Kenmore 75050 (5,000 BTU)

The Kenmore 75050 5,000-BTU air conditioner is a no-frills, budget window unit suitable for a small room of about 150 square feet. Reviewers say it cools very well, but owners are split on the noise factor. Some say it's quiet while others disagree with comments such as "HORRIBLE noise!" The Kenmore 75050 is not Energy Star-rated, which means it'll cost more to run than most air conditioners available. We read numerous complaints about durability; some owners posting to Sears.com say their units broke after the first year, others after three months or less. If you're looking for an energy-efficient air conditioner for your small room and are willing to pay a little more, reviews recommend the still-economical 5,200-BTU Kenmore 70051 (*Est. $160), which will cool the same size room, and offers features not included on the Kenmore 75050 such as a remote control and digital controls.
