Why is my cars air conditioner not releasing cold air?

-I have a 2007 honda accord and after putting two cans of refrigerant the car still doesnt release cold air. I turned the car on and set the air conditioner on before connecting the gauge to the car and can. Help!Don't turn on the air conditioner again until a professional has put the correct amount of refrigerant in it. At 4 years old it either has a horrible leak or (more likely) you have added enough refrigerant to ensure serious damage to the compressor. It is not possible to properly charge an R134a system without special equipment, but it is easy to overcharge them and "slug" the compressor. As the source accurately puts it, "If you slug the compressor with liquid, not only can it cause premature compressor failure 鈥?it will."
Multiple things to check...

Ac/clutch not engaging

Or bad relay

Controls not working properly

Fuse

Over or under the freon pressure

Air or water in the lines (look for the check glass window)

Or may need to check for leaks...
Could be a condenser, receiver, drier, clutch, anything. Get it to a reputable A/C repair shop.
