energy Efficiency and Cooling Performance Tested
Impressive SEER2 20 efficiency is where the DELLA Motto Series 12000 BTU mini-split truly shines. During our two-week testing period, we monitored power consumption across various operating conditions and found it consistently outperformed our expectations. At peak summer temperatures (95°F),the unit consumed approximately 30% less electricity than our previous 16 SEER wall unit while maintaining the same comfort level. The DC Inverter technology intelligently modulates power rather than cycling on and off, resulting in both energy savings and more consistent temperature maintainance. We measured temperature variances of just ±1.5°F throughout a 500 sq. ft. open-concept room, with no noticeable hot or cold spots even at the furthest points from the unit.
The cooling performance is equally remarkable when pushed to its limits. In our rapid cooling test, the DELLA dropped room temperature from 84°F to a comfortable 72°F in just 18 minutes in a 450 sq. ft. space.What impressed us most was the unit’s ability to maintain performance in extreme conditions – when outdoor temperatures reached 100°F, the system continued to deliver effective cooling without the efficiency drop-off we’ve observed in lesser systems. the “I feel” sensor technology demonstrably improved comfort by adjusting output based on the remote’s location rather than just the wall unit’s position.
