What size should I get?

  • The correct line set size depends on your mini split system. Always refer to the manufacturer’s specifications to ensure compatibility.
  • Measure the distance between your indoor and outdoor units
  • When in doubt, choose a longer line set. Most systems require a minimum length of 15 feet to function correctly, while exceeding the manufacturer’s maximum limit can cause performance issues.
