Yes.. if you overcharge the system, then there isn't enough of a differential in pressures between the high and low sides of the A/C system and the it will not blow as cold as it would with a properly filled system. A low pressure gauge while installing is better than none. Without a pressure gauge, I've added just enough to keep the low pressure switch from kicking in and making the compressor cut out. If you use that method then give it a good couple of minutes of running before deciding it's had enough for all of the pressures to equalize in the system.. It may run ok a while, but when it equalizes, it may start cutting out again.
