Re: how do you refill an air con
With gauges you can simply watch the Temperature marks on the gauge... around 40 degrees F should be good. This is assuming the system was working and is still sealed. If any air or moisture got in, you'll need to have a pro come out and vacume it down.
When done you should have around a 25-30 degree drop across the A coil in the house.

ok first the blue hose onto the suction line(the thicker of the two pipes)of the ac unit,the yellow onto the vacuum pump.the red hose not necessary.After vacuum is completed remove yellow hose from pump and put it on gas bottle now you ready to charge the unit
Check the filter and be certain it is clean. close off any rooms that are not needed. then tell me the tempiture of the air in the room and the air comingout of the unit if you will. I think it is just doing all it can do though

hope answer the question
A charging hose or air con. gauges hook hose to low side of unit open vavle bleed off freon but i dont know why you would want to do that first you should hook up gauges to unit to read how much in pounds or onces you have in it your tag on unit will tell you how mucj the compressor will hold NOW law wise it is against the law to realease freon into air the laws are different in eack state you can release a small amount like when removing hoses most units are under charged not over unless some one put in too much if you have to bleed off some freon i it can be done. As far as removing all gas you should call a profesional with the proper recovery system.
