Getting over 20 degree temp split. Drain line is draining at this time. System is clean and operating as designed. Outside unit is level all electrical components are good and tight. Pressures were within manufacturer specifications. All components are operating as designed. Unit in good working order upon departure. Spoke with homeowner about surge protection.
