What Makes a Thermostat “Smart”?

Smart thermostats connect to Wi-Fi, so you can adjust them from your phone, and most learn your schedule or use your phone’s location to set back temperatures when you’re away. Many report energy use, send maintenance reminders such as filter changes, and work with remote room sensors and voice assistants.

Getting Real Savings

A smart thermostat saves energy by not heating or cooling an empty house, and by shifting cooling away from expensive peak hours. The savings depend on setup: schedules that fit your routine, setbacks that are big enough to matter, and, for heat pumps, settings that keep expensive backup heat from running when it isn’t needed. We set those up at installation and show you how to adjust them.

Smart Thermostats in San Jose

Local reasons a smart thermostat pays off.

  • Time-of-use rates

    PG&E time-of-use plans make late afternoon and evening the priciest time to run AC.

Smart Thermostat Installation FAQs

How is a smart thermostat installed?

Turn off power to the HVAC system, label and disconnect the old thermostat's wires, mount the new base, connect the wires (adding a C-wire if needed), restore power and configure it in the app. Mistakes can damage equipment, so we recommend professional installation for heat pumps and multi-stage systems.

How much does smart thermostat installation cost in San Jose?

Typically $200 to $500 installed, depending on the thermostat and wiring.

Do I need an electrician to install a smart thermostat?

No. Thermostats run on low voltage; an HVAC technician is the right person, especially if the system needs a C-wire or special configuration.

Can I replace an old thermostat with a smart one?

Usually, yes. Very old two-wire or line-voltage systems may need a different solution.

How do I know if my system is compatible?

Check the wires at your current thermostat and the manufacturer's compatibility tool, or let us check. Line-voltage baseboard heaters need special thermostats.
