Description
MRCOOL Olympus 12K BTU 1 Ton Ducted Air Handler ONLY — DUCT-12HP-230B-O
Premium Ceiling-Integrated Ducted Mini Split Indoor Unit
The MRCOOL Olympus 12K BTU 1 Ton Ducted Air Handler (DUCT-12HP-230B-O) is a professional-grade ceiling-integrated indoor unit designed for ducted mini split installations. As part of the Olympus series — MRCOOL's highest-tier ductless line — this ducted air handler delivers powerful, efficient heating and cooling for spaces up to 500 square feet while maintaining a completely concealed, flush-ceiling appearance.
The ducted design makes it ideal for applications where a wall-mounted unit is not desirable — such as open-plan living areas, commercial spaces, or renovations where ductwork can be routed through ceilings. Factory pre-charged with R-454B refrigerant, this unit meets current environmental standards and pairs with any compatible Olympus condenser for a complete, high-performance split system.
