VRF or Split for Large Residential Home

[Designer_82]

Working on high end home roughly 9,000 sq.ft. 2 floors with basement and attic for HVAC equipment.

Thinking either split units (First Co. indoor units w/ hydronic heating) with elec. cooling outdoor condensers. Or VRF system.

What would be some deciding factors whether to go VRF or Split on this house? Is it if the owner wants more control of individual spaces and overall better efficiency?

Or other factors?

Climate and use would be deciding factors.

VRF is a split system. Unlike a window unit, you split condenser and evaporator in separate devices. Maybe define what system you mean by "split" if it isn't VRF. Most smaller systems are split systems. Non-split would be a water-cooled chiller etc.
