Ductless Mini-Split Installation in Houston, TX
Room-by-room cooling for garages, additions, and homes without ducts.
Ductless mini-splits solve Houston’s hardest cooling problems: garage conversions, sunrooms, additions, upstairs bedrooms that never cool down, and the many pre-1960 homes in the Heights, Montrose, and Garden Oaks that were built without ductwork at all.
A mini-split installs with a 3-inch wall penetration instead of ductwork, runs whisper-quiet, and gives each room its own thermostat. Modern inverter units also heat efficiently in winter, replacing space heaters for pennies on the dollar.
What’s included in every ductless mini-split installation
- Room-by-room load sizing and indoor head placement planning
- Single-zone and multi-zone (up to 5 heads per outdoor unit) configurations
- Line-set routing with clean exterior covers — no exposed refrigerant lines
- Dedicated electrical circuit coordination
- Condensate drain routing that will not stain brick or siding
- Wi-Fi control setup and homeowner walkthrough
- Permit and manufacturer warranty registration
When Houston homeowners call us for ductless mini-split installation
Garage or attic conversion
Extending central ducts into a converted garage almost always starves the rest of the house. A dedicated mini-split is the correct fix.
One room is always hot
West-facing bedrooms and rooms over garages often need their own zone — a single-head mini-split solves it for a fraction of re-ducting.
Older home without ducts
Pier-and-beam and pre-war homes can get whole-home comfort without tearing into walls and ceilings.
Home office or workshop
Cool the space you actually use all day without paying to over-cool the whole house.

Ductless Mini-Split Installation questions
Can a mini-split cool a whole house?
Yes — multi-zone systems with 3–5 indoor heads regularly handle entire homes, especially open-plan layouts under 2,000 sq ft. We size each head to its room.
Do mini-splits work in Houston humidity?
Extremely well. Inverter-driven mini-splits run long, low-power cycles that remove more moisture than a conventional system’s on/off cycling.
How long does installation take?
A single-zone install is usually a half day. Multi-zone systems typically take one to two days depending on line-set routing.
Are mini-splits efficient?
The most efficient option we install — many models reach 20+ SEER2, and because there are no ducts, you avoid the 20–30% duct losses typical in Houston attics.
