Key specs explained for this unit
23 SEER2
This efficiency rating measures how much cooling you get per watt of electricity. A higher number means lower energy bills. You save more on power costs compared to units with lower SEER2 values. This metric helps you compare running costs across different brands. It indicates the system uses DC Inverter technology to adjust compressor speed. This maintains steady temperatures without frequent on-off cycles. You benefit from consistent comfort and reduced energy waste in your home.
38,000 BTU/h
This is the total cooling output of the entire system. It combines the capacity of all three indoor units. This high capacity targets larger living spaces. You can cool up to 2,600 square feet with this single outdoor condenser. Compare this to smaller units that serve only one room. This spec helps you determine if the system matches your home's size. It ensures adequate cooling power for open areas or multiple connected rooms simultaneously.
3 Zone
This indicates the system controls three separate indoor air handlers. You get two 12,000 BTU heads and one 24,000 BTU head. Each zone operates independently via its own remote. You can set different temperatures for each room. This suits homes with varying heat loads. Compare this to single-zone units that control only one space. This flexibility allows you to save energy by cooling only occupied areas. It provides personalized comfort for bedrooms, offices, or living spaces.
Wi-Fi, Smartphone App
This connectivity allows you to control the system remotely. You can adjust settings from anywhere using your phone. This feature adds convenience for managing your home climate. You can change modes or schedules without being near the unit. Compare this to basic models that require a physical remote only. This smart capability integrates with your daily routine. You benefit from precise temperature management and remote monitoring. It supports intelligent modes like eco-saving and 4D airflow control.
Design and build details
The outdoor condenser measures 31.9 inches in width, 12.1 inches in height, and 7.48 inches in length. It weighs 18.7 pounds. The listing describes the finish as white with a line set. These dimensions suggest a compact footprint for the unit. You can place it against a wall or on a pad without taking up excessive space. The weight is manageable for professional installers to position securely.
Indoor units come in white. You receive two 12,000 BTU heads and one 24,000 BTU head. This layout allows you to cover up to 2,600 square feet. The 24,000 BTU unit likely suits larger rooms like living areas. The smaller heads fit bedrooms or offices. Each indoor unit includes an independent remote. This lets you set different temperatures for each zone. You do not need to adjust the whole house at once.
According to the listing, the system uses R-32 refrigerant. It is pre-charged for easier installation. The package includes three sets of 16-foot copper pipes. Standard sizes are 2x1/4 inch plus 3/8 inch, and 1/4 inch plus 1/2 inch. This length gives you flexibility in routing lines between the outdoor and indoor units. Professional setup is required to ensure proper vacuuming and refrigerant balance. The design prioritizes straightforward installation for larger homes.
Setup and daily use guide
Professional installation is required for this system. The package includes three sets of 16-foot copper pipes with standard sizes of two 1/4-inch plus 3/8-inch lines and one 1/4-inch plus 1/2-inch line. The outdoor unit comes pre-charged with R-32 refrigerant. A qualified technician must perform proper vacuuming and refrigerant balancing to ensure long-term durability and correct performance. The system requires a maximum fuse size of 35A. You must connect the indoor heads to the single outdoor condenser using the provided line sets. Once installed, you can control each zone independently. Each indoor unit includes its own remote control. You can set different temperatures for specific rooms, such as bedrooms or offices. This allows you to customize comfort while maximizing energy efficiency. The system supports Wi-Fi connectivity. You can use a smartphone app to adjust settings from anywhere. Features include intelligent modes like "I Feel" and Eco energy saving. You also have access to versatile 4D airflow and multiple operating modes for heating, cooling, and drying. The unit operates quietly, with noise levels as low as 28dB. This ensures your sleep remains undisturbed during cooling or heating cycles. Note that the self-cleaning function does not perform an actual cleaning operation, though the option appears on the display. The system is designed for spaces where not all units run at full power simultaneously. If total indoor capacity exceeds outdoor output, performance may slow when all zones operate at high demand. For consistent high demand across all three zones, consider a larger setup.
Before You Buy This Unit
Before you buy this Della 38K BTU 3 Zone Mini Split, verify your electrical capacity. The listing specifies a maximum fuse size of 35A. Ensure your home’s panel can support this load without upgrades. Check your available space for the outdoor condenser, which measures 31.9 inches wide.

This unit supports three zones. It includes one outdoor condenser and three indoor heads. The indoor units provide 12,000 BTU, 12,000 BTU, and 24,000 BTU respectively. You can control the temperature in each room independently. This tri-zone setup allows for targeted climate management across different areas of your home.
What is the cooling capacity of the Della 38K BTU system?
The total cooling capacity is 38,000 BTU per hour. This figure comes from combining the output of all three indoor units. The two smaller heads offer 12,000 BTU each, while the larger head provides 24,000 BTU. This total capacity is designed to handle larger living spaces or multiple rooms at once.
Is this mini split efficient for electricity usage?
Yes, it features a 23 SEER2 rating. This metric measures the cooling output per watt of electricity consumed. A higher SEER2 number indicates better energy efficiency. You can expect lower power costs compared to units with lower ratings. This efficiency helps reduce your monthly electricity bills while maintaining comfortable indoor temperatures.
What refrigerant does the outdoor unit use?
The outdoor condenser comes pre-charged with R-32 refrigerant. This type of refrigerant is common in modern mini split systems. It is generally more environmentally friendly than older options. The unit arrives ready for installation, which simplifies the setup process for your professional installer.
How long are the included copper pipes?
The package includes three sets of 16-foot copper pipes. These lines connect the indoor heads to the outdoor condenser. The standard sizes vary slightly between zones. Two zones use 1/4-inch and 3/8-inch lines, while the third uses 1/4-inch and 1/2-inch lines. This length covers most standard residential installations.
What electrical requirements are needed for installation?
You must ensure your electrical panel can support a 35A maximum fuse. The system draws significant power due to its high capacity. Verify that your home’s wiring and breaker box can handle this load. Professional installation is required to safely connect the unit to your home’s electrical system without overloading circuits.
