Overview
Mini-split systems are the right solution for spaces that don't have ductwork and can't easily get it — garages, room additions, sunrooms, converted attics, and detached workshops. They're also the best option for zone control in homes where one part of the house is consistently too hot or too cold.
We install ductless mini-split systems across Lago Vista and Travis County. We work with all major brands — Daikin, Mitsubishi, LG, Carrier, and others — and size systems correctly for the space being conditioned. A mini-split that's oversized short-cycles and doesn't dehumidify properly; one that's undersized can't keep up on a 100°F Lago Vista afternoon.
How It Works
A mini-split system consists of an outdoor compressor unit and one or more indoor air handlers (called "heads") connected by a refrigerant line set and electrical wiring. Unlike central AC, there's no ductwork — each indoor head conditions the space it's mounted in directly.
Single-zone systems serve one room or space with one outdoor unit and one indoor head. Multi-zone systems connect multiple indoor heads to a single outdoor unit, allowing independent temperature control in each zone. This is the most efficient approach for homes where different family members have different temperature preferences or where certain rooms have different solar gain profiles.
Compare Your Options
| System Type | Cost Range | Best For |
|---|---|---|
| Single-zone (9,000–12,000 BTU) | $1,800–$3,200 | Garage, small addition, sunroom |
| Single-zone (18,000–24,000 BTU) | $2,500–$4,500 | Large garage, studio, large addition |
| Multi-zone (2 rooms) | $3,500–$6,000 | Two rooms needing independent control |
| Multi-zone (3–4 rooms) | $5,500–$9,000 | Whole-home zone control |
Why Local Matters
We size mini-splits correctly — which most installers don't. Oversized systems are the most common mini-split installation mistake in Lago Vista. We carry Daikin, Mitsubishi, LG, and Carrier and recommend based on the application, not margin. All installations are permitted where required.
Real-World Example
Example Client
Homeowner in Lago Vista, 2-car attached garage used as home gym
The Problem
Garage reached 115°F+ in summer. Unusable from May through September.
What We Did
18,000 BTU Daikin single-zone mini-split. Outdoor unit mounted on side wall, indoor head on interior wall above garage door. Electrical run from main panel.
The Outcome
Garage maintains 72–75°F during workouts even on 100°F days. Customer uses the space year-round. Energy cost for the mini-split: approximately $45–$65/month during peak summer.
