Condensation on pipes


Hello! Our AC is not running properly and I am hoping to get some help figuring out why. The unit is running, blowing air through the vents but it is not cooling the air. In addition, there is a good deal of condensation on the pipe running from the outside unit to the furnace. Any suggestions on how to fix this? Thanks!

You may have developed a refrigerant leak, and need to add gas. Which line is sweating, the larger or the smaller?

Your AC has two moving parts. One for moving air your (blower) the other is the compressor. Your blower is fine because you have airflow, call a tech and have them check out your refrigeration lines. Tell the tech your story and find out what brand your unit is before your call, it may speed it your replacement parts lead time.

Funny, I've got the same similar problem.

My bigger overflow condensation line that runs outside is the one that is heavily condensating. It just started doing this and I've also noticed that the air handler is getting very cold to the touch on the outside of the unit. I've noticed condensation on the outside also. This has just started also.

If your drian line is sweating that is normal when the cold water hits hot air if it is humid outside.

But I've never seen it condensate like it has lately. Another thing is I can hear the refrigerant flowing thru the copper pipe, almost like its starving? I don't know how else to describe it but shouldn't it be almost quiet?
