A split style air conditioner is a type of air conditioning system that is composed of two separate units: an outdoor unit and an indoor unit. The outdoor unit houses the compressor, condenser, and expansion valve, while the indoor unit contains the evaporator and fan. This type of air conditioner is popular due to its flexibility and ability to cool multiple rooms or areas. It is also energy efficient and can be used to both heat and cool a space. Split style air conditioners are typically installed by a professional, and require regular maintenance to ensure they are running at their best. They are also more expensive than other types of air conditioners, but offer a more efficient cooling system. Split style air conditioners are a great choice for those looking for a reliable and efficient cooling system for their home or business.
