For maximum accuracy, thermostats should be placed in the center of the home, away from air vents, plumbing pipes and exterior doors.
Avoid placing items like lamps and televisions near your thermostat, which can cause the HVAC to run longer than necessary. Avoid installing thermostats in rooms that tend to feel warmer or colder than the rest of the home. Do not place furniture in front of the thermostat, which can block air flow and result in inaccurate readings.
