Energy Efficiency Ratios (EER) of Portable Air Conditioners

Portable air conditioners’ energy efficiency is most commonly measured by its Energy Efficiency Ratio. This ratio takes into account the unit’s BTUs and power consumption (in wattages). For example, if a unit’s BTU rating is 14,000 and its wattage is 1,400, that portable air conditioner’s EER would be a flat 10.0. The higher the EER, the more energy efficient the unit will be. The Department of Energy recommends using a room air conditioner with an EER of 10.0 or above. Especially if you plan on using your portable air conditioner continuously, choosing a unit with a high EER can provide you with huge savings.
