Considering this small window air conditioner's average rank of 90%, we believe that the Frigidaire FFRA051WAE is currently Alphachooser's best small window air conditioner 2021.

With its 9 stars over 1991 reviews, we rank this AmazonBasics 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.

Measuring a mere 12 inches long by 16 inches wide, the 4.5-star hOmeLabs AC-188 is a compact air conditioner with a 5000 BTU rating, which translates to a maximum cooling coverage of up to 150 square feet -- most of its 2234 reviewers have it running in one-bedroom or studio apartments that are within that range, with a couple of others using it to cool their RVs. Given its size, the AC-188 lacks a couple of perks that would otherwise be standard facets for mid-sized AC units, including a digital temperature readout (Its two physical knobs, as one satisfied reviewer puts it, could not be any simpler) and a full-function remote control.

On the other hand, this small window-mounted unit's unobtrusive size has its merits as well, including a relatively quiet ambient noise and, more importantly, for one particular user, the absence of an annoying ratting sound that's somewhat typical of larger ACs.

One pleased reviewer mentions that it's not as flimsy as a few other major-brand small ACs (most of which are also presented here at AlphaChooser), adding that its body does not feel that plastic-y . The same reviewer says that the AC-188 would be a perfect fit for a mid-sized studio apartment under northern climates , but cautioned that it only deflects air from left to right (no up-down deflection), which could be a problem for users who plan to install it onto a relatively low-rise window or AC slot. While some buyers call is a live-saver, though, the AC-188 does not please everyone (no air conditioner does), with several users protesting its operational noise.

At the end of the day, given its assortment of user reviews, our shopping algorithm, which sampled 28629 reviews for AC units under this category, concludes that the hOmeLabs AC-188 is an Alphachooser good choice and, accordingly, belongs to the top 10 small window ACs.
