The answer to 'difference between central air and mini split' is that central air conditioning systems are a single, whole-home solution, while mini-split systems are ductless and can cool individual rooms or zones. Central air uses a single outdoor compressor and indoor air handler to cool the entire house, while mini-splits have multiple indoor air handlers connected to a single outdoor unit.
Central air systems are better suited for larger homes, while mini-splits are more flexible and efficient for smaller or multi-zone spaces. Mini-splits also don't require extensive ductwork, making them easier to install in existing homes. However, central air may have a lower upfront cost and can provide more consistent cooling throughout the home.
