Frequently Asked Smart Thermostat Questions
A smart thermostat is a Wi-Fi-enabled device that automatically adjusts your home’s heating and cooling settings for optimal comfort and energy efficiency. These advanced thermostats are designed to learn your habits, help lower your utility bills, and improve system performance—all while giving you more control over your indoor environment.
ENERGY STAR Certified for Real Energy Savings
Smart thermostats that carry the ENERGY STAR label are independently certified using real-world data. That means they’ve proven to help reduce energy use without sacrificing comfort.
Smart Features That Make a Difference
- Convenience: Many smart thermostats can learn your preferences and create a custom schedule to save energy when you’re asleep or away. With geofencing, the thermostat knows when you’re heading home and adjusts the temperature accordingly.
- Remote Control: With Wi-Fi connectivity, you can adjust your heating and cooling settings anytime, anywhere—from your smartphone, tablet, or computer.
- Energy Insights: These thermostats provide real-time data on your system’s energy use, helping you track patterns and make smarter energy decisions.
- Automatic Updates: Regular software updates ensure your smart thermostat uses the latest energy-saving features and technologies.
One of the biggest advantages of smart thermostats is their ability to save money through precise temperature management. Unlike traditional thermostats that require manual adjustments—and often lead to overheating or overcooling—smart thermostats learn your daily routines and make automatic changes to maintain consistent comfort. By optimizing heating and cooling cycles based on occupancy patterns, they help reduce energy waste and lower utility bills over time.
