Mini Split Installation and Repair in San Diego

An outdoor unit connects to one or more indoor heads through a refrigerant line set and an electrical connection that pass through a small opening in the wall. Each head conditions the room it is mounted in, so there are no ducts to run.

Where a mini split makes sense

• A building with no ductwork, where running ducts would mean opening up walls and ceilings.
• A garage conversion, ADU or addition the existing system never reached.
• One room that never catches up with the rest of the building.
• Offices and small commercial spaces where one area needs cooling on its own schedule.

Single-zone or multi-zone

A single-zone system pairs one outdoor unit with one indoor head. A multi-zone system runs several indoor heads from one outdoor unit, each with its own control, so rooms that are used differently can be cooled differently.

What installation involves

Siting the outdoor unit, choosing the wall position for each indoor head, running the line set and the condensate drain through the wall, and connecting the electrical supply. The wall position matters: it sets the line run and where the condensate goes. Where the panel needs more room for the new circuit, panel upgrades are on our electrical list.

Keeping it running

The indoor heads have filters that need regular cleaning, and the coils behind them collect dust over time. A head that cools weakly, drips, or smells musty is usually asking for cleaning or maintenance. Maintenance, troubleshooting, repairs and removals are all on our air conditioning list, alongside installation.
