i bought a artic freeze recharge kit so i could recharge my air conditioning. as of right now my a/c only blows hot air and when i attached the refrigerant the gauge was reading 25 then gradually going up to 45.. is there a way to empty the line so i can add new refrigerant to my car or any other way i can get air conditioning?

your pressure is correct, should read between 25 and 40 pounds on the low side with AC on and on high in the car. If you still only get hot air, listen to your AC compressor, it should be "clicking" when the clutch engages and pressurizing the system. If you do not hear it pressurizing, you need a new pressure switch would be my guess. If it does engage and dissengage, it should not do so rapidly in succession, this means there is not enough refrigerant in the system.
Otherwise, you may have a vacuum leak somewhere that is preventing the blend air doors in the dash to open/close to allow just cold air in. Just my 2 cents.
