Why is my suction line dripping?

Answer by  Christian9247 (5042)

This is probably but not limited to improper insulation. It can be caused by the saturation suction level of the temperature causing a change in temperature and thus condensation. Usually this is normal for the condensation to drip but excessive dripping may be a problem.

The main reason for dripping can be improper insulation. You can buy insulation tape from a hardware store and insulate the pipe. Sealing all the cracks with a tape also helps to prevent the dripping.

The saturated suction temperature of R22 during normal operation is about 50 -55 degrees F. This temperature is normally below dew-point, which is the point where water will condense out of the air. So moisture in the air is condensing on the cooler line. A properly installed unit has the suction line completely insulated.

The suction line is supposed to drip when humidity builds up in the a/c unit. It is perfectly alright. You should worry when you run a/c and it doesn't drip.
