What is the main advantage of using split systems in HVAC?

The main advantage of using split systems in HVAC is the flexibility in installation. Split systems consist of two main components: an indoor unit and an outdoor unit. This design allows for greater versatility in how and where the components can be installed, accommodating various building layouts and space constraints. The indoor unit can be positioned in numerous locations inside the building, while the outdoor unit can be placed away from living areas, thereby minimizing the visual impact and the noise associated with the equipment.

This flexibility can be particularly beneficial in residential buildings where space is limited or where aesthetics are a concern. It allows for different configurations that can meet the specific heating and cooling requirements of a space without extensive modifications to existing structures.

In contrast, while lower initial cost, reduced noise levels, and energy efficiency are all notable benefits that may apply to split systems in some contexts, they do not match the primary advantage of installation flexibility that split systems uniquely offer compared to other HVAC options.
