A mix of house ages

78681 has a mixed housing stock: the typical home was built around 1998, with 54% before 2000. That means plenty of additions, sunrooms and garage conversions that the original system doesn't cover well.

Ductless is the clean fix for those rooms: no new ducts, no attic work, one wall penetration.

Heat and cool from the same unit

About 67% of homes in 78681 heat with gas. A mini split doesn't replace that furnace; it adds year-round comfort to the rooms the furnace and AC don't reach, with heating built in for cold snaps.

Every unit we install is a heat pump, so the room you add it to stays comfortable in January too.

Owner-occupied streets

About 75% of occupied homes in 78681 are owner-occupied. Owners tend to fix the problem room for good instead of pushing a window unit into it every May. A mini split is quiet, permanent and works on its own thermostat.

What it costs here

The median home value in 78681 is about $460,000. The install price doesn't move with it: Every mini split is $2,000 installed, however many you need.
