Came out today for QC visit on new install. Started inside at t-stat (Honeywell t6) turned system down to check over unit. System is level all wiring is good no error codes. 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. All components are operating as designed. Pressures were within manufacturer specifications. Tested normal heating operation. Tested drain line draining well at this time. Offered surge protection and labor warranty. Homeowner requested some time to think it over. System in good working order upon departure. Thank you for your time.
