Split System

This chapter introduces the fundamentals of Split Systems, a common HVAC solution for small to mid-sized commercial spaces. These systems separate the outdoor unit (containing the compressor and condenser) from the indoor unit (evaporator coil and air handler), offering flexible installation and quiet indoor operation.

Key topics include:

• Major components and their functions

• System diagrams and layout

• Typical sizes and use cases (offices, retail, etc.)

• Basic installation requirements (line sets, drainage, clearances)

• Routine maintenance and troubleshooting tips

The chapter is designed for HVAC techs, assistant project managers, and facility personnel seeking a clear, visual guide to how these systems operate in real-world applications. Includes embedded diagrams, real maintenance examples, and links to manufacturer videos and training.
