Millions of homeowners have installed smart thermostats in recent years, and for good reason: they offer a perfect blend of convenience and energy efficiency. But is upgrading to a smart thermostat worth the investment? HVAC.com explores the costs of installing a smart thermostat and the factors that influence pricing.

Factors that Determine the Cost of a Smart Thermostat

Brand and Model. There’s no shortage of brands and models to choose from when shopping for a smart thermostat, and each comes with varying features, reputation, and quality, all of which can influence their price points. A few of the most popular models include the ecobee Smart Thermostat Premium, the Amazon Smart Thermostat, the Honeywell Home T9 Smart Thermostat, the Google Nest Learning Thermostat, and the Sensi Touch 2.
Features and Functionality. Most smart thermostats come with standard features such as Wi-Fi connectivity, energy reporting, learning capabilities, and the ability to pre-set the temperature based on your preferences. More advanced features such as geofencing, voice control, integration with smart home systems, and temperature sensors for temperature control in individual rooms can increase the costs.
Installation. If you’re handy and experienced with basic electrical knowledge, you can save money by installing the smart thermostat yourself. Expect to pay between $100 and $150 to hire a professional for installation, with the costs going up if the installation has a higher degree of difficulty which might include adding a C-wire.
Energy-Saving Certifications. Models with energy-efficient ratings or certifications from agencies such as ENERGY STAR may carry a premium, but they can offer savings on energy bills over time. To meet ENERGY STAR certification, all smart thermostats must have the capability to enter a low-power standby mode when inactive for increased energy savings.
User Interface and Design. Sleek, user-friendly designs often come at a higher price, as they appeal to consumers seeking aesthetics alongside functionality and convenience. Larger, high-resolution displays can also increase the price.
Seasonal Discounts and Promotions. Prices may fluctuate based on sales events or manufacturer promotions, potentially lowering the cost during specific times of the year.
Rebates and Discounts. Some utility companies may offer discounts or rebates when you install an ENERGY STAR-certified smart thermostat.
Compatibility with Your HVAC System. The type of HVAC system can influence the price of a new smart thermostat, as some thermostats aren’t compatible with certain units. Selecting a thermostat compatible with your current system can affect costs based on its features.
