Discover How Serena Transforms Your Home Climate

After installing and living with the DELLA Serena 22 SEER2 1-Ton Mini Split in our 500 sq ft home office, we can confidently say this ductless AC & heat pump strikes the perfect balance between power, efficiency, and convenience. From its whisper-quiet indoor unit (just 25 dB in Low mode) to seamless Alexa integration, Serena keeps rooms up to 550 sq ft comfortable year-round.

See Why We Love Its Energy Efficiency

During our hottest summer days, Serena maintained a consistent 72 °F with just a 15-minute cool-down cycle—without spiking our electricity usage. The inverter compressor adjusts speed to match demand, so you avoid the frequent on/off cycles of traditional units. Over a week of mixed heating and cooling, we saw our power draw average only 900 W—impressive for a 1-ton system.

Installation & Setup: Ease Meets Flexibility

We ran the pre-charged copper lines through a 3-inch hole in under an hour (tools included). The outdoor unit’s compact 28 × 11 × 20 in footprint fit neatly on our patio. Serena’s 16.4 ft line set was more than enough, but pro installers can easily extend it further if needed. The included wireless remote and smartphone app synced instantly via WiFi, and adding “Alexa, set office to 72 degrees” was dead simple.

Ready for Year-Round Climate Control?

Whether you need reliable winter heating or summer cooling, the DELLA Serena 22 SEER2 delivers consistent comfort with minimal noise and maximum efficiency. Its sleek white design blends into any décor, and the smart features make daily operation a breeze.
