Lennox - M# XC13-042-230-03 - S# 5810E30454 Completed a preventative maintenance. Took a temperature split and it was 20 degrees which is perfect. Customer did not have a filter he said he would change it when he get the new 20x25x4 filter. Poured water down on the evaporator coil and it was draining properly and the condensate pump is working. Then performed a amperage readings on the condenser fan motor, and compressor both are operating properly. System is operating properly properly at this point.
