How these alternatives compare to Daikin
Daikin 36K BTU 4-Zone Mini Split
This Daikin model keeps the same 20 SEER2 efficiency rating and brand reliability as the 3-Zone unit. The main difference is the zone count. It supports four independent zones instead of three. All indoor units are 9,000 BTU fan coils. This setup works well for four small rooms. You lose the flexibility of a larger 15,000 BTU unit in the original. If you need precise control for more spaces, this is a better fit. It maintains the same smart connectivity and heating capabilities. The trade-off is less capacity per room for larger areas.
DELLA 36K 5-Zone Concealed Ducted
The Della unit offers five zones, which is more than the original three-zone Daikin. It uses concealed ducted indoor units. This changes the installation style completely. You get precise temperature control across five separate areas. The efficiency rating matches the original at 20 SEER2. However, the indoor units are designed for hidden installation. This requires a different setup than wall-mounted fans. It is ideal for homes with existing ductwork or concealed spaces. You gain zone flexibility but lose the ease of standard wall mount installation. The outdoor unit size may vary due to the increased zone count.
Rellytech 12000 BTU 20 SEER2 Mini Split
This Rellytech model is a single-zone system with 12,000 BTU capacity. It is much smaller than the 36,000 BTU multi-zone Daikin. It runs on 115V power, which is easier to install than the 208-230V requirement of the original. The efficiency rating is also 20 SEER2. You get Wi-Fi control similar to the Daikin. This unit is best for one room under 750 sq ft. You give up multi-zone control entirely. It is a practical choice if you only need to cool one space. The lower voltage makes it accessible for standard household outlets without special electrical work.
COSTWAY Blast Pro 18000 BTU 230V
The COSTWAY Blast Pro is a single-zone 18,000 BTU unit. It runs on 230V power, matching the voltage of the original Daikin. It offers 20 SEER2 efficiency and Wi-Fi connectivity. This model is for medium rooms where you need more power than a 12,000 BTU unit. You lose the ability to control multiple zones independently. It is a straightforward solution for one large space. The installation requires a dedicated 230V circuit. It is suitable if you do not need the complexity of multi-zone management. The focus is on efficient cooling for a single area with smart features.
COSTWAY 12000 BTU 115V Mini Split
This COSTWAY unit is a single-zone 12,000 BTU system. It operates on 115V power, unlike the 208-230V original. The efficiency rating is 20 SEER2. It is designed for quiet operation in a single room. You get precise climate control without the overhead of multiple indoor units. This is ideal for bedrooms or small offices. You sacrifice multi-zone capability and higher total capacity. The 115V plug-in option simplifies installation for standard homes. It is a solid choice if you only need to condition one space efficiently. The compact size fits well in standard residential settings.
ROVSUN 9000 BTU 20 SEER2 Mini Split
The ROVSUN model provides 9,000 BTU of cooling power. It runs on 115V power and offers 20 SEER2 efficiency. Wi-Fi control is included for smart management. This unit is intended for small rooms where high capacity is not needed. You give up the 36,000 BTU total capacity of the original. It is also a single-zone system. The trade-off is simplicity and lower power requirements. It is suitable for small spaces like closets or small bedrooms. The 115V operation makes it easy to install in most homes. You do not get the multi-zone flexibility or the high output of the Daikin 36k.

Frequently asked questions
Can I replace the Daikin 36 with a single-zone unit?
Yes, if you only need to cool one room. The Rellytech 12,000 BTU and Costway 12,000 BTU models offer 20 SEER2 efficiency in a single-zone setup. They fit spaces under 750 square feet. You save complexity by avoiding multi-zone piping. These units run on standard 115V power, making installation simpler than a large multi-zone system.
Which alternative supports five zones for larger homes?
The Della 36K 5-Zone Concealed Ducted system is the top choice for five zones. It uses 9,000 BTU units for most rooms and a 12,000 BTU unit for larger spaces. This model hides indoors behind ceilings or walls. It maintains 20 SEER2 efficiency while providing independent climate control across five distinct areas.
Do these alternatives require 230V power?
Only the Costway Blast Pro 18,000 BTU requires 230V power. It suits medium rooms with dedicated 230V circuits. Most other alternatives, including the Rellytech and Costway 12,000 BTU models, run on standard 115V power. The Daikin 36K alternatives also use standard wiring. Check your electrical panel before choosing the 230V option.
Can I control these mini splits via Wi-Fi?
Yes, several models include Wi-Fi smart control. The Rellytech, Costway Blast Pro, and Rovsun units all feature Wi-Fi connectivity. This allows you to adjust settings from your phone. The Daikin models also support smart home integration. You get remote management for temperature and mode changes without needing a physical remote nearby.
Which option is best for small rooms?
The Rovsun 9,000 BTU and Rellytech 12,000 BTU units are ideal for small spaces. The Rovsun model is compact and quiet, fitting rooms where raw power is not critical. The Rellytech unit offers higher capacity for slightly larger small rooms under 750 square feet. Both provide 20 SEER2 efficiency for energy savings in smaller areas.
How does the 4-zone Daikin compare to the 3-zone?
The 4-zone Daikin supports four independent 9,000 BTU indoor units instead of three. It keeps the same 20 SEER2 efficiency rating. This setup is better for four small rooms needing precise control. The 3-zone model mixes 9,000 and 15,000 BTU units for varied room sizes. Choose the 4-zone for uniform small spaces.
Are there concealed ducted options available?
Yes, the Della 36K 5-Zone Concealed Ducted system offers hidden installation. The indoor unit mounts inside walls or ceilings, leaving only vents visible. This style suits modern homes where aesthetics matter. It provides five zones with 20 SEER2 efficiency. Other listed models are wall-mounted, which are more visible but easier to install.
