If you are going to solder you should really use stay bright 8 silver solder it came hold up to high pressure , I wouldn't feel safe using any solder with 410 because the high side can get above 300 psi. It's called 8 because it has 8 percent silver in it.
Seems like you used lead solder made for plumbing, 410A can get up to 450 psi.. and should be solder with sil-fos or 95% silver rod, and you vaccum the system but when connecting your hose you had atmospheric pressure inside them so you vacuumed it in before filling the hose with gas.

You are right ! Soldering the pipes wasn't good idea.
This is one of the coolest DIY project video on TH-cam! Great work!
I’m a graduating AC student. Loved the video. I did not know you could solder An AC unit. We learned how to braze. Will it hold with R-410A pressure?
Soldering the pipes wasn't good idea because it can't hold the pressure of R410 gas, just use brazing.
Best to understand how ac system works.
Should add a TXV or perhaps experiment with an electronic control using EEV. But very cool.

WOW!!! Amazing Sir, you are really AWESOME!!!
Fantastic video man. You are very smart.
Great work.
Did the solder blow out under the 410 pressures?
leaking
Cool video
I would have used R 152a refrigerant
Fantastic your mind
Thanks
so the fan is blowing air backwards?
Both fans blowing the air toward outside the unit.
