condensation on suction line


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

When the unit is running, the suction line is below the dew point and therefore will sweat. I'd replace that insulation though, it's easy and cheap, you can get it at Lowes.

Probably just needs reinsulated.

Its fairly common for older insulation to deteriorate, and cause condensation to form from normal operation.

When you where told the line set was leeking did the tech add freon or not?

Insulation is what you need.

if you get the lenghts of armaflex tubing size it on the diameter of the copper so it is tight no air between it and the piping.on the elbows use the caulk insulation tape..it insulates and is tacky and is tight on those elbows

Reinsulate the line, and find yourself a new pro that knows how to diagnose a leaking system.

Yep...Gas and Go...The contact number is only in service until the refrigerant tank runs out...it is amazing that they can get 50# of refrigerant out of a 30# tank...and without even using a scale.

It pays to know...even if you don't DIY. (...and it costs not to know.)
