  • The presently disclosed embodiments generally relate to heating, ventilation, and air-conditioning (HVAC) systems, and more particularly, to an auxiliary heating assembly for use with residential air handlers.
    • BACKGROUND OF THE DISCLOSED EMBODIMENTS
  • Residential air handlers may include auxiliary heating packages to provide supplemental heat when the residential air handler alone cannot satisfy the heating demand. In some instances the auxiliary heating packages are integrated within the residential air handler, and in other instances, the auxiliary heating package is enclosed in a separate compartment, typically on top of the residential air handler. Generally, the auxiliary heating package contains electrical heating coils arranged in linear rows. When used with a residential air handler having an axial fan, this linear arrangement could adversely affect the operation of the residential air handler as minimal air would pass through the center section of rows; thus causing temperature limits to be activated. There is therefore a need for an auxiliary heating package that will not adversely affect the operation of a residential air handler having an axial fan.
