Most people don't know that the placement of the thermostat in their home matters!
Too close to the heating/cooling vents and your thermostat may cut off too quickly.
If it is placed too far away the system may run for too long.
False readings can occur in both situations.
You may also see a higher energy bill and a unhappy homeowner!
Double check that your thermostat is located on an interior wall and mounted 52-60 inches above the floor.
Away from air vents, doors, windows, and skylights.
