Pros / The NewAir AC-14100E is quite efficient for a 14,000 Btu air conditioner.

Cons / At 57 decibels, this is the loudest portable air conditioner we reviewed.

 Verdict / The NewAir AC-14100E is a versatile, easily programmable air conditioner with many nice features and the highest airflow in our comparison.

The NewAir AC-14100E is a powerful 14,000 Btu portable AC that can cool a 700-square-foot space in a short time. This versatile unit can run in several different modes for different times of day and various circumstances, like functioning as a fan if the room just needs stale air flushed out. While its annual operating costs are higher than average, it has decent energy efficiency. It is missing a few notable features, such as restart capability, but overall it has a nice feature package.

The NewAir produces consistent airflow with enough power to contribute to the steady airflow of 250 cubic feet per minute. This is the highest airflow among the portable AC units we tested, well above the 200-CFM average.

The AC-14100E functions in three modes: fan, dehumidify and sleep. Fan mode is nice if you just want to circulate air when the room temperature is comfortable on its own, and is a good option for winter months as well. When dehumidifying, this unit can remove up to 2.9 pints of moisture from the air per hour when cooling. In sleep mode, it gradually increases the temperature throughout the night to keep the room at a comfortable temperature while you sleep.

This NewAir model's energy efficiency comes in at EER 9.88, which makes it the fourth-most efficient model among the portable air conditioners we reviewed. However, the estimated annual energy cost is over $122. While the cost is above average, this much cooling power is always going to entail a higher operating cost.

This unit lacks oscillating louvers. If you want to change the direction of the airflow, you have to manually adjust the louvers to direct the air. And since it can't restart automatically, if you are away from home during a power outage, you might come home to an uncomfortably warm house.

This model also lacks any industry ratings from UL, ASHRAE, RoHS or ETL. These ratings would indicate the unit had been tested for hazardous materials and safety standards. One other complaint is that it is the loudest portable AC in our reviews with a noise level of 57 decibels. This isn't significantly louder than most other models. However, when compared with the quietest model we tested – the Amico AP11000, which has a sound output as low as 48 decibels – it is noticeably louder.

This freestanding air conditioner has a one-year compressor warranty, which is below average. At the time of writing this review, the NewAir AC-14110E costs $410, which is slightly more affordable than the industry average of $427.
