A blower of an HVAC system includes an air inlet, an air outlet, a blower wheel with blades, a motor operable to cause the blower wheel to rotate, and a blower housing within which the blower wheel is positioned. The blower housing includes a top panel, a bottom panel, and a connecting panel. The top panel and the bottom panel are connected to the connecting panel. The top panel includes a curved edge extending from a bottom edge of the connecting panel to a top edge of the connecting panel. An expansion angle of the curved edge of the top panel changes as a function of position along the curved edge of the top panel. The bottom panel may have a shape corresponding to a mirror image to that of the top panel.
