Performed Package clean and tune; inspected the condenser electrical compartment and tested components, sprayed the condenser with coil cleaner, cycled the system on and checked pressures and temps subcooling sitting at 8 degrees with an 18 degree temp split. System is currently operating normal at this time. Inspected the exhaust and intake PVC ensuring all connections were secured, removed and cleaned the burners along with the flame sensor, cycled the furnace on and checked gas pressures, performed a combustion test verifying no CO in the airstream system is heating at 46 degrees at this time. Recommend replacing #10 water panel in the humidifier before Fall. Also did want to mention the 20x25x4 filter is not the correct filter for the box I recommend using the correct aprilaire 213 filter this is to prevent any issues with possible warranty claims.
