Many Santa Barbara homes were built without air conditioning, and plenty were built without ducts at all: wall furnaces, floor furnaces, or nothing. When those owners want cooling, the first question is usually whether to go ductless or put in a central system. Both can be the right answer.
What each one is
A central system uses one indoor unit, usually a furnace or air handler with a coil, connected to ductwork that carries air to every room, and one outdoor unit. A ductless mini-split uses small indoor units mounted in the rooms (on a wall, in the ceiling, or on the floor), each connected by refrigerant lines to an outdoor unit. Most mini-splits sold today are heat pumps, so they heat as well as cool.
When ductless usually makes sense
- There are no ducts, or the old ones are in poor shape. Adding ductwork to a finished older home can mean opening walls and ceilings or giving up closet space.
- You want to treat some rooms, not all. A bedroom that bakes in the afternoon, a converted garage, an ADU or an addition.
- Different rooms need different temperatures. Each indoor unit has its own control.
- There's little room for equipment. No attic or crawl space for an air handler and ducts.
When central usually makes sense
- The house already has ducts in good condition, often from an existing furnace. Adding a coil and an outdoor unit, or replacing both with a heat pump system, uses what's there.
- You want even heating and cooling across the whole house from one system and one thermostat.
- You'd rather not see equipment on the walls. Central systems hide everything but the vents.
There's a middle ground
Ducted mini-splits use a compact air handler with short duct runs, hidden in a closet, attic or soffit, to serve a few rooms through regular vents. They suit additions, ADUs and second floors where a full central system is more than you need.
Questions that decide it
- Are there ducts now, and what condition are they in?
- Is there an attic or crawl space with room to work?
- Which rooms matter most, and do people want different temperatures?
- Are you replacing a gas furnace too? A heat pump, central or ductless, can do both jobs.
