FAQ
Which smart thermostat should I buy?
Popular choices include Nest Learning Thermostat, Ecobee SmartThermostat, and Honeywell Home T-series. Ecobee includes room sensors for better multi-room comfort. Check compatibility with your HVAC system before buying.
Do smart thermostats work with all HVAC systems?
Most work with standard 24V systems (furnaces, central AC, heat pumps). High-voltage systems (baseboard heaters) need specific models. Check for a "C-wire" in your current thermostat - some smart thermostats need it, though many include adapters.
Will I save if I'm home all day?
Yes, but less than someone who's away regularly. You'll still benefit from learning algorithms, automatic night setbacks, energy reports, and avoiding forgotten adjustments. Expect 5-8% savings instead of 10-15%.
