Upon arrival customer showed me an ac unit in the attic that needed to be tuned up. The evap coil is clean. Cleared the condensate line with nitrogen and water. Checked the system for proper amp and voltage. The run cap was a little week but still in it range. Went to the condenser and checked the system for proper amp and voltage found a week 40/5 capacitor and replaced it with a turbo 200. The contactor was pitting and I replaced it also. Add a surge protector. We have 18 degree delta T
