Consumer Reports recommends that you match the features on a model to the needs you have. Here's our take on some of the specifications and features that are commonly available on air conditioner models like the ESA412K.

Btu/hr.:

The unit's cooling capacity, as supplied by the manufacturer (and as certified by the Association of Home Appliance Manufacturers, AHAM, unless otherwise noted in the Recommendations & Notes). Capacities range from 5,000 British thermal units per hour (enough for a modest-sized bedroom) up to 12,500 Btu/hr. (adequate for a large, sun-drenched room or even two interconnected rooms).

EER:

The energy-efficiency rating, as supplied by the manufacturer (and as certified by the Association of Home Appliance Manufacturers, AHAM, unless otherwise noted in the Recommendations & Notes). The higher a unit's EER, the lower its operating cost compared with other models of its size.

Min window width (in.):

The minimum and maximum window-widths into which the air conditioner will fit. If your window opening is narrower than the minimum width, the air conditioner will not fit. If your window opening is wider than the maximum width, the side panels will not cover the entire opening.
