Found we have a 2 ton unit for the upstairs. The supply duct work comes out to 1500 cfm of duct work. I have concerns that the unit is undersized for the upstairs space. I’m going to get with the office on getting pricing for a load calculation. Office to reach out to Mr. Hoffman to get him pricing and scheduling. Supply ducts- 12,10,10,10,9,6 Return ducts- 16,10
