A/C not cooling sufficiently

[budweiser29]

My a/c doesnt seem to be running as effectively as it should. The suction line is not very cool and is not sweating at all. My filter is clean, A-coil is not icing up and the drain is not clogged, water is trickling out. Blower is running at normal speeds. My guess is it is low on charge (for whatever reason)...the house is approx 12 years old.

My pressure readings -
Low-63
High-220
suction line temp 6" from service port-67.4f
Outdoor - 86f
Indoor - 80f

Please let me know what you think. Thanks!

subtract the temperature the gauge needle is sitting on for your refrigerant (r22) from your suction line temp. this is the superheat. that number is too high. you have a leak......probably in your evaporator coil.
