dripping AC

An air-conditioning system leaking water can cause costly damage to your floors, furnishings, walls, and ceilings. What’s more, it could result in compressor failure. Take these steps if you have a dripping AC unit.

Change Your Air Filter

A clogged air filter restricts airflow, which could lead to the evaporator coils freezing up and dripping water. Blocked vents or registers can also cause frozen evaporator coils. Replacing your filter and ensuring no vent or register is covered will help solve the issue.

If cleaning or changing your filter doesn’t fix the dripping AC, your unit could be low on refrigerant. You’ll need a technician to identify the origin of the refrigerant leak.

Replace the Drain Pan

The drain pan located below your indoor air handler can rust or become damaged over time, causing condensation to leak rather than flow into your drain line. You can clean the pan and then inspect it for cracks with the help of a flashlight. Water sealant can fix a cracked pan temporarily. However, replacing a damaged pan with a new one that’s appropriately sized for your system is the best solution.

Clear the Condensate Drain Line

Algae, fungi, and other debris can block your system’s condensate drain line and cause your air conditioner to leak water. You can contact a professional to clean the drain line for you. To clear the line yourself:

  • Shut your AC unit down and check the drain pan for standing water.
  • Empty the pan and clean it thoroughly.
  • Scrub the condensate drain line thoroughly with a wire brush. You may have to use a wet/dry vacuum or a special pump if the line is clogged severely.
  • To ensure the line is unblocked and clean, pour some water and check if it flows seamlessly to the other end.

You should address AC leaks and dripping ACs as soon as possible. Annual HVAC tuneups that include drain clearings and full cleanings will help prevent dripping AC problems in the summer.
