Then you will need a jug of refrigerant the type that's in the unit. Next you might need a scale to weigh in th refrigerant. Now after all that you really shouldn't be putting gages on a unit to check the freon unless you really have done many checks before that. The reason, every time someone puts gages on a unit it losses a couple Oz's of freon which has to be calculated back in to the unit.
Probably should call a pro. Call me now or call me later it'll cost you more later when you F--- everything up.

LOL, the old "beer can method".

I once had someone tell me he used the "headlight method" when I asked what he meant he said he had the homeowners wife stand over a vent & he added until her headlights came on.

first and foremost, clean both the evaporator and condenser coils. improper air flow across those and you'll never get your charge right.

Start by reading/research, these guys have pointed you in the right direction as a DIY'er it's your job to dig into the books a bit

(I'm a DIY'er too, but am mildly annoyed at your questions, tone etc. toward the professionals here and how you portray us)
