Thermostats for Tecate homes, done by licensed San Diego County technicians. A new thermostat is only as smart as its install. We pull the old one, verify your system wiring (including the common wire that most DIY installs get wrong), mount the new unit, and walk through app setup, geofencing, scheduling, and HVAC-specific features so you actually use them..
Same-day service in Tecate on most weekdays. Morning slots book fastest during heat waves, call before 10 a.m. for best-same-day availability. After-hours emergency calls are answered by an on-call technician, not a dispatcher.

Tecate sits at 1,700 feet elevation at the Mexican border crossing along SR-188 with hot dry summers (95-105 degrees common), mild winters, and severe SDG&E PSPS exposure. Rural residential and small border-crossing commercial, with propane-to-heat-pump conversion as the dominant upgrade.. We account for local conditions in every job.

Ecobee Premium or Smart Thermostat Essential for homes with multiple hot/cold rooms (remote sensors are the killer feature). Nest Learning for households that want it to figure out schedules on its own. Honeywell T10 if you need real multi-zone control. We'll recommend based on your home.
