A drain pan for an air handling unit including a base, a lip attached to the base wherein the lip extends substantially vertically from the base, and a riser affixed to the base wherein the riser extends substantially vertically from the base to support the air handling unit. The drain pan may further include a riser that is preformed with the base to form a unibody drain pan.

1. A secondary drain pan configured to be placed under an air handling unit to secure and drain any excess condensate that overflows from a primary drip pan of the air handling unit and to support the air handling unit apart from any drainage, the secondary drain pan comprising: a base; a lip extending upward from a perimeter of the base, the lip securing drainage on the base; at least two risers extending upward from the base and substantially across the base, each riser having riser portions comprising: side walls that extend upward from the base, a bottom of the side walls turning into the base such that an inner surface of the riser portions turns outward to form a bottom surface of the base; an upper support surface capable of supporting at least a portion of the air handling unit thereon, an outer surface of the side walls turning laterally inward to form the upper support surface; and at least one rib disposed along the side walls that increases load-bearing ability of the riser; and a supportive structure disposed between the riser portions, the supportive structure having less height than the riser support surfaces; wherein the upper support surface is wider at the at least one rib; wherein the riser portions about the at least one rib comprise a substantially frustoconical cross-section; wherein the riser portions connect at an angle such that the riser portions form one longer riser, wherein a distance between the risers varies along a length of the at least two risers; each riser enclosed from above and from the sides, limiting air or water from passing through the riser so that any drainage descends to the base, the upper support surfaces positioned above the lip to support the air handling unit above the lip and apart from any drainage on the base; wherein at least a portion of the side walls of each riser and at least one end of each riser tapers to the base such that drainage on the base may flow around the at least one end such that a drainage opening interfacing the base through the lip allows the drainage to flow freely out of the base; wherein the base, the lip, the at least one rib, and the risers are molded as a unibody drain pan with integrated support; wherein at least the risers are shaped to be nestably stackable with risers of another similarly shaped secondary drain pan; and wherein the riser portions comprise conical sharps, pyramidal sharps, rectangular sharps, triangular sharps, or a combination thereof. 2. The secondary drain pan of claim 1, wherein the secondary drain pan comprises plastic. 3. The secondary drain pan of claim 1, further comprising at least a third riser that extends upward from the base and extends across a center of the base. 4. The secondary drain pan of claim 3, wherein an upper support surface of the third riser is a different length than a length of the upper support surfaces of the at least two risers. 5. The secondary drain pan of claim 1, wherein the at least two risers are symmetrically opposed. 6. The secondary drain pan of claim 1, wherein the lip extends approximately two inches from the base and a base length is approximately twice a base width. 7. The secondary drain pan of claim 1, wherein at least portions of each riser originate from the same plane in the base. 8. A secondary drain pan configured to be placed under a condensate producing unit to secure and drain excess condensate that overflows from the condensate producing unit and to support the condensate producing unit, the secondary drain pan comprising: a base;a lip that extends upward from a perimeter of the base to secure drainage on the base;at least two risers that extend upward from the base, each riser running substantially from one side of the base to the other side of the base, a distance between the at least two risers varying along a length of the at least two risers, each riser comprising: side walls that extend upward from the base,an upper support surface capable of supporting at least a portion of the condensate producing unit, the upper support surface extending laterally inward from the side walls;wherein at least a portion the side walls and at least one end of each riser tapers to the base such that drainage on the base surface may flow around the at least one end such that a drainage opening interfacing the base at any place on the lip near a top surface of the base allows that drainage to flow freely out of the base; anda plurality of ribs disposed along the side walls of the at least two risers, wherein the plurality of ribs increase drain pan strength; anda supportive structure disposed between the at least two risers, the supportive structure having less height than the riser support surfaces;wherein the bottom of the riser is wider at the plurality of ribs;wherein the at least two risers about the plurality of ribs comprise a substantially frustoconical cross-section;wherein each riser is enclosed from above and from the sides, limiting air or water from passing through the riser so that any drainage descends to the base, the upper support surfaces positioned above the lip to support the condensate producing unit above the lip apart from any drainage on the base;wherein at least the risers of the secondary drain pan are shaped to be nestably stackable with risers of another similarly shaped secondary drain pan;wherein the base, the lip, the plurality of ribs, and the risers are molded as a unibody drain pan providing integrated support;wherein the at least two risers comprise conical shapes, pyramidal shapes, rectangular shapes, triangular shapes, or a combination thereof. 9. The secondary drain pan of claim 8, further comprising at least a third riser that extends upward from the base and extends across a center of the base. 10. The secondary drain pan of claim 9, wherein an upper support surface of the third riser is a different length than a length of the upper support surfaces of the at least two risers. 11. The secondary drain pan of claim 8, wherein the at least two risers are symmetrically opposed. 12. The secondary drain pan of claim 8, wherein a distance between the risers at their ends is different than a distance between the risers at their centers. 13. The secondary drain pan of claim 8, wherein at least one of the risers begins at a first corner of the base, runs toward a center of the base, and then turns to a second corner of the base that is on the same side as the first corner. 14. The secondary drain pan of claim 8, wherein the lip extends approximately two inches from the base and a base length is approximately twice a base width.
