Performed first year furnace cleaning; inspected the exhaust and intake PVC ensuring all connections were secured, i then removed and cleaned the burners along with the flame sensor, next I cycled the system on and checked gas pressures, as well as performed a combustion test verifying no CO in the airstream. Due to the amount of dust buildup on the blower wheel I do recommend upgrading to an electronic air cleaner to do a better job filtering out the dust in the air. This system is currently operating normal and heating at 45 degrees at this time. Job complete
