Why Do Air Conditioners Drip Water: Here’s How It Works

Air conditioners drip water mainly due to the condensation process that happens as hot air blows over the coils. And water dripping from your air conditioner is usually nothing to worry about. Most of the time, it is due to the normal functioning of your air conditioner.

However, if you notice excessive water leaking from your air conditioning system, it might be a sign of malfunction. If you notice that water is leaking from unusual places, it is also time to call your AC technician.

So, why does an air conditioner leak water, especially from unusual places? Here, you will learn why such a problem might occur and how to solve the problem.

Why Does My Air Conditioner Drip Water?

1. Leakage of Air

Generally, air leakage happening in the vent can lead to water leakage. When the air passing to the vent is lost in the process due to leakage, the air conditioning unit will not function optimally.

The best way to know if there is a leakage happening is to physically inspect your system.  You can also do the standard troubleshooting to determine the leak source. It is advisable to call an AC technician immediately if you suspect that your system is leaking.

2. Poorly Functioning Condensation Pump

Every air conditioning unit has a condensation pump that is responsible for draining excess water. The condensation pump is located below the coils, and it is supposed to pump out water from the system.

Unfortunately, sometimes the condensation pump might break or malfunction due to dust. When this happens, you will notice water leaking from your AC unit.

3. Dusty and Blocked Filters

The filters in your air conditioning unit are responsible for the proper flow of air in the system. Unfortunately, they become dusty and get clogged with dirt over time.

When the filters are dirty, the proper flow of air gets altered, and the system becomes warm. The warmth in the system leads to the melting of any accumulated ice that turns into water. You will notice a lot of water dripping from your unit if this is the case.

4. Lack of Regular Servicing

It is advisable to service your AC unit not less than twice a year. Lack of servicing leads to the accumulation of dirt in the system and other problems.

Regular servicing is important to ensure that everything is working as expected. When the unit is not working, as usual, it is likely to cause problems such as water leaking from the unit.

5. Clogged Drain

The condensate drain is supposed to get rid of water in the air conditioning unit. Unfortunately, it sometimes gets clogged with dirt, mold, and debris.

When the drain is clogged, it takes a lot of time for the water to drain. The excess water that does not drain ends up leaking from the system.

6. Poor Installation

If your air conditioning unit is poorly installed, you are likely to experience water leaking. Poor installation means that the unit is not properly set up to get rid of water.

In most cases, it leads to an accumulation of water in the unit which eventually leads to leakage. It is advisable to always get professional installation by a qualified technician.

7. Extremely Low Temperatures

Sometimes when the temperatures are extremely low, it is not unusual to experience water leaking from your unit. This is usually caused by a frozen air conditioning unit.

You will notice that your system tends to drip water after a chilly night. This is not a cause for alarm because, most likely everything is working as it should be.

Why Does an Air Conditioning Unit Leak Water?

Now that we have figured out why an air conditioner drips water, it’s time we find out the best solutions to stop the problem and even prevent it in the future. Here are some solutions:

1. Change your Air Filters as Recommended

It is advisable to change your air filters as recommended. Regularly changing your filters will guarantee you a proper flow of air in the system.

With a proper flow of air, you do not have to worry about the system overheating and causing problems such as the hasty melting of ice.

2. Do Regular Servicing

Servicing your air conditioning unit isn’t something to gamble about. It’s a requirement! It is advisable to clean your coil condenser and other parts during the servicing.

Fortunately, your AC technician understands all that needs to be done, so you do not have to worry about it. Cleaning your system is important to make sure that everything is working accordingly and also to prevent unnecessary clogging.

3. Make Sure that the System is Professionally Installed

Buying a good quality AC system is one thing but making sure that it is properly installed is another thing. Always make sure that the unit is installed by a professional to help avoid issues like water leakages. The professional will ensure that everything is working according to its intended design.
