Performed first year furnace cleaning; inspected the exhaust and intake PVC ensuring all connections were secured, removed and cleaned the burners along with the flame sensor, cycled sytem on and checked gas pressures and did make an adjustment, as well as performed a combustion test verifying no CO in the airstream. System is currently operating normal and heating at 51 degrees at this time. My only concern today is the amount of dust found on the blower wheel. Considering this system is only one year old we do have a substantial amount of dust of the blower wheel this could potentially result in a lesser efficient furnace. The 1in paper filter in place is not doing its job and it’s alowing dust to get passed it. I am including a quote for an electronic air cleaner to help bring these levels of dust down in the home.
