Considering this 12000 BTU window air conditioner's aggregate ranking of 90%, we believe that the Midea MAW12V1QWT is currently Alphachooser's best 12000 BTU window air conditioner 2021. Furthermore, we think that our sample of 9070 reviews from multiple sources gives us a high confidence level (more on confidence levels) that justifies labelling it a "no-brainer best choice."

The LW1216ER from LG is a 12000 BTU window AC that's gathered praises for being "surprisingly quiet" (but with its 52dBA max noise rating, this really isn't surprising for us here at AlphaChooser). Our review crawler has so far gone through 5340 reviews for this window-mounted air conditioner and found that it has gotten a combined rating of 4.5 stars.

While it's generally known that newer air conditioners are much more efficient than their predecessors, this particular LG model takes it to another level with an energy efficiency ratio of 12.1, which is just 0.2 shy of the highest value we've seen across all air conditioners. It's probably due to this highly-competitive energy efficiency aspect that some customers who've bought one unit have chosen to buy more to replace all the air conditioners in their respective homes, seeing that the cost of the LG LW1216ER "saves more money over the cost to operate an older model" .

Some people didn't seem to like the fact that this 12000 BTU window energy-efficient air conditioner defaults to the energy saver mode every time it's switched on, but this very same fact was also a pro for other consumers. Also, this AC apparently isn't the easiest to install, mainly due to the product's weight and the diagrams on the manual being a bit too small. As such, solo homeowners should expect needing company when setting up this AC -- or you can go the other route suggested by many buyers and get Amazon's installation services for yourself.

This energy-efficient air conditioner is Alphachooser's second best 12000 BTU window air conditioner 2021, according to our algorithm that has scanned through a total of 30808 reviews for all the models in the 12000 BTU window AC sub-category.

The Koldfront WAC12001W appears to have managed being a 12000 BTU window AC that is also reasonably-quiet, seeing the number of times that it has been praised on reviews for this said feat. Many reviewers also seem to have thought of it as a well-engineered model with thoughtful features. Used both in wall- and window-mounted setups, this reportedly handles both its cooling and heating functions adequately. Buyers also appreciate that it already comes with window-mounting equipment.

This 12000 BTU air conditioner has an energy efficiency ratio of 10.9, which is a rather-average spec (if this is an important facet for you, we have a list of the best energy-efficient air conditioners on AlphaChooser that you can check out). However, although the 99-dollar Energy Star annual cost figure affixed to this unit may be slightly-unsettling for those who are conscious about their electricity bills, most consumers have reported feeling that the price they pay to power this unit is within the bounds of what is (Q))reasonable." One pleased customer has said that he's used this AC to cool an entire two-bedroom unit, and that it does the job without burning a lot of power .

Most of the complaints we've seen for this air conditioner seem to be about remotes that were either not functioning or whose battery slots didn't close properly. Note, however, that these make up a very small portion of its 1388 total customer reviews, and that it doesn't have anything to do with this AC's cooling ability. Also, this is a 220V unit, so expect having to work on wiring to accommodate it.

At this point, it's safe to say that this AC has left most of its customers pleased, which makes its 4.5-star rating and position as an Alphachooser interesting choice not surprising at all.

Most reviewers of the LG LW1216HR window-mounted air conditioner (it has total reviews so far) have nothing but praises for how this fellow performs. Many say that it cools well and that it remains quiet while doing so. With a relatively-high energy efficiency ratio of 11.3, it has been associated with other energy-efficient air conditioners here on AlphaChooser. One reviewer even said that this LG AC cut her summer electric bill in half .

Technology-challenged users will find it nice to know that many reviewers have noted that this 12000 BTU window air conditioner is very easy to operate with its remote control. It works quickly as a heater, with some reviewers reporting reaching "toasty warm" levels within a few minutes.

While its ratings aren't perfect, the portion that consists of negative reviews is minuscule compared to the approving majority. Looking at them, it seems like most of the dissatisfaction stems from inefficiencies in shipping that has unfortunately caused damages on a small number of ACs. Only one negative review appeared to have something to do with the product itself (as of now, at least), with the said review expressing dislike that this energy-efficient 12000 BTU window air conditioner didn't come with a standard plug, which should be easily resolved by purchasing an adapter.
