Best Window Air Conditioners of 2024
We’ve put together some performance charts to make it easier to see exactly how each unit performed during our tests. In the chart below, you’ll see different charts for larger and smaller units.
The Keystone unit came in first among the larger units, maintaining a set temperature of 68 F for 54.3% of its operating time, followed by the Toshiba unit at 35.1%, and finally the Frigidaire unit at 26.5%.
The GE Profile AHTT08BC dominated this test, coming out on top among the smaller units with an impressive 94.7%, while the other GE unit maintained 68 degrees F for 32.5% of its runtime. We won’t be directly comparing the performance of the larger and smaller units, but it’s worth noting that the AHTT08BC came out on top, blowing away all the other units with its ability to maintain a set point temperature of 68 F.
In the second test—how well each unit maintained its lowest temperature—the results were much closer. Of the larger units, the Frigidaire came in first at 58.9%, followed by the Keystone at 54.3% and the Toshiba at 43.7%.
The GE Profile AHTT08BC maintained its lowest temperature for 61.6% of the time, while the GE AHEC05AC maintained its lowest temperature for 53.6% of the operating time.
For the next set of graphs, we looked at the temperature changes of each unit over time.
Among the larger units, the Frigidaire, Toshiba, and Keystone units followed much the same pattern when operating to the set temperature of 68 degrees.
The graph for the smaller units is more interesting and shows that the GE Profile AHTT08BC cools much faster than the AHEC05AC. The AHTT08BC cooled faster, but had more dramatic temperature changes. The AHEC05AC cooled slower, but showed less overall variation.
