Don't put your thermostat in these spots

The most important thing about thermostat placement is to avoid areas that experience temperature extremes, making your thermostat think that the room is a lot cooler or warmer than it actually is. After all, your thermostat is there to keep you comfortable.

Don't install your thermostat near doors that could let in drafts, in direct sunlight by windows or near a bathroom door that could frequently be warm and steamy. Also, the US Office of Energy Efficiency & Renewable Energy advises against putting lamps or TV sets near your thermostat since they release heat that could confuse the device's sensors. It's likely a good idea to keep your thermostat out of the kitchen for that reason, too.

Exterior walls are also a no-go because they are often cooler than other walls in the home. Any of these less-than-ideal spots for a thermostat could trick it into cooling or heating when it really doesn't need to, using up precious energy and money.

Some thermostats are put in rooms or hallways that are rarely used. This isn't a great idea either, because the thermostat won't be reading the temperature of the area you actually want to heat or cool. This can leave you sitting in a room that is uncomfortably warm or cold.

The best location to put your thermostat in your house

Put your thermostat on the interior wall of a highly-trafficked room for the best results. If you have a smart thermostat, be sure that it is unobstructed by doors, bookshelves or decorations so that its sensors can work properly. Also, make sure that your smart thermostat is in range of your Wi-Fi so that it can stay connected to your account.

As always, consult an HVAC professional if you have questions about your home's wiring. For smart thermostat installation basics, start here.
