Ductless mini-split systems are designed for easier installation and require less maintenance compared to other types of air conditioning systems. These systems consist of an indoor and an outdoor unit, connected by refrigerant lines, which minimizes the need for extensive ductwork that is typically required for central air conditioning systems.

The installation process for ductless mini-splits is relatively straightforward, often requiring only a small hole for the refrigerant lines to pass through, making them suitable for retrofitting into homes without existing ductwork. This simplicity contributes to reduced overall installation time and labor costs.

In terms of maintenance, ductless mini-split systems generally have fewer components than central air or chilled water systems, which often require regular maintenance of ductwork and complex refrigeration controls. Ductless systems typically need periodic cleaning of the filters and occasional checks of the refrigerant levels, making upkeep manageable for homeowners.

Overall, the combination of straightforward installation and minimal maintenance requirements makes ductless mini-split systems an attractive option for those looking for efficient cooling solutions.
