Thermostat selection plays a big role in the function of your home’s HVAC systems. Homeowners have many options to choose from when selecting a thermostat—from traditional to programmable, smart thermostats and more. To begin the selection process, homeowners should identify what type of HVAC system they have. Once you’ve identified what type of heating/cooling system you have, and therefore what type of thermostat you need, select a thermostat with the functionality that will work best for you.
