Performed the package cleaning. Furnace: Burners and flame sensor are clean. Heat exchanger looks okay. Combustion readings were normal. Drain lines are clear. No CO detected in the air. High limit passed the safety check. Temp rise was 69°. Only thing I found is the rust from what appears to be water damage awhile back. No standing water or leaks at this time. AC: No leaks detected. Electrical components tested good. Capacitor tested in the required zone. Condenser was cleaned with water and nu brite. Refrigerant charge was normal. Superheat was 11° with a 20° temp split. All HVAC equipment is operating properly.
