Breaking it down

Performance

It's the strong, sort-of-silent type. Expert reviews and user feedback indicate that the LG LW1216ER does a great job cooling down spaces up to 550 square feet. At ConsumerReports.org, it gets an Excellent rating for comfort, a Very Good for noise on low, and a Good for noise on high, putting it in the top echelon for all three factors among all machines tested in its size range. Some of ConsumerReport.org's testing is detailed by Mary H.J. Farrell in an article that is free to the public. In that overview, Farrell notes that the LW1216ER is one of the top performing large-sized air conditioners for 2017. At TheSweethome.com, Liam McCabe tests the LW1216ER's smaller sibling, the LG LW8016ER (Est. $240), and finds the LG's pitch is somewhat less annoying than other units they tested. User feedback, while limited, is fairly positive, too, including recommendations from 90 percent of the owners whose reviews can be seen at HomeDepot.com

Ease of use

The slide out chassis is a plus. LG's smaller-sized units get beat up a little as being challenging to install. That's why it's a pretty good thing that the LW1216ER has a slide in chassis (something those models lack) to make the task of getting this 81 pound unit in place quite a bit less back breaking -- and less dangerous. ConsumerReports.org goes so far as to say that it is easy to install, and the limited user feedback we see usually -- though not always -- agrees. Operation is relatively straightforward, with a basic remote and simple digital controls

Durability

Standard, one-year warranty. The warranty on the LG LW1216ER is as basic as its operation: one-year, with no extended warranty on the sealed system. We saw few complaints of durability issues, aside from a few units that arrived damaged in shipping, but LG's customer service comes in for some knocks on occasion, especially if you buy from an unauthorized dealer. If you buy from an authorized retail outlet, you may be better off appealing to their customer service departments. Otherwise, be prepared to be persistent, patient and polite.
