Answer: Yes, you can. But if you are using register as return grille then you should remember that damper should be open 24x7. A register comes fitted with damper to regulate the flow of air coming from the HVAC. If the damper is closed in return duct, then machine will work hard to suck up the stale air of the room. Similarly air return grilles can be fitted in the supply duct. You will not need dampers if the room remain occupied round-the-clock. But in case it remains unoccupied at most times then you can use independent louver assemblies that install in the duct behind the grille. These can be purchased separately.
