There is a good chance that your thermostat needs to be replaced. Many homes, particularly those in the Midwest still use mercury thermostats. These thermostats are illegal in many states and can be dangerous to your health and the environment. Many thermostats now mimic the old-fashioned, round design of older mercury-filled thermostats but do not contain mercury.
Another important factor to consider is the cost of energy. Many thermostats can be programmed to reduce heating costs by up to a certain percentage. Your thermostat will not be neglected and your bills won’t go up with the preprogrammed settings. Heating and cooling are too costly to ignore or forget about. A thermostat that saves 33 percent or more energy may be the best option for you. Make sure your thermostat is EnergyStar-listed.
You may need a thermostat that is more accurate than the one you have. A thermostat should be accurate within one to two degrees. A thermostat is meant to control the temperature of your heating and air conditioning systems so that you don't have any guesses. Most thermostats are not worth the effort. Many are outdated and can easily be upgraded to one with an LCD or touchscreen display. Modern Vivint thermostat models are available in blue and green, as well as soft-touch buttons.
This gives them a higher design quality. Lighting is another reason to upgrade. Backlighting is a common feature on thermostats. This allows you to see your temperature and adjust settings in darkened rooms.
If parts of your home are perfectly comfortable, while other spots are definitely not, consider zone control with a new thermostat and sensors to access the temperatures from different portions of the house and signal certain parts to be heated or cooled.
This way, your thermostat will not just work to direct warmth or cooling power to balance the area directly surrounding it.
