An air distribution blower housing for an air handler such as a residential furnace is designed with an enlarged air outlet opening that slows down and spreads out the air flow from the blower housing over a greater area of the furnace heat exchanger. The blower housing thereby enables less air pressure drop through the heat exchanger, which increases the efficiency of the blower motor operation. The design of the blower housing also efficiently turns the velocity head of the air flow through the housing to usable static air pressure at the housing air outlet. The enlarged air outlet opening of the blower housing is achieved without increasing the exterior diameter dimensions of the blower housing whereby the blower housing is used in a compact enclosure for residential use. This is accomplished by utilizing a volute outer wall of the blower housing that has an exponentially increasing expansion angle in the direction of air flow through the blower housing.
