Why You Might Need Della Multi Zone Mini Split
Homes with multiple rooms often struggle with uneven temperatures. Maybe the living room cools too much while bedrooms stay warm. You want personal control of each space without running multiple standalone units. Perhaps you’re seeking a quieter air conditioner that won’t disrupt your daily routines or sleep. This system targets those challenges with four indoor handlers, letting you decide exactly how warm or cool each room gets. Additionally, those living in regions with high energy costs appreciate efficient technology that reduces electrical consumption while maintaining comfort year-round.
First Impressions: What to Expect
Unboxing the Della 35K BTU multi-zone unit reveals a complete kit including four indoor air handlers, one outdoor condenser, line set copper pipes, drain pipes, and installation kits. Each indoor unit is roughly sized to fit typical room dimensions (three 9K BTU handlers and one 18K BTU handler). The components feel solid yet lightweight enough for professional installation.
You’ll notice a modern, sleek design for the indoor units with a neutral white finish that blends well into most interiors. Installation requires wiring to a 208-230V power source and connection of refrigerant lines, which comes pre-charged but requires adjustment if you alter line length. The system is ETL listed and AHRI certified, affirming safety and compliance.

Della 35K BTU Multi Zone Mini Split Specs
Design & Build Quality
The Della multi-zone mini split system shows a thoughtful balance of robust construction and ease of integration. The indoor air handlers boast a compact, rectangular design that fits discreetly on walls without overwhelming room aesthetics. Each unit includes a dedicated remote and offers WiFi plus Alexa control, so you have flexibility whether at home or away.
Installation parts like copper refrigerant tubing and drain pipes are standard sizes and included for convenience, easing your preparation for professional setup. Several users commented appreciatively on the quiet operation — one noted, “Once installed, I barely hear the indoor units working, which is perfect for my home office and bedrooms.” The outdoor condenser has a durable metal casing that feels weather-resistant.
The only minor drawback is the absence of a true self-cleaning function, despite the option appearing on the remote. This may require you to schedule periodic maintenance to keep the system at peak performance.
Real-World Performance
In real-world use, the Della 35K BTU unit delivers on its promise of steady, efficient cooling and heating across multiple rooms. For example, a homeowner with a 4-room setup found the individual temperature control transformative. “I can keep the living room cooler for the kids while leaving the master bedroom warmer for myself,” they added. This precise zoning is especially helpful in households with different thermal preferences.
The inverter technology adjusts compressor speed dynamically, avoiding the constant on-off cycling typical of older systems. This results in more stable indoor temperatures and smoother operation while saving energy. The AC is also capable of functioning in temperatures as low as 5°F, making it a reliable choice even in colder regions.
Some users reported slight delays when all zones demand maximum output simultaneously due to the outdoor unit’s total capacity being 35K BTU, less than the combined indoor units. For typical home use, this isn’t a hindrance but is worth noting for larger systems or heavy simultaneous load.

What Makes It Stand Out?
Compared to similar multi-zone mini splits from brands like Mitsubishi and Pioneer, the Della model distinguishes itself with its Alexa and WiFi compatibility as a standard feature. This allows users to integrate the air conditioner into their existing smart home ecosystems without additional hubs or accessories.
While Mitsubishi offers a longer track record and Pioneer has strong customer support, Della provides a balance of advanced energy-saving inverter tech plus modern smart functions at an accessible installation scale. The pre-charged refrigerant setup saves you from the complexity of refrigerant filling during installation, which is a convenience not all competitors offer.
However, unlike some higher-end models, Della lacks the self-cleaning feature that might appeal to those wanting reduced maintenance demands. It’s also designed with moderate total capacity, so for very large homes or consistent full-power demand in all zones, you might consider additional or larger systems.
Strengths vs. Trade-Offs
| ✅ Strengths | ❌ Trade-Offs |
|---|---|
| Energy efficient DC inverter technology saves power | Self-cleaning button does not function, requiring manual upkeep |
| 4 indoor units with independent controllers for zones | Combined indoor BTU capacity slightly exceeds outdoor unit output, limiting max simultaneous power |
| Alexa and WiFi compatible for smart home integration | Line-set adjustments require professional vacuuming and refrigerant charge tweaks |
| Ultra-quiet operation at 43 dBA suitable for bedrooms | Not designed for multi-system scaling if all zones demand high power simultaneously |
| Heat pump functionality supports cold climates down to -13℉ | Installation complexity may require a professional service |
| Pre-charged refrigerant reduces setup hassle |

Who Is It For?
This multi-zone mini split air conditioner is ideal if you:
- Own a mid-sized home with multiple rooms where individualized climate control is essential. Families with differing temperature preferences in bedrooms, living rooms, or home offices will benefit greatly.
- Value smart home technology integration and want Alexa and WiFi compatibility out of the box.
