If you have tall, narrow window openings such as casement or slider-type windows or you need to install your air conditioner through the wall, owners enthusiastically recommend the Frigidaire FRA103KT1. It costs a lot more than a regular-shaped window AC like the well-regarded LRA107BU1 (*Est. $280), but the FRA103KT1 is one of the few units manufactured in this narrow shape. At just 14.2 inches wide, it can fit between wall studs, too.
Owners report that the FRA103KT1 does a great job cooling the advertised 450 square feet. Several say it can cool an even larger area, especially if the dwelling is well insulated. It comes with most of the same features as the LRA107BU1 -- including an automatic thermostat, remote control, 24-hour timer and energy-saving sleep mode that gradually increases the temperature as you sleep -- but isn't Energy Star-rated, so it will use more electricity.
User reviews at Amazon.com, Walmart.com and Overstock.com provide the best feedback on the Frigidaire FRA103KT1.
With about a dozen customers posting reviews, the Frigidaire FRA103KT1 earns 4.6 out of 5 stars here. Owners say it does a great job cooling the advertised space and can handle an even bigger room, and it's fairly quiet. The remote control and energy-saver setting earn specific praise. A couple of owners report installing it through the wall.
