Understanding Ductless Mini Split Systems for Tiny Homes

How Mini Splits Work in Small Spaces

Ductless mini splits use a simple two-component system that’s perfect for tiny homes. An outdoor condenser connects to one or more indoor air handlers via a small conduit housing refrigerant lines, power cables, and a drain line. Unlike traditional HVAC systems that require bulky ductwork, mini splits transfer heat directly between indoor and outdoor units. The compact indoor handlers mount on walls or ceilings, taking up minimal space while efficiently cooling or heating your tiny home’s different zones.

Benefits of Ductless Systems for Tiny Living

Ductless mini splits offer unmatched space efficiency for tiny homes, eliminating the need for intrusive ductwork that would consume precious square footage. You’ll enjoy zone-based climate control, allowing different temperature settings in separate areas to maximize comfort and energy efficiency. Installation is straightforward compared to traditional HVAC systems, often requiring just a 3-inch hole in your wall. Most systems operate quietly at 32 decibels or less—essential in compact living spaces where mechanical noise can be intrusive and disruptive to your tiny home lifestyle.
