Programmable thermostats are more accurate and efficient than thermostats that contain mercury. With a programmable thermostat, you can program settings in advance so that you can control the temperature at different times of the day. You will never have to worry about remembering to adjust the settings manually. By scheduling your programmable thermostat to a higher or lower temperature based on your weekday work hours, you can save money on energy bills without sacrificing comfort. A Armor Heating & Air LLC technician will gladly walk you through how to use your programmable thermostat.
