Della’s dual-zone mini splits are designed for homeowners who want zone-specific cooling without the ductwork. This 28,000 BTU setup pairs a 12,000 BTU unit with an 18,000 BTU unit, giving you independent temperature control in two separate rooms or zones. The 20 SEER2 rating and DC inverter compressor deliver real energy savings—up to 30% less power draw compared to a standard unit. That matters if you’re cooling a large living area and a bedroom on different schedules.

The heat pump works down to -13°F, so this system pulls double duty as a heater in colder months. Noise stays at 50 decibels, which is quiet enough for a bedroom or home office. The pre-charged lineset simplifies installation, though you’ll still want a professional for the electrical and vacuum work. One honest note: the self-cleaning function listed on the display doesn’t actually run. Press the button, and nothing happens. It’s a minor UI quirk, but worth knowing if you expect automated coil maintenance.

For a two-zone system at this price point, the efficiency and low-temperature heating are strong selling points. The 2.25-ton capacity handles spaces up to roughly 1,500 square feet combined, depending on insulation and layout. If you need separate climates for two rooms without the expense of a full multi-zone system, this is a practical, well-specced option.
