> I researched how to diagnose them and do the easy fixes, ran into the EPA requirement, studied the material and got my EPA certification Please write more or make a video or something. I have been thinking very seriously about doing exactly this. HVAC is an absolute racket in my area, and nothing is ever a single-visit fix. If you don't sign up for their "maintenance plan" the fix mysteriously doesn't last very long.

Not much to say. Pass the 608 (home hvac) or 609 (automotive). Buy the refrigerant at supplier. You can buy an expensive R134a refrigerant recycling system like the one I own for 609, but you can also use a less expensive refrigerant recovery system that's functionally a vacuum pump with built-in manifold gauges and a tank or just a vacuum pump, manifold gauges, and a recovery tank. Easy fixes are on YouTube. I am looking into setting up a refurbishment service for broken AC electronics. To me, it's just a motherboard and I can fix them with my soldering station.
