Performed furnace tune up 10 yr Goodman split system Folsom. Tested system, put system thru it’s stages, furnace running good at this time. Per client request look at drain line and secondary in attic. Pan is supported with 2by4 only on edges not in center pan sags. Would recommend sliding some center supports under pan. Not sure why pan is raised, just be for better slope. Pan and unit have float switch to kill power to unit if the pan fills with water. Checked gas pressure ok, cleaned burners and flame sensor. Variable speed motor ok changed filter for client. Hot surface ignitor ok. Black flex ducts sealed. slightly lifted unit and slide 2by4s under center of pan to support pan more. Slide one in from each side. Also renewed the membership for another year. Also cleaned off dirty hand marks on attic hatch as best I could.
