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.

How It Works

01

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.

02

Head Placement

Indoor head location affects airflow and aesthetics. We plan placement to maximize coverage and minimize visible line sets.

03

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.

04

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?

Single-zone installs typically take 4–6 hours. Multi-zone systems take one to two full days depending on the number of zones and line-set routing 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.
