Wow, you've turned into quite the a/c guru! Good work.

I would only point out one thing, and it could be that I don't understand exactly what you did. If you pumped the vacuum and waited nine days, then charged, that's not the best plan. It probably is okay, and not a bad way to test an empty system for leaks. What would be best would be to evacuate again before charging.

The reason is that a system under vacuum will pull in air and moisture if there is even a tiny leak unlike a charged system which is under pressure so nothing can get in. Since the weather is hot, evacuating one last time before charging would have boiled off any slight moisture in relatively short order.

Just thought I would throw that in so you will know.

Congrats on a job well done,
