There are three main efficiency scores to consider: EER, CEER, and SEER. Power Effectivity Ratio (EER) measures how effectively a cooling system operates, with a score of 12 considered to be an excellent EER. In addition to being highly effective and efficient, the ARC-14 also isn’t the eyesore that some portable AC units are, due to its sleek black design and digital controls.

In a easy air conditioner, the refrigerant, in a volatile liquid type, is passed through a set of evaporator coils across which air inside the room is passed. The refrigerant evaporates and, in the method, absorbs the heat contained within the air. Most of the AC items included on this roundup are Power Star certified. A more prestigious honor is Power Star’s Most efficient checklist. One other thing to contemplate is CEER, or Combined Power Effectivity Ratio. The upper the CEER, the more efficient a window air conditioner is. Based on the units we tested, the common window AC unit places out around fifty two decibels.


Add one other one or two BTUs when you've got a vaulted or excessive ceiling exceeding 9 ft. Local weather: Air conditioning models in hotter climates run more ceaselessly.
