Simply attach a dry/wet vacuum cleaner to the pipe and allow it to remove the blockage. If that doesn’t solve the issue, replace the air conditioner’s filters. Occasionally, the filters get so dirty that they block airflow to the evaporator coil, which in turn causes water leakage.

Why does my air conditioner leak?
There are only a few causes of a leaking air conditioner, the first one being a clogged air filter. When your air filter is dirty, air cannot pass through as easily , which causes the evaporator coils to freeze up. Since refrigerant flows through your evaporator coils and requires proper airflow to absorb heat, if airflow is restricted, ice will form and drip water. Frozen evaporator coils can also be caused by dirty coils, blocked vents/registers, broken blower motor, or lack of refrigerant.
How do I clean a condensate line?
The condensate line can become blocked with fungi, algae, and debris. It’s necessary to clear the drain line every once in a while. You can call a professional or try to do it yourself: 1 Locate the PVC pipe near your air handler’s drain pan. It should have a piece of pipe sticking up at a 90 degree angle with a little cap on top. 2 Unscrew the cap and pour about six ounces of vinegar down the drain line . Doing this every few months will kill any algae or fungi that develops in your line. If your drain line is still clogged, you will have to decide if you will call a professional or use a wet-dry vac to clear the line yourself. 3 Locate your outdoor condensate drain line near your condenser unit, connect your wet-dry attachment, and turn the vacuum on. Most home improvement stores sell an attachment that connects your wet-dry vac with your outdoor drain. Learn more by watching the video below:
