An improperly placed thermostat can have a significant impact on your heating and cooling usage and costs. If the thermostat is located in direct sunlight, it will not get a true reading of the actual temperature in your home.
In the winter, your home could be cooler if your thermostat is warmed by the sunlight and turns off the heating system prematurely. In the summer, on the other hand, your cooling system will run longer than necessary if the thermostat is warmed by the sun. You wouldn't think that improper thermostat placement would happen that much since they are usually installed by heating and cooling specialists, but I have seen it in a number of homes.
Check your thermostat placement if you are experiencing inaccurate temperature readings or if you suspect your system is turning on or off at the wrong time.
