Why Is My AC Leaking Water?

Leaking Air Conditioner

When problems arise with your air conditioner, you need solutions and repairs as quick as possible. Fortunately, for home and business owners in South Florida, Freezing Mechanical is here to solve any and all of your HVAC needs, including water leaking from your AC or pooling from or near the unit.

As air conditioning works to cool the home, water builds up along the evaporator coils. When everything is running as it should, that water is carried away from your house along the condensate drain line, ultimately making its way into a drain pan. However, if you notice a leak in your unit, something has gone wrong during that process. Here are a few common causes of a leaking AC and cures on how to restore peak efficiency to your system.

Dirty Air Filter/Frozen Evaporator Coil

When your air filters are dirty, the airflow along the evaporator coils is diminished or stopped entirely, causing the coils to freeze. Eventually, that ice melts, dripping excess water and sometimes overflowing the pan. Oftentimes, the combination of a dirty air filter and frozen evaporator coil can be the source of a leak. Air filters should be cleaned or replaced regularly, usually every 30 days for Florida HVAC owners.

Evaporators can also freeze when the AC unit does not have enough refrigerant. If the house is not cooling down properly or the AC unit begins to make a hissing sound, those could both be warning signs that the refrigerant is leaking and the unit will need to be repaired or even replaced entirely.

Clogged Condensate Drain Line

Your AC’s condensate drain line is responsible for carrying the water away from your house and into the drain pan outside. However, the drain line can often become obstructed by blockage such as mud, dust, mold and other debris. If you have diagnosed a clogged condensate line, don’t delay. Vacuum the drain line to avoid water backing up into your home and causing potential water damage. For foolproof results and speedy resolution, you should hire an HVAC professional equipped with a specialized vacuum to clear any obstructions and ensure the situation doesn’t turn into a bigger issue and much costlier repair expense.

Broken Condensate Pump

If gravity doesn’t help the drain line in running water towards the drain pan outside the house, then your system relies on a condensate pump to provide the extra boost. If the pump fails, water will be unable to flow away from your home, resulting in pooling up, leakage and potential damage. Call a trusted and experienced technician to find the correct replacement and resolve the malfunctioning pump.

Rusted or Improperly Installed Drain Pan

Rusts in the drain pan can make the part unable to collect the water delivered through the drain line, resulting in leakage or spillage. An improperly installed drain line or drain pan can also cause water to leak into unwanted places. That’s why it’s crucial to have an HVAC company you can trust to perform any installation or repair job.
