If the unit was freezing the evaporator before you charged it and now you do not have cooling, you may have overcharged it. The best way to determine this is to have a certified AC technician check the actual pressures of the system as most do it yourself cans do not have acurate gauges. The compressor may run constantly, but not cool or the compressor may run and then blow a fuse or the compressor may run and there is no cooling, but the only way to acurately determine an overcharge is to measure the pressure with accurate gauges.
