Condensation on AC vent?

Question

For the first time last nite, i noticed a little bit of condensation on the AC vent in my kitchen. Today, the condensation is gone, but it seems like the AC isn't running as well. Is the random condensation evidence of a problem, or is that normal?

Answer 1

The air delivered from the vents is well below the dew point temperature of the surrounding air.Kind of like a cold soda can on the kitchen counter.It will also sweat.

When the relative humidity is high,the registers will sweat from time to time.It will not be all the time though,and I don't feel you have to be worried about your unit.

Good luck.
