Greeted customer upon arrival. Customer led me to attic and also thermostat that controls AC. Turned on the AC to see the condenser power on and it did. Full disconnect of condenser to wash condenser inside out. The watch condenser down with water and chemical. But condenser back together and plugged in the disconnect. Condenser powered on again put on field pieces to check pressures. I went to attic to look at the air handler. Took out filter of air handler and customer offered to wash it down it was a reusable/washable filter. What temperature probes in to check the difference in the temperature, Peak at 13 degrees. Pressure of the unit was fairly low on the high side. System was pretty low on refrigerant, offered a recharge or an estimate for another day of the same week, customer preferred to take an estimate instead of a recharging the unit. So customer status a pressure of the unit customer knowledge and signed off.
