The della 35k btu 3 zone mini split alternatives list helps you find systems that match your specific needs. This original unit covers up to 1950 square feet with three separate zones.

You can compare voltage requirements, indoor unit sizes, and connectivity options side by side. This approach helps you identify which system fits your space and technical requirements. The list includes variations from Della, TURBRO, BRAVO, and COSTWAY. Each entry highlights distinct advantages based on hard numbers. You can make an informed decision by looking at these factual differences.
Our top pick: Della 35K BTU 3-Zone Mini Split.
How these options compare
TURBRO 42k BTU 3-Zone Mini Split
The TURBRO 42K BTU 3-Zone Mini Split offers significantly higher capacity and efficiency than the Della. It delivers 42,000 BTUs across three zones with a 22 SEER2 rating, compared to the Della’s 35,000 BTUs and 19 SEER2. This model uses Wi-Fi for smart control, whereas the Della relies on Alexa integration. It is designed for larger spaces where peak efficiency and raw cooling power matter more than compact dimensions. The outdoor unit is also larger and heavier. You should choose this if you need serious cooling for a big area and prefer app-based Wi-Fi control over voice assistant compatibility.
Della 35K BTU 4-Zone Mini Split
The Della 35K BTU 4-Zone Mini Split expands your control to four separate rooms instead of three. It maintains the same 19 SEER2 efficiency rating as the original 3-zone model. However, it splits the 35,000 BTU capacity across four indoor units (9K+9K+9K+12K), meaning each zone gets less cooling power than the larger units in the 3-zone setup. This option is ideal for homeowners who need to manage four distinct zones independently. You give up the higher individual zone capacity of the 3-zone model to gain an additional room control. It keeps the same compact outdoor dimensions and Alexa integration.
DELLA 35K BTU 3-Zone Ceiling Cassette
The DELLA 35K BTU 3-Zone Ceiling Cassette is designed for commercial spaces or homes with drop ceilings. It shares the 35,000 BTU total capacity and tri-zone configuration with the original Della wall-mount model. However, it uses ceiling cassette indoor units instead of wall-mounted air handlers. This unit is lighter and has different dimensions to fit into ceiling grids. It offers smart connectivity for easy management. You should pick this if you need a discreet, ceiling-mounted solution rather than visible wall units. It provides the same total cooling power but distributes it differently through ceiling cassettes, making it better for commercial aesthetics.
DELLA 45K BTU 4-Zone Mini Split
The Della 45K BTU 4-Zone Mini Split provides more total cooling power and an extra zone. It offers 45,000 BTUs across four equal 9,000 BTU indoor units, compared to the original’s mixed 9K+12K+18K setup. It retains the 19 SEER2 efficiency rating and Alexa integration. This model is best for cooling four equally sized rooms with uniform capacity. You give up the flexibility of varying zone sizes to get consistent cooling across four areas. The outdoor unit is slightly lighter. Choose this if you have four similar-sized rooms and need higher total capacity than the 35K model provides.
BRAVO 30,000 BTU 3-Zone Cassette
The BRAVO 30,000 BTU 3-Zone Cassette offers the highest efficiency on this list at 23 SEER2. It provides 30,000 BTUs across three 9,000 BTU ceiling cassettes, which is less total capacity than the Della’s 35,000 BTUs. It uses Wi-Fi for smart control instead of Alexa. This unit is ideal for users who value high energy efficiency and a compact ceiling format. The indoor units are ceiling-mounted, making it suitable for spaces where wall units are not desired. You get better efficiency and smart app control but sacrifice total cooling power and voice assistant compatibility. It is a strong choice for high-efficiency needs in commercial or modern residential settings.
COSTWAY 3 Ton Ducted Heat Pump
The COSTWAY 3 Ton Ducted Heat Pump is a single-zone, ducted system, unlike the multi-zone mini splits in this list. It offers 36,000 BTUs with 19 SEER2 efficiency. This unit is designed for whole-home ducted cooling and heating, requiring professional installation into existing ductwork. It lacks the individual room controls of the Della 3-zone model. You should choose this if you need a robust, ducted replacement for central air rather than zone-specific control. It is heavier and larger than the compact mini split units. This option suits buyers willing to hire a pro for a single-zone, high-capacity ducted solution.
