Description
MRCOOL DIY Hybrid Central Split System 2-Zone 55k BTU Condenser with 24K Ducted Air Handler and 36K Wall Mounted Air Handler
This MRCOOL DIY Hybrid Central Split System is built for projects where one solution needs to do two jobs: deliver concealed, ducted comfort to a larger central area while adding independent ductless control to a separate room or zone. It pairs a 55K MRCOOL DIY multi-zone condenser with a 24K Hybrid™ Split System Ducted DIY Air Handler and a 36K wall mounted air handler.
The result is a flexible hybrid mini split system that can replace or supplement traditional central HVAC without giving up room-by-room comfort. Use the ducted air handler for a main living area, suite, or grouped room layout, then use the wall mounted air handler for a bedroom, office, addition, bonus room, or any space that benefits from its own temperature control.
Why this system works
- Hybrid comfort: combines central-style ducted air distribution with a dedicated ductless wall unit.
- DIY-friendly installation: compatible with MRCOOL DIY Quick Connect line sets to simplify installation and reduce labor complexity.
- Two-zone control: condition the ducted area and wall-mounted zone independently for better comfort and efficiency.
- Cleaner finished look: the ducted air handler can serve larger areas through ductwork while the wall unit handles the separate zone directly.
- Heat pump performance: provides both cooling and heating from one inverter-driven system.
- Smart control ready: compatible with MRCOOL smart controls for convenient app-based operation.

Coverage estimates assume ideal conditions. Indoor-unit ratings describe the individual components; when both zones operate simultaneously, total system output is limited by the outdoor condenser. Final equipment sizing should be based on the building load and the installation manuals.
