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.
This air handler integrates into your ductwork for seamless, hidden comfort. Whether for a spacious living area, open-plan zone, or light commercial space, the Olympus 18K handles the job with modern efficiency and minimal noise.
As part of the Olympus professional series, this air handler must be installed by a licensed HVAC technician. Pre-charging, evacuation and pressure testing ensures the system’s refrigerant integrity, energy efficiency and warranty eligibility.
