Installation, repair, and maintenance for ductless mini split systems across Southern California.
Mini-split systems are a compact and flexible alternative to traditional HVAC systems. They consist of an outdoor compressor unit and one or more indoor air-handling units, connected by refrigerant lines — with no ductwork required.
This makes them faster to install, less invasive, and far more energy-efficient than conventional central air systems. They provide individualized room-by-room temperature control, helping you reduce energy waste and utility bills.
Whether you need to condition a single room, add cooling to a home addition, or upgrade your entire home to a multi-zone system, OC Mini Splits has the expertise to get the job done right.

Mini-split systems are ideal for a wide range of situations where traditional ducted systems are impractical, expensive, or simply inefficient.
When different family members or occupants prefer different temperatures, a multi-zone system lets everyone control their own room without affecting others.
Older homes, historical buildings, or spaces that lack existing ductwork can now have efficient HVAC without major structural renovation.
Adding a garage conversion, accessory dwelling unit, sunroom, or basement? A mini split is the fastest, cleanest way to climate-control the new space.
Stop heating and cooling rooms nobody's in. Targeted zoned climate control means you only spend energy exactly where and when it's needed.
Server rooms, offices, retail spaces, and restaurants all benefit from the flexible, precise temperature control mini splits provide.
