If your air conditioner (AC) unit is leaking water, then it means something is wrong with the unit. Such leaks may also encourage mold growth in your home or even cause water damage. Take these measures to prevent your AC from leaking water:
Ensure the Air Filter Is Clean
A dirty air filter causes many problems, and water leakage is just one of them. When the air filter gets too clogged with dirt, it interferes with the flow of air over the evaporator coil, which means the evaporator won't be able to pick up the heat generated in your house. As a result, the evaporator will remain cold, allowing the condensation to ice up. It is this ice that leaks water when it melts.
Preventing this type of air leak is as easy as keeping the filter clean. This means you should wash or replace the filters regularly depending on whether they are washable; doing this every couple of months or so is adequate depending on the level of dirt in your home.
Keep the Condensate Drainage Line Clean
The drain line and hole are meant for channeling away the condensation that inevitably forms in the unit. Normal condensation shouldn't cause any problem if the drainage channel is efficient. However, the condensate drain line can be clogged with dirt, which means the water won't follow its usual channel but will leak into the floor. Prevent such an occurrence by regularly cleaning the drainage channel to get rid of debris, such as mildew, which may clog it.
Maintain Good Seals
As previously hinted, every AC has to form some condensation; that is why it is fitted with the condensate drain line and pan. Because the water isn't mean to contaminate any other part of the unit other than the drainage line, there are watertight seals at possible points of leakage. These points will leak water when they aren't properly fitted or when they have deteriorated and are no longer watertight. The damaged seals also allow warm (moisture laden) air to enter the unit and offload its water; leading to leaks.
Ensure the Drain Pain Is Intact
Sometimes, you may be thinking your unit has a serious water leak issue while, in the real sense, it is the water pan that has holes in it. Maybe the water pan is rusted, especially if it has been in use for a long time, and can no longer hold water properly.
As you can see, there are several issues that may cause your AC to develop water leak problems. Therefore, if you can't diagnose the issue, call a technician for a professional diagnosis and fix. Contact a plumbing repairs service for more information and assistance.
