In Delray Beach, FL air conditioners remove some 20 gallons of humidity every day. This excess moisture gathers on the evaporator coils, trickles into a drain pan and flows outside your house through the condensate line. At least, that’s what should happen.

How to Check Your AC Condensate Line

To determine if your condensate drain is working properly, check the exterior drainpipe when your air conditioner is running. You should see a steady trickle of clean water. If that’s not the case, the line could be clogged. The drain might also be connected to your interior plumbing with the exterior pipe only handling overflow.

If you have a split system where the evaporator coil and air handler are located inside your living spaces, attic or garage, it’s especially important to check the drainpipe. Due to the risk of water damage, there are special code requirements for these systems. You can check the drain pan by removing the air handler access panel.

  • Inspect the drain pan for standing water, rust and corrosion.
  • Evaporator coils that are covered with ice could indicate airflow problems, dirty coils or improper refrigerant levels.
  • If your AC system is shutting off frequently, the float valve could be telling the system that the condensate isn’t draining.

What to Do if Your Condensate Drain Is Clogged

You can clear most clogs with a wet/dry vacuum or basic cleaning products. If you feel comfortable, try one of these solutions.

  • Combine equal parts bleach and warm water. Pour this mixture directly into the drainpipe opening. Once the pipe is clear, flush it with several cups of tap water.
  • Alternatively, use a mixture of distilled vinegar and warm water to loosen debris and inhibit algae growth. Flush the pipe with clean water afterward.
