Why are the Air Conditioners Leaking Water Inside? 7 Common Causes.

Why are the Air Conditioners Leaking Water Inside? 7 Common Causes. 22 Jan

Air conditioners provide cold air in your home by removing heat from a space within your home and taking it outside. The cool air is expelled via ventilation in the building. Air conditioners are the best devices for creating a cool and conducive environment in a home. Air conditioner leaking water mostly happens when the drain gets clogged with dust, dirt, sludge or mould.

In this case, humidity and temperature fail to be controlled. In this article, you will know why your air conditioner is leaking water and why you should hire a professional to repair the air conditioners.

Why Is My Air Conditioner Leaking Water?

Your air conditioner may leak due to the following reasons:

Frozen Evaporator Coil

When refrigerant in an AC unit no longer takes in heat from the space in coverage, it results in a defect that causes warm air accumulation. The whole unit should be turned off to allow the evaporator coil to become defrost to resolve this problem. You need to turn on your AC after the coil has returned to its normal state.

Some measures can be taken to prevent the evaporator coils from being frozen out. It is done by changing the air filters every month or at least once in three months. You should be very careful when handling the vents, as a covered air vent may result in the blockage and freezing of the coils. In this case, an expert technician should be called as the refrigerant charge may be low. The air conditioner evaporator coil leak requires the services of a professional technician.

Things to let you know when you’re low on refrigerant: When you hear a hissing or bubbling noise (indicating a refrigerant leak) or when the room is not cooling. Depending on the severity of the air conditioner evaporator coil leak, you’ll either have to repair the leak or change the whole AC unit. Installing a new AC unit may be an expensive option, but it is the best way to fix this problem.

Cracked or Overflowing Drain Pan

The air conditioner leaking water implies that the drain pan is overflowing or cracked, in this case, be sure that your air conditioner is damaged and is probably leaking water. The drain pan is usually connected to a pipe that serves as an outlet for condensate collected from the AC. The drain pan is just beneath the air handler and is responsible for discharging condensation from the air conditioning unit. In case of a leak, the unit should be turned off and inspected for an overflow or crack.

This can be temporarily fixed with a water sealant. Replace the damaged item to avoid another breakdown of the same. Make sure to use a wet-dry vacuum to clean the overflow pan and check the drain pan’s edges and corners.

There are usually two drain pans – one is located underneath the evaporator coil, and the other is underneath the unit. Replacing the damaged drain pan by yourself can be a troublesome job. You will have to hire an expert for the job since it requires professional skills to do it properly.

Clogged Condensate Drain Line

When the drain is clogged, it leaks air into the air conditioner. Also, an overgrowth of algae and fungi may cause the clog. Inanimate substances like debris could also be the culprit. Given this problem, the condensate drain line should be inspected frequently and cleared as necessary. This will also ensure that your device is clean and maintained in good condition for use.

Damaged/rusted drain pan

Rust causes a lot of damage to the drain pan and is likely to form because most air cleaners react with oxygen and water. An old air conditioner that is 12-15 years old may have the drain pan damaged or rusted through. In this case, you’ll need to replace the pan. Greasing the surface cannot fix this because the device is already faulty. Only buying a new one can be the most long-lasting solution to this problem.

Broken Condensate Pump

Condensate pumps are often fitted to pump water outside. They are more likely seen in AC units installed in enclosed spaces with little ventilation (outlets) or basements. A break in the pump will result in the flow of water, as the water will not be pumped outside. To solve this issue, call a professional technician to replace or repair the broken pump.

Dirty Air Filter

When the air filter is dirty, it stops airflow through the evaporator coil. When this happens, the evaporator coil gets too cold and freezes over. Filters with high temperatures are likely to melt an excess amount of water that the pan may not be able to handle. Always check your AC’s air filter to see if it’s dirty. This will save your machine from a sudden breakdown.

Air Conditioner Compressor Leak

Exposure of air conditioner compressors to extreme heat for an extended period can cause them to leak. A count of other factors could result in a leak from the air conditioner. Consequently, evaporator coils become frozen out, and water imminently overflows the drain pan. Proactive measures should be taken to call an expert. Allowing a leaking system to run could cause an air conditioner compressor leak, necessitating avoidable expenses.

Conclusion

To conclude, just like any other home appliances, air conditioners are also susceptible to getting damaged and malfunctioning. It is essential to regularly examine your appliance to ensure it is working well and without faults. This will help you to maintain your system and ensure it’s working amidst all odds.
