Ductless Mini-Split Service, done honestly in St. Helena.

Ductless mini-splits solve the rooms that central systems can't reach — the converted garage, the addition, the guest unit, the upstairs office that bakes every afternoon. In St. Helena, where guest houses and wine storage add zones that can fail quietly, mini-splits are often the practical answer we recommend.

We install, repair, and service ductless systems across Main Street cottages and multi-zone estate properties. Installation is about placement done right: head units where air actually circulates, line sets routed cleanly, condensate handled properly, and the outdoor unit positioned for airflow and long life through up-valley summers that run hotter than Napa proper.

Mini-splits are also heat pumps — efficient heating and cooling in one, and compliant with California's 2027 direction. For many St. Helena projects, a single-zone mini-split is the least invasive path to comfort in a problem room.

A mini-split is often the least invasive fix for a stubborn room in St. Helena — no ductwork to tear open, just a clean install done right. The details are what separate a good mini-split from a noisy, dripping one: head units placed where air actually circulates, line sets routed neatly, condensate handled properly, and the outdoor unit sited to survive up-valley summers that run hotter than Napa proper. We handle single-zone problem rooms and multi-zone whole-home systems alike, and because they're heat pumps, they align with California's 2027 direction too.
