Mini Split Installation in San Marcos, TX — Flat $1,500 for One Zone

Updated September 2026

If you live in San Marcos, you know what August does to a house. Garages turn into ovens by noon, back-house ADUs and casitas never quite cool down, and older homes near downtown have rooms the original ductwork never reached. A ductless mini split fixes exactly that kind of room — no new ducts, no attic surgery, just a quiet indoor head and a small outdoor unit.

ATX Mini Split King serves San Marcos and the rest of Hays County, including Kyle, Buda, Wimberley, Martindale and Dripping Springs. Our pricing is published, not negotiated: $1,500 for one zone, $2,500 for two, $3,500 for three — materials and labor included. Our own TDLR-licensed contractor does the work, most 1–3 zone jobs finish the same day, and we run and test the system before we leave your driveway.

Why we're the cheapest published price in San Marcos

A published flat price wins for one simple reason: you can compare it before anyone sets foot in your house. Industry-wide, ductless mini split installation commonly runs $2,000–$5,000 per zone — that's the real, citable range, and it's per zone, not per job. Meanwhile most local HVAC contractors, big-box store installation programs and national chains are quote-based: you call, you schedule an in-home visit, you wait, and only then do you learn the number. Quote-based pricing isn't automatically dishonest, but it does mean the price gets decided after someone has seen your house, your driveway and your zip code. Ours is decided before. One zone in a San Marcos garage is $1,500 — the same $1,500 across town or out toward Redwood, and the same $1,500 in July as in January.

Frequently asked — San Marcos

How much does a mini split cost in San Marcos?

With us it's published, not quoted: $1,500 for one zone, $2,500 for two zones, $3,500 for three zones, materials and labor included. For context, ductless mini split installation industry-wide typically runs $2,000–$5,000 per zone, and most San Marcos-area providers are quote-based, so you won't see their number until after an in-home visit.

Who is the cheapest mini split installer in San Marcos?

We'll only speak honestly about our own numbers: $1,500 for a single zone is our published flat price, well under the $2,000–$5,000 per-zone industry range. We can't tell you what any other Hays County contractor charges, because they don't publish prices — they're quote-based. What we can tell you is that you can compare our price right now, in writing, without scheduling anything.

Can you cool my garage or backyard ADU?

Yes — that's a big share of what we do in San Marcos. A single-zone system is usually the right fit for a garage workshop, a converted garage bedroom, or a small ADU or casita behind the main house. That's the $1,500 flat price, and if the wall needs touching up after the line-set penetration, we'll make a Home Depot run for matching paint as part of the job.

How long does it take, and who actually does the work?

Most 1–3 zone installs are finished the same day. The work is performed by our own TDLR-licensed contractor — not handed off to a rotating subcontractor — and we run and test the system with you before we leave, so you watch it cool before we're off your property. Older San Marcos homes with plaster walls or a full electrical panel can add time; we'll tell you that up front, not at the end.
