The compact version, unlike a window air conditioner, has built-in versatility for versatile installation and convenient off-season storage. However, comparing the performance of portable air conditioners can be difficult because they are not subject to Energy Star standards (like small space heaters), and the efficiency information given by the manufacturer or retailer is not always reliable.Do you want to learn more? find out here 1. On portable air conditioners, don’t look for the Energy Star name. The Department of Energy reports on their website that they do not currently provide Energy Star ratings on portable air conditioners for undisclosed reasons. 2. Instead, use the EER, but be alert. Although Energy Star ratings are not available for portable air conditioners, the Energy Efficiency Ratio (EER), which measures how many BTUs per hour are used for each watt of power drawn, is the next best measure of energy efficiency. A ranking of 10 or higher on the EER scale is considered above average. The EER number is normally found in the product description or specifications, but it is often incorrect even when it is visible. Human error is the most likely cause of this oversight, since the EER number is often under-stated as well as over-stated across a wide range...
