What Is a Ductless Mini Split?
A ductless mini split consists of an outdoor compressor connected to one or more indoor air handlers — no ductwork required. Each indoor unit is controlled independently, so you only condition the spaces you’re using. Daikin systems offer SEER ratings up to 30+ and operate near-silently with multi-stage filtration — a significant benefit during Seattle’s pollen seasons.
Daikin cold-climate systems maintain full heating capacity down to 0°F, well below Seattle’s typical winter lows, making them a genuine year-round solution.
