We put together some performance charts to make it easier to see exactly how each unit held up to our testing. In the graphic below, you’ll see different charts for larger and smaller units.
The Keystone unit came in first for the larger units, maintaining a set point of 68 F for 54.3% of its run time, followed by the Toshiba unit with 35.1% and finally Frigidaire unit with 26.5%.
The GE Profile AHTT08BC dominated this test, coming in first among the smaller units with an impressive 94.7%, while the other GE unit maintained 68 degrees F for 32.5% of its run time. We aren’t directly comparing the performance of the larger and smaller units, but it’s worth noting that the AHTT08BC came in first overall, blowing away all of the other units with its ability to maintain a set temperature of 68 F.
In the second test — how well each unit maintained its lowest temperature — the results were much closer together. Among the larger units, the Frigidaire came in first with 58.9%, followed by the Keystone with 54.3% and the Toshiba with 43.7%.
The GE Profile AHTT08BC maintained its lowest temperature 61.6% of the time, while the GE AHEC05AC maintained its lowest temperature 53.6% of its runtime.
For the next set of charts, we looked at each unit’s temperature changes over time.
Among the larger units, the Frigidaire, Toshiba and Keystone units followed very similar patterns as they worked toward the 68-degree set temperature.
The chart of the smaller units is more interesting, showing the GE Profile AHTT08BC getting cooler much more quickly than the AHEC05AC. The AHTT08BC got cooler faster, but it had more dramatic temperature changes. The AHEC05AC cooled more slowly but showed less overall variation.
