Step back from the ledge………..

So you demonstrated that the unit works !

A lot less work in getting this one right, than installing roof units.

So find the leak, and decide what to do next. It wasn’t clear to me if you sourced a new coil or fixed the old one. Which was it?

And now you know how much to weigh in too. That almost 500 psi of head pressure didn’t do anything to help a leak. It really should have been less than 300.

Go easy on yourself, you are learning AC through experience, and there is a curve. I have been down a similar path, and there have been and still are some oh no’s. Given that the built in AC systems are a no man’s land, it pays to buy the equipment and learn to fix it on your own. A house tech won’t touch it, and an RV tech only replaces roof units.

I know you probably don’t want to hear this at this instant, but the one thing that I eventually purchased that took so much pressure off the AC work was a recovery unit. No puns intended. The ability to recover the refrigerant when something didn’t go right, made the work less stressful.
