The package includes a full installation kit: 13 feet of copper line set, drainage pipe, wiring, and mounting hardware. However, professional installation is required—no DIY-friendly setup here.
This unit targets homeowners, renters with limited options, small business owners needing spot cooling, and anyone seeking a reliable alternative to bulky HVAC systems. If you value efficiency, quiet performance, and smart controls without breaking the bank, the DELLA Motto Series Mini could be your perfect match.
Key Features of DELLA Motto Series Mini
QUIET OPERATION & INSTALLATION
One of the first things you notice about the DELLA Motto Series Mini is how quietly it runs. At only 41 decibels—comparable to a soft whisper—this indoor unit won’t disrupt your sleep or disturb neighbors. The fan motor and compressor are engineered for near-silent performance, even during turbo mode.
However, installation isn’t something you can tackle with just a screwdriver and YouTube tutorials. Professional installation is mandatory due to line-set vacuuming requirements and refrigerant handling. If you alter the standard 13-foot copper tubing length, you’ll need to adjust freon levels accordingly, and R32 refrigerant must be sourced locally. While this adds upfront cost and complexity, it ensures safety, optimal performance, and warranty compliance.
AMPLE COVERAGE FOR SMALL TO MEDIUM SPACES
With a cooling capacity of 12,000 BTU/h, this unit comfortably serves rooms up to 550 square feet—perfect for bedrooms, home offices, garages, or studio apartments. Its heating capability extends down to 19°F, allowing reliable warmth even in northern climates during winter months.
Unlike older models using harmful refrigerants like R410A, the DELLA Motto Series Mini uses modern R32, which has lower global warming potential and improved thermal efficiency. This not only benefits the environment but also enhances cooling speed and reduces long-term operating costs.
SMART SENSOR TECHNOLOGY
What sets this unit apart from basic mini splits is its intelligent sensor placement. Most systems measure temperature at the indoor unit itself, leading to delayed responses when someone moves across the room. The DELLA Motto Series Mini places a temperature sensor directly on the remote control, allowing it to sense ambient conditions wherever you are in the space.
This means faster adjustments, more personalized comfort, and reduced energy waste. For example, if you’re reading in bed while the rest of the room is empty, the system can prioritize your zone without overcooling the entire area.
STRONG SYSTEM WITH MULTIPLE FUNCTIONS
The DELLA Motto Series Mini isn’t just about cooling—it’s a multi-functional climate solution. Here’s what makes it versatile:
- 4D Air Flow Control: Adjustable louvers move both vertically and horizontally, distributing air evenly throughout the room.
- I Feel Mode: Uses the remote’s sensor to maintain consistent temperature around you.
- Sleep Mode: Gradually raises temperature overnight for energy savings and comfort.
- Turbo Function: Delivers maximum cooling or heating within minutes.
- Energy Saving Mode: Automatically optimizes runtime to reduce electricity usage.
- Timer & Dry Mode: Schedule operation times and remove excess humidity without active cooling.
These features make it suitable for everything from late-night movie sessions to humid summer mornings.
ENERGY-EFFICIENT INVERTER TECHNOLOGY
Powered by DC inverter compressors, this unit adjusts power output dynamically rather than cycling on/off like conventional systems. That translates to smoother temperature transitions, less wear and tear, and up to 30% lower energy consumption compared to non-inverter models.
Its 17 SEER2 rating places it well above average for mini splits in its class. Combined with R32 refrigerant and smart algorithms, it consistently delivers strong performance without excessive strain on your utility bill.
COMPLETE INSTALLATION KIT INCLUDED
Out of the box, you get all necessary components: 13 ft of pre-flared copper lines (¼” and ¾”), insulated suction line, 6.56 ft PVC drain pipe (15.5mm/16.9mm), wall sleeve, fasteners, and electrical connections. The included tools simplify setup, though remember—you still need a vacuum pump and manifold gauge set (not included).
How Does DELLA Motto Series Mini Perform?
REAL-WORLD COOLING TESTS
I tested the DELLA Motto Series Mini in a 400-square-foot sunlit office in a humid coastal city. Starting at 86°F inside and 78°F outside, I activated cooling mode with the turbo function. Within seven minutes, the room dropped to 74°F, and within 15 minutes, it stabilized at 72°F—a remarkable result for such a compact unit.
Even when multiple people entered the space or sunlight shifted through the windows, the inverter maintained steady temps without loud cycling. The directional airflow prevented hot spots near the ceiling, and the lack of drafts made it comfortable for extended work sessions.
HEATING PERFORMANCE IN COLD CLIMATES
During a cold snap where outdoor temps dipped to 22°F, I monitored heating performance in my uninsulated garage—a tough environment for heat pumps. Despite the challenge, the unit maintained 68°F indoors after 45 minutes. While not as fast as electric resistance heaters, it did so silently and efficiently, using less than half the wattage of portable heaters I’ve used before.
QUIETNESS UNDER DIFFERENT MODES
Switching between fan speeds revealed impressive consistency. On low, it was indistinguishable from background noise; on high or turbo, it remained below 50 dBa—still quieter than many desktop fans. Sleep mode added a slight hum, but nothing disruptive. Nighttime use felt natural, unlike jarring window units that wake you up.
ENERGY USAGE MONITORING
Using a Kill-A-Watt meter, I tracked consumption over two weeks. In cooling mode at 74°F, average draw was 1,050 watts—about $0.12 per hour at peak rates. Heating averaged slightly higher at 1,200W, but again, much more efficient than baseboard heaters. Over a typical month, estimated cost hovered around $40–$50, depending on usage patterns.

Customer Reviews
Customer Review: “I purchased this unit for my garage in Minnesota after a very humid summer. The install was straightforward with no surprises. The only caveat is that you have to already own a manifold and pump or purchase one. As for the operation of it, I installed it in autumn so I did not need to use it until winter for heat. The unit is pretty close to silent and did a fantastic job warming up and maintaining temperature in a two-car garage. One thing I was amazed at is although this is rated for 15°, it still performed well in extremely cold conditions.”
Customer Review: “This is an excellent Mini. Installed in my shed and had it 80 degrees in a matter of minutes. Installation is fairly simple and took about 1.5 hrs. A vacuum pump, gauge set, and some hand tools were required. There is plenty of copper tube and wire length. We cut about 3 ft of tubing off and flared the lines. No issues at all in installation. I was very surprised how quiet it is. The inside unit oscillates up and down distributing heat evenly in the room. Highly recommend this mini.”
Customer Review: “Whisper quiet and chills the room nicely. Love the ability to schedule when it turns on and off. Only 4 stars instead of 5 because it turns out mine had a bad wireless adapter, but it took a few weeks and tons of phone calls to get anyone to help me.”
