The Cooper & Hunter 28,000 BTU Dual Zone Mini Split Air Conditioner offers robust cooling and heating capabilities with its 28,000 BTUs and dual zone system (9,000 BTU and 18,000 BTU units). The high SEER ratings of 23.80 and 24.6 SEER2 indicate excellent energy efficiency, which can help save on electricity bills. Its impressive noise level of 25 dB ensures quiet operation, making it a suitable choice for bedrooms and living spaces.

The inclusion of smart technology allows for convenient control via a smartphone app, adding to its user-friendly features. However, the unit requires professional installation, which could be a drawback for those looking for a DIY option. Additionally, its substantial weight and the need for freight delivery might be inconvenient for some users. On the plus side, it is equipped with a comprehensive installation kit and U.S.-based support is available for assistance.

The heating capability works in temperatures as low as -13°F, making it versatile for various climates. Potential buyers should consider the initial installation costs and logistics involved in setting up this system.

The DELLA 18K BTU Two-Zone Mini Split AC and Heat Pump is a solid choice for cooling and heating spaces up to 600 square feet. With an 18,000 BTU capacity and a strong 22 SEER2 rating, it delivers efficient performance that can save you about 57% in power usage compared to less advanced models. It also works reliably in cold climates down to -13°F, thanks to its heating element preventing ice buildup on the outdoor unit. This system includes two indoor units suitable for cooling or heating two rooms or zones, making it a versatile option for homes or small commercial spaces.

Smart features stand out here, including WiFi connectivity with Alexa and Google Home voice control, plus a geo-location function that adjusts temperatures automatically based on your presence, which is great for saving energy. The remote control and app add convenience for day-to-day use. Maintenance is straightforward, needing only seasonal cleaning of reusable filters, which keeps running costs and effort low.

Installation requires professional help due to the complexity and refrigerant handling, and the included 16.4-foot installation kit fits many setups but might need adjustments for longer runs. While the display shows a self-cleaning function, this feature is not available, so filter cleaning must be managed manually. Mini-splits typically operate quietly, contributing to a comfortable environment. For those looking for an energy-efficient, smart-controlled two-zone system with solid heating capabilities and easy maintenance, this DELLA model is a good option, provided professional installation and manual upkeep of filters are acceptable.

The Della 36K BTU Dual Zone Mini-Split Air Conditioner is a solid choice for those looking to cool or heat multiple rooms efficiently. With a total output of 36,000 BTU and a Seasonal Energy Efficiency Ratio (SEER) of 19, it offers good energy savings compared to traditional systems. The capacity to cover up to 2,050 square feet makes it suitable for larger spaces, and the inclusion of two separate indoor units allows for individual temperature control in different rooms, which adds to its versatility.

One of the standout features of this unit is its advanced smart technology. It is compatible with Alexa and WiFi, allowing for easy remote control and management via your smartphone. Additionally, the unit includes multiple modes such as turbo, sleep, and eco modes, enhancing user experience and comfort.

Installation requires professional help, which can add to the initial cost and effort needed to set it up. The lack of a self-cleaning function, despite the button being present, might also be a disappointment for some users. Additionally, while the noise level at 51 dB is relatively quiet for an air conditioner, those particularly sensitive to sound may wish for a quieter operation.
