The large 14,000-Btu EdgeStar Extreme Cool AP14001HS combines an air conditioner, dehumidifier, fan and heater into one unit. Reviewers say performance is great in any mode, recommending it for rooms between 400 and 525 square feet. The AP14001HS removes up to 85 pints of moisture per day, the most in our report. Its dual-hose design boosts air circulation, while the washable pre-filter and replaceable carbon filter remove extra particles from the air.
Powerful air conditioner with quiet fan. The EdgeStar Extreme Cool AP140001HS is an excellent pick "if you're looking for something with a little more style and that can provide year-round cooling or heating," says Mariette Mifflin, the appliances expert at About.com. Able to cool between 400 and 525 square feet, many owners say this 14,000-Btu air conditioner is ideal for larger spaces like living rooms. A built-in timer can be programmed for up to 24 hours, automatically adjusting the temperature between 61 and 77 degrees Fahrenheit. About 85 percent of owners recommend it, though a few say the heater doesn't work quite as well as the air conditioner.
Large and heavy. The AP14001HS is the largest portable air conditioner in our report -- weighing 75 pounds and standing almost 3 feet tall. Because it both cools and heats, however, many owners use this year-round and don't need to store it for part of the year. The self-evaporative system is very effective; in very humid climates some users say they still need to empty water occasionally or add a drain hose to the outside. The window kit can install with one or both hoses (experts recommend using two hoses for the best results), and the filtration system includes a washable pre-filter and replaceable carbon filter.
Multifunction appliance is a great value. The EdgeStar AP14001HS can run as an air conditioner, heater or dehumidifier, yet costs only slightly more than similar single-mode models. "With three functions, consumers find this a versatile and affordable unit," says Mifflin. She adds that "on the cooling side, this unit has a high 11.2 EER -- that's very good for efficiency." The AP14001HS has one of the highest energy ratings in our report. EdgeStar's warranty covers parts and labor for one year, and compressor parts only for three years. After the first 90 days, owners are responsible for the time and cost to ship the air conditioner for warranty service.
About.com's housewares and appliances expert, Mariette Mifflin, includes the EdgeStar Extreme Cool AP14001HS in her list of the best portable air conditioners. She picks the Extreme Cool because of its combination of style and function, recommending the unit for year-round use.
