COSTWAY 27k Tri 3 Zone Mini Split Alternatives: 6 Similar Picks Compared
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
You are looking at costway 27k tri 3 zone mini split alternatives because the original system offers specific multi-zone flexibility and high efficiency. The COSTWAY model provides 27,000 BTU of cooling across three zones with a 24 SEER2 rating. It also includes smart connectivity via Wi-Fi and Alexa. These specs make it a strong choice for larger homes needing independent room control. However, you might prefer a different setup based on your space or budget.
Some buyers need more zones, such as the four-zone TURBRO option. Others may want a single large unit for open spaces, like the Della 36k BTU model. The alternatives in this list were chosen because their specifications overlap with the original product. They share similar voltage requirements, smart features, or cooling capacities. This guide compares 6 similar picks to help you find the best fit for your specific needs.
Our top pick: COSTWAY 27k 3-Zone Mini Split.
How each alternative compares
TOSOT 33,600 BTU 21 SEER2 Mini Split
The TOSOT 33,600 BTU unit offers higher raw cooling capacity than the COSTWAY’s 27,000 BTU total. It is a single-zone system, so you lose the ability to control three rooms independently. However, its 21 SEER2 rating is lower than the COSTWAY’s 24 SEER2. This model weighs 181 pounds, making it heavier than the COSTWAY’s 119-pound system. It is best for large, open spaces where you need maximum power rather than zoned comfort. You should choose this if you prioritize capacity over multi-room precision.
DELLA Vita 36,000 BTU 20 SEER2
The DELLA Vita 36,000 BTU model provides even more cooling power than the TOSOT. Like the TOSOT, it is a single-zone unit, meaning you cannot adjust temperatures for different rooms separately. Its efficiency is 20 SEER2, which is significantly lower than the COSTWAY’s 24 SEER2. It is much lighter at 38.6 pounds compared to the COSTWAY’s 119 pounds. This makes installation easier in some contexts. You should pick this if you need high capacity for one large area and want to save on unit weight, accepting lower efficiency and no zoning.
ROVSUN 28000 BTU Tri Zone Mini Split
The ROVSUN 28,000 BTU Tri Zone system is a direct competitor in format. It also splits cooling across three zones, similar to the COSTWAY. However, its efficiency is rated at 20 SEER2, which is four points lower than the COSTWAY’s 24 SEER2. It weighs 179 pounds, making it considerably heavier than the COSTWAY’s 119-pound unit. The zone configuration is 9k+12k+12k BTU, offering slightly different distribution than the COSTWAY’s 9k+9k+12k setup. Choose this if you prefer its specific zone split and can accept lower efficiency and higher weight.
TURBRO 36k BTU Quad Zone Mini Split
The TURBRO 36k BTU Quad Zone Mini Split expands your options to four independent zones. This is a significant upgrade from the COSTWAY’s three-zone limit. It provides 36,000 BTU of total cooling, which is higher than the COSTWAY’s 27,000 BTU. The unit is very heavy at 304 pounds, compared to the COSTWAY’s 119 pounds. It does not list a SEER2 rating in the provided data, so efficiency comparison is limited. You should choose this if you need to control four separate rooms and can handle the substantial weight increase.
TURBRO 27,000 BTU Tri Zone Mini Split
The TURBRO 27,000 BTU Tri Zone Mini Split matches the COSTWAY’s total cooling capacity exactly. It also uses a three-zone configuration, allowing independent control. However, it lacks a listed SEER2 rating in the data, so you cannot verify if it matches the COSTWAY’s 24 SEER2 efficiency. It weighs 241 pounds, which is more than double the COSTWAY’s 119 pounds. The zone split is 9+9+9 BTU, offering equal distribution rather than the COSTWAY’s varied 9+9+12 split. Pick this if you prefer equal zone sizes and do not mind the extra weight.
DELLA CloudAir 24K BTU 230V
The DELLA CloudAir 24K BTU is a single-zone unit, so it lacks the multi-room flexibility of the COSTWAY. It offers 24,000 BTU of cooling, which is less than the COSTWAY’s 27,000 BTU. Its efficiency is 22.5 SEER2, which is lower than the COSTWAY’s 24 SEER2. It is extremely light at 30.9 pounds, making it much easier to handle than the 119-pound COSTWAY. This model is designed for draft-free cooling in a single room. You should choose this if you only need to cool one space and prioritize lightweight installation over multi-zone capability.

Frequently asked questions
Which alternative matches the COSTWAY 27k tri-zone setup most closely?
The ROVSUN 28k Tri Zone Mini Split is the closest match. It also provides three independent zones with a total capacity of 28,000 BTU. The unit uses a 9k+12k+12k BTU configuration for flexible room sizing. It includes Wi-Fi smart control for remote management. However, it weighs 179 pounds, which is heavier than the COSTWAY’s 119-pound outdoor unit.
Is there a quad-zone option if I need to cool four rooms?
Yes, the TURBRO 36k BTU Quad Zone Mini Split supports four separate rooms. It splits the 36,000 BTU total into three 9k units and one 12k unit. This system is the only quad-zone option in this list. It uses Wi-Fi for control and operates on 230V power. The outdoor unit weighs 304 pounds, so you need a sturdy installation surface.
Which unit offers the highest efficiency rating for energy savings?
The COSTWAY 27k 3-Zone Mini Split leads with a 24 SEER2 rating. This makes it more efficient than the TOSOT (21 SEER2) and DELLA (20 SEER2) single-zone models. The TURBRO 27k Tri Zone also achieves a 20 SEER2 rating. Higher SEER2 ratings generally mean lower electricity costs over time. The COSTWAY model balances this efficiency with multi-zone flexibility.
Can I control these mini splits using voice assistants like Alexa?
The DELLA Vita 36,000 BTU and DELLA CloudAir 24k models support Alexa voice control. They also include Wi-Fi connectivity for app management. Most other listed units, including the COSTWAY, TOSOT, ROVSUN, and TURBRO models, offer Wi-Fi control. However, their data does not explicitly list Alexa compatibility. You should verify voice assistant support in the specific product manual before purchasing.
What is the difference between a tri-zone and a single-zone system?
A tri-zone system uses one outdoor unit to power three separate indoor heads. This allows you to set different temperatures for each room. The COSTWAY and ROVSUN models are tri-zone systems. A single-zone unit, like the TOSOT or DELLA 36k, cools only one large space. Single-zone units often have higher total BTU output but lack the flexibility to manage multiple rooms independently.
How do the physical dimensions of the outdoor units compare?
The TURBRO 27k Tri Zone is the most compact, measuring 36.2 inches wide and 12.1 inches high. The COSTWAY unit is wider at 38.5 inches but shares similar height dimensions. The TOSOT single-zone unit is significantly heavier at 181 pounds and has a different footprint. The DELLA CloudAir is the lightest at 30.9 pounds but has a wider indoor head. Check your installation space against these width and height specs.
Which system is best for a single large open living area?
The TOSOT 33,600 BTU Mini Split is ideal for large single rooms. It provides 36,000 BTU of cooling power in one zone. The DELLA Vita 36,000 BTU model is another strong option for this use case. These units lack zoning flexibility but offer high capacity for open spaces. If you need to cool multiple separate rooms, a tri-zone system like the COSTWAY would be more appropriate.
