Which Window Air Conditioner Uses The Least Electricity?

Based on the actual power consumption of 1,037 units studied, the Frigidaire FFRE053WAE window AC uses the least amount of electricity, consuming 0.0354 kWh per hour, 0.849 kWh per day, and 25.48 kWh per month.

The average consumption level is 0.0938 kWh per hour, 2.071 kWh per day, and 6.22 kWh per month. The Frigidaire FFRE053WAE window AC uses the least electricity in comparison to the average window air conditioning unit—about 20 percent less.

The Amana AMCA0508W window AC is the most efficient, with an average consumption of 6.22 kWh per month, 2.071 kWh per day, and 0.0938 kWh per hour. The LG LW8016ER and Amana AMCA0807AW use the next least amount of power, at 32 percent and 35 percent less than average.

The Frigidaire FFRE054Q1 uses the most power, about 20 percent more than the average unit. The top ten most energy-hungry window air conditioning units use about 50 percent more power than the average. The top ten least efficient windows ACs use about 70 percent more power than the average.

The Frigidaire FFRE053WAE, Electrolux EWF03611LW, and Samsung WA12J5100EW are the top three most efficient models in our survey. The LG LW8016ER and Amana AMCA0807AW are the second and third most efficient units. All three of these models have the Energy Star label, promising that they meet or exceed Energy Star requirements for energy efficiency.

The Frigidaire FFRE053WAE and Electrolux EWF03611LW have the ENERGY STAR Most Efficient 2012 label, while the Amana AMCA0807AW has the Energy Star 2006 Version 1.0 label. The units not tested or listed as meeting requirements do not have the ENERGY STAR label and therefore are not considered energy efficient as of this writing.

 

What Are The Dimensions Of A Small Window Air Conditioner?

The smallest LG LW6017R 5,000 BTU air conditioner measures 14.38 x 17.31 x 11.13 inches in length, width, and height. It requires a minimum of 21-inch-wide windows and a maximum of 35-inch-wide windows (to fit the window seal).

The Samsung WF10J5200DW is the smallest, at 9.12 x 11.79 x 9.61 inches in length, width, and height. The Amana AMCA0508W uses a 16-inch-wide window, which is smaller than the minimum recommended size for this device—24½ inches wide by 21 inches high.

No way to fit this window AC in a 24×21-inch window can be found on the Internet or through the manufacturer’s literature, so ACI does not list it as compatible with this brand of window AC. The Samsung WF10J5200DW is also not recommended for use in 24×21-inch windows, but it fits through the window seal.

The Frigidaire FFRE053WAE measures 19.87 x 13.83 x 13.03 inches in length, width, and height. It requires a minimum of 24½-inch-wide windows and a maximum of 36½-inch-wide windows (to fit the window seal).

It comes with two filters that install on the sides of the unit—an EZ Fit Filter (to go between the unit and outside air) and an HVAC Filters AC Filter (to go between outside air and inside air).

The LG LW6017R and Samsung WF10J5200DW are the two smallest models that come with a reusable window air conditioner filter. The Frigidaire FFRE053WAE does not use an EZ Fit Filter, it instead comes with two reusable filters that snap on the sides of the unit.

These reusable filters are kept detached but stored in a transparent bag so they can be accessed easily when needed. The Electrolux EWF03611LW also comes with two filters, but they must be purchased separately, at an additional cost of $39.99 per set of filters (for a total of $139).
