Abstract
A comfort system outdoor unit with a heat exchanger coil and a fan in its top opening has an orifice structure and an insert registerable with the orifice structure to streamline the inward flow of air that passes over a lower end of the orifice structure. The insert may be fastened directly to the orifice structure lower end, or it may be installed so as to extend substantially from an upper edge of the coil to the orifice structure lower end.
