What is a major advantage of mini-split air-conditioning systems?

A major advantage of mini-split air-conditioning systems is that air ducting is not necessary. This feature is significant because it allows for greater flexibility in installation, making them an excellent choice for buildings or areas where traditional ductwork would be difficult or impractical to install. Mini-split systems consist of an outdoor unit and one or more indoor units connected by refrigerant lines, which eliminates the need for extensive duct systems. This not only simplifies the installation process but also allows for zoning capabilities, where different areas can be cooled independently, enhancing comfort and efficiency. Additionally, the absence of ducts can improve air quality since there are fewer places for dust and allergens to accumulate. Overall, the capability to deliver cooling without ductwork makes mini-split systems a preferred choice for various applications, especially in retrofit situations.
