I have a 6 year old unit but the suction and high lines are about 20 years old and so is the insulation on them. The air conditioner is working very well except for condensation dripping from the suction line. Is it just a failure of the insulation or.......? The coils are clean. I was told the lines are leaking and had to be replaced but if this was true I don't think the unit would working as well as it is. Any thoughts.
Thanks
