“House by the river was always muggy. Dehumidifier and duct sealing fixed it. They drove out from Seguin and were honest about the schedule.”
A smart thermostat only saves money if it is wired and configured right for your system. We install and set them up across Castroville — and fix the ones a big-box install left half-working.

Smart-thermostat setup
A mis-wired or mis-configured thermostat can short-cycle your system, ignore your schedule, or fight your heat pump. We match the thermostat to your equipment and set it up properly for your Castroville home.
Repairs, upgrades, and smart-thermostat installs — flat-rate, quoted first.
Call (830) 587-5790Whether yours quit or you want to upgrade, here is what we handle in Castroville.
We install and configure smart thermostats, verify HVAC compatibility — especially with heat pumps and multi-stage systems — and set the schedule so it actually saves through the Medina County cooling season instead of just looking modern.
A thermostat that misreads temperature or will not hold a setpoint can be the stat itself, the wiring, or a control-board issue upstream. We diagnose which, rather than swapping the stat and hoping.
The number-one reason a DIY or big-box smart-thermostat install goes wrong is a missing C-wire or a heat-pump miswire. We sort the wiring and make it work with the system you actually have.
The 1840s and 1850s homes that make Castroville a landmark often carry undersized panels, knob-and-tube, and two-prong outlets. We modernize the electrical with real care, keep the historic character, and document it with a permit for insurance and resale.
| Service | Notes | Price |
|---|---|---|
| Thermostat replacement | Smart setup + HVAC compatibility check | $150–$400 |
All prices flat-rate, all-in, written and approved before work starts. No travel surcharge for Castroville.



From the historic Alsatian district along the Medina River to the homes just outside it, we reach Castroville on the extended run. A few of the areas:
“House by the river was always muggy. Dehumidifier and duct sealing fixed it. They drove out from Seguin and were honest about the schedule.”
“Our Alsatian home is a landmark and we were terrified of someone wrecking it. Moorhead modernized the wiring with real care, kept everything original-looking, and pulled the permit. Rare to find that respect.”
