Service call for little airflow to 2nd floor son’s room. Customer said that his son’s room seems to be hotter than other rooms on the 2nd floor. There are 2 vents in this room that have good air flowing coming out of the vents and the temperature is around 45 degrees. I checked the dip switches and on the control board to check airflow and to make sure it was set up correctly. airflow and all dip switches are set up correctly also dampers to both of these supply’s in the attic are fully open. The air flow could be adjusted slightly higher. Customer did not want to adjust the air flow due to other parts on the 2nd floor being ok. System is operating there are currently no faults.
