Look at Voltage Requirements
Most homes use either low-voltage systems or high-voltage systems. Low voltage systems are the most common for residential HVAC units. If your system is powered by low voltage (usually 24V), you'll need a thermostat that works with low voltage systems.
On average, most thermostats last about 10 years, depending on the model, usage, and proper maintenance. However, many people decide to replace their unit sooner to take advantage of new energy-saving technologies.
It's always a good idea to consult a professional to be sure you install your smart thermostat correctly. The potential to do something wrong could damage your home or lead to an electrical shock.
