Function

• A mini split is a ductless heat pump system that is comprised of two portions, including an air unit for indoors and a condenser positioned outside. They are connected with conduit for communication.
  
  

Troubleshooting

• It is possible for ice to build up on the inside portion of the mini split. Verify that the blower wheel can move, as well as the motion of the fan. Other items to check for functionality are the control board, motor and the level of refrigerant.
  
  

Considerations

• Troubleshooting the system before calling a repair person is a smart way to save money, especially if it is a simple fix. Mini split systems have very few trained service personnel that work with them, so labor may be costly if a repair is needed.
