Do mini-splits dehumidify?

Yes, while cooling, and many have a dry mode. Sizing still matters.

Can a mini-split cool a whole house?

Multi-zone systems can, but central systems are often simpler in homes with good ducts.

	Central (ducted) system	Ductless mini-split
Distribution	One air handler and ducts to every room	Indoor heads mounted in each room or zone
Best for	Whole-home cooling with usable ductwork	Additions, garages, sunrooms, hard-to-cool rooms, homes without ducts
Zoning	Possible with zoning dampers	Built in: each head has its own control
Duct losses	Depend on duct condition and location	No duct losses
Maintenance	One filter, one drain	Each head has a filter and a drain to keep clean
Appearance	Hidden registers	Visible wall, ceiling or floor units

Do you have ducts in good condition? Central usually makes sense
Adding a room the current system can't serve? A mini-split avoids overloading it
One room always hot? Fix ducts first; a mini-split if that's not practical
Converting a garage or lanai? Mini-split, with code and permit checks

Costs depend on equipment, number of zones, line-set lengths and electrical work. We'll quote your actual project in writing.
