US Patent 11635230 Heating, ventilation, and air conditioning curb assembly

A heating, ventilation and air conditioning curb assembly includes a curb that has a planar profile for positioning on a flat roof of a building. A heating, ventilation and air conditioning unit is included that has dimensions which are unequal to dimensions of the curb. An adapter is positionable into the curb and the adapter has dimensions sufficient to accommodate dimensions of the heating, ventilation and air conditioning unit. Thus, the heating, ventilation and air conditioning unit can be installed onto the curb. A power unit is integrated into the curb to supply electrical power to the heating, ventilation and air conditioning unit in the event of a power outage thereby ensuring the heating, ventilation and air conditioning unit continues to operate. A leveling unit is coupled to the adapter for leveling the heating, ventilation and air conditioning unit.
