*Note: Some models listed below were tested using a new test procedure and have been certified as meeting new conservation standards that are mandatory for all products manufactured beginning on September 15, 2014. Those models have values in the columns "Total Adjusted Volume 2014 (Cubic Feet)" and "Annual Energy Use 2014 (Kilowatt Hours/Year)". Models with values in those columns can be compared directly to other models with values in those columns, but should not be compared to models that do not have values in those columns. Products certified by their manufacturer as compliant with the 2014 standards are expected to be as efficient, if not more so, than products certified to the previous standards.
