Mini-Split Installation in Mercer Island, WA
Zoned, whisper-quiet comfort without ductwork. Perfect for additions, ADUs, and rooms that never quite reach the right temperature.
A ductless mini-split is often the practical answer for Mercer Island's shoreline Point homes and other tight lots where running new ductwork isn't realistic given the island's grading and access constraints.
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
