How To Repair Stopped Up Air Conditioner Drain Pipe

An important part of your air conditioning unit is the drain pipe, also known as a drain line, drip line or condensation line.

The purpose of the drain pipe is to remove excess condensation that naturally occurs inside the air conditioning unit.

When the drain pipe becomes clogged with mold, mildew or other debris, excess moisture will leak from the air conditioner and into your home, creating water damage and possibly an expensive repair bill.
