AC drain line in wall

[Jet]

Would installing a air conditioner condensate drain line inside of wall caused the pipe to sweat on the outside because of the cold water. This would added moisture inside of the exterior wall might lead to mildew in the wall or on the drywall. Has anyone built a AC drip line into the wall and has a cause problems. Thanks

Seems like a real concern. Pipe insulation would help. Or run it outside.

Realistically it depends on humidity and dew point. I suspect in Florida you could indeed have a condensation problem but no so much in Arizona. As per the post above, pipe insulation would be the solution. If for some reason there are space limitations and the thick, rigid foam hot water pipe insulation to big or inflexible, you could try Armaflex insulation or HVAC line set insulation.

Definitely no issues with that in AZ.
