How do I bleed excess refrigerant from my car?

When Releasing excess refrigerant from a car you are basically left with three options.

Release the air using a $1,200 recovery unit, take it to a Certified ASE technician and have them do it right to the car's specific recomendations. The last option I personally do not recomened to anyone which is releasing the refrigerant into the atmosphere.

Buy a set of manifold gauges, find the correct amount of refrigerant the car requires and keep releasing until the correct measurment is acheived. All together the illegal way is about $1,165 cheaper unless someone reports you and the EPA slaps the individual with a $10,000 fine.
