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. Measured 20 degree temp split from supply to return. Drain line is draining at this time. System is clean. And operating as designed. Gas heat and safeties are working as intended without issue. Outside unit is level all electrical components are good and tight. All components are operating as designed. Pressures were within manufacturer specifications, however we will want to check pressures again when it is warmer outside to ensure proper change level. Unit in good working order upon departure. Thank you for your time.
