Arrived on site for no cooling. Customer said that the unit can cool the house around late evening but during the day it struggles. Famous that would be set to 72 it would only be at 76 lowest. Air handler and condenser turned on normally. Inserted temperature probes and manometer into the unit. Hooked up a few piece gauges on the condenser to check out pressures. The pressure's on the unit were pretty low. Low side being 42 and high side being 220. Temperature difference inside the house was 10°. Recharged the unit with 3 lb and 3 oz of refrigerant. Low side went up to 103 high side went up to 270. Temperature difference was increased from 11 to 23, the supply vent went from supplying 62° to 48°. And gave a condenser outside a light wash from the outside with some chemical water to get better readings. Customer acknowledge of the job that was done today, recharging the unit, acknowledge and signed off.
