Which Portable Air Conditioner is the Coldest?

Air Conditioners America tested several portable air conditioners at our offices to measure how cold each AC unit can perform in a room. This comparison helps you determine which is the coldest unit that can meet your needs. For instance, if your room temperature is 100 F and you would like to cool it down to 75 F then you will need a unit that can drop the temperature by 25 degrees.

 Highest Temperature Drop at Unit (higher the better)

Alen™ C535	28.5°
Alen™ C425	28.5°
SPT WA-1300E	27.5°
Amcor PLM16000E	27.5°
Amcor PLM14000E	27.1°
Alen™ C320	27.0°
Amcor ALW12000E	22.7°
Amcor ALD12000	22.7°
SPT WA-1210	22.7°
Delonghi PAC-C100	20.8°
SPT WA-1220M	20.3°

Recommendations: We highly recommend the higher powered Alen™, Amcor and Sunpentown portable air conditioners. These units performed the best in cooling our test room. These units also produced the coldest air as measured at the air conditioner. We do not recommend the Sunpentown WA-1220E or the DeLonghi PAC260 as these units performed poorly in our cooling tests.

Test Methodology - Temperature Decrease at Unit

Each unit was tested on low fan speed without the exhaust hose attached to the unit to maximize the cooling effect. Two thermometers were used to verify the results and were placed directly in front of the AC register to measure the lowest temperature. The AC unit was set to the lowest setting (62F) and operated for 5 minutes before the temperature was recorded. The compressor for each model remained "ON" throughout the entire test. (Note: Amcor PLM14000E was lowered to 64F - it's lowest setting).
