Your air conditioner provides relief when hot, humid weather grips the Delaware Valley. Problems like a broken blower motor or depleted refrigerant require professional service. A water leak, however, could be something that you can remedy yourself. The steps for how to fix a leaking air conditioner depend on the source of the leak. Dripping could come from ice formation on frozen evaporator coils or a cracked drain pan. A blocked condensate drain is another common culprit.
A wet-dry vacuum clears away pooled water and could be needed to unclog a condensate drain.

- Outdoor drain attachment for wet-dry vacuum
How to Fix a Leaking Air Conditioner
- Turn off power to the AC unit at your breaker box.
- Because frozen evaporator coils frequently cause dripping, begin by inspecting your air filter.
- You may need a screwdriver to access the filter and a flashlight to inspect it.
- The airflow restriction caused by a dirty, clogged filter could freeze the evaporator coil.
- Replace the filter to restore proper airflow.
- Change the filter every 30 days thereafter during the season.
- Check your vents to ensure that they are open or unblocked so that air can flow correctly.
- Instead of a frozen evaporator coil, your leak might stem from a cracked drain pan.
- Make sure power is turned off.
- Inspect the drain pan beneath the air handler for leaks or cracks in the pan or connection pipe.
- Use water sealant products, such as a spray, paint, or tape, to fix the leak.
- If you do not see any evidence of cracks in the drain pan, look at the condensate drain.
- With the power still off, find the PVC pipe by the drain pan that has a small cap.
- Remove the cap and pour vinegar through the drain line.
- If vinegar rinsing does not produce results, try clearing the line with the wet-dry vacuum.
- Set up the wet-dry vacuum outside by the condensate drain line and fit it with the outdoor drain attachment.
- Draw blockages out of the drain line with the vacuum.
- Restore power to the air conditioner and see if it returns to normal function without leaks.
