My car ac is not cold at all!?

i have a 2003 subaru wrx and it had a leak for the longest time that never got taken care of. now i finally fixed it(after a year or so) and the ac doesnt blow cold. there is no leak 100% sure, the relay is working properly, i reset the ecu to see if made a difference and the compressor is moving at full speed. i fell the noise of the compressor and feel how it takes power from the engine when i am inside of the car, but the air is barely less warm than the outside temperature. i ran out of ideas, please help. thanks!
