Our top pick: Della 35K BTU 4 Zone Mini Split.
How alternatives differ from the Della
DELLA 45K BTU 4 Zone Mini Split
The Della 45K BTU 4 Zone Mini Split upgrades total capacity from 35,000 to 45,000 BTU. It keeps the 19 SEER2 efficiency and quad-zone design but changes the indoor unit mix to 9K, 12K, 12K, and 18K. This larger outdoor condenser handles more cooling load for bigger homes. You still get Alexa support and 208-230V operation. The trade-off is higher initial complexity and cost for the extra power. Choose this if your 1900 sq ft space feels undercooled or you have larger individual rooms requiring the 18K handler. It offers more flexibility in zone sizing than the standard 9+9+12+12 configuration.
Garvee 4 Zone 35000 BTU Mini Split
The Garvee 4 Zone 35000 BTU Mini Split matches the original cooling capacity and 19 SEER2 efficiency. It also supports four independent zones. The key difference is smart control. This model adds Wi-Fi connectivity, whereas the Della relies on Alexa integration. Wi-Fi often allows for more direct app management without needing a smart speaker intermediary. Both units cover similar square footage. You might prefer the Garvee if you want granular app control over each zone. It is a solid alternative for multi-room homes where independent temperature management is the priority. The physical dimensions differ slightly, so check your mounting space.
Albott 18k BTU 230V Mini Split
The Albott 18k BTU 230V Mini Split is a single-zone unit, unlike the four-zone Della. It offers 18,000 BTU cooling at 19 SEER2. It runs on 208-230V power. This model is for one medium room, not a whole house. You give up multi-zone flexibility but gain a simpler, more affordable solution for a single space. It includes self-cleaning features, which the Della lacks. Pick this if you only need to cool one room and want to avoid the complexity of managing multiple indoor handlers. It is a focused tool for targeted comfort rather than whole-home climate control.
Rellytech 18000 BTU 230V Mini Split
The Rellytech 18000 BTU 230V Mini Split is another single-zone option. It provides 18,000 BTU cooling at 19 SEER2 efficiency. It operates on 230V power. This unit is designed for single-zone installations in medium spaces. You lose the ability to control four separate rooms independently. However, you gain a straightforward system for one area. It lacks the smart connectivity features found in the Della. Choose this if you are retrofitting one room and do not need multi-zone management. It is a practical choice for focused cooling where whole-home coverage is unnecessary.
COSTWAY 9000 BTU 115V Mini Split
The COSTWAY 9000 BTU 115V Mini Split is a single-zone unit with significantly lower capacity. It offers 9,000 BTU cooling at 19 SEER2. It runs on standard 115V power, unlike the 208-230V Della. This makes it suitable for small rooms with standard outlets. You give up multi-zone control and high capacity. This model is for small spaces where a dedicated circuit is not available. It is a good fit for bedrooms or offices. It provides efficient cooling without requiring specialized electrical upgrades. Pick this if you need a simple, low-power solution for a single small room.
Mountman 12000 BTU 230V Mini Split
The Mountman 12000 BTU 230V Mini Split is a single-zone unit with 12,000 BTU cooling. It operates at 19 SEER2 efficiency on 208/230V power. It covers up to 750 square feet. This is a focused choice for small spaces. You lose the four-zone capability of the Della. This model is ideal for single rooms where multi-zone complexity is not required. It offers efficient operation for medium-sized areas. Choose this if you need reliable cooling for one room without managing multiple indoor units. It is a practical alternative for targeted comfort in smaller spaces.

Frequently asked questions
Can I use these mini splits with standard 115V outlets?
Yes, but only for smaller units. The COSTWAY 9000 BTU model is designed for 115V power. It is suitable for single small rooms where you cannot install higher voltage circuits. Most other options in this list, including the Della multi-zone systems, require 208-230V electrical connections. You must check your home’s electrical panel before buying a larger unit.
Do these systems support smart home integration?
Several models include smart features. The Della 35K BTU 4 Zone system supports Alexa control. The Garvee 4 Zone unit offers Wi-Fi connectivity for remote management. Other brands like Albott and Rellytech do not list smart capabilities in their specifications. You should verify the specific connectivity options for the model you choose.
What is the difference between the 35K and 45K BTU options?
The main difference is cooling capacity and indoor unit sizing. The Della 35K BTU system provides 35,000 total BTUs with a 9+9+12+12 configuration. The Della 45K BTU alternative offers 45,000 total BTUs using a 9+12+12+18 setup. Both maintain 19 SEER2 efficiency. The 45K model is better for larger homes needing more flexible zone sizing.
Are these units suitable for medium-sized rooms?
Yes, several options fit medium spaces. The Albott 18K BTU and Rellytech 18K BTU models are designed for medium rooms. They both operate on 230V power and offer 19 SEER2 efficiency. The Mountman 12K BTU unit covers up to 750 square feet. These single-zone units are ideal if you do not need multi-room climate control.
How many zones do the multi-zone alternatives support?
The top multi-zone picks support four independent zones. The Della 35K BTU, Della 45K BTU, and Garvee 4 Zone models are all quad-zone systems. This allows you to control the temperature in four separate rooms independently. Single-zone units like the Albott or Mountman models only serve one area.
Do these mini splits include self-cleaning features?
Some models list self-cleaning capabilities. The Della 35K BTU 4 Zone system includes a self-cleaning label, though it may not be fully functional. The Albott 18K BTU model also highlights this feature for maintenance. Other units in the list do not mention self-cleaning in their specifications. Check the attributes for each specific model.
What voltage do the Della multi-zone systems require?
The Della multi-zone systems require 208-230V power. This includes both the 35K BTU and 45K BTU quad-zone units. You cannot plug these directly into standard 115V household outlets. Professional installation is required to ensure the correct electrical connection. Always verify your home’s electrical capacity before purchasing these higher-capacity units.
