Detailed Specifications & Documentation

Designed Comfort for Four Spaces

The MRCOOL Olympus 4-Zone Mini Split System is designed to deliver coordinated, professional-grade comfort across multiple areas of your home. By connecting four indoor air handlers to a single outdoor condenser, the system provides balanced heating and cooling with a clean, unified installation approach.

Ideal for whole-home applications or larger living spaces, Olympus creates a cohesive system where each room operates independently while contributing to an overall comfort strategy.

Whole-Home Zoning Without Ductwork

Olympus allows you to condition multiple rooms independently without the limitations of traditional ducted systems. Each zone can be adjusted based on usage, occupancy, or preference, helping reduce energy waste while maintaining consistent comfort throughout the home.

This makes it an ideal solution for multi-room layouts, additions, and homes with varying heating and cooling needs.

Engineered for Balanced Performance

At the core of the Olympus system is an inverter-driven compressor that continuously adjusts output to match demand across all four zones. Instead of cycling on and off, it modulates performance to maintain stable temperatures and efficient operation.

The result is quieter performance, smoother comfort transitions, and consistent conditioning across every connected space.

Installation Built for Long-Term Reliability

Olympus systems are designed for professional installation, ensuring proper system layout, refrigerant management, and optimized performance. This approach allows the system to be tailored to your home’s specific design and usage patterns.

The result is a clean installation and dependable operation over time.

Flexible System Design

With multiple indoor unit styles and capacity options, Olympus adapts to a wide range of home layouts — from open living areas to individual rooms.

The system scales cleanly as more zones are added, maintaining a streamlined exterior footprint while expanding interior comfort coverage.

Smart Control, Room by Room

Each zone can be controlled independently using included remotes or compatible smart control options. Adjust temperature, fan speed, and operating modes for each room without affecting the others.

This level of control allows you to tailor comfort precisely to how each space is used throughout the day.
