The high side pressure needs to be measured to properly evaluate the situation.

Did you evacuate the air before recharging? If you take apart a system and then just dump refrigerant in without using a vacuum pump to get the air out of the lines first, you end up running a mixture of air and refrigerant which will not cool properly.

Did you add or remove any oil? Always charge an empty system by weight starting from a deep vacuum. Use the manufacturer's specified amount of refrigerant measured by weight.
