Ductless vs central AC: which fits your home?
Central AC usually wins when ductwork is sound and you want whole-home cooling from one thermostat. Ductless wins for additions, problem rooms, or homes without usable ducts. Many Southern Illinois homes use a hybrid: central for the main floor, ductless for a bonus space.

When to use this
Use this when
You are cooling an addition, replacing aging AC, or comparing quotes that propose mini-splits versus a new condenser and coil.
Compare your options
Choose central when
Ducts are sealed and sized, you want hidden delivery, and whole-home setpoints are enough. Pair with duct improvements if static pressure is high.
Choose ductless when
You need room-by-room control, have no ducts, or want to condition a garage conversion, sunroom, or upstairs that never cools.
Failure modes to avoid
Mini-split sprawl
Solving every room with another head can get expensive and visually busy. Past a point, duct repair plus central cooling is cleaner.
Trust signals
- Compares delivery methods, not brand myths.

FAQs
Can ductless heat too?
Many ductless systems provide both heating and cooling. Ask specifically about cold-weather performance for your rooms if heating is part of the goal.
