Mini-Split Installation in Sammamish, WA
Zoned, whisper-quiet comfort without ductwork. Perfect for additions, ADUs, and rooms that never quite reach the right temperature.
Plateau homes with finished bonus rooms or additions that outgrew the original ductwork are some of our most common mini-split calls in Sammamish — a zoned, ductless system gets that one room back to a comfortable temperature without touching the rest of the house.
Symptoms we see every week
- One room that's always too hot or too cold
- Adding an ADU, addition, or converted garage
- Ductwork is impractical or too costly
- You want per-room temperature control
