Mini split vs. central AC: which is right for your home?

Central AC cools your whole house to one temperature and pushes that air through ducts. A ductless mini split conditions each room independently with no ducts at all. Everything else — cost, efficiency, comfort — flows from that one design choice.

Neither is universally 'better' — they're built for different homes. The table below is the honest version we walk customers through.

• Your home already has healthy, well-sealed ductwork.
• You're fine with one temperature for the whole house.
• You're replacing an existing central system that's served you well.

If that's you, replacing a central system is often the simpler path — and we'll say so.

• There's no ductwork, or the ducts are old and leaky (duct loss runs 25–30%).
• You have hot/cold rooms central air can't balance.
• You want lower bills and the ability to condition only the rooms you use.
• You're adding a space — addition, garage, casita — where extending ducts is impractical.

Good ducts + whole-house simplicity → central. No ducts, problem rooms, or efficiency goals → ductless. Many San Antonio homes are a hybrid: keep the central system and add a zone or two where it falls short. We'll tell you honestly which camp you're in.
