Bottom line

The 12,000-Btu NewAir AC-12000E is ideal for medium to large rooms, with reviews saying it cools quickly and efficiently. "It's a powerful air conditioner and easy to install," says one owner at Maintenance is low thanks to its self-evaporative system, removing the need to drain water manually. Most appreciate its solid, compact design; though it's louder than most at this size, the noise isn't a deal breaker for the majority of users.


Cools rooms quickly. Reviews say the NewAir AC-12000E is a powerful air conditioner, able to cool a hot room to a comfortable 70 degrees Fahrenheit in about two hours. At 12,000 Btu, it's best for spaces between 300 and 425 square feet. With a digital display and remote control, users can set the temperature between 64 and 90 degrees Fahrenheit -- an excellent range for a portable unit -- and the onboard timer is programmable for 24 hours. Its biggest drawback, say owners, is the noise. This NewAir is the loudest air conditioner in our report, but most users say its excellent cooling abilities outweigh the loud motor.

Ease of use

User-friendly setup and maintenance. The NewAir AC-12000E is lighter than many portable air conditioners in this category; at about 30 inches high and 16 inches wide, it's also fairly compact for more convenient carrying. Settings adjust with either the digital panel or the remote control, and the NewAir "has a nice built-in thermostat so you can set the room temperature and it automatically switches between fan and A/C mode," according to, a blog dedicated to environmentally friendly homes. The self-evaporative system is also a favorite with users, who appreciate not having the hassle of frequently emptying tanks of water.


A good value. Most owners say the compact NewAir AC-12000E is well built, and they appreciate its feature-rich design (though a number of users say the remote control is only mediocre). Out of about 450 owner reviews, there are relatively few complaints about poor construction. With an energy rating of 10.2 EER, the AC-12000E is about average for annual electricity costs. NewAir includes a one-year limited warranty for the AC-12000E, which is one of the shortest on the market; brands such as Haier, EdgeStar and Koldfront include more comprehensive warranties for their portable air conditioners.
