How these models differ from the Della 18K
Della 35000 BTU 17 SEER2 Mini Split
This Della model offers 35,000 BTUs of raw cooling power, which is significantly higher than the original 18,000 BTU unit. It targets large single spaces rather than two smaller rooms. The efficiency rating is 17 SEER2, which is lower than the original 24 SEER2, meaning it uses more energy per unit of cooling. It also runs on 230V and includes Wi-Fi and Alexa smart controls. You should choose this if you need to cool a large open area and do not require dual-zone separation. The outdoor unit is larger and heavier, measuring 46.9 inches wide. It lacks the individual room control of the original setup.
DELLA Optima 23K BTU Soft Airflow
The Della Optima 23K focuses on a single room with 23,000 BTUs of cooling capacity. It features a 23 SEER2 efficiency rating, which is slightly lower than the original 24 SEER2 but still very high. This unit uses CloudAir technology for soft airflow, reducing drafts compared to the original. It operates on 230V and supports Wi-Fi and Alexa. The original unit splits capacity between two 12,000 BTU handlers, while this one concentrates power in one indoor unit. It is ideal for large single rooms where gentle airflow matters. The outdoor unit is 43.2 inches wide. You sacrifice dual-zone flexibility for higher single-zone comfort and efficiency.
YITAHOME 2 Zone 18K BTU Mini Split
The YITAHOME 18K BTU unit also provides dual-zone cooling with two indoor handlers, similar to the original. It achieves a 22 SEER2 efficiency rating, which is lower than the original 24 SEER2. It runs on 230V and includes Wi-Fi and Alexa smart controls. The outdoor unit is smaller and lighter, weighing only 17.6 pounds compared to the original 23.1 pounds. It measures 31 inches wide. You get the same total cooling capacity but with slightly less efficiency. This model is a good alternative if you need a more compact outdoor unit. It maintains the dual-zone capability for separate room control while offering smart connectivity.
COSTWAY 28K Dual Zone 23 SEER2
The COSTWAY 28K Dual Zone offers higher total cooling capacity with two 18,000 BTU indoor handlers. It achieves a 23 SEER2 efficiency rating, which is slightly lower than the original 24 SEER2. It operates on 230V and includes Wi-Fi smart control, though it does not list Alexa compatibility. The outdoor unit is 31.9 inches wide. You gain more total cooling power for larger spaces but lose the specific 12+12 split configuration. The original unit is certified for self-cleaning, while this model does not mention that feature. It is suitable for buyers who need robust dual-zone performance and do not require the highest possible SEER2 score.
TURBRO 27000 BTU Dual Zone Mini Split
The TURBRO 27K BTU Dual Zone provides 12,000 BTUs and 18,000 BTUs for its two indoor handlers. It does not list a SEER2 rating, so efficiency is unknown compared to the original 24 SEER2. It runs on 230V and supports Wi-Fi control. The outdoor unit is significantly heavier at 215 pounds and measures 43.3 inches wide. You get uneven zone distribution compared to the original 12+12 split. This unit is designed for powerful cooling in two distinct areas. It lacks the high efficiency rating of the original. Choose this if you prioritize raw cooling power and can manage a much heavier outdoor unit.
DELLA CloudAir 18k BTU 23.5 SEER2
The Della CloudAir 18K BTU is a single-zone unit with 23,000 BTUs of cooling capacity. It achieves a 23.5 SEER2 efficiency rating, which is slightly lower than the original 24 SEER2. It operates on 230V and includes Wi-Fi and Alexa smart controls. The outdoor unit is 43.2 inches wide. You lose dual-zone capability, which means you cannot control temperatures in two separate rooms independently. This unit is designed for medium rooms up to 1,000 square feet. It offers soft, draft-free airflow. Choose this if you need quiet, comfortable cooling for one large space rather than split-zone control for two smaller rooms.
