A ductless mini split indoor unit is a type of air conditioning system that is becoming increasingly popular due to its flexibility and efficiency. It is an all-in-one system that combines the functions of a furnace, air conditioner, and air handler into one unit. The indoor unit is connected to an outdoor unit via refrigerant lines, and the two units work together to cool or heat a space. The indoor unit is typically mounted on a wall or ceiling and contains a fan, evaporator coil, and compressor. The fan circulates air through the evaporator coil, which cools the air and sends it into the space. The compressor then pumps the refrigerant back to the outdoor unit, where it is cooled and sent back to the indoor unit. This process continues until the desired temperature is reached. Ductless mini split indoor units are energy efficient, easy to install, and provide zoned temperature control. They are also a great option for homes or businesses that don’t have existing ductwork.
