A smart thermostat is a Wi-Fi-connected thermostat that controls heating and cooling equipment through a phone app, schedules, and automation such as occupancy sensing or learning routines. Many models report runtime and filter reminders, and most need a steady power supply, usually a common wire (C-wire), plus correct wiring for the furnace, heat pump, or dual-fuel system.
Why it matters to you
Older Fraser Valley furnaces and heat pumps often lack a C-wire, which causes intermittent power or battery drain on newer thermostats. Heat pump systems also need the thermostat set up correctly so backup heat is not used more than necessary.
Practical guidance
Confirm the thermostat is compatible with your exact equipment, including heat pump or dual-fuel staging, before buying. Mount it away from drafts, sunlight, and supply registers so it reads the room accurately.
