Short answer: yes — typically 8–12% on heating and cooling for households that actually use the scheduling features. But we've also installed smart thermostats that saved their owners nothing, because the settings never changed from "hold at 72." Here's the honest breakdown.
Where the savings come from
Not from magic — from three boring features: schedules that set back temperatures while you sleep and work, geofencing that eases off when the house is empty, and runtime reports that reveal problems (like a system running 40% longer than last July) before they become repairs.
Remote sensors: the underrated feature
For two-story homes and houses with a cold office or hot bedroom, wireless sensors are the real win. Instead of trusting one hallway thermostat, the system averages the rooms you actually occupy — or follows you from day to night. This alone fixes more comfort complaints than any equipment upgrade.
When it is not worth it
- You already program a schedule on your current thermostat and stick to it — savings will be minimal.
- Your system is 15+ years old and struggling — put the money toward the replacement fund instead.
- You have a heat pump with backup heat and aggressive setbacks — deep setbacks can trigger expensive auxiliary heat. Smart recovery settings fix this, but they must be configured correctly.
Installation notes from our technicians
Most installs take under an hour, but older homes sometimes lack the C-wire smart thermostats need for power. We verify wiring before quoting — a $25 adapter usually solves it, and we'll tell you upfront rather than mid-install. Every install includes Wi-Fi setup, schedule programming, and a walkthrough of the app.
