Flushing the A/C system?
What are you frugal DIYers using to flush your A?C lines and condensers? So I gather that a gallon of mineral solvent to start follow by a A/C flush to finish. Do the flush guns require a hook up to an air hose? If you don't have "shop air" readily on hand, can you just pull up to a gas station? I imagine they would not be too happy with me flushing the A/C with their air. I called a few local A/C and radiator places, but everyone wants to do the complete A/C job, they don't just do the flush for me. What to do, buy an air compressor?

Acetone for the metal parts. It's cheap and effective and evaporates very quickly.
A/C flush for the rubber parts can be had in one-quart bottles at O'Reilly's or the Zone. Smells like citrus. It says it's solvent based but it's cheap stuff. Pour a little on pavement and it will literally take hours for it to evaporate. Acetone is gone in seconds. Luckily most of the system tubing is metal, so you can use mostly acetone. I went to a local refrigeration supply company and bought a nitrogen cylinder. The gas costs about $20, and the cylinder deposit was $125. The cylinder was pressurized to about 2300-2400 PSI, so you'd need a regulator. It lasts long enough to do a complete system flush and pressurize it to leak test.
