The definition of a mini split heating and air system is a type of heating and cooling system that uses an outdoor compressor and indoor air handlers to provide climate control for a single room or multiple rooms. Unlike traditional HVAC systems, mini split systems are ductless, meaning they don’t require the installation of ductwork. Instead, they use small, flexible refrigerant lines to connect the outdoor compressor to the indoor air handlers. The air handlers are mounted on the walls or ceilings of the room or rooms, and are connected to the compressor via the refrigerant lines. Mini split systems are energy efficient, cost effective, and provide greater control over individual room temperatures. They are also ideal for homes or businesses that don’t have the space for traditional ductwork. With a mini split system, you can customize the temperature in each room, allowing you to keep certain rooms cooler or warmer than others. This is especially useful in multi-level homes or businesses where different levels may need different temperatures.
