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.

Designed to cool relatively small bedrooms or home spaces of up to 150 square feet, the 5000-BTU -- an unsurprising BTU rating for a small air conditioner -- Frigidaire FFRE0533S1 measures only roughly 16 inches wide and 12 inches long. It comes with a 4-way air deflection system and a dehumidification rate of up to 1.1 pints per hour.

At the time of writing, this compact window-mounted AC unit averaged a rating of 4.5 stars from a total of 7798 user reviews. Like several other units in this AC category, efficiency is apparently the name of the game for the FFRE0533S1, seeing that it scores a favorably-high 12.2 EER or energy efficiency ratio (Some of its contemporaries only have around 10-11 EERs) and a 37-dollar energy star annual cost, the latter of which could make it a reasonable choice for the budget-cautious. This small energy-efficient air conditioner also comes with a low-power startup (at least according to Amazon) and has a timer function, in case you don't want it running all night. Some users also loved its full-function remote control, which is obviously a nice touch, coming from a compact AC.

On the flip side, a few reviewers gave it dismal scores of only 1 or 2 stars, cautioning that this Frigidaire model may not be the best fit for light sleepers, with some users noting that it was among the noisiest ACs out there. Having said that, a few other users mentioned that, for its size, it gives off an acceptable amount of noise, so there are two sides of this coin.

With all that said, our comprehensive review crawler, which rummaged through 39041 reviews for small air conditioners, determined that the Frigidaire FFRE0533S1 nevertheless merits a spot in our list of the top 10 compact ACs.
