HVAC Air Conditioner Leaking - Air Handler Condensation Drain - Condensation Leaks

This is an air conditioner condensation drain pipe drains the condensation from the evaporator coil. The evaporator coil operates below the dew point when the system is in air conditioning mode. As humid air passes over the cold evaporator coil the humidity or moisture in the air condenses. The condensation runs down the coil and into a condensation drain pan. Attached to the condensation drain pan is the condensation drain pipe. This air handler condensation pipe usually terminates outside the building at the base of the foundation. On very humid days lots of humidity or condensed moisture is removed from the air when the air conditioner is running. It is important for the condensation drain pipe to remain open or unclogged so this condensed moisture can drain properly. If you find moisture around the base of an air handler it is quite possible that this air handler condensation drain pipe is plugged and needs to be flushed.

Notice this pipe has insulation on the horizontal run. The pipe insulation is black and is called rubatex. The rubatex insulates the condensation pipe keeping it from sweating. If the air handler condensation pipe were to sweat it would leave the area under the air handler condensation drain pipe wet and this leads to water damage and mold. It is very important to make sure all the moisture created by the condensed moisture and air handler condensation drain pipe drain to the outside of the dwelling to prevent water damage and mold growth.
