Ductless Heating & Cooling for Austin Homes, Sunrooms, Garages, Historic Properties, and Hill Country Additions
Adding AC to a room without ductwork used to mean tearing open walls or living with a noisy window unit that spikes your Austin Energy or PEC bill. Modern inverter-driven ductless mini-splits deliver quiet, precise climate control to exactly the rooms you need — no ductwork required.
Whether you’re converting a garage in South Austin, finishing a sunroom in Westlake, upgrading a historic Hyde Park home, or fixing a hot upstairs bedroom in Round Rock or Cedar Park, our certified technicians handle it. Learn more about our company and master technicians.
What Is a Ductless Mini-Split?
A mini-split delivers conditioned air directly to specific rooms without ductwork, connecting an outdoor compressor to one or more indoor units through a small 3-inch wall penetration.
Why inverter technology matters: Traditional AC compressors blast at full power then shut off completely, causing temperature swings and high energy use. Inverter-driven mini-splits modulate speed continuously — like cruise control — for up to 30+ SEER2 efficiency and temperature control within half a degree, even in Texas heat.
When a Mini-Split Makes Sense
- Room additions & sunrooms — condition new square footage without straining your main system
- Garage conversions — turn an unbearable garage into a usable gym, office, or workshop
- Historic homes without ductwork — whole-home comfort without cutting into original walls or ceilings
- Stubborn hot spots — fix that one room central air can’t reach; compare against our central AC repair options

Electrical & Drainage Done Right
Mini-splits need dedicated 208/230V circuits. During your in-home evaluation, we run an ACCA Manual J load calculation and check your panel’s capacity — flagging any needed upgrade upfront. Every install includes code-compliant wiring, a weatherproof outdoor disconnect, surge protection, and leak-proof condensate drainage (with safety-switch backup pumps where gravity drains aren’t possible).
HOA & Curb Appeal
We install architectural-grade exterior line covers (multiple finishes, paintable to match your exterior) and position condensers discreetly to keep HOAs happy. Need documentation for an architectural review? We provide line-routing plans and spec sheets.
