Mini-Split Installation Cost in Texas (2026): By Zone
Ductless mini-splits are a common fix in Texas for rooms central AC can't keep cool: garage conversions, additions, bonus rooms over a hot garage, and older homes without ductwork. A single head for one room is a few thousand dollars, and a whole-home system can cost as much as a new central system. Below are 2026 installed prices for Texas cities, a Dallas installer's published ranges and national cost guides.
| System | Typical installed cost |
|---|---|
| Texas statewide estimate | $3,700–$8,600 [1] |
| Houston | $3,500–$8,300 [1] |
| Dallas / Fort Worth | $3,600–$8,500 [1] |
| San Antonio | $3,400–$7,900 [1] |
| Austin | $4,400–$10,300 [1] |
| Single zone, 9,000–12,000 BTU | $4,000–$7,000 Dallas [2]; $3,000–$6,000 national [4] |
| Single zone, 18,000–24,000 BTU | $5,500–$9,000 Dallas [2]; $4,500–$8,500 national [4] |
| Single zone, any size | $2,000–$6,000 [3]; $3,000–$8,500, about $5,500 average [4] |
| Two zones | $9,000–$14,000 Dallas [2]; $6,000–$13,000 national [4] |
| Three zones | $13,000–$19,000 Dallas [2]; $9,000–$17,000 national [4] |
| Multi-zone, per zone | $2,000–$7,000 per zone [3] |
| Multi-zone total | $8,000–$18,000 for most systems [1] |
Where the sources disagree
The Dallas installer's numbers are the highest here. Its single-zone range starts at $4,000 [2], while national guides start at $2,000–$3,000 [3][4]. Its prices include a dedicated 240V circuit, line sets, condensate and startup [2], and it sells premium brands. National ranges more often leave the electrical work out [4]. The Texas city estimates [1] fall in between. Austin and Dallas-area suburbs such as Frisco run higher than San Antonio, El Paso or Lubbock [1].
What moves the price
- Number of zones. Each indoor head adds cost, but heads share one outdoor unit, so cost per zone drops as you add zones [3][4].
- Electrical. A new dedicated circuit and disconnect adds about $200–$600 [5]. A full panel needs more work. See electrical panel upgrade cost.
- Line set length. Runs beyond the standard 25 feet add about $100–$400 [5]. Long attic runs to second-floor rooms cost the most [5].
- Indoor unit style. A ceiling cassette adds $500–$1,000 over a wall unit, and a concealed slim-duct unit adds $500–$1,500 [2].
- Extras not always quoted. Permits ($150–$400), drywall repair ($200–$800 per access point) and old equipment removal ($300–$800) are often left out [2]. A condensate pump adds $50–$200 [5].
Practical tips
- Get every quote on the same terms: number of heads, BTU size per room, brand, and whether the circuit, permit and line-set cover are included.
- For a whole house with existing ducts, compare against AC and HVAC replacement cost in Texas before going ductless.
- If your central AC is struggling, a repair may solve the problem for less. See AC repair cost in Texas.
- Mini-split installs involve refrigerant and electrical work. See how to check a Texas contractor license.
