Today a guy came into our shop with a small but brand new window AC unit. He was mounting it and managed to drill a hole into a tube on the condensor.
So we silver soldered the hole up, bought a line tap to charge it and used some R22 we had in the back. Thing works great!
Any idea what the pressures should have been? I just kept adding a little at a time till it got brrrrrrrrrrr cold.
On a window shaker your better off if you have a scale to weigh in the charge, but hey it looks like you did ok with your idea.

Don't take life seriously... Its not permanent.
I see lately they are putting on labels with the type and quantity of refrigerant. Seen guys drill holes in evaporators, condensers, and tubes before, wonder what they were thinking? Or in electrical wiring or in water pipes behind a blind wall. Or in a fuel line on a vehicle behind a sheet metal panel. Shouldn't you look first?
chris142 - Not having much experience at soldering, I have a few questions. Was the condenser tubing copper or aluminum? Did you have to trim away the fins to get to the hole? Do you clean-up the hole area with anything? What kind of solder? Can you use a "DIY torch"? Also, how much was the tap?
I have a similar problem....and thanks for the post.
The hole was on one of the elbo's...Right on the side of the condensor. Condensor was Copper. We use silver solder and it's special flux which is very strong. Brand new unit so it wasn't dirty. We use natural gas and oxygen here. Probly use a propane torch if no wind.
The tap thing was under $5 at the appliance store. Sticker said 7oz but I had no way of measuring it. Didn't want to acidentally goof up one of our machines so we just kept shooting in little bits till it got cold.
Those elbows at the ends of condensers are reaaly thin. If you need to solder a hole in them, here is a good trick. Get some clean stranded bare wire, wrap it around the elbow covering the hole. Silver solder it carefully. The wire will prevent the solder from closing the passage and causing a restriction.
