Hose/Line HVAC: Service and Repair
A/C Liquid Hose/Line Replacement
Any kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire air conditioning system. Kinks and sharp bends reduce the
flow of refrigerant in the system. High pressures are produced in the refrigerant system when the air conditioning compressor is operating. Extreme care
must be exercised to make sure that each of the refrigerant system connections is pressure-tight and leak free.
WARNING: REVIEW THE WARNINGS AND CAUTIONS BEFORE PERFORMING THE FOLLOWING OPERATION.
