I have an overhead Air Condition Unit, it has 11 vents and I would like to close down 2 vents. Also cut down the air from 3 others. Will this hurt the system?

Can you supply a brand and model number? It should be OK but I'd like to research it further

All I know is it is a Carrier Unit and about 20 years old.
