A ductless air conditioner is a type of cooling system that does not require ductwork to distribute air. Instead, it consists of an outdoor unit and one or more indoor units that are mounted on walls or ceilings. This design allows for efficient cooling of individual rooms or zones, making it ideal for homes without existing ducts. These systems are known for their energy efficiency and flexibility. They can be controlled independently, allowing users to set different temperatures in different areas. Additionally, ductless air conditioners often include features like air filtration and heating capabilities, providing year-round comfort.
