About This Service
Ductless mini splits are the right answer for Bay Area homes with additions, converted garages, sunrooms, or rooms that a central system simply can't reach comfortably. A single outdoor unit can serve 1–5 indoor zones, each independently controlled and heating or cooling only when occupied. Modern mini splits reach 25–30 SEER2, making them among the most efficient HVAC systems available — and because there are no ducts to leak, the comfort is noticeably more consistent.

What's Included
How It Works
Zone Planning
We map which rooms need conditioning, assess wall/ceiling path for refrigerant lines, and recommend the right number of zones for your goals.
Head Placement
Indoor head location affects airflow and aesthetics. We plan placement to maximize coverage and minimize visible line sets.
Line Set & Electrical
We route refrigerant lines, sleeve wall penetrations, and run the dedicated electrical circuit — typically the most labor-intensive part of the install.
Charge & Test
We vacuum-purge the refrigerant lines, charge the system, and test every zone across heating and cooling modes before completing the visit.
Ductless Mini Split Installation FAQ
Can a mini split cool my whole house?
A multi-zone system can, yes. However, for whole-home coverage in a ducted house, a central heat pump is often more cost-effective. Mini splits shine for additions, ADUs, garages, and rooms the central system underserves.
How long do mini split installations take?
A single-zone mini split usually takes one day. A multi-zone system usually takes two to five days depending on the number of zones, accessibility, line-set routing, and overall installation complexity.
Where does the condensate water drain?
We route condensate to an existing drain line, exterior wall, or condensate pump if gravity drainage isn't available. We assess this during the in-home survey.
Can I add a mini split to my garage without a panel upgrade?
Often yes — single-zone mini splits draw 15–30A. We check your panel during the assessment. If a breaker is unavailable, we'll quote a sub-panel or breaker replacement.
Do mini splits work in cold weather?
Modern inverter mini splits rated to -13°F heat efficiently in any Bay Area winter. You will not notice a comfort difference compared to your gas furnace.
