Set the thermostat to Off so no air is moving.
Lift each floor register out of its hole. Undo the screws of wall and ceiling grilles.
For a ceiling grille, use a step stool, not a chair.Vacuum as far into the opening as the hose reaches, and pick out anything that's fallen in.
Wash the registers in warm soapy water and dry them.
Vacuum the big return grilles on both sides, and the opening behind each.
Set every register back with its louvers open, and nothing on top of it.
