Arrived on site, homeowner stated all was well with system operation to her knowledge. I asked if she had addressed the plumbing issues from the last time I was here and the homeowner stated she had the vent pipe replaced, and then the clog removed. Started inside at t-stat (Honeywell original) 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 well. Added a small amount of insulation to the p-trap where I noticed a little condensation. Plenum and filter are very dirty recommend duct cleaning. Outside unit is level all electrical components are good and tight. Start and run amps are within manufacturer specifications. Both indoor and outdoor fan motor are testing within manufacturer specs. All components are operating as designed. Pressures were within manufacturer specifications. Tested gas heat components and heating itself and found no issues. Unit in good working order upon departure.
