The 5 Best Small Window Air Conditioners April, 2018 (And 2 Others)

Considering this small window air conditioner's average rank of 82%, we believe that the Frigidaire FFRA0511R1 is currently the best small window air conditioner 2018. Furthermore, we think that our sample of 2648 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."

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 stars from a total of 428 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 4627 reviews for small air conditioners, determined that the Frigidaire FFRE0533S1 nevertheless merits a spot in our list of the top 5 compact ACs.

Measuring only 16 inches wide (most regularly-sized air conditioners measure more than 20 inches wide), the Frigidaire FFRE0533Q1 is a compact window-mounted air conditioner for the budget-cautious or those who simply need to cool a small space at home -- it is meant for rooms of up to 150 square feet, with its 5000 BTU.

Most positive reviews (Our review crawler scanned a total of 374 reviews for this particular model at the time of writing) for this small air conditioner mention its appreciable energy-saving features, one of which its apparently-prompt Eco Mode, which essentially enables it to shut itself off automatically when the desired temperature level is reached and likewise turn itself back on to reach a certain temperature. It also reminds us of a few other small energy-efficient air conditioners with its favorably-high 11.2 energy efficiency ratio (EER) and rather budget-friendly 40-dollar Energy Star annual cost.

Some users also noted the convenience of its full-function remote control, a facet that's obviously nice to have on a compact AC, despite being often overlooked when coming from much-larger units. Sadly, like a few other ACs of its kind, the 4-star FFRE0533Q1 suffered several negative reviews for its loud operation -- at least that's what some dissatisfied buyers say. That being said, the noise complaints range from makes a bit of noise when you are sitting near it, which is normal for most ACs, to extremely loud, so the verdict for this particular issue is still up in the air.

Knowing that our shopping algorithm crawled though a total of 4627 reviews for small window-mounted air conditioners, though, one verdict is for sure: The Frigidaire FFRE0533Q1 is among the top 5 small air conditioners on the market.

Frigidaire's FRA054XT7, a small 16-inch-wide window model, has an energy-efficiency rating (EER) of 10.7 and features a 24-hour programmable on/off timer that allows you to turn your unit on or off on set times.

The General Electric AEY05LV is a small window air conditioner obviously designed for small bedrooms and makeshift home office spaces. Unsurprisingly, for a small window-mounted air conditioner, its BTU rating caps off at 5000 BTU, while conventionally-sized ACs have at least 8000 BTU ratings. This means that this roughly-16-inch-wide model is designed to cool areas of up to 150 square feet only -- with two cooling/fan speeds to choose from. It also comes with what GE calls an EZ Mount Window Kit.

As of this write-up, this (rating temporarily unavailable)-star unit had reviews under its belt, with much of the positive feedback revolving around its ability to cool its promised coverage area, consequently making several homeowners love it for its cooling capability alone. The GE AEY05LV is also apparently an energy-efficient small window air conditioner, boasting a relatively-high 11.2 EER (Energy Efficiency Ratio) with a $41 Energy Star annual cost that's pretty much that ballpark figure for AC units of its size. A landlord, who apparently experiences tons of AC issues (as landlords often do) even recommends this unit for being, in his words, surprisingly efficient -- though efficiency and a compact form factor don't make that so surprising of a combination. Regrettably, some buyers were not so amused, complaining that the AEY05LV is a pretty loud unit, with one saying that it was practically like going to bed with a chainsaw roaring nearby. Removing the filter for cleaning also proved to be a challenge for some buyers.

In the end, however, our shopping algorithm, which scoured through a total of 4627 reviews for small window-mounted AC units, determined that the GE AEY05LV makes for a solid choice for those eyeing a small through-the-window air conditioner, especially since it joins our top 5 list in this AC category.
