A multi zone mini split system is a ductless air conditioning and heating system with multiple indoor units connected to a single outdoor unit. Each indoor unit is responsible for controlling the temperature in a different zone of your home, so it’s ideal for those who want to reduce energy costs while still providing comfort in different areas. The outdoor unit contains the compressor and condenser and is responsible for cooling the refrigerant and sending it to the indoor units. Each indoor unit contains an evaporator, fan and expansion valve to send the cooled air into the desired zone. The evaporator is responsible for absorbing heat from the air, the fan distributes the air throughout the indoor space and the expansion valve regulates the flow of refrigerant. With a multi zone mini split system, you have the ability to control the temperature in each zone of your home individually, making it easier to tailor the comfort to your needs.
