The 2025 MRCOOL® DIY Hybrid™ Ducted Air Handler brings full central HVAC comfort to DIY installers.

Use the DIY Hybrid™ Ducted Air Handler as a central zone in your home’s duct system, then add MRCOOL® wall or ceiling air handlers to the same outdoor condenser for a multi-zone setup.
Sizing Example:
Add the BTUs of the ducted air handler and all additional indoor units to select your outdoor condenser size — just like sizing a multi-zone mini split.
| Model | Capacity | Typical Coverage | Use Case |
|---|---|---|---|
| DIY Hybrid™ Ducted 24k | 24,000 BTU | Up to ~1,000 sq. ft. | Central zone or medium home area |
