Fixing Water Leaks on your AC

Fixing Water Leaks on your AC

Places with warm weather commonly experience aircon water leaking. This is due to the excess water facilitated by the heat coming from the environment. You can see this when you go outside to check your AC and you see an abnoramally large puddle of water which looks like you left the faucet on for more than a few seconds.

A leaking AC is a commonly reported problem to air-conditioning service providers. Some leaks go unchecked because they are minor and can be neglected. However, it can grow to a bigger problem if not addressed earlier.

Air-conditioning units that are dripping water will not only damage your unit but it can also seep into wood furniture or panels that cause it to break or go soft. This can get dangerous especially if it is part of the structure of your home.


AC leaks are due to a crack inside the piping of your machine or a hole in the drain pipe. It causes the water to seep out getting exposed outside. You can mostly see it with the pipes dripping out too much water.

You can check you drain pan by using your flashlight. If you suspect that your air-conditioner is leaking water more than the normal volume, then, it may be time to inspect the drain pan because it might be overflowing.

Examine the drain pan thoroughly from all sides. The corners and bottom would be a good way to start. You can also see where the leaking water is coming from and trace it back to the pan. An epoxy adhesive will be good enough to fix a problem such as this.

Clogged filters

Clogging inside the drain is caused by continuous operation where particles such as dust and debris get stuck inside the pipes. This causes water to get trapped inside causing the aircon not to blow cold air and produce excess water inside the unit that will eventually leak out from the machine casing.

Regular maintenance work such as changing the filter will usually help you avoid this problem. A clean filter will be better in keeping dirt from entering your room and it will keep water from building up due to the unnecessary heat.

For the summer, it would be best to clean or replace filters every month. The build-up of dirt will be faster during the summer because the AC works harder due to the hotter environment. Prevent ice forming on your evaporator coils which will cause the water leaks and dripping.

Condenser build-up

The condenser is an important part of the cooling process and the end-product is water. If there is a build-up inside the condenser, the water produced will be in excess because the heat the condenses the refrigerant will produce more volume of water.

Blocking in the condenser line will cause the water in the drain pan to also overflow. Smarter AC units now have a mechanism where it can detect a blocked condenser which triggers an auto-shutdown mechanism.

It keeps water from damaging your AC which in turn will keep it running optimally for longer. You can clean these clogs up by using a vacuum specially made for cleaning AC’s. These have a pump mechanism that you can do manually with your hands that will help clear the condenser.

All the specific problems can be fixed earlier if you follow the steps outlined above. Once you notice signs of a leak, don’t hesitate to perform these DIY aircon maintenance methods. If they fail, consult a professional ac repair contractor.
