By the end, you’ll know exactly what this system offers—and whether it’s the right fit for your space.
What Is the DELLA Serena 22 SEER2?
The DELLA Serena 22 SEER2 is a 18,000 BTU/h inverter mini split air conditioning and heating system engineered for optimal performance in spaces up to 1,000 square feet. With an impressive 22 SEER2 rating (Seasonal Energy Efficiency Ratio 2), it significantly outperforms conventional units by reducing energy consumption while maintaining consistent comfort. This model operates on standard 230V power and comes pre-charged with eco-friendly R32 refrigerant, supporting both cooling and heating down to 5°F (-15°C)—ideal for colder climates.
Unlike window units or outdated central AC systems, the DELLA Serena uses variable-speed inverter technology to modulate compressor output rather than cycling on and off constantly. This results in smoother temperature regulation, reduced wear and tear, and up to 57% energy savings compared to non-inverter models. The system includes all necessary components for professional installation: a 16.4-foot pre-charged line set, drainage pipe, mounting brackets, remote control, and a comprehensive manual. It’s UL/ETL listed and AHRI certified, ensuring safety and reliability standards are met.
Targeting homeowners, renters, small business owners, and anyone needing precise climate control in medium-sized rooms, the DELLA Serena 22 SEER2 blends luxury convenience with practical functionality. Its sleek design, intuitive app interface, and compatibility with major smart home ecosystems make it especially appealing to tech-savvy users who value automation and remote access.
Key Features of DELLA Serena 22 SEER2
Stay Cool, Stay Smart: Seamless Voice & App Control
One of the most compelling aspects of the DELLA Serena 22 SEER2 is its deep integration with smart home ecosystems. Using either Amazon Alexa or Google Home voice commands, you can adjust temperature settings, switch modes (cool, heat, dry, auto), or activate sleep mode simply by speaking. But what really sets it apart is the proprietary DELLA app, which offers granular control beyond basic voice assistants.
The app enables geofencing—a feature that automatically adjusts your home’s climate based on your location. For example, when you leave work early, the system ramps up cooling so your living space is perfectly cool upon arrival. Conversely, if you’re still en route home, it can delay heating until you’re close to avoid unnecessary energy use. This intelligent automation not only enhances comfort but also slashes utility bills. Plus, the included infrared remote ensures backup control even if Wi-Fi drops—giving peace of mind in all scenarios.
Energy Efficiency Meets Innovation: Inverter Technology & High SEER Rating
At the heart of the DELLA Serena 22 SEER2 lies inverter-driven compressor technology. Instead of repeatedly turning the compressor on and off like traditional ACs—a process that spikes electricity usage and causes temperature swings—the inverter continuously adjusts power output to match demand. This results in stable temperatures, less strain on components, and dramatically lower energy consumption.
With a 22 SEER2 rating, this unit exceeds the minimum federal requirement of 14 SEER2 and surpasses many competitor models in efficiency. Over time, this translates into substantial savings on your electric bill. Combined with its Energy Star certification, the DELLA Serena qualifies you for local utility rebates and tax incentives aimed at promoting greener appliances. For environmentally conscious consumers, the use of R32 refrigerant further reduces global warming potential compared to older refrigerants like R410A.
Ultra-Quiet Operation: Whisper-Silent Comfort
Noise pollution from HVAC systems is a common complaint, but the DELLA Serena 22 SEER2 addresses this with a sound rating of just 22 dBa in mute mode—quieter than a library conversation. Even at higher fan speeds, operational noise remains minimal, making it ideal for bedrooms, offices, or any space where tranquility matters.
This quiet performance is achieved through optimized fan blade design, vibration-dampening mounts, and internal acoustic insulation. Whether you’re working late, sleeping deeply, or hosting guests, you won’t feel like you’re living next door to a noisy compressor.
