If your thermostat is in direct sunlight, you run the risk of getting false readings. The thermostat records the temperature of your home (specifically the room in which it is placed) and uses that information to judge whether the heating and cooling system needs to kick on. If the thermostat is located near a skylight and heated by direct sunlight, it will register that the room is warmer than it actually feels, causing your air conditioner to kick on when it isn’t needed. These “ghost readings” cause your heating and cooling system to waste a ton of energy by cycling on and off unnecessarily.

Above Air Vents

Your thermostat is supposed to be able to accurately represent the temperature feel in your home. When the thermostat placement is above or near an air vent, the temperature readings get skewed because the thermostat is the first thing to get hit with incoming air. If the heater is on, the thermostat “thinks” the room is warmer than it is, and if the air conditioner is running, the thermostat cools down before your home does.

Near The Kitchen

Of all the places in your home, your kitchen probably gets the warmest without the help of your heater. A thermostat placed in the kitchen often reads that the home is far warmer than it truly is, causing the air conditioner to turn on when you don’t need it. But because your kitchen isn’t constantly warm, it poses a big problem for your thermostat. The fluctuations in temperature confuse your thermostat and prevent it from getting an accurate reading.

Near Doors And Windows

Drafty windows cool down the areas around them, so if your thermostat is in the general vicinity, it’ll take readings that show the room as being much cooler than it actually feels. Since doors are constantly being opened and closed, a thermostat placed near a door would naturally be exposed to more outside air than the rest of the house. Depending on the season, this causes your air conditioner or heater to cycle on and off without ever achieving a comfortable temperature.

Ideal Thermostat Placement

The best place for your thermostat is on an interior wall. Ideally, it should be placed toward the center of your home. You should also take into consideration the rooms you and your family members use most frequently. That way, you’ll be certain the rooms in which you spend the most time are the most comfortable for the ones you love.
