Installation Tips for Optimal HVAC Performance
Verify Maximum Line Length with Manufacturer Guidelines
Check your HVAC or mini split equipment manufacturer’s recommended maximum line length to ensure efficient performance and warranty compliance.
Plan Line Routing Carefully
Avoid tight bends and sharp turns that can impede refrigerant flow or damage insulation. Plan routes to allow smooth line transitions.
Secure Tubing with Appropriate Supports
Use line clamps or straps to secure the copper pipe through wall penetrations and along mounting surfaces to reduce vibration and wear.
