Reviews show the Kenmore 70051 5,200-BTU air conditioner to be a solid and economical choice to cool a small room of 15-by-10-feet or less. Not only does it cost less than most ACs in its category, but it also exceeds the energy efficiency requirements for an Energy Star rating. This helps keep your energy bill down long after purchase. Owners say this model cools a small room efficiently and is fairly quiet, but many are bothered by the loud beeps that accompany adjustments in temperature and settings. Features such as a remote control and an energy-saving timer keep the 70051 on par with its higher-priced competition. Reviews conclude that the unit performs as well as other similarly sized models, although it doesn't aim airflow to the right very well.
Owners appreciate the ease of assembly and installation, but some find that the unit's black control panel and remote control make it difficult to see user options. One complains that the display screen is too bright, making it a less desirable choice for a bedroom. One alternative is the Frigidaire LRA074AT7 ($160), but its 6,500-BTU capacity makes it better for 150- to 250-square-foot rooms; experts caution that installing an air conditioner that's too big for your space can actually waste energy by forcing the unit to cycle on and off repeatedly.
ConsumerReports.org tests 43 window-mounted air conditioners and gives each one an overall score based on its ability to cool its advertised space while staying energy-efficient and keeping noise low. These AC units also receive a rating for categories such as brownout performance, ease of use and airflow direction. The Kenmore 70051 is included in this testing.
