DELLA 28K BTU Mini Split
The market for dual-zone mini splits is crowded with complex, high-cost options, but the DELLA 28K BTU system stands out by delivering substantial multi-room capacity and modern smart features at a notably competitive price point for its class.
Where It Excels
- This system offers a significantly lower upfront cost per BTU compared to premium s like Mitsubishi or Daikin, making high-capacity zoning more accessible.
- Its inclusion of Wi-Fi and Alexa compatibility as standard provides a smart home advantage that many competitors in this price bracket treat as a costly add-on.
- The pre-charged linesets and included installation kits simplify the initial setup process for HVAC professionals.
Where It Lags
- It has fewer advanced diagnostic and service features than established s like Fujitsu, which can make long-term maintenance slightly more involved for technicians.
- The system’s performance in heating mode diminishes below 5°F, whereas units from s like Gree often maintain better output at lower temperatures than DELLA’s -13°F specification.
- A notable functional omission is the self-cleaning feature; while the option appears on the remote, it is non-operational, a detail some users may find misleading.
Positioned at #5 in our ranking, the DELLA 28K BTU dual-zone mini split is a compelling choice. Pick this if maximizing cooling and heating capacity for two large rooms on a strict budget is your primary goal, and you value smart connectivity. However, for extreme cold-climate heating performance or -centric reliability with extensive dealer support, investing in a higher-ranked model is advisable.
