Water leakage in an Air-Conditioner

A fully functional air conditioner is the most desirable gadget that every household needs during summer. Sometimes even the small cooling issues can lead to big problems forcing you to compromise on cost and comfort levels during hot, sultry days.

One of the most annoying problems that you may encounter with an air conditioner is the dreaded water leak. A water seepage from the air conditioning system can be challenging indeed and difficult to diagnose. It can have multiple root causes and several solutions. This article focuses on few basic things to be considered if there is a water leak noticed in the air conditioning unit.

Main reasons for water leakage in an air-conditioner:

• Faulty pump: The most recurring cause for water leak in an air conditioner is a faulty condenser pump. The main job of this pump is to drive water out of your house. This is the water that is removed from room air by your air conditioning unit. Due to constant presence of water in the pump, it may get clogged and its capacity to pump water may get hindered. This can be tested by pouring water in the condenser pan to see if it can properly pump out excess water.
• Clogged drain line: There is a drain hole in an air conditioner for the wasted water to be driven out. Over time, dirt gets accumulated that may mix with water thereby clogging the drain pipe. Since water flow in the drain pipe becomes restricted due to congestion, water starts leaking through the main unit. By identifying the exit pipe for your drain, the water leak problem can be solved.
• Improper installation: When the main air conditioning unit and drains are not properly installed, it can cause several problems, including water leakage. A window air conditioner must be installed so that it is slightly lower at the rear than the front. This allows easy removal of water from the room towards back of the machine. If installed too low at the front, this water flows into the room rather than moving outside.
• A frozen coil: If airflow is impeded due to extensive use of the air conditioner, frost can form on the evaporator coil which eventually melts thus causing water seepage. The first thing to check in such a scenario is the air conditioner filter. If filters are clogged, air flow to the system is blocked and ice may form on the coil. Even the intake registers need to be checked to ensure that nothing is blocking the air flow into the system. Turning off the unit for a few hours every few days to allow the ice to melt may prove to be a feasible solution.
• A worn-out insulation coil: The insulation coil, at the back of the main unit is responsible for soaking up condensation that is formed on the copper wire. Due to daily wear and tear, this coil may not function properly, thereby causing water to leak from the back of the unit.

Final word of advice, do contact a reliable HVAC technician to ensure professional handling of the water leakage issue.
