What is the definition of a mini split for heating and cooling? A mini split system is an efficient and cost-effective solution for providing both heating and cooling to a single room or zone in your home. It is a ductless system that consists of two main components: an outdoor condenser and an indoor evaporator connected by a conduit line. The outdoor condenser houses the compressor and condenser coil and the indoor evaporator houses the evaporator coil and fan. The outdoor condenser pulls in outdoor air and the indoor evaporator pushes cooled or heated air into the space. Mini splits are ideal for areas where ductwork is not practical or cost-effective, such as in a home addition or remodel. The advantages of mini splits include energy efficiency, cost savings, ease of installation, and quiet operation. Mini splits are also great for zoning multiple areas of your home to efficiently control temperature, humidity, and air quality. In short, mini splits are an efficient and cost-effective way
