Abstract: Enclosed is information related to heating, ventilation and air conditioning (HVAC) improvements including modifiable air deflectors and more specifically to an improved air deflector capable of moving in relation to changing air patterns, ceiling heights and inhabitants preferences. More specifically the present disclosure relates to an improved air deflector apparatus that allows for the deflector to be adjusted for pivoting the deflectors but also to change the distance between the pivot point merely by sliding a damper guide along rails thus being further adaptable to the air pattern demands in a specific area.
