Do you sell the line sets and control wire needed to install this unit?

Yes, we do have the line sets and control wire, as well as other accessories, available for this system. These items can be additionally purchased as accessories for this system. We would recommend our ductless mini split indoor installation kit for the air handlers. This kit includes the line set, the control wire and the condensate drain line. This kit comes in 15', 30' and 50' options. You will need one kit per air handler, so 4 kits in total for this 4 zone system. We would also recommend the ductless mini split installation kit for condensers. This kit for condenser includes electrical components required for installation. You will only need one of these kits since there is only one condenser. We would also recommend an equipment pad or mounting bracket for the outdoor condenser to keep it up off the ground and to reduce vibration. Line set cover guards are also recommended to both protect and camouflage the line sets. If installation requires the condensate drain line to run against gravity, you will also need a condensate pump. All these accessories can be found in the accessories section which is located on this product's page under the "add to cart" button. For more assistance, please give us a call.
