A/C Conversion Advice

[coop34]

I'm torn on whether to give up on my non a/c to a/c conversion or just bite the bullet and go with an aftermarket a/c kit (VA, Old Air, etc.)

I have a non a/c cab and purchased an a/c system on craigslist from a 70 chevy. (A/C box, condenser, old compressor, actuators, most of the brackets, etc.) I started the non a/c to a/c conversion by modifying the firewall and installing the a/c box with a new evaporator. The system I bought didn't come with the poa valve, and now I'm torn on how to finish this up. Do I go with a poa eliminator setup? Accumulator and orifice tube setup? Is it worth seeing if the old A6 compressor will work? Or should I go with a newer one? Any advice/help would be greatly appreciated!

My 2 cents. Put the orifice tube in and accumulator and never worry about it again. Mine works great. 38-40 degrees all day long man!Save your self time and money and don't install the crappy A-6 compressor. Go ahea and buy the kit from Classic air for the small sanderson compressor. It's worth every penny. Everything bolts right up to the truck.

Thanks Andy. Which kit are you referring to? Would I need to get a different evaporator? Would I need to have hoses made?

If you need a rebuilt poa valve, I have them. This way you don't need to buy another evaporator. You could also get an aluminum modern version of the steel a6.

My aftermarket old air kit sucks. It will be coming out this winter and replaced with a original ac system

Thanks for the tips. I'm leaning towards finishing up the factory A/C, but not sure about which compressor and valves. A6 or sanden? POA, POA eliminator with cycling, or accumulator/orifice tube setup. It gets well over 100 degrees here in the summer.

If you are installing a factory system, go with an aluminum aftermarket replacement for the A/6 that fits the brackets/hoses. Use R-12 and have a system that works as it was designed and will freeze you out of the cab idling in 100 plus degree weather. No need to change anything else. The cost of R-134 here is almost the same as R-12 anymore (which can be found at swapmeets, CL, and eBay)
