A mini-split system, also known as a ductless mini-split, is specifically designed to provide air conditioning without the need for ductwork. This type of system consists of an outdoor compressor unit and one or more indoor air-handling units. The indoor units can be mounted on walls or ceilings and deliver cooled air directly into the living spaces.

One of the main advantages of mini-split systems is their flexibility in installation, allowing for zoning capabilities. Homeowners can cool individual rooms or areas independently, which can lead to enhanced energy efficiency since you can condition only the spaces that are in use. Additionally, since they do not rely on ductwork, mini-split systems eliminate the energy losses often associated with ducts, which can account for up to 30% of the energy consumption for heating and cooling in a typical home.

Moreover, they are quieter than many traditional systems and can provide both heating and cooling, making them a versatile choice for homeowners looking for efficient heating and cooling options without extensive modifications to their existing home.
