A split system air conditioner is a type of cooling system that uses an outdoor condenser unit and an indoor air handler to cool the air in a space. The condenser unit is located outside the home and is responsible for transferring heat from the air inside the home to the outside air. The air handler is located inside the home and is responsible for circulating the cooled air throughout the space. The two units are connected by refrigerant lines that transfer the cooled air from the condenser unit to the air handler. Split system air conditioners are a popular choice for cooling residential and commercial spaces due to their efficiency and ability to provide cooling in specific areas. They are also more cost-effective than other types of air conditioners, as they require less energy to operate. Additionally, split system air conditioners are quieter than other types of air conditioners, making them a great choice for those who want to maintain a peaceful environment.
