A ductless HVAC system, also known as a mini-split, consists of one or more indoor air handling units connected to an outdoor condenser.

Advantages of Ductless HVAC System:

1. Zoning Control: Ductless systems offer individualized temperature control for each room, enhancing energy efficiency and comfort.

2. Easier Installation: Since there's no need for ductwork, installation is usually less invasive and more straightforward, making them suitable for retrofitting existing homes.

3. Energy Efficiency: Ductless systems can be more energy-efficient due to the absence of duct-related losses.

Ultimately, the decision between a ducted and ductless HVAC system depends on factors such as your budget, home layout, cooling/heating requirements, and personal preferences.
