Came out today for QC visit on new install. Started inside at t-stat (Honeywell) 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. Unit in good working order upon departure. Thank you for your time. Performed air flow balance to get more even distribution of air. Customer was happy with the changed and I explained to him that this is probably as good as we can get it due to how the existing ductwork was put together. 4 ducts running off of the same duct run.
