Multi-zone mini split systems allow you to connect multiple indoor units to a single outdoor compressor, giving every room its own independent thermostat. Your bedroom can be cool for sleeping, the living room warm for evenings, and the home office perfectly tuned for productivity — all at the same time.
Because you only heat or cool the rooms you're actually using, multi-zone systems are significantly more efficient than running a whole-home central system at a single temperature. For Seattle's older homes where adding ductwork isn't practical, they are the ideal whole-home comfort solution.
- Independent temperature control for up to 8 zones
- Mix and match indoor unit styles — wall, floor, ceiling cassette
- Only condition the rooms you're actually using
- Ideal for multi-story homes, additions, and open floor plans
- Highly efficient inverter-driven compressor technology
- Single outdoor unit keeps exterior aesthetics clean

Indoor Unit Styles Available
Every room is different — we help you choose the right indoor unit style for each zone.
Wall-Mounted
The most popular style — sleek, high on the wall, and easy to control. Ideal for bedrooms, living rooms, and offices.
Floor-Mounted
Mounted low on the wall for spaces with limited wall height, or for rooms where under-window placement is preferred.
Ceiling Cassette
Recessed into the ceiling for a nearly invisible look — perfect for living rooms, open-plan spaces, and commercial areas.
Ducted Mini-Split
A small duct system fed by a compact mini-split air handler — ideal for rooms where wall or ceiling units aren't practical.
