88. This should bolt right in and then you will have an orface tube system. No more stuck expansion valves, and jicky POA valves, just one little orface tube, that works fine.

Do the NAPA POA valves look like the original, or do they look like the "replacement" ones available at the resto houses?

The one I got from NAPA looked like OEM. Could have been NOS.

I have the poa eliminator on my daily driven 68. I live in AZ. I looked into the aftermarket poa's, they didn't look even close to the origional.
My AC is very cold, unless it's [email protected] out. If it's less than [email protected] it blows out at less than [email protected] i've seen [email protected] a few times.
It does warm up when you are driving 65-70 mph. I've havn't figured that one out yet.
I've tried to keep my car as factory new looking as possible, but I've had to many weird problems with poa's. The eliminator does not look unsightly.
The eliminator came from old air products, and has a cycling switch.

Thanks for the information. Dale, do you have a cowl induction hood on your car?

Dale, Exactly what does your evaporator area look like with the eliminator? Could you put a gutted POA valve in line for the "original" look? What about the expansion valve?

I have a cowl ind. hood, but I took it off and bought a repro SS hood.
The evap. area looks similar, I suppose you could gut a poa, and screw on a low pressure switch on the low side service port. Basically the eliminator is an aluminum tube with 2 service ports, one for service, the other for the low press. switch. There are no modifications to the evap., and the same expansion valve is used.
