Detailed Specifications & Documentation

Expanded Zoning for Larger Living Spaces

The MRCOOL DIY Multi-Zone 5 Zone System is designed for homeowners who need to manage comfort across a wider portion of the home. With five indoor units connected to one outdoor condenser, this system creates a structured and scalable approach to multi-room heating and cooling.

It is ideal for homes where comfort needs extend across multiple bedrooms, shared areas, and additional living spaces.

Designed for Broader Coverage

A 5 zone system allows homeowners to bring independent comfort control to a larger number of rooms without relying on a one-size-fits-all approach. Each zone can be adjusted based on how the space is used, helping create a more efficient and comfortable overall environment.

DIY-Friendly Multi-Zone Platform

The MRCOOL DIY system simplifies the path to ductless zoning. With pre-charged QuickConnect line sets in compatible configurations, installation is more approachable than many traditional multi-zone systems.

Flexible Configuration Options

This system supports a range of indoor unit combinations to match different room sizes and layouts. Depending on configuration, buyers may be able to choose between wall-mounted and cassette-style indoor units.

Important Selection Note

This is a configurable parent product organized by zone count. Final condenser selection, indoor unit sizing, and included components depend on the selected options.
