Bosch 8733980453 Mini Split Kit 18000 Btu 2 Zone

Product Description

The BOSCH 8733980453 is a complete 2-zone mini split system kit rated at 18000 BTU, designed for residential and light commercial zoned heating and cooling applications. This kit bundles the outdoor unit, two indoor air handlers, and two pre-charged line sets into a single package, reducing procurement time and component mismatches. The kit ships at a net weight of 202 pounds, making crane or team lift staging necessary on most installs. Licensed HVAC technicians typically handle installation and commissioning of this type of multi-zone system.

This kit is suited for applications requiring independent temperature control in two separate zones, such as multi-room residential additions, garage conversions, or small commercial spaces. The two indoor units are rated at 9000 BTU and 12000 BTU respectively, allowing capacity to be matched to room load. Each zone ships with a 25-foot line set, providing standard reach for most wall-penetration installations. The outdoor unit, both indoor heads, and both line sets are included in the kit as listed below.
