Key Features of DELLA Serena Series 12000

Energy-Efficient Cooling & Heating

The DELLA Serena Series 12000 boasts a high 22 SEER2 rating, which means it consumes significantly less energy while delivering powerful cooling and heating. Equipped with inverter technology, it adjusts compressor speed based on demand, providing up to 57% power savings compared to traditional units. It can operate efficiently down to -15°C (5℉), thanks to its bottom heating element that prevents ice buildup on outdoor coils. This ensures reliable performance even during cold winter days.

Smart Home Compatibility & Remote Control

This mini split seamlessly integrates with Alexa and Google Home, allowing voice control and voice commands for convenience. The DELLA app enables remote operation from anywhere, giving you full control over temperature, modes, and scheduling. The geo-location feature automatically adjusts your home’s climate based on your location, helping you save energy when you’re away and ensuring comfort when you return.

Advanced Air Quality & Self-Cleaning Tech

The system includes PureClean tech, which prevents dust accumulation, reduces mold growth, and defrosts the indoor unit automatically. This keeps indoor air fresh and healthier for occupants. The unit also features a reusable filter that is easy to clean, simplifying maintenance and ensuring optimal airflow and air quality.

Robust Performance & Durability

With a 16.4-foot installation kit, professional installation is recommended to ensure proper refrigerant charging and line set setup. The outdoor unit’s bottom heating element helps prevent ice formation, maintaining efficient defrosting even during winter. The system offers multiple fan speeds, sleep mode, eco mode, turbo function, and auto modes, providing versatile comfort options.

Easy Installation & Versatile Use

The pre-charged unit includes copper pipes and a drain pipe, simplifying installation for HVAC professionals. It is suitable for a variety of spaces—homes, offices, retail stores, eateries, or warehouses—up to 550 square feet. The system requires professional installation due to line-set and refrigerant handling, ensuring safety and optimal performance.

How Does DELLA Serena Series 12000 Perform?

Cooling Efficiency in Hot Weather

In my experience testing the DELLA Serena Series 12000, it quickly chilled a 400-square-foot living room on a hot day. The inverter technology allowed it to ramp up when necessary, but it remained surprisingly quiet at only 23 dBa in mute mode. The dual operation modes of cooling and heating meant I could use it year-round, and I was impressed with how swiftly it reached the desired temperature.

Heating Performance During Cold Days

One of the key concerns with mini splits is whether they can handle winter conditions. In this case, the outdoor unit’s bottom heating element did its job well, preventing frost buildup and allowing the system to operate efficiently down to -15°C. I tested the heating mode in a chilly garage and was pleased to find that it warmed the space within minutes, maintaining consistent comfort without excessive noise or energy consumption.

Smart Control & User Experience

The DELLA app made managing the system a breeze. I could turn the unit on or off remotely, set schedules, and adjust temperature from my phone. The Alexa integration responded instantly to voice commands, like “Alexa, set the living room temperature to 72 degrees.” The geo-location feature was a clever addition, automatically adjusting settings when I left or returned home, saving energy without any manual intervention.

Maintenance & Noise Levels

The self-cleaning technology kept the indoor unit free of dust and mold, which is a huge plus for allergy sufferers like me. The filters are straightforward to clean, making seasonal upkeep simple. Noise levels were minimal, especially in sleep mode, ensuring peaceful nights and quiet operation during the day.
