How long are the line sets that come with the unit?

Thank you for your question. This system package includes the MRCOOL 27K BTU Multi-Zone Condenser, 9K BTU Wall Mounted Air Handlers, 12K BTU Wall Mounted Air Handlers and 2 Remotes. However it does not include the line sets. Under the accessories, 25' and 16' line set lengths can be purchased separately. For assistance, please give us a call at 1-888-295-2009.
