During the summer, the air conditioning system in your Indianapolis home does more than cool the air; it also reduces humidity, making your home feel cooler at the same temperature. The moisture that is pulled from the air condenses on the evaporator coil and drips down into the condensate drain pan. The condensate drain tube then carries this water safely away to the outside of your home.

Condensate Drain Tube Clogs and Their Causes

In order for your HVAC system to run properly, the condensate drain must remain clear and free flowing. Over time, debris like dust, dirt, algae, bacteria, and mold can accumulate in the condensate drain tube, allowing the condensate drain pan to fill with water. This will trip a float switch on most HVAC systems, shutting the system down. If water continues to collect in the pan, it may overflow and spill into the surrounding area, causing stains, water damage, mold growth, and more.

Clearing a Clogged Condensate Drain Tube

If your condensate drain tube is clogged, there are a couple of things you can try before calling an HVAC professional:

  • Shut off power to the HVAC system at the breakers.
  • Locate the condensate drain tube on the outside of your home.
  • Place suction on the drain tube using a shop vacuum.
  • If the clog does not clear, run a flexible wire through the tube.
  • Clear any remaining debris with hot water and vinegar or dish detergent.
  • Restart the system and make sure the condensate continues to drain properly.
