How we repair your Thermostat
A thermostat controls heating and cooling equipment by reading room temperature and sending signals to the furnace, boiler, heat pump or air conditioner. A thermostat typically uses a fan, filters or media, a humidistat or sensors, and an electronic control, plus a compressor on dehumidifiers. A technician checks airflow, sensors and controls, filters and drains, and any refrigeration or wiring involved.
