$5 - $15 (for cleaning supplies)

Diagnosis

An air conditioner that's dripping water is often experiencing a blocked drainage pipe. This pipe is supposed to carry away the condensation that naturally forms as your AC cools the air. When dust, mold, or other gunk stops up this line, the water has nowhere to go, leading to leaks inside your home and potentially creating a damp environment for mold to grow.

Tools Needed

  • Wet/dry vacuum cleaner
  • Pliers
  • Bucket
  • Gloves
  • Mask
  • Stiff wire or pipe cleaner
  • Screwdriver (if needed to access drain line)

Warnings

  • Always turn off the power to your AC unit at the breaker box before starting any work to prevent electrical shock.
  • Wear gloves and a mask to protect yourself from mold and bacteria that may be present in the drain line.
  • Be careful not to damage the PVC pipes or electrical components of the AC unit.

Step-by-Step Instructions

  1. First, make sure to turn off the power to your air conditioner at the circuit breaker.
  2. Find the drain line for condensation. It's typically a PVC pipe located near the outdoor unit or coming out of a wall close to the indoor unit.
  3. Position a bucket beneath the end of the drain line to catch any water that might come out.
  4. Gently detach the drain line from the air conditioner or the main pipe, using pliers if needed.
  5. Use a wet/dry vacuum to pull out any obstructions and water from the end of the pipe for a few minutes.
  6. If the vacuum doesn't solve the problem, carefully push a sturdy wire or pipe cleaner into the line to break up the blockage.
  7. Once clear, reattach the drain line, ensuring it's secure.
  8. Pour about a cup of water into the drain pan, which is usually located near the indoor unit, to check that it now drains smoothly.
  9. Restore power to your air conditioner at the breaker box.
  10. Keep an eye on the unit to confirm that the water leakage has stopped.

Troubleshooting

  • If water still leaks, the clog might be further up in the line or in the drain pan itself. Try flushing the line with a mixture of vinegar and water.
  • Check if the drain pan is cracked or overflowing, which could indicate a separate issue or a complete blockage.
  • If you cannot locate the clog or the leak persists, it may be time to call a professional HVAC technician.

Preventive Tips

  • Schedule annual maintenance for your air conditioner with a qualified technician.
  • Regularly check the condensate drain line outlet for any visible blockages.
  • Pour a cup of vinegar down the drain line every few months to help prevent algae and mold buildup.
