multi-head split systems

For homes without ductwork, multi-head split systems are a practical alternative to traditional central air. You get a single outdoor unit that connects to two or more indoor heads, letting you cool or heat individual rooms independently. This setup saves exterior wall space while allowing different temperatures in different zones, like keeping the living room cool and the bedrooms warmer. It's a flexible solution for multi-room comfort without the need for extensive duct installation.
