Arrived at the customer's house customer directed me to the condenser that is on the right side of the front house through the gate. Water access right next to the condenser. Customer also directed me that the unit is in the basement( air handler). Customer filter look new, he thinks he changed it. Customer has covered on condenser, inside condenser was clean. Clean condenser from outside with chemical and water. Put gauges on it, pressure was okay. Put temperature probes inside the unit, temperature split was 21°.
