The control that tells your system when to heat or cool. Programmable and smart models can cut energy use significantly.
Why this matters for your home
The thermostat is the control center that senses room temperature and tells your system when to run. Options range from basic manual models to programmable and smart thermostats that adjust automatically around your schedule.
Placement and setup matter more than people expect — a thermostat on a drafty hall or sun-struck wall misreads the home and runs the system unnecessarily. We confirm it's located and configured correctly, and matched to staged or variable-speed equipment, so it controls comfort accurately.
