The most commonly used air conditioning systems include central air conditioning systems and ductless mini-split systems due to their effectiveness in cooling, energy efficiency, and versatility.

Central air conditioning systems are favored for larger homes or buildings, distributing cool air through a system of ducts, allowing for temperature control across multiple rooms with a single unit. This system provides uniform cooling and is ideal for households looking for a whole-home solution.

Ductless mini-split systems, on the other hand, are increasingly popular for their ability to provide targeted cooling. These systems consist of an outdoor compressor and one or more indoor air handling units, which can be installed in individual rooms. This allows different rooms to be cooled to different temperatures, offering flexibility and efficiency, particularly in spaces where installing ductwork is impractical.

These two systems cater to a wide range of residential and commercial needs, making them the most prevalent choices in air conditioning solutions today. Other options, like window units and portable air conditioners, may serve specific situations but do not offer the same level of efficiency and cooling power as central and ductless systems. Similarly, evaporative coolers and geothermal systems are often limited to specific climates and applications, and while split systems and packaged systems are common, they further categorize underneath the
