What is the difference between a split HVAC system and a packaged system?

The distinction between a split HVAC system and a packaged system primarily revolves around the configuration and placement of their components. A split system consists of two separate units: one located indoors, typically housing the evaporator and air handler, and another located outdoors, containing the condenser and compressor. This design allows for efficient cooling and heating within a space while keeping the noise and visual impact of the outdoor unit away from the living or working areas.

In contrast, a packaged system integrates all essential components—such as the compressor, condenser, and air handler—into a single unit, which is usually installed on the roof or a concrete slab beside the building. This arrangement is advantageous when there is limited indoor space for installation or when a more straightforward, all-in-one solution is preferred.

Understanding this configuration helps clarify why the correct answer highlights the separation of units in split systems compared to the unitary design of packaged systems. Each type of system has its unique applications and advantages, but the essential difference lies in how the components are arranged and connected.
