For optimal cooling convenience, the best smart air conditioners use Wi-Fi — and some even have voice control through Alexa and Google Home. That said, these features alone aren't enough to earn the title of "best air conditioner." You also need to consider how powerful it is, the intended square footage, and the reviews.
BTUs (or British thermal units) are used to measure heat — specifically the energy needed to raise 1 pound of water 1 degree Fahrenheit. When referring to air conditioners, BTUs indicate how quickly a unit can cool a room within a single hour. However, keep in mind that more isn't necessarily better, especially for smaller spaces; more power uses more energy, which can quickly get expensive if you don't need it.
For the most part, a unit's BTUs should go hand in hand with its intended square footage. For example, a 150-square-foot room needs around 5,000 BTUs, while a 550 square-foot-room requires around 12,000 BTUs. (For your convenience, both stats are listed for the below products.)
Last but not least, always check the ratings and reviews. Smart products are definitely convenient — but the more complicated the components, the greater the likelihood that something could malfunction. So before making a purchase, consider the opinions of former buyers to save yourself some headaches down the line.
These smart ACs are some of the most highly rated, and they let you control your home's temperature from anywhere.
