1. A heating, ventilation, and air-conditioning (“HVAC”) system comprising:
a refrigeration circuit comprising a compressor, an outdoor heat exchanger, an expansion valve, and an indoor heat exchanger; and
a blower system comprising:
a first direct-drive blower that flows air over the indoor heat exchanger; and
a second direct-drive blower that flows air over the indoor heat exchanger, the second direct-drive blower being operable and positionable relative to the indoor heat exchanger independently from the first direct-drive blower such that the first direct-drive blower and the second direct-drive blower are at least one of positioned within a specified range of distances with respect to the indoor heat exchanger or within a specified range of distances with respect to each other so as to at least one of increase uniformity of a distribution of airflow over the indoor heat exchanger, define a predetermined distribution of airflow over the indoor heat exchanger, or reduce interference with air intake of one of the first and second direct-drive blowers due to the other of the first and second direct-drive blowers,
wherein the first direct-drive blower, the second direct-drive blower, and the indoor heat exchanger are positioned such that a ratio of a distance between midlines of widths of the first direct-drive blower and the second direct-drive blower and a distance between a central axis of either the first direct-drive blower or the second direct-drive blower and a vertical midplane of the indoor heat exchanger has a range of approximately 0.5 to approximately 4.
