Upon arrival I went into the attic and blew out the water removal system and sprayed drain pan treatment into coil pan as well as into the drain itself. Looked at blower wheel and motor and got voltages and amps for equipment. Placed probes in supply and return ducts to get temp split. Went outside and noticed there was a good amount of plant growth around unit. Recommended clearing it away to customer and she agreed. Got voltages and amps for outdoor equipment and checked capacitor and contractor. All working correctly. Washed down unit with water and used condenser cleaner for the top and electrical cover. System operating to manufacture specifications at this time.
