The answer to 'mini split vs' is that mini-split and central HVAC systems each have their own unique features, benefits, and use cases. Mini-splits are ductless, highly efficient, and great for cooling/heating specific rooms or small homes, while central systems provide whole-home climate control through ductwork.
Mini-splits have indoor wall-mounted units connected to an outdoor compressor, allowing for flexible, targeted heating and cooling. They're often easier to install than central systems and can be more energy-efficient. Central systems distribute conditioned air through ductwork to multiple rooms, providing whole-home comfort, but may be more complex to install in existing homes without existing ductwork.
