Editor's Pick: If your room feels stuffy in summer and chilly in winter, a wall-mounted AC unit can handle it all year round. With 12,000 BTUs of cooling and heating power, it's more than enough for a small living room or master bedroom. WiFi control lets you turn it on from your phone ahead of time, so the temperature is just right when you get home. With an 18.2 SEER2 energy efficiency rating, it's quite efficient and will help save on electricity even with extended use. The white body is sleek and simple, and mounting it on the wall saves floor space.
