How to Troubleshoot a Leaking AC and Save Money


A working air conditioner is essential to staying cool and comfortable in central Florida. When problems arise, you need solutions and repairs as quickly as possible. One of the most common issues you may run into with your AC involves water leaking or pooling from or near the unit. As the AC cools the home, water builds up along the evaporator coils. When everything is working smoothly, that water is carried away from the home along the condensate drain line and into a drain pan. But if you notice your AC has started to leak, something has gone wrong during that process. Here are a few possible reasons your home’s AC unit could be leaking.

Clogged Condensate Drain Line

Clogs can be caused by mud, dust, mold or other debris. If your AC’s drain line is obstructed by blockage, you will need to vacuum the drain line to avoid water backing up into your home and causing potential water damage. For surefire results, you should hire an HVAC professional equipped with a specialized vacuum.

Broken Condensate Pump

If the drain line does not have the benefit of gravity to run the water towards the drain pan or outside the house, then it relies on a condensate pump to provide the extra boost. If the pump fails, it will need to be replaced because the water will be unable to flow away from your home and will instead pool up and leak.

Dirty Air Filter/Frozen Evaporator Coil

A dirty air filter stops the airflow along the evaporator coils, causing them to freeze. As the ice melts, it drips excess water and sometimes the pan overflows, which can be the source of a leak. Air filters should be cleaned or replaced regularly, at least every 30 to 90 days.
Evaporators can also freeze when the AC unit does not have enough refrigerant due to the drop in pressure in the system. If the house is not cooling down properly or the AC unit starts hissing, those are indicators that the refrigerant is leaking and the unit will need to be repaired or replaced.

Rusted or Improperly Installed Drain Pan

A rusted drain pain is unable to collect the water delivered through the drain line, so the water simply spills out again. An improperly installed drain line or drain pan can also cause water to leak into unwanted places.
