Ductless Mini Splits in Castle Hills
Zoned ductless comfort for Castle Hills' mid-century ranches on big wooded lots — aging systems replaced without tearing into finished homes.
Do we serve Castle Hills?
Yes — and Castle Hills homes are built for ductless
Yes — Castle Hills is inside our north-central service territory. Its 1950s–1960s ranch homes on large, oak-shaded lots are at the age where original or second-generation central systems are giving out, and their long single-story footprints are hard for one thermostat to balance. Ductless lets owners fix the worst rooms first — or replace an aging system zone by zone.
The housing stock, honestly read
Castle Hills grew as a mid-century enclave off Loop 410 and NW Military Highway — predominantly single-story ranch homes from the 1950s and 1960s on half-acre-scale lots, many carefully maintained or renovated by long-term owners.
Sixty-plus-year-old homes carry sixty-plus-year-old duct paths: long runs, leaky joints, and rooms at the far end that never keep up. Rather than re-duct a finished home, a ductless zone serves the far bedrooms, the added sunroom, or the converted garage directly.
The comfort problems we solve in Castle Hills
The far end of the ranch
Long single-story layouts put bedrooms a long duct run from the air handler. A dedicated head serves the far wing directly — no duct losses, its own setpoint.
Aging systems, staged replacement
Many Castle Hills systems are past their design life. Owners retire them in stages with ductless zones — spreading cost and avoiding a single disruptive changeout.
Sunrooms & garage conversions
Mid-century homes here have accumulated sunrooms, hobby rooms, and garage conversions. Each gets a right-sized zone instead of leaning on a central system that was never designed for it.
Quiet for wooded-lot living
Modern inverter condensers run dramatically quieter than the mid-century compressors they replace — something you notice on a shaded Castle Hills street.

Inside a typical Castle Hills home
Most Castle Hills projects happen in a mid-century ranch — tap the rooms to see the honest fix and its published price range, or explore all five San Antonio house types.

Converted garage
The converted garage is the hottest room in the house — it was built for a car, not for people, and the ducts never reached it.
A single-zone head conditions the conversion independently, typically in a one-day install.

Specialist vs. generalist
Why Castle Hills homeowners choose a ductless specialist
Plenty of good HVAC companies install mini splits on the side. The structural difference with a specialist isn't effort — it's focus. Here's what that means in practice.

Our 1960s ranch has hot rooms at one end — can ductless help?

Often, yes — especially in stages. Start with the highest-pain zones, then retire the central system when it fails. We'll give you an honest read during the free estimate; if central replacement is the better answer for your house, we'll say so.
