How these units differ from Della
DELLA 18K BTU Dual Zone Mini Split
The Della 18K BTU Dual Zone offers 18,000 BTU total cooling, split as 7,000 and 12,000 BTU per zone. This is significantly less capacity than the 27,000 BTU original. It maintains the same 22 SEER2 efficiency rating and smart app connectivity. The outdoor unit is smaller, measuring 30.2 inches wide and weighing only 16.5 pounds. You should choose this if your spaces are small and the original unit would be oversized. It provides the same brand reliability and inverter technology but with lower cooling power for tighter budgets or smaller footprints.
