HI, I live in Atlanta, GA in a one story home with a crawl space and attic.
I have a split system A/C unit, electric with gas furnace, that is approximately three years old.
The furnace/air-handler is in the attic. And of course the compressor and condensing unit is outside.
I had it serviced last year. It only needed to be charged a little.
Temperatures here lately have been in the 80's during the day, 70's at night.
The two lines running from the compressor to the air handling unit run through my crawl space and up
through an interior wall in the house, up to the attic.
My problem is that I was in the crawl space and I noticed water. One of the A/C lines is wrapped in
an insulator and the other is not. The one that is wrapped is completely soaked with water. When I squeezed
the insulator, water ran from it. It appears to be a lot of condensation.
There is no water in the overflow pan under the air handling unit.
The evaporator drain does not appear to be clogged.
What is causing all of this water?
What do I do to correct the situation?
Thank you

extremely high humidity in the crawl space or very low refrigerant temp. be sure all filters are clean, vents unobstructed, etc. is there plastic down in the crawl?

Hi,
Thank you for the reply.
There is plastic in the crawl. I checked that yesterday.
I do have alot of humidity in the crawl however.
My building does not have gutters, and there is mold/fungus around all edges of the building in the crawl. There are adequate ventilation grates all around. We will be getting gutters soon.
Is the humidity causing the condensation?
Is a very low refrigerant temp a problem, or a good thing?

would not be good, generally caused by inadequate evaporation at the indoor coil. humidity does appear to be the problem. ventilation will help a great deal.
