An air handler system comprising a cabinet housing a blower unit and a heat exchange unit. The blower unit and the heat exchange unit are located in a substantially same lateral dimension in the cabinet. The blower unit and the heat exchange unit are separated by a distance that provides for a substantially uniform flow of air through a vertically-orientated plane of the heat exchange unit when the blower unit is in operation.

1. An air handler system, comprising: a cabinet housing a blower unit and a heat exchange unit, wherein the blower unit and the heat exchange unit are located in a substantially same lateral dimension in the cabinet,the blower unit and the heat exchange unit are oriented in the cabinet such that air enters the cabinet along an air-intake pathway direction, through the heat exchange unit and into the blower unit, and, exits the blower unit and the cabinet in an air-output pathway direction, wherein the air-output pathway direction is perpendicular to the air-intake pathway direction, anda surface of the blower unit having an air-intake, through which the air enters the blower and travels along the air intake pathway direction, is separated from an opposing surface of the heat exchanger unit having an air-exit through which the air exits along the air intake pathway direction. 2. The system of claim 1, wherein, at least about 50 percent of the area of the opposing surface of the heat exchange unit overlaps in the lateral dimension with the surface of the blower unit. 3. The system of claim 1, wherein, at least about 90 percent of the area of the opposing surface of the heat exchange unit overlaps in the lateral dimension with the surface of the blower unit. 4. The system of claim 1, wherein, when the blower unit is operating, a distance separating the opposing surface of the heat exchange unit and the surface of the blower unit provides for a velocity of air, passing through any individual sub-area portion of the air-intake of the blower unit is within 30 percent of a velocity of air passing through any other individual same-sized sub-area portion of the air-intake of the blower unit wherein the individual sub-area portion and the other individual sub-area portion each correspond to about two-percent or higher of the total area of the air-intake of the blower unit. 5. The system of claim 4, wherein, when the individual sub-area portion corresponds to a 4 square inch area of the air-intake of the blower unit. 6. The system of claim 1, wherein, when the blower unit is operating, a distance separating the opposing surface of the heat exchange unit and the surface of the blower unit provides for a volume flow velocity of air, passing through any individual sub-area portion of the air-intake of the blower unit, that is a value within a range of about 400 to 800 cubic feet per minute. 7. The system of claim 1, wherein, when the blower unit is operating, a distance separating between the opposing surface of the heat exchange unit and the surface of the blower unit provides for an average volume flow velocity of air passing through the air-intake of the blower unit equal to at least about 400 cubic feet per minute. 8. The system of claim 1, wherein the distance is at a target value within about ±0.5 inches in a range of about 2 to 4 inches. 9. The system of claim 1, wherein the heat exchanger further includes louvered fins. 10. The system of claim 1, wherein the opposing surface of the heat exchanger is in a substantially same lateral dimension as a return air duct of the cabinet. 11. The system of claim 1, where the blower unit includes a centrifugal blower. 12. The system of claim 11, where a rotating drum of the centrifugal blower is oriented such that the axis of rotation of the drum is perpendicular to the opposing surface of the heat exchange unit and air output from the centrifugal blower along the air-output pathway direction is directed to an air duct located on a top surface of the cabinet. 13. The system of claim 1, where the blower unit further includes an electrical heater unit. 14. The system of claim 1, wherein the cabinet is configured as a wall-mounted cabinet. 15. The system of claim 1, wherein the cabinet has a vertical height of about 30 inches or less. 16. The system of claim 1, where the cabinet is configured to be located in a closet, wherein the ceiling height of the closet equals about 8 feet. 17. A method of manufacturing an air handler system, comprising: providing a cabinet;attaching a blower unit to the cabinet; andattaching a heat exchange unit to the cabinet, wherein the blower unit and the heat exchange unit are located in a substantially same lateral dimension in the cabinet,the blower unit and the heat exchange unit are oriented in the cabinet such that air enters the cabinet along an air-intake pathway direction, through the heat exchange unit and into the blower unit, and, exits the blower unit and the cabinet in an air-output pathway direction, wherein the air-output pathway direction is perpendicular to the air-intake pathway direction, anda surface of the blower unit having an air-intake, through which the air enters the blower and travels along the air intake pathway direction, is separated from an opposing surface of the heat exchanger unit having an air-exit through which the air exits along the air intake pathway direction. 18. The method of claim 17, wherein attaching the heat exchange unit to the cabinet further includes incrementally adjusting a distance separating the opposing surface of the heat exchange unit and the surface of the blower unit, and for each incrementally adjusted distance, measuring the velocity of air passing through different sub-area portions of the air-intake pathway direction exiting the heat exchange unit when the blower unit is in operation. 19. The method of claim 18, wherein adjusting the distance includes incremental adjustments of about 0.5 inches or less. 20. The method of claim 17, wherein attaching the heat exchange unit to the housing further includes adjusting an angle of the opposing surface of the heat exchange unit to a value in a range of about ±5 degree of a perpendicular angle with respect to a horizontal base of the cabinet.
