Here Are The Top 10 Best Small Window Air Conditioners 2021
While a small window air conditioner might not provide as much power as bigger units, it is sufficient for one room, small- to medium-sized, of around 200 square feet. These 5000 BTU models usually no more than 16-inch wide or less, down to 14-inch wide for the narrowest units, should be sufficient enough for small rooms. However, if height is your concern (low profile), you should check out our best low-profile window air conditioner list (where all models are under 12.5-inch high), but if width is what matters, check out our list of the best narrow casement window air conditioners.
Back to this list: It includes some small air conditioners that have a standalone dehumidifier and a 24-hour on/off timer to save electricity. Some even have a remote control with a built-in thermostat display that gives you a temperature reading wherever you are in the room -- a feature normally associated with higher-priced air conditioners.
All of the small air conditioners listed here are window-mounted models and designed for narrow windows. *Widths, on this list, are rounded for readability. The quietest models revolve around the 49-50dB mark.
