Description

This 34,000 BTU ducted central AC system provides efficient cooling and heating with R-454B refrigerant and 19 SEER2 performance powered by inverter technology. Its heat pump operates in temperatures as low as -5°F, offering dependable comfort through colder months.

A three-cylinder, dual-stage inverter rotary compressor adjusts output to maintain steady temperatures across large rooms and multi-room layouts. With support for RS-485 and 24V control, the system connects smoothly with a wide range of central AC configurations. High static pressure (200 Pa) and 7 adjustable fan speeds deliver strong, even airflow for multi-room or multi-floor spaces.

The system supports optional upgrades, including a wired controller for fixed-location control and 5kW, 10kW, 15KW, or 20kW heat kit options for additional heating capacity in extremely cold climates. These add-ons offer more flexibility based on your installation needs and regional weather.

The indoor unit supports both vertical and horizontal installation to fit a variety of layouts. Note: Professional installation is required; not suitable for DIY. Electrical specs: Indoor unit max fuse 15A, outdoor unit max fuse 35A.

Customer photo review of DELLA 34,000 BTU 19 SEER2 Ducted Central Air Conditioner with Air Handler

The DELLA 34,000 BTU central AC looks like a solid option for a home cooling system. I like that it comes with both the outdoor unit and the air handler. The 19 SEER2 efficiency rating is also a nice feature, especially with electricity costs these days. The equipment has a simple design and seems like a practical choice for replacing an older AC system. Overall, it offers a good combination of cooling capacity and efficiency.
