Thermostat Service in San Marcos
Whether yours quit or you want to upgrade, here is what we handle in San Marcos.
Smart Thermostat Installation
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 Hays County cooling season instead of just looking modern.
Thermostat Not Reading Right
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.
Wiring and Compatibility
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.
Why San Marcos Homes in Particular
With Texas State driving a huge rental market, a lot of San Marcos houses have had maintenance put off for years. Filthy ductwork, filters nobody changed since the last lease, AC sized for a family but cooling a house packed with roommates. We get rentals back to honest working order and tell landlords the truth about what is worth fixing.
