Why is Your A/C Leaking Water?


Have you noticed that your air conditioner or heater is leaking water? There are several possible reasons for this, but whatever the cause, you’ll want to call in a professional A/C technician to troubleshoot your system.

In the meantime, here are some common reasons why your residential A/C may be leaking:




1. The condensate drain is clogged.


This drain helps transport collected water out of the unit. If rust, dirt, debris or algae builds up, it can partially or completely block and clog the drain and cause the A/C to leak.





2. The temperature is too cold to run your A/C.


If you try to get the unit to cool your home when it’s cold outside, the evaporator coils can ice over, causing the unit to leak. To avoid this problem, don’t run your A/C when the temperature is below 60 degrees.




3. The drain line is disconnected


Even if your A/C is installed correctly, it’s not unheard of for the drain line to become loose over time. If it gets loose enough, it can completely disconnect from your AC, which will cause leakage.



4. The condensate pump is broken


If your condensate pump is broken, it can’t pump out the excess water in the condenser pan, so the pan will fill up and start overflowing (or leaking).





5. The refrigerant level is too low.


Low refrigerant can make the A/C coils freeze, which can then cause leakage as the drip pan overflows.





6. The air filter is dirty.


When the air filter becomes dirty, airflow is restricted and the evaporator coils don’t get the ventilation they need. This causes the coils to get too cold and eventually freeze. As the ice melts off the coils, moisture will drip down, causing the drip pan to overflow and eventually leak.

It’s normal for a well-functioning A/C to produce a little bit of condensation at times. The more your A/C is on and running, the more condensation you’ll have.

However, when excess water is regularly leaking from the unit, you don’t want to ignore it. If you notice that it’s leaking for more than a day, contact an experienced A/C technician right away.
