Who it fits

Key specs explained for Della

Cooling Capacity: 27,000 BTU

This total output covers up to 1,250 square feet. You get one 9,000 BTU unit and two 12,000 BTU units for balanced temperature control. Compare this to single-zone models if you need to manage multiple rooms. Higher BTU ensures faster cooling in hot weather, while lower outputs prevent overcooling in smaller zones.

Efficiency Rating: 22 SEER2

SEER2 measures seasonal energy efficiency under updated federal testing standards. A 22 rating indicates high performance, meaning lower electricity usage for the same cooling output. Compare this to older 13 or 15 SEER models to see potential power savings. Higher numbers generally translate to reduced operating costs over the system's lifetime.

Number of Zones: 3 Zone

This tri-zone setup allows independent temperature control for three distinct areas. You can cool one room while heating another, or turn off unused zones entirely. This flexibility suits multi-story homes or open layouts with separate thermal zones. Compare this to single-zone systems that only control one space with a single thermostat.

Smart Connectivity: DELLA App, Alexa

You can control the unit via the Della App or voice commands through Alexa. This allows remote adjustments from your phone or hands-free operation. Compare this to basic remote-only models that require physical proximity. Smart features enable scheduling and geolocation triggers to pre-condition your home before you arrive.

Design and Build Details

The indoor unit measures 27.5 inches wide, 19.3 inches long, and 7.87 inches tall. It weighs 33.1 pounds. The listing describes a white finish. This compact, rectangular casing is designed for concealed installation in ceilings or attics. You do not see the main unit in the living space. The design hides the machinery behind drywall or ceiling panels. This creates a clean, seamless look for your home or office. The system includes three separate air handlers. You get one 9,000 BTU unit and two 12,000 BTU units. These smaller handlers distribute air into specific zones. The low profile fits into tight attic or crawl space areas. You need to check your available space before buying.

Control options are built into the package. You receive a dedicated thermostat and a handheld remote. The listing also confirms support for the DELLA App and Alexa. You can adjust temperatures remotely from your phone. Smart features include geolocation, which starts the system when you approach home. This adds convenience without extra hardware. The unit operates quietly at 32 dB. You will not hear the main compressor indoors. The design prioritizes hidden integration. You get flexible coverage for up to 1,250 square feet. Two return air positions allow for different duct layouts. This helps you fit the unit into various room shapes. Professional installation is required. You cannot install this yourself. The system uses eco-friendly R454B refrigerant. It also includes a built-in condensate pump. This pump moves water away from the unit automatically. You do not need gravity drainage. This makes installation easier in tight spaces. The design focuses on efficiency and quiet operation. You get reliable performance in multiple rooms.

Setup and everyday use

You need professional installation for this system. It is not a DIY project. The unit requires a 208-230V power connection. You must install a 30A fuse for safety. The package includes three 25-foot copper line sets. These connect the outdoor compressor to the three indoor handlers. If your line sets exceed 25 feet, you must adjust the refrigerant charge. The system uses R454B refrigerant. It also includes a built-in condensate pump. This pump helps manage water removal during operation. You can choose from two return air positions. This gives you flexibility for your ductwork layout. The unit supports 0.4 inches of water column static pressure. This allows for complex duct designs in multi-story homes. For daily use, you control the temperature via the included thermostat or remote. You can also use the Della App or Alexa. The app supports geolocation. This feature starts the system before you arrive home. You can set temperatures between 60°F and 90°F. The fan has seven speeds. This lets you adjust airflow from 360 CFM.

The concealed design keeps the unit hidden in your ceiling or attic. This setup provides consistent comfort for up to 1,250 square feet.

Before You Buy This Unit

You need a professional installer for this unit. The system is not designed for DIY setup. You must verify your electrical panel supports 208-230V power. A 30A fuse is required for safe operation.

You may need additional refrigerant adjustment if your lines exceed 25 feet. The Della app and Alexa compatibility allow remote control. You can also use the included thermostat. Regular maintenance involves cleaning the filters and checking the condensate pump. This tri-zone model fits well alongside other multi-zone options.
