Performed furnace start up; inspected the exhaust and intake PVC ensuring all connections were secured we’ll have to return next year with spray foam to insulate the exhaust and intake PVC, sniffed the gas line for possible leaks, as well as cycled the system on and checked gas pressures and did make adjustments on both stages, also performed a combustion test verifying no CO in the airstream. This system is currently operating normal and heating at 47 degrees at this time. I did include a quote for an electronic air cleaner because i notice the du point allergen filter the air cleaner uses a positive electronic charge to help attract those fine particles down to .3 microns in size eliminating those particles that can upset allergies as well as included a quote for a humidifier replacement because the one in place now has a broken solenoid valve.
