What is a smart thermostat?
A smart thermostat is a Wi-Fi-enabled device that controls your home's heating, ventilation, and air conditioning (HVAC) system. Unlike traditional thermostats, it connects to the internet, allowing you to adjust the temperature remotely using a smartphone, tablet, or computer.
Some smart thermostats use sensors and learning algorithms to understand your habits, detect occupancy, and consider weather conditions to create efficient heating and cooling schedules. This helps improve comfort while reducing energy consumption and costs.
Many smart thermostats also offer additional features such as:
Remote temperature control via mobile apps
Integration with voice assistants like Amazon Alexa or Google Assistant
Learning your schedule to automate temperature adjustments
Geofencing to adjust settings based on your location
Energy usage reports and insights
Alerts for maintenance, such as filter changes or system issues
Compatibility with other smart home devices and platforms

Smart thermostat cost factors
Several factors can influence the cost of installing a smart thermostat:
Built-in voice assistant: All smart thermostats can use Wi-Fi, and most can connect to popular voice assistants like Amazon Alexa and Google Assistant. Some advanced models come with built-in voice assistants and cost between $50 to $100 more than those without voice control capabilities.
Multiple zones: Installing multiple thermostats or zoning systems can significantly increase costs, potentially reaching $2,000 to $12,500 for complex setups.
Wiring: Adding wiring to accommodate a smart thermostat can cost $90 to $140. The thermostat must be connected to both an electrical source and your HVAC system. Most modern thermostats require a C-wire, and you may have to install or replace wiring, depending on your system’s design and the condition.
Relocating a thermostat: Moving a thermostat to another part of your house can cost $65 to $450, depending on whether you need to install new wiring or cut and patch drywall.
Repairs: An HVAC repair costs $75 to $150 per hour or $190 to $480 for repairing a furnace thermostat.
