is it blowing evenly out of all the vents?

as I understand it these units are very picky on how much freon you add..as little as an ounce and it will not be right....never heard of any additive

35 pounds? 35 pounds of what? The capacity of the system is 24 OUNCES of refrigerant. If you meant 35 ounces the system is overcharged. No way could you get 35 pounds of refrigerant in.

Default About 2 cans of 14 oz refrigerant is about right
