I completed a Job Continuation I Removed the furnace and return drop and added box to furnace. I Moved furnace 8” forward and 6” to one side to line up furnace directly below the plenum. I Moved return drop to Coincide with the shift of the furnace. Cfm for the AC has been set to its lowest setting of 1300 cfm/50 cfm lower than it should be. Next setting was 1600 cfm and too noisy. Furnace is more quiet and the customer could tell the difference. systems operating normally at this time
