Upon arrival customer showed me an ac unit in the garage that needed tuned up. Cleared the condensate with nitrogen and water. The evap coil is clean. Checked the system for proper amps and volts. For a 24 volt uv Bulb bad. Mentioned it to the customer and replaced the bulb. Went to the condenser and checked for proper amp and voltage. The capacitor is in good readings. We have a Delta T of 19 degrees
