I completed A diagnostic service call Customer stated AC system stopped working while they were away from home. I checked filter and verified the air handler blower turned on. At outside coil I found a mouse nest inside behind the plate where contactor resides. the Mouse chewed up one of the Wires going to the contactor. I repaired wire to the contactor. I also cleaned out contactor area and checked capacitor. Capacitor was 45/5, Actual readings was 44.7 and a 4.56. I verified the contactor functionality which seemed acceptable in spite of a mouse being in there. I also checked refrigerant levels which indicated a low charge. I Discussed options with the customer however the customer decided not to do anything at this time. Customer signed up for a SMA agreement therefore I waived the diagnostic fee. System was operating upon text departure.
