I saw R134A on the shelf at Advance Auto Parts for $8.99 per can which has gone up from last summer. That price difference is not unbearable and I get keep it cold now with legal R12. Yeah!

Now a question about the situation. I can get the compressor, expansion valve and dryer for $400 at Autozone, but I don't have shop air so I'm not able to blow out the condensor or evaporator, nor do I have a pump to vacuum the system out, so is it best to take it to a repair shop along with my R-12 ? Thanks--
