Specs: Efficiency, Coverage, and Size
Efficiency rating
The GrowthWing unit leads with a 20 SEER2 rating, while the Della model offers 19 SEER2. Higher SEER2 numbers indicate better energy efficiency during cooling operations. This means the GrowthWing compressor adjusts its speed more precisely to match the room's needs, potentially using less electricity for the same cooling output. The Della 19 SEER2 system still provides significant power savings compared to older standards, but the GrowthWing’s extra point gives it a slight edge in long-term operational costs for continuous use. Both units utilize inverter technology to modulate power rather than cycling on and off.
Coverage area
You can expect the GrowthWing to cool spaces up to 1,250 square feet, whereas the Della unit is rated for up to 1,000 square feet. This 250-square-foot difference matters if you are heating or cooling a larger open-plan living area or a spacious garage. Both units deliver 18,000 BTU of cooling capacity, but the GrowthWing’s design allows it to effectively manage air in a slightly larger volume. If your room exceeds 1,000 square feet, the Della unit might struggle to maintain consistent temperatures during extreme weather. For smaller rooms, both perform similarly.
Indoor unit dimensions
Physical installation space is tighter with the GrowthWing. Its indoor unit measures 35.8 inches wide and 11.6 inches high. The Della unit is wider at 37 inches but slightly taller at 12.4 inches. The GrowthWing is also narrower in depth at 8.11 inches compared to Della’s 8.82 inches. If you have limited clearance on your wall or need a sleeker profile, the GrowthWing’s compact footprint is advantageous. The Della model requires a bit more horizontal wall space but fits standard mounting brackets. Measure your wall carefully before choosing based on aesthetic preferences.
Smart control features
Both systems support Wi-Fi connectivity and Alexa voice commands for basic remote control. The GrowthWing explicitly lists a dedicated mobile app as a primary control method, offering scheduling and detailed settings. The Della unit mentions Alexa and Wi-Fi but does not explicitly confirm a proprietary app in the provided data, focusing instead on remote control and voice integration. If you prefer managing your climate through a comprehensive smartphone application with scheduling options, the GrowthWing provides a clearer path. Both allow you to adjust temperatures remotely once connected.
Operating noise level
Quiet operation is critical for bedrooms and living spaces. The Della unit boasts a very low noise level of 29 dBa, making it one of the quieter options available. The GrowthWing operates at 32 dBa, which is still quiet but slightly louder than the Della model. For most people, the difference between 29 and 32 decibels is subtle, but if you are extremely sensitive to sound or the unit will be in a sleeping area, the Della’s lower decibel rating offers a tangible comfort benefit. Both use inverter compressors to reduce noise during startup.
Which Mini Split Fits Your Needs
Budget-conscious buyers seeking top efficiency
The GrowthWing unit offers a 20 SEER2 rating, which is higher than the Della model's 19 SEER2. This spec indicates better energy efficiency during cooling. You will likely save more on electricity bills over time with this variable-speed inverter technology, making it the smarter long-term investment for energy savings.
Users with large spaces needing coverage
GrowthWing covers up to 1250 square feet, while Della covers 1000 square feet. If you are cooling a larger room, garage, or open living area, the extra capacity helps maintain consistent comfort. The higher BTU efficiency ensures the unit handles larger volumes of air without overworking the compressor.
Buyers prioritizing quiet nighttime operation
The Della unit operates at 29 dBa, which is quieter than the GrowthWing's 32 dBa. If you plan to install this mini split in a bedroom or living space where noise matters, the lower decibel rating ensures you enjoy cooling without disruptive sound. This spec is crucial for undisturbed rest.
Those wanting comprehensive smart app control
GrowthWing includes dedicated app control alongside Wi-Fi and Alexa compatibility. Della lists Wi-Fi and Alexa but does not explicitly mention a branded app in its key specs. If you prefer managing your climate through a dedicated smartphone interface for scheduling and monitoring, the GrowthWing offers more direct digital management options.

Frequently asked questions
Which mini split is better for a 1,200 square foot room?
The GrowthWing model is the better choice for this space. It is rated for coverage up to 1,250 square feet, whereas the Della unit tops out at 1,000 square feet. Selecting the larger capacity ensures the unit can maintain your desired temperature without overworking the compressor during peak heat.
Does either unit offer smart home integration?
Yes, both mini splits support smart home integration. Each unit features built-in Wi-Fi connectivity and compatibility with Amazon Alexa. You can control temperature settings, fan speeds, and scheduling through voice commands or a dedicated smartphone application, allowing for convenient remote management from anywhere in your home.
How do the physical dimensions compare between the two brands?
The GrowthWing unit is slightly more compact in width and height. Its indoor panel measures 35.8 inches wide and 11.6 inches high. The Della model is wider at 37 inches and taller at 12.4 inches. Both units share similar depth measurements, so wall clearance requirements are nearly identical for installation.
Is the GrowthWing mini split heavier than the Della option?
Yes, the GrowthWing unit weighs 88 pounds. The Della product data does not list a specific weight, but the GrowthWing is a substantial indoor unit. You should ensure your wall mounting brackets can support this weight securely. Professional installation is recommended to handle the unit safely during placement.
What voltage requirement do these mini splits need?
Both units require a 230V power supply. This is standard for 18,000 BTU mini splits and differs from standard 110V household outlets.
