Bosch 8733980450 27K 2-zone Mini Split Kit 12K 18K

Product Description

The BOSCH 8733980450 is a complete 2-zone mini split system kit rated at 27,000 BTU/h, designed for residential and light commercial ductless cooling and heating applications. This kit bundles a single outdoor unit with two indoor air handlers and pre-measured line sets, giving HVAC technicians everything needed to complete a multi-zone installation in a single order. The kit ships as a matched-component assembly, which helps ensure refrigerant circuit compatibility across all zones from the start of commissioning.

This system is suited for residential multi-room applications where individual zone control is required without ductwork. Typical installations include single-family homes, additions, garages, or light commercial spaces where two separate zones need independent temperature management. The 27,000 BTU/h total capacity is split across a 12,000 BTU/h indoor unit and an 18,000 BTU/h indoor unit, allowing flexibility in room sizing and load matching. The included 25-foot line sets cover standard through-wall or overhead runs in most residential scenarios.
