Product Description

The BOSCH 8733980409 is a Generation 4 single-zone mini-split system rated at 18,000 BTU/h, designed for maximum-performance residential and light-commercial heating and cooling applications. Operating on 230 volts, this system achieves a SEER2 rating of 21.4 and an EER2 of 12.5, placing it firmly in the high-efficiency tier. The heating performance is rated at HSPF2 11.0 with a COP of 3.26 at 47 degrees F. The kit ships as a complete assembly including an indoor unit, outdoor unit, and a 25-foot line set, making it a streamlined solution for new installations. It carries Energy Star certification. Licensed HVAC technicians handle installation and system commissioning.

This system is suited for single-zone residential rooms, additions, sunrooms, garages, and small commercial spaces where a ducted system is impractical or not present. The 25-foot pre-measured line set supports straightforward wall-penetration installations where the outdoor unit can be positioned nearby. The Generation 4 platform is designed for high-efficiency operation across a broad outdoor temperature range, making it appropriate for both cooling-dominant and heating-dominant climates. The complete kit format reduces sourcing steps for installing contractors.
