HVAC system with single piece body
HVAC system includes a front side access panel, an HVAC unit, a mounting sleeve, and a back side grille. The mounting sleeve and the HVAC unit are configured to fit within the preexisting framing of a building, and in particular to be mounted in a wall, between pre-existing studs, of a room. The HVAC unit can be installed into the mounting sleeve via quick connect mechanisms including, but not limited to, snap in connections and/or tab and slot features. The mounting sleeve enables rapid installation and also condensate collection. The HVAC unit includes an evaporator section, a mechanical section, and a condenser section that are integrally formed as a single physical unit. The design of the HVAC system is optimized to maximize space utilization and support efficient installation and servicing while minimizing product intrusion into living space.
