How did you know how much freon to add?

I'm betting you did not.

Must use gauges and know what you are doing to get the freon right.

I usually see people put the freon level to about "345" on the dial, but never over that.

I never used a guage when I refill the system with freon. Let the low pressure side suck in freon until it doesn't suck in any more. for a home job a guage is overkill as far as I am concern. His problem is probably the compressor clutch is not engaging. Take a hammer and give the compressor a whack may loosen a frozen clutch. Hey, this is home garage remedy. Let's not complicate the diagnostic.
