How Do Multi-Head Split System Air Conditioners Work?
A multi-head split system air conditioner works by using one outdoor compressor connected to multiple indoor units, each installed in a different room. This setup allows you to control the temperature in each room separately.
Instead of installing multiple outdoor units—one for each indoor unit—you only need one, making it perfect for properties with limited outdoor space or strict building guidelines. This also makes the system quieter and more energy-efficient.
