A heat exchanger housing support for supporting a heat exchanger or coil housing and accompanying ductwork in the installation of heating and air conditioning equipment. The heat exchanger housing supports are typically used in pairs and are each characterized by a vertically-oriented support leg having a longitudinal leg cavity for receiving a threaded rod, with an adjusting nut provided on the threaded rod and a bevel gear provided on the adjusting nut. A second bevel gear is mounted on the support leg for meshing with the first bevel gear on the adjusting nut and driving the threaded rod up and down. A bottom bracket is attached to the bottom end of the support leg for resting on a supporting surface and a top bracket is fitted to a top nut threaded on the upper end of the threaded rod for engagement with the heat exchanger or coil housing. Raising and lowering of the respective top brackets and the heat exchanger or coil housing using oppositely-disposed, spaced-apart heat exchanger housing supports is accomplished by manipulating the second bevel gear to drive the first bevel gear, rotate the adjusting nut on each of the two threaded rods and raise and lower the top bracket mounted on the threaded rods extending into the respective support legs. |
