A heat exchanger unit includes a support assembly having a support surface extending in a first plane and a heat exchanger coupled to the support surface and fixed relative to the first plane. The heat exchanger includes a first manifold and a second manifold extending in spaced relationship with one another and a plurality of tubes spaced from one another and extending between and engaging the first manifold and the second manifold. The tubes communicate fluid between the manifolds. At least a portion of each of the tubes extend angularly relative to the first plane for draining condensate along the tubes toward a common drainage point to remove the condensate from the tubes and focus the condensate to the common drainage point. The drainage of the condensate from the tubes prevents the freezing of the condensate on the tubes to prevent the blockage of air movement over the tubes by frozen condensate.
