Free up more outdoor space with multi-split AC system

You can connect up to 4 indoor units to just one outdoor unit, reducing the need to place equipment outside your home or balcony. Compared to using multiple single-split systems (which require an outdoor unit for each indoor AC unit), multi-split systems free up more space and keeps your home exterior clutter-free. The multi-splits system is an excellent choice that eliminates the hassle and extra cost associated with installing multiple single-split systems
