Is the unit pre-charged with refrigerant?

Thank you for your question. This product is an indoor installation kit for a mini split system. The refrigerant line set included in this installation kit is not pre-charged. However, depending on which mini split system that you use it with, most mini split outdoor condensers come factory charged with a minimum amount of refrigerant (this varies by condenser). Your licensed technician will be able to adjust refrigerant levels for you. For more assistance, please give us a call.
