Ductless AC systems installed, repaired, and maintained by licensed HVAC technicians. Serving Spring, TX and all surrounding communities.
Ductless mini split systems solve problems that central AC can't — and Spring TX's home stock creates plenty of them.
A mini split (also called a ductless AC or ductless mini split) is a heating and cooling system that doesn't require ductwork. The outdoor compressor connects directly to one or more indoor air-handling units via a small conduit through the wall. Each indoor unit cools or heats the space it's mounted in, controlled independently.
In Spring TX, mini splits solve several specific problems that come up regularly. Room additions, garage conversions, sunrooms, and casitas built without ductwork have no way to connect to the central system — a mini split is the cleanest, most efficient solution. Rooms over the garage that consistently run hot, home offices that need independent temperature control, and bonus rooms at the end of long duct runs that never get adequate airflow are all ideal mini split applications.
Room additions, converted garages, sunrooms, and casitas built without ducts — mini splits provide full cooling and heating without tearing into walls to extend ductwork, which can cost twice as much in an existing home.
Bonus rooms over garages, master bedrooms on the west side of the house, home offices with equipment heat loads — a mini split lets you dial in the temperature independently without cooling the whole house extra to compensate.
Modern mini splits achieve SEER2 ratings of 20–30+. Because they condition targeted zones rather than the entire house, they use significantly less energy than extending a central system to cover the same space — especially in Spring TX's 10-month cooling season.
For homes without any ductwork, or where full duct replacement would be cost-prohibitive, a multi-zone mini split system (one outdoor unit serving 2–5 indoor units) can replace the central system entirely — with zone-by-zone temperature control and higher efficiency.
What to expect for a fully installed ductless system in Spring TX.
| System Type | Capacity Range | Installed Cost | Best For |
|---|---|---|---|
| Single-zone (1 indoor unit) | 9,000–24,000 BTU | $2,500–$4,500 | One room, home office, addition |
| Single-zone high-efficiency | 9,000–24,000 BTU | $3,500–$5,500 | 20+ SEER2; long-term energy savings |
| 2-zone system | 18,000–36,000 BTU | $4,500–$7,500 | Two rooms or a large open area |
| 3-zone system | 24,000–48,000 BTU | $6,500–$10,500 | Three-room addition or full floor |
| 4–5 zone system | 36,000–60,000 BTU | $9,000–$15,000 | Whole-home ductless replacement |
Installed prices include equipment, labor, refrigerant, mounting hardware, linesets, and standard electrical connection. Long lineset runs (over 50 ft), second-story indoor units, and permit costs vary. Prices are mid-2026 estimates for Spring TX; call (281) 905-2414 for an exact quote.
Pre-charged "DIY mini splits" advertised online do not allow proper refrigerant charging, vacuum, or leak testing. Texas requires EPA 608 certification for refrigerant handling. An improperly charged system underperforms severely in Spring TX's heat and voids the manufacturer warranty. Professional installation ensures the system is sized, charged, and evacuated correctly.
Correct BTU sizing is critical — especially in Spring TX's climate.
Mini splits are sized in BTU (British Thermal Units): 9,000 BTU for small spaces up to ~350 sq ft, scaling up to 36,000 BTU (3 ton) for larger zones. In Spring TX, the calculation accounts for more heat gain than national averages because of intense summer sun, high humidity, and long cooling seasons.
As a starting point: 600–700 BTU per square foot for typical Spring TX rooms with average insulation. Adjust up for west-facing rooms, vaulted ceilings, many windows, or heat-generating equipment. Adjust down for north-facing rooms with good shade and insulation. Oversizing causes short-cycling and poor humidity control; undersizing means the unit can't hit setpoint on the hottest Spring TX afternoons.
Best for rooms 300–500 sq ft: home offices, master bedrooms, small garage bays. Most popular single-zone size for Spring TX room additions.
Covers 700–900 sq ft: large master suite, living room addition, small casita. Good for bonus rooms above garages that absorb heat from below.
Covers 900–1,200 sq ft: large open living areas, shop spaces, detached garages being converted to conditioned space in Spring TX.
One outdoor unit powers 2–5 indoor heads. Each head is sized independently for its zone. Total capacity = sum of all heads' BTU. Our techs calculate the load for each zone separately.

We repair and maintain all mini split brands in Spring TX — not just systems we installed.
The most common mini split failure in Spring TX. We locate the leak, repair it (or replace the damaged lineset section), pull the system to vacuum, and recharge to specification. Leak repair + recharge typically costs $300–$650.
Mini split indoor units have drain lines that can clog in Spring TX's humid climate. A blocked drain causes the unit to shut off on the overflow switch or drip condensate into the wall. We clear and treat the drain line during every service call and tune-up.
Electronic faults: temperature sensors, error code diagnosis, control board replacement. We carry common boards for Mitsubishi, Daikin, Fujitsu, and LG for same-day repair on most common faults.
Cleaning the indoor coil, washing the filter, checking refrigerant pressures, clearing the drain, inspecting linesets and electrical connections. Spring TX's pollen and humidity make annual cleaning important — dirty indoor coils dramatically reduce cooling efficiency.
In-home load calc, zone planning, written all-in price. Same-day service available.
