Here Are The Top 10 Best Small Window Air Conditioners 2021

Considering this small window air conditioner's average rank of 90%, we believe that the Midea MAW05M1BWT is currently Alphachooser's best small window air conditioner 2021. Furthermore, we think that our sample of 9230 reviews across multiple 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 6630 reviews, we rank this Frigidaire 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 4.5-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 8217 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 40614 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.

Measuring a mere 12 inches long by 16 inches wide, the (rating temporarily unavailable)-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 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 40614 reviews for AC units under this category, concludes that the hOmeLabs AC-188 is is not quite a head-turning small air conditioner, at least versus the better-reviewed ones at the top of this list.
