MRCOOL® Olympus 12,000 BTU (1 Ton) Ductless Mini Split Ceiling Cassette with Panel 230 V/60 Hz | CASSETTE12HP-230C-P-O
Olympus = Best. The MRCOOL® Olympus 12,000 BTU (1 Ton) Recessed 4-Way Ceiling Cassette delivers quiet, high-efficiency heating and cooling with a clean, flush-mount ceiling design. Ideal for single rooms and zones up to ~550 sq. ft., this compact cassette maximizes floor and wall space while providing premium, evenly distributed comfort.
Professional Install Required: Olympus indoor cassettes are part of a traditional (non-DIY) mini split system. Refrigerant lines must be nitrogen pressure-tested and vacuumed before releasing charge from the outdoor condenser to ensure performance, efficiency, and warranty coverage.
