Ductless Mini-Split Service in Sonoma

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 Sonoma, where decades of patched ductwork are common in older homes, mini-splits are often the practical answer we recommend.

We install, repair, and service ductless systems across Plaza-era historic homes and mid-century ranches. 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 valley heat that builds all afternoon.

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

Sonoma questions, honest answers

How much does a mini-split cost in Sonoma?

Single-zone installations typically run considerably less than full central replacements; multi-zone systems scale with the number of rooms. We quote after a free assessment — call (707) 531-9216.

Do mini-splits heat as well as cool?

Yes — they're heat pumps. One wall unit both heats and cools its zone efficiently, which suits Sonoma's climate well.

Straight with you: we don't keep an office in Sonoma — we're a family team based in Napa Valley serving Sonoma on scheduled routes, with same-day priority for emergencies. Our arrival windows already include the drive.
