💡 Pro Tip: Managing Line Length

If your 25ft lineset is longer than your route, do not shorten or cut the lines. Simply coil the excess into a large horizontal loop and store it flat behind the outdoor unit. This ensures optimal R-454B refrigerant flow and prevents oil traps that can damage the compressor.
