Performed annual ac maintenance on 8 yr old Bryant split system. System is operating well as of now. Keep an eye on electrical whip, looks like something has chewed on it at some point. Also, keep an eye where primary drain line exits home, wood siding is beginning to rote. Put in pvc extension piece to prevent water from contacting siding. Secondary is on opposite side of garage. Note: Condenser has a 3-4 time delay because of sure switch Contactor. Refrigerant pressures ok at this time. All electrical connections tight and ok at this time. Gave unit a water bath.
