This 16 ft. copper line set connects the MRCOOL Condenser to the MR COOL Air Handlers. 100% accurately pre-charged with R-410A refrigerant. For Multi-Zone systems, one line set per indoor unit is required to ensure the system will function properly.

This lineset does NOT come with communication wire. However, if you are purchasing a MRCOOL DIY system with an Air Handler, a 25' communication wire is included in the Air Handler box.
