6 Best Alternatives to the DAIKIN 36K BTU 4-Zone Mini Split (2026)
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
The Daikin 36k BTU 4-zone mini split delivers precise multi-room climate control with four independently controlled indoor units. It offers high efficiency at 20 SEER2 and smart connectivity via Wi-Fi for modern homes. However, you might need different specifications for your space. Perhaps you require a different number of zones, such as three or five. Or you may need a single-zone unit for a smaller room. Some buyers prefer a concealed ducted design for aesthetics. Others need a system that runs on a standard 115V circuit instead of 230V power.
We selected these alternatives because their published specs overlap with the original Daikin model. Each option matches key requirements like SEER2 ratings or voltage needs. This list covers variations in zone count, power requirements, and installation types. You can find a system that fits your specific electrical setup and room layout. Whether you need hidden ducts or a budget-friendly single-zone unit, these choices provide comparable performance. Review the specs to determine which configuration best suits your home's unique demands.
How each alternative compares
Daikin 36k BTU 3-Zone Heat Pump
This Daikin model reduces the zone count from four to three, pairing two 9,000 BTU units with one 15,000 BTU indoor fan coil. You gain more cooling power in the third room, which suits larger spaces like master bedrooms or living areas. The efficiency rating remains at 20 SEER2, matching the original’s energy performance. You give up one zone of independent control, which may not work if you need to manage four separate small rooms. This option is best for homes where three zones provide sufficient coverage with higher capacity in the primary area.
DELLA 36K 5-Zone Concealed Ducted
The Della unit increases the zone count to five, using four 9,000 BTU units and one 12,000 BTU unit for concealed ducted installation. You get more zones and a hidden aesthetic, which is ideal for modern interiors where visible indoor units are undesirable. The efficiency rating is also 20 SEER2, ensuring similar energy costs. You sacrifice the wall-mounted convenience of the Daikin, as these units require ductwork and professional installation. This alternative is best for renovations or new builds where aesthetics and multi-room control are priorities over simple wall mounting.
Rellytech 12000 BTU 20 SEER2 Mini Split
This Rellytech model is a single-zone unit with 12,000 BTU capacity, designed for 115V circuits rather than the 208-230V power required by the Daikin. You get a simpler installation that fits standard household outlets, avoiding the need for specialized electrical work. The efficiency rating is 20 SEER2, providing comparable energy savings per unit of cooling. You give up multi-zone capability entirely, as this unit serves only one room. This option is best for single small rooms or apartments where standard electrical infrastructure limits your choices and multi-zone complexity is unnecessary.
COSTWAY Blast Pro 18000 BTU 230V
The COSTWAY Blast Pro offers 18,000 BTU cooling in a single-zone configuration, requiring 230V power like the Daikin outdoor condenser. You get more cooling capacity for a single large room, which may be necessary for open-plan living spaces or sunrooms. The efficiency rating is 20 SEER2, matching the original’s energy performance standards. You sacrifice the ability to control multiple rooms independently, as this is a single-zone system. This alternative is best for users who need higher individual room capacity and have the necessary 230V electrical setup but do not require multi-zone distribution.
COSTWAY 12000 BTU 115V Mini Split
This COSTWAY unit provides 12,000 BTU cooling on a standard 115V circuit, making it suitable for small rooms with limited electrical options. The efficiency rating is 20 SEER2, aligning with the original’s energy efficiency goals. You gain the flexibility of using existing household outlets without upgrading to 208-230V power. You give up significant cooling capacity and multi-zone functionality, as this unit is designed for small, single-room applications. This option is best for small bedrooms, offices, or additions where standard electrical outlets are the only available power source and large cooling capacity is not required.
ROVSUN 9000 BTU 20 SEER2 Mini Split
The ROVSUN model delivers 9,000 BTU cooling on a 115V circuit, matching the capacity of each individual indoor unit in the Daikin system. You get a practical solution for small rooms using standard electrical outlets, avoiding the need for complex 208-230V wiring. The efficiency rating is 20 SEER2, ensuring similar energy performance per unit. You sacrifice multi-zone integration and smart connectivity features, as this is a standalone single-zone unit. This alternative is best for users who need to cool multiple small rooms individually with standard outlets and do not require a unified multi-zone control system.

Frequently asked questions
Can I replace a 4-zone Daikin with a 5-zone system?
Yes, you can upgrade to a 5-zone configuration. The Della 36K 5-Zone Concealed Ducted unit offers five independent zones using 9,000 and 12,000 BTU indoor units. This setup hides the indoor components for a cleaner look while maintaining 20 SEER2 efficiency. It suits homes where aesthetics and multi-room control are priorities.
What if I only need cooling for one large room?
You should consider a single-zone unit instead of a multi-zone system. The COSTWAY Blast Pro 18000 BTU provides 20 SEER2 efficiency for larger spaces. It requires a 230V circuit and includes Wi-Fi smart control. This option eliminates the complexity and cost of multiple indoor units when you only need to condition one area.
Do these alternatives support smart home apps?
Most listed options include Wi-Fi connectivity for app management. The Daikin 36K 4-Zone and 3-Zone models offer smart features for modern homes. The Della, Rellytech, COSTWAY Blast Pro, and ROVSUN units also feature Wi-Fi control. This allows you to adjust temperatures remotely from your smartphone regardless of the brand you choose.
Which system works with standard 115V outlets?
Several single-zone units operate on standard 115V circuits. The Rellytech 12000 BTU, COSTWAY 12000 BTU, and ROVSUN 9000 BTU models all use 115V power. These are practical choices for small rooms or additions where installing a 230V line is not feasible. They deliver efficient cooling without requiring specialized electrical infrastructure.
How does the 3-zone Daikin differ from the 4-zone model?
The 3-zone model reduces the number of indoor units from four to three. It pairs two 9,000 BTU units with one 15,000 BTU unit. This configuration provides more cooling power in the third room compared to the 4-zone setup, which uses four identical 9,000 BTU units. Both maintain 20 SEER2 efficiency.
Are there options for hidden ducted installation?
Yes, the Della 36K 5-Zone Concealed Ducted system is designed for hidden installation. It fits inside walls or ceilings for a minimalist aesthetic. The unit includes a line set and offers 20 SEER2 efficiency. This option is ideal for homeowners who prioritize clean interior design while needing climate control across five separate zones.
What is the weight difference between these mini splits?
Indoor unit weights vary significantly by brand and model. The Daikin 36K 4-Zone weighs 140 pounds total. The Della 5-Zone indoor unit weighs 33.1 pounds. The COSTWAY Blast Pro is lighter at 20.9 pounds. The ROVSUN 9000 BTU unit weighs 70 pounds. These differences affect mounting requirements and structural support needs.
