Garage mini split installation in Central Texas.

Updated September 2026

A Central Texas garage without ductwork hits 110°F in July and dips into the 30s in January—especially with an uninsulated door and west-facing sun. A single ductless mini split head turns that space into a year-round gym, workshop, or car bay. Our flat-rate installs include materials, labor, and a TDLR-licensed crew. Same-day standard installs are available along I-35 from Waco to New Braunfels, including Austin, Round Rock, Georgetown, and Cedar Park.

Flat pricing, same everywhere we work

Every install is wired to code by our TDLR-licensed contractor. Long line-set runs, panel upgrades or unusual mounting can add cost, and we tell you up front, before any work starts. For market context, see our Austin mini split cost guide: typical Central Texas quotes run $3,000 to $5,000 for a single zone.

Why Your Garage Needs a Ductless Mini Split

Garages are built without ductwork, and most have thin, uninsulated garage doors that bake in afternoon sun. Add a west-facing wall, and you get a heat trap that makes summer workouts or projects miserable. A ductless mini split—specifically a heat pump—solves both problems: it cools the space down to a comfortable 70°F in summer and provides efficient heat in winter, all without modifying your existing structure. It mounts on an interior wall or ceiling, requiring only a small hole for refrigerant lines, so you keep your floor space for equipment, weights, or tools.

What the Install Involves

Installation starts with mounting the indoor head on a wall or ceiling, running a slim line set to the outdoor condenser, and connecting the unit to a dedicated circuit or existing panel. Our crews handle the entire job—drilling the penetration, hanging the condenser pad or bracket, purging the lines, and testing the system. For a standard install with straight line runs and accessible attic or exterior walls, we complete the job the same day. No ductwork to build, no insulation to upgrade. You get a 1–2 ton unit sized for the garage’s volume and solar load.

Sizing and What Affects Pricing

We charge flat rates based on zones, not unit size, because most standard garages (up to 600 sq. ft.) take a single 12,000–18,000 BTU head—our $1,500 one-zone price. Two zones cover larger garages or a garage plus adjacent room for $2,500, and three zones handle a workshop, gym, and car bay for $3,500. Variables that can add cost: longer line sets (over 50 feet), non-standard electrical work (panel upgrade or subpanel), or challenging condenser placement (second floor or roof). We quote those before work starts. Most garage installs fall within the flat rate.

Questions

Will the mini split keep up with an uninsulated garage door?

Yes—if sized correctly. We match the unit’s BTU output to your garage’s square footage, ceiling height, and solar exposure. An uninsulated metal door adds heat gain, so we typically bump to a 15,000–18,000 BTU single-head system for a two-car garage. That’s still within the $1,500 one-zone price. The unit runs longer cycles to maintain temperature, but it stays efficient because mini splits vary their fan speed and compressor output.

Do I need to add insulation or upgrade my electrical panel first?

No. The mini split works fine without adding insulation—it just runs more often. We do recommend sealing gaps around the garage door if you notice drafts, but that’s optional. For electrical, a mini split typically needs a 15- or 20-amp dedicated circuit. If your panel has room for a new breaker, we wire it directly. If your panel is full, we’ll quote a subpanel or tandem breaker before install. Most garages in homes built after 1990 have the capacity.

What about loud gym equipment or sawdust in a workshop?

Mini splits are designed for continuous use and handle moderate dust and vibration. For a garage gym, the indoor head is wall-mounted away from drop zones—slamming weights or dropping barbells won’t damage it if mounted at least 12 inches off the floor. For a workshop, fine sawdust can clog the drain line and evaporator fins if the unit runs during heavy sanding. We suggest turning it off or using a dust-collection system during high-dust activities, and cleaning the filter monthly. Otherwise, these units last 10–15 years in garage environments.
