Thermostat Location: Is Mine In The Right Place?

While your thermostat works wonders to set the desired temperatures in your rooms, it can be fooled if the air around it is colder or warmer than the air in the rest of your home. This may cause it to set incorrect temperatures. So, you’ll need to make sure your thermostat’s location is optimal for operation.

Where Should My Thermostat's Location Be?

Your thermostat sets your home’s temperature based on its reading of the air directly around it. If you place your thermostat near where the air is colder or warmer than the rest of your home, such as by a window, vent, ceiling fan, or in direct sunlight, it may be tricked into setting a false temperature.

How to check if your thermostat location is ideal

  • Look around the area your thermostat is in to see if there's anything that could be causing an inaccurate temperature reading. Direct sunlight, nearby vents, drafty windows, or fans can make the thermostat think that your house is warmer or colder than it actually is.

    Likewise, being too far removed from the normal circulation of air in the home can also cause a bad reading. Make sure your thermostat isn't in a corner or blocked by anything.

  • If your thermostat is near a window, try blocking the sunlight with blinds or even a sheet to see if that changes how your thermostat controls the temperature throughout the day. You can also keep a log of days that your HVAC system was cooling or heating too much and comparing the log to the weather on those days. If your house gets too cold on sunny days, that's a sign that your thermostat is in a bad location.

  • Place a thermometer in an area of your home that is away from any potential environmental factors (sunlight, vents, fans, drafty areas). Leave it in the same location for a few days. Check the temperature periodically and compare it to the temperature reading on your thermostat. If there's more than a couple degrees of difference, then your thermostat might be getting a bag reading.

  • Pull your thermostat away from the wall and look at the wiring. Check to see if the thermostat is sealed where the low voltage wires come into the back of the thermostat. The wall it is mounted on may have an internal draft giving the thermostat a false sense of the actual room temperature.

    CAUTION: Be careful not to touch the metal part of the wiring directly. When in doubt, turn off the circuit breaker to ensure that there is no power to your thermostat.

What To Do If Your Thermostat Location Is Bad?

If your thermostat location is bad, but you’d like to minimize the difference in temperature in the air around it, keep any windows or vents closed, ceiling fans turned off, and shades drawn to block out sunlight.

If these methods don’t do the trick, there may be something else going on that will require help from a professional. You can reach out to one of our Remote Assist experts for a virtual diagnosis!
