Install without vacuuming using pre-charged linesets that connect your MRCOOL DIY system in minutes with zero hassle.
The MRCOOL DIY Line Set is designed to install all MRCOOL DIY ductless mini splits. These line sets are compatible with the MRCOOL DIY 5th Gen Single Zone, MRCOOL DIY Multizone, and Central Ducted Mini Split Systems. The included 3/4 in. UV Protective Insulation Sleeve provides extra protection against sun damage, weather erosion, destruction from animals, etc.
Is it compatible with my system?
Yes, if you're using any MRCOOL DIY Series: DIY 5th Gen Single Zone, DIY Multizone, and Central Ducted Mini Split Systems. Select the correct size based on your air handler BTU (9K, 12K, 18K, 24K, or 36K). For Multi-Zone setups, you’ll need one line set per indoor unit to ensure proper performance.
Flexible options for every install
Choose from lengths of 16ft, 25ft, 35ft, and 50ft. Line sets 35ft and up include an extended DIY Pro Cable for fast connection. For extended runs, you can use a coupler to combine two line sets, up to 75ft per zone.
Note: The 16ft and 25ft line sets do NOT include communication wire. The wire is already included in that box if you're purchasing an MRCOOL DIY Air Handler.
