DIY vs. Call a Pro
Most smart thermostats are designed for DIY installation. Turn off HVAC power, label existing wires, connect to matching terminals on new thermostat, and follow the app setup. Check if your system has a C-wire (common wire) — some smart thermostats need one.
Call a professional when:
Call a professional if your system lacks a C-wire and the thermostat requires one, if you have a multi-zone system, or if your wiring doesn't match standard configurations.
