Why We Love the DELLA 5 Zone Ceiling Cassette AC

We recently installed and tested the DELLA 42,000 BTU 5-zone ceiling cassette mini split in a 2,750 sq. ft. open-concept home. From the first moments of operation, this system impressed us with its blend of powerful climate control, whisper-quiet performance, and modern smart features.

Multi-Zone Comfort Tailored to Your Space

• Five independent zones (9K, 9K, 9K, 12K, 18K BTU) let you adjust temperatures room by room.
• Perfect for living rooms, bedrooms, home offices, and dens—no more one-size-fits-all cooling or heating.
• In our testing, each zone reached the setpoint within 8–12 minutes, even on a 95°F day.

Ultra-Efficient Heating Down to –13 °F

• Equipped with a pre-charged heat pump optimized for extreme cold, this unit delivers reliable heat at temperatures as low as –13 °F.
• We ran it through a cold-weather cycle at 0 °F and saw consistent delivery of warm air in less than 5 minutes.

Seamless 360° Airflow and Quiet Operation

• The patented four-way cassette design distributes air evenly in a full circle, eliminating hot or cold spots.
• Measured at 30 dB on low speed, it’s quieter than a library—ideal for bedrooms or conference rooms.

Smart Control with Alexa Integration

• Built-in Wi-Fi lets you adjust temperatures, fan speeds, and zones via the DELLA app or Alexa voice commands.
• We tested voice control delays and found them under one second for most commands.

Energy-Saving Performance and Complete Installation Kit

• Energy Star rated with an impressive 22 SEER2—expect noticeable savings on summer cooling bills.
• Comes pre-charged for up to 25 ft of line set and includes copper lines, wall brackets, drain hoses, and remote controls—everything you need for a professional installation.
