Ductless Mini Split Services in Los Angeles

What is a ductless mini split?

A ductless mini split is a split-system air conditioner and heat pump that delivers conditioned air directly to a room without ductwork. An outdoor compressor/condenser unit connects to one or more indoor air handlers via a small refrigerant line set. Each indoor unit has its own thermostat, giving room-by-room temperature control that central systems can't match.

In Los Angeles, mini splits are especially popular for:

Older homes without existing ductwork (bungalows, Spanish-style, craftsman)
Accessory dwelling units (ADUs) and garage conversions
Room additions, sunrooms, and home offices
Homes where extending central ducts is impractical or too expensive
Upgrading individual hot or cold rooms while keeping the main system

Mini split installation in Los Angeles

A standard single-zone mini split installation in LA takes one to two days. Multi-zone systems with three or more indoor heads typically take two to three days. What goes into the process:

Load calculation — We size the system to your room's square footage, sun exposure, insulation, and ceiling height, not just a rule-of-thumb guess.
Outdoor unit placement — Selected for airflow, noise, aesthetics, and code setback requirements.
Line set routing — Refrigerant lines, power, and condensate drain routed as cleanly as possible. We offer custom-painted line-set covers for a finished look.
Permit pull — Required in most LA jurisdictions for new HVAC equipment. We handle the permit and inspection.
Rebate paperwork — Qualifying installs may be eligible for LADWP, SCE, TECH Clean California, and HEEHRA rebates. We handle the applications.
