A condenser coil and a method of manufacturing thereof, with an extended heat transfer surface attached to a serpentine coil such that the assembly can be folded into a U-shape cross section to allow for cross flow of air through and around the condensing coil. In one embodiment, wires are attached to the serpentine coil in a preliminary stage of manufacture across a width of the coil along its length and the coil is wrapped into a U-shape. In a second embodiment, a planar flat plate is attached to a serpentine coil and the coil and flat plate are wrapped into a U-shape. 14
