Who it fits
Good fit for
This unit suits homeowners and small business owners who want a clean, hidden look for their HVAC system. If you have a room between 300 and 450 square feet, this 11,000 BTU model fits well. The 230V requirement means you likely need a dedicated circuit, so it is best for professional installation. The smart features help if you want remote control from your phone. The low noise level makes it ideal for bedrooms or offices where quiet is key. The heat pump works down to -13°F, offering reliable winter heating in moderate climates.
Who should skip it
You should skip this model if you need a DIY setup. The product data states that professional installation is required, and the system is not a plug-and-play unit. If your space is larger than 450 square feet, this 11,000 BTU unit will struggle to maintain comfort. You may need to look at the 17,000 or 22,000 BTU options in the same series. Also, if you do not have a 230V electrical supply, this unit is not compatible. The concealed design requires ductwork, so it is not suitable for open wall mounting without significant renovation.
Verdict: The Della 11,000 BTU Ducted Mini Split offers strong efficiency and quiet operation for hidden installations. It is a solid choice for medium-sized rooms with existing ductwork and professional electrical support.
Key specs explained for Della 11
Cooling Capacity: 11,000 BTU
This value indicates the unit's ability to remove heat from your space. It is suitable for rooms up to 450 square feet. If your area is larger, this unit may struggle to maintain temperature. Smaller rooms will cool faster. You should match this capacity to your room's size to avoid short cycling or inadequate cooling.
Efficiency Rating: 19 SEER2
SEER2 measures seasonal energy efficiency for cooling. A rating of 19 is high for this class. It means the unit uses less electricity to produce the same cooling output compared to lower-rated models. This translates to lower monthly energy bills. When shopping, compare this against standard 14-16 SEER2 units to see potential savings over time.
Voltage: 208-230V
This specifies the electrical requirement for the indoor and outdoor units. It requires a dedicated 230V circuit, not standard 110V outlets. You must have the correct wiring installed by a professional. This is common for mini splits. Ensure your home’s electrical panel can support this load before purchasing to avoid installation issues or safety hazards.
Smart Connectivity: Wi-Fi, Alexa, DELLA App
This allows remote control via smartphone or voice commands. You can adjust temperatures from anywhere using the DELLA App or through Alexa integration. This is useful for scheduling or checking status while away. It adds convenience over standard remotes. Check if your home Wi-Fi network is stable, as connectivity depends on your router’s range and signal strength.
Della 11k Design and Build
The indoor unit is a white, concealed ducted mini split designed for installation in ceilings or attics. According to the listing, the physical dimensions are 27.5 inches in width, 19.3 inches in length, and 7.87 inches in height. The unit weighs 33.1 pounds. This compact form factor allows it to fit into tight architectural spaces without disrupting room aesthetics. The low profile ensures it remains hidden from view while delivering airflow through existing ductwork.
The system includes a built-in condensate pump for reliable water removal, which is critical for concealed installations where gravity drainage may not be feasible. It supports flexible return air positions to accommodate various layout requirements. The design features 0.4 inches of water column static pressure, enabling it to push air through complex or multi-story duct networks. This specification ensures even airflow distribution rather than weak delivery at distant vents.
Control options include a wall-mounted thermostat and a handheld remote. The unit also supports Wi-Fi connectivity for the DELLA App and Alexa integration. These smart features allow you to adjust settings remotely. The finish is a simple white casing that blends with standard ceiling materials. Professional installation is required, as the unit is pre-charged but needs connection to your home electrical system via a 15A fuse rating.
Setup and Everyday Use Details
This unit requires professional installation. It is not a DIY system. The package includes a 16-foot installation kit with 1/4-inch and 3/8-inch copper tubing. You must ensure your electrical supply matches the 208-230V requirement. The maximum fuse rating is 15A. If your line set exceeds 25 feet, you need to adjust the refrigerant charge. The indoor unit is designed for concealed mounting in ceilings or attics. It supports two return air positions to fit various ductwork layouts. A built-in condensate pump helps manage moisture. The system also maintains 0.4 inches of water column static pressure, which allows it to handle complex duct runs. For daily operation, the unit uses inverter technology to adjust compressor speed. This provides stable performance and can reduce power usage by up to 40%. You can control the temperature using the included remote or the wall-mounted thermostat. The unit also connects to Wi-Fi. You can use the DELLA App or Alexa for remote adjustments. Geolocation features allow the system to start before you arrive. The fan offers seven speeds. Airflow reaches 360 CFM. You can set temperatures between 60°F and 90°F. The unit includes smart defrost and high-temperature self-cleaning modes. It operates quietly at 32 dB. The heat pump functions reliably in temperatures down to -13°F.
Before You Buy This Mini Split
You need to verify your home’s electrical capacity before installing this unit. It requires a dedicated 208-230V circuit with a maximum 15-amp fuse. The listing includes a 16-foot installation kit with copper tubing, but you must pay for professional mounting. Since this is a concealed ducted model, you must already have accessible ceiling or attic space for the indoor unit. The system supports complex ductwork with 0.4 inches of water column static pressure, but you should confirm your existing ducts can handle the 360 CFM airflow. Smart control via the DELLA App and Alexa is included, so ensure your Wi-Fi network is stable in the installation area. If your refrigerant line set exceeds 25 feet, you will need to adjust the refrigerant charge, which adds to the installation complexity. This unit covers up to 450 square feet. If you need more cooling power, consider the 17,000 BTU or 22,000 BTU variations available in this series. Regular maintenance involves cleaning the filters and using the high-temperature self-cleaning mode to prevent mold buildup.
Check before you buy
- Confirm you have 208-230V electrical capacity with a 15A fuse.
- Ensure attic or ceiling space exists for the concealed indoor unit.
- Verify existing ductwork can handle 360 CFM airflow volume.
- Check if refrigerant line set length exceeds 25 feet.
- Confirm Wi-Fi signal strength in the installation area.
