Why is My Air Conditioning Leaking Water? 

If your air conditioner has begun to leak water, you can take steps to prevent further water damage and ensure the system stays operational. You can perform repairs yourself or call a professional if you’re unsure of the best approach. Some common causes are clogged condensate drain lines, low refrigerant levels, and a broken condensate pump.

Clogged condensate drain line 

If you suspect your air conditioner is leaking water, the first step is to clean out the drain line. You can use a long wire brush to get rid of any debris that has built up. If you can’t get the clog out yourself, call a plumber. Professionals will have the right tools to remove any clog from the drain line, including special equipment. 

If the drain line is clogged, you’re in for a big surprise! The first sign of a clogged drain line is water that is pooling in the drain pan. This water can cause damage to your home and to your HVAC system. A dirty filter can cause this problem, but you can prevent it by cleaning it frequently. 

Low refrigerant level 

If your air conditioning system starts to leak water, it’s probably due to a low refrigerant level. Low refrigerant levels can affect the compressor and evaporator coil. As these components freeze, water will drip from the evaporator coil and into the drain pan, which will eventually overwhelm it and cause a leak. 

A faulty installation is another common cause of water leaks from air conditioning systems. A poorly installed air conditioner can have loose drainpipe fittings that allow water to drain into the wrong place. This is especially common with newly installed units. However, by following a routine maintenance schedule, you can increase your AC’s efficiency and minimize costly repairs. Routine maintenance also involves checking the refrigerant levels in your AC unit. 

Rusty drain pan 

Rusty drain pans in your air conditioning system can cause water to leak from the unit. This is caused by corrosion caused by moisture and oxygen. It is important to check the drain pipe periodically to ensure it is free of debris. If it is clogged with rust, you can use a rust converter to coat the rusted areas. You should allow the converter to dry completely before attempting to repair the drain pan. If the rust converter is applied improperly, the repair will fail quickly. Another option is to use a sealant to repair the rusted areas. However, it is recommended not to use silicone-based sealants as they may not adhere properly to the rusted drain pan. 

Rusty drain pans are difficult to repair since they are made from thin-gauge galvanized steel. If the pan is rusted beyond repair, you may want to replace it. Some drain pans are built into a fixture, making it impossible to remove the pan if it is corroded. You should also make sure to shut off the electrical power and fuel line before starting any repairs. 

Broken condensate pump 

If you have an air conditioning unit in your home that is leaking water, it could be due to a broken condensate pump. This component is located above the air conditioning unit and is designed to remove excess water produced by the system. When the water level in the condensate pan rises, the condensate pump will activate and drain it outside of the house. However, if your condensate pump is not working, the water may collect inside the condensate pan and spill out into your home. If you notice water leaking from your AC, it is time to call a contractor who can repair the problem. 

The first step in repairing the broken condensate pump is to unplug the unit from power. Next, you need to open up the unit and check it for dirt and debris. In addition, you should also check the pump for cracks and other signs of wear. Once you have checked the pump, you should replace it if needed.
