MRCOOL® Olympus 18,000 BTU (1.5 Ton) Ducted Mini Split Air Handler 230 V/60 Hz | DUCT-18HP-230B-O
The MRCOOL® Olympus Series stands at the peak of professional-grade comfort and performance. The Olympus 18,000 BTU (1.5 Ton) Ducted Mini Split Air Handler is designed for larger zones and whole-room ducted applications, delivering premium heating and cooling with quiet precision.
Important Note: Olympus models are built for traditional installation and are NOT pre-charged. Professional HVAC installation is required — the system must be nitrogen evacuated, vacuumed and pressure-tested before releasing the refrigerant charge from the outdoor condenser to validate warranty coverage and ensure optimal performance.
