How do split systems and packaged systems differ in HVAC?

In the context of HVAC, split systems and packaged systems are fundamentally different in their configuration and installation. Split systems are characterized by having separate indoor and outdoor units. The indoor unit, typically located inside the building, is responsible for air handling and distribution, while the outdoor unit contains the compressor and condenser. This separation allows for more flexibility in installation and often results in quieter indoor operation because the noisy components are situated outside.

On the other hand, packaged systems consolidate all essential components—including the compressor, condenser, and air handler—into a single unit, which is usually placed on the roof or on the ground outside the building. This design makes installation simpler in certain applications where space is limited inside a building, as it does not require extensive ductwork between separate units.

Understanding this distinction helps in determining the best system suited for specific applications, influencing factors such as installation space, energy efficiency, and maintenance requirements.