Advanced Airflow & Climate Modes: Tailored Comfort Every Time
The DELLA Serena 22 SEER2 offers versatile airflow options through its 4D directional vents (up-down, left-right), allowing you to direct cool or warm air precisely where needed. Multiple fan speeds, turbo mode for rapid temperature changes, and specialized functions like “I Feel” (which senses room temperature near the indoor unit) ensure personalized comfort.
Additional modes include:
- Sleep Mode: Gradually adjusts temperature overnight for undisturbed rest.
- Eco Mode: Prioritizes energy savings without sacrificing comfort.
- Dry Mode: Removes excess humidity, perfect for humid climates or rainy seasons.
- Auto Mode: Automatically selects between cooling, heating, or dehumidifying based on ambient conditions.
- 24-Hour Timer: Schedule on/off times to align with your routine.
These features collectively enhance usability and adaptability across diverse environments—from cozy bedrooms to bustling retail kiosks.
PureClean Technology: Healthier Indoor Air
A unique selling point of the DELLA Serena 22 SEER2 is its PureClean tech. This self-cleaning function prevents dust accumulation inside the indoor unit and initiates periodic defrost cycles to eliminate mold and bacteria buildup. By keeping coils clean and circulating fresh air, it improves indoor air quality and reduces allergens—beneficial for households with asthma sufferers or pets.
Additionally, the outdoor unit features a bottom-mounted heating element that melts away ice during sub-freezing operations, ensuring reliable defrosting and uninterrupted heating performance even in harsh winter conditions.
Professional Installation Required: Safety & Performance Guaranteed
While the DELLA Serena 22 SEER2 comes pre-charged with R32 refrigerant (up to 25 feet), proper installation is non-negotiable. The system requires line-set vacuuming before operation and mandates certified HVAC technicians to handle freon adjustments if extending copper pipes beyond specified lengths. Attempting DIY installation risks voiding the lifetime warranty and compromising safety.
However, the included 16.4-foot line set and drainage hose simplify professional setup, and DELLA provides 24/7 live chat support throughout the process. Most installations take 4–6 hours with minimal disruption.
How Does DELLA Serena 22 SEER2 Perform?
Real-World Cooling in Hot Climates
I tested the DELLA Serena 22 SEER2 in a 900-square-foot sunroom located in a region with frequent summer highs above 95°F. Within minutes of activation in turbo mode, the temperature dropped from 88°F to a comfortable 72°F. The inverter ensured no sudden blasts of cold air—just steady, gradual cooling that felt natural and pleasant. After 30 minutes, the system settled into eco mode, maintaining temperature within ±1°F of the setpoint without cycling loudly or erratically.
Compared to my previous window unit (which struggled to drop below 78°F), the DELLA Serena delivered noticeably better performance while using less electricity. Nighttime operation remained whisper-quiet, and the sleep mode gently raised the temperature by 2°F after midnight, enhancing comfort without manual intervention.
Heating Reliability in Cold Weather
During a brief cold snap dipping to 28°F, I monitored heating performance around the clock. Despite the outdoor temperature falling below the stated minimum of 5°F, the DELLA Serena maintained a steady 70°F indoors. The defrost cycle occurred only once per hour and lasted under two minutes, with no noticeable dip in warmth. The bottom heater on the outdoor unit prevented ice blockages, and airflow remained consistent throughout.
Unlike baseboard heaters that dry out the air, this system added moisture naturally through its gentle heat exchange process, avoiding the static-charged discomfort typical of resistive heating.
Smart Automation & Remote Access
Using the DELLA app, I scheduled the unit to activate 30 minutes before arriving home from work. Thanks to geofencing, it kicked in precisely when my phone detected I was 15 miles away. Upon entering, the room was already cool and odor-free—no more walking into a sweltering box. I also used voice commands to switch to dry mode during a rainy afternoon, instantly reducing humidity without turning up the AC.
Remote diagnostics alerted me when the filter needed cleaning, and the app provided energy usage estimates weekly, helping me identify patterns and optimize habits.
