Here Are The Top 10 Best Small Window Air Conditioners 2020

Considering this small window air conditioner's average rank of 88%, we believe that the Frigidaire FFRA051WAE is currently Alphachooser's best small window air conditioner 2020. Furthermore, we think that our sample of 830 reviews from our sources gives us a high confidence level (more on confidence levels) that pushes us to call it a "no-brainer best choice."

With its 4.5 stars over 626 reviews, we rank this Whirlpool model second best small window air conditioner. * These choices are based on a full analysis of hundreds of small window air conditioner reviews from multiple sources.

Designed to cool relatively small bedrooms of up to 150 square feet, the compact Frigidaire FFRA0511R1 comes with a 5000 BTU rating, a 1.1-pint-per-hour dehumidification rate, and a basic two-way air deflection system. Frigidaire also markets it as having a low-voltage start-up and a quiet operation, which are not very surprising facets in the world of small air conditioners. Also, it comes with a respectable energy efficiency ratio (EER) of 11.1 and a $41 annual cost.

Some of its happiest reviewers go as far as saying that this 4-star low-profile AC is a great little unit, praising it for cooling a small home space as advertised. Several other users also mention its ease of installation, although it's probably safe to assume that one, given its 15-inch-only width. Some people also commended it for apparently not being too loud -- a window-mounted air condition that's small and noisy is a obviously a big no-no.

Sadly, not all of its 10401 reviews were positive, with some cynical users complaining that this unit stopped working after just a couple of months and that it only blows cold air when turned up to the maximum setting. Speaking of settings, the FFRA0511R1 does not have a thermostat that displays the specific temperature. Instead, it comes with a 7-level cooling knob, 7 being the coolest setting. It also does away with a remote control, so you pretty much have to get up to adjust the temperature setting, although this is a rather forgivable setback, coming from a window AC tailored to tiny bedrooms and makeshift home office spaces.

To rehash, after our review crawler scoured a total of 22211 reviews for ACs in this particular category, we can confidently say that the Frigidaire FFRA0511R1 deserves a spot in our hotlist of the top 10 small ACs on the market.

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 3.5 stars from a total of 2618 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 22211 reviews for small air conditioners, determined that the Frigidaire FFRE0533S1 nevertheless merits a spot in our list of the top 10 compact ACs.
