Fan mounting assembly systems and methods

Abstract

A mounting assembly for a fan of a heating, ventilation, and/or air conditioning (HVAC) system includes a frame configured to couple to the HVAC system. The frame includes a support rail having a flange. The mounting assembly includes a first guide rail coupled to the frame and having a first lip extending at an oblique angle relative to the flange. The mounting assembly also includes a second guide rail coupled to the frame and having a second lip extending at the oblique angle relative to the flange. The first and second lips are configured to support and guide translation of a chassis of the fan toward the support rail such that the chassis of the fan engages with the flange. The flange is configured to support the fan offset from the first and second lips in an installed configuration of the fan with the mounting assembly.
