Furnace cleaning: heat rise was 59. Air filter system was dirty so I changed out with customers extras. Air movement system was clean and clear of all debris and signs of concern. All wiring was clean and secure. Flame sensor system was clean and clear of all debris. Indoor voltage enhancement system was running at 11.7uf. Factory spec is a 12.5uf so I informed the customer and I’m giving them an estimate. Flame gateway system was clean and clear of all debris and signs of concern. Cleaned off inside and outside of indoor unit. System was up and running at normal operation at the end of the visit.
