Do Air Conditioners Use Water?

Do air conditioners use water? The straightforward answer here would be no. All air conditioners do not use water.

But that is a rather generic answer since some air conditioners use water.

Read on to get better informed on what types of air conditioners use water and those that do not use water.

One of the most revolutionary inventions is the air conditioner. From a general perspective,many people hold that air conditioners use water.

When you observe an air conditioner, you may discover that it may leak some drops of water. Still, at the back of the air conditioner, it is common to notice dripping water.

This has been interpreted as the truth that conditioners use water. This is a straightforward assumption since it is not entirely true.

Which Air Conditioners Use Or Do Not Use Water?

Commercial air conditioners use water. On the other hand, residential air conditioners are not designed to use water.

Talking about the use of water in commercial air conditioners, it is not as simple affair as it may seem.

Indeed, water use comes with additional costs in maintenance and operational costs for the air conditioners.

Do air conditioners use water? The straightforward answer here would be no. All air conditioners do not use water.But that is a rather generic answer since some air conditioners use water.

Additionally, the installation of the same air conditioners is more costly due to their make-up to use water.Consequently, these are not cost-effective to be used in residential homes.

The air conditioners that use water come in three types.

First, there are  some that need water for use, there are the shell and coil,there are tube-within-a-tube, and lastly, we have the shell and tube.

These units are different in design.Their common similarity is water usage.

However, in terms of efficiency, these commercial air conditioners are regarded as the most efficient. They far outweigh what you can get from a regular air conditioner.

With the tube within a tube, it has a smaller tube inside a larger one.They are coiled for saving of space, and they are very useful in that aspect.

When it comes to the operation,water passes through the smaller tube, cooling the refrigerant in the larger tube. This refrigerant also passes in its tube continuously.

This being the cheapest method to produce, it is the most desired air conditioner as it multiplies the heat between the two tubes.

Regarding the shell and coil, this is ideally a coil that has an outer shell. The coil is made of copper.

The copper coil inside processes the water. It, therefore, creates a cooling effect.

The refrigerant enters the shell via the top. As the refrigerant passes through the shell, it gets cool to the extent of being condensed at the bottom.

Lastly, there are the shell and tube air conditioners. This consists of a shell that acts as an enclosure for several copper tubing.

The appropriateness of this method is only in mega capacity units.

What Is The Difference Between Modern And Old Air Conditioners?

As the cooling process, some air conditioners use evaporation. By default, these are the conventional ones.

However, many modern air conditioning units do not rely on water.

 For most modern air conditioners to function, they merely compress air. On compressing air, the air gets heated up. After the air is decompressed, it will just cool down.

Therefore, most modern air conditioners have compressors. Just like other air conditioners, there will be a by-product from the process.

This by-product is water, and it can be seen as drippings from the window units.

All in all, modern air conditioners are different from older air conditioners. However, the difference is not largely on the build-up but the efficiency.

Do air conditioners use water? The straightforward answer here would be no. All air conditioners do not use water.But that is a rather generic answer since some air conditioners use water.

Indeed, modern air conditioners are cost-effective to run, unlike the older ones that used too much energy.

Again, there are Eco-friendly products in the category that can make a difference in your heating and cooling needs.

How Much Water Does an Air Conditioner Use?

A water-cooled air conditioner can use up to 720,000 gallons of water per year. This may seem like a very large quantity of water.

However, the residential air-cooled systems require more when it comes to pushing out.

They also use over 250,000 kWh in energy. This shows that the more economical option would be the air conditioners that uses water.

Therefore, the home air conditioners will use too much energy to heat the home.

Regardless of that, they are still the best option for a home since the water-using air conditioners are too costly compared to these in a home establishment.

Do You Need Water for Air Conditioning?

You do not need air water air conditioning for residential use.

Indeed, it is okay, even cost-effective, to continue using the air-cooled air conditioners for residential purposes.

However, due to innovations over the years, it is possible to get water-cooled air conditioners portable. These are designed for home or residential use.

It is a worthwhile investment to consider them. In their functioning, they will transfer heat to water after forcing it from an area.

After this, the heat is processed through the drainpipe, and the unit gets water distributed to it via a flexible hose.

The hose is directly connected to either a tank or any other source of water.

These innovations are meant for utilization, unlike their larger counterparts that are best utilized in large spaces.

Not very uncommon, some businesses use the portable versions of water air conditioners in server rooms.

These are rooms whose temperatures can go beyond 100 degrees.

When using these devices, you only need to ensure that all spaces are sealed. Complete sealing is required.

It is very easy for the cool air to evaporate as they don’t use an evaporator coil for cooling the air.

Is There Any Danger Attached To A/C Water?

You may wonder how useful or safe is the water that leaks from an air conditioner.

You may also want to know if it can be used for other purposes. Re-purposing items has become the trend today.

This is due to the scarcity of resources. Those who want to be more efficient will try to figure out ways of reusing literary anything.

The biggest concern at hand is, can AC water be harmful?

Most undoubtedly, water dripping for an A/C unit will contain some form of bacteria. It is easy for the unit to be clogged or develop mold.

Although the water is not stagnant, it may contain bacteria and is therefore not advisable to use such water for drinking purpose.

However, there are safe ways of using this water. For instance, it can be used to water gardens or for washing floors.

When it comes to using air conditioning water for watering plants or gardens, it may contain some chemicals.

For instance, if there is a cleaning treatment that has been performed on the unit, it is not safe to use this water for watering any plants.

The chemicals may be harmful to your plants. It is important to remember that chemicals can last for as long as two weeks in or around deposits of water.

Why Do Residential Air Conditioning Units Leak Water?

As already explained, AC units found in our homes do not use water. Therefore, it is essential to understand why they leak water, although they do not use water.

To produce air, residential air conditioning units use an evaporator coil for cool air production.

This is unlike their counterparts, the industrial air conditioners, which use water.

All warm air passing through the coil ends up being cool to the point of turning into water. This condensation is what occasions droplets of water.

In normal circumstances, the back of the unit will be the appropriate exit route for the water (condensed hot air turned into water).

Note that, however, the water may also leak from inside of the home due to a malfunction of the unit.

Some myth has it that the reason for this water leaking from inside is because the air conditioner is not well tilted. This is wrong. Indeed, it is a misconception.

This problem arises from the clogging of the condenser drain line. As long as the line is clogged, the water cannot escape from anywhere else but through internal leaks.

Removing the clogging does the trick and sends the water back to where it belongs.

There are various causes of clogging. However, the main cause that is too common is when there is a significant build-up of dirt, mold, and dust.

Mostly, this can be addressed by a thorough cleaning by a trained professional.

How Much Will I Pay To Have My Clogged Line Cleaned?

Due to the complexities associated with the Air conditioning unit, it is not possible for anyone to safely clean the unit.

Indeed, this is a task that may require a trained professional to handle.

There is too much associated with the drain, and it is not easy to be drained without proper knowledge.

Although there may not be many things to do, this ends up being a tedious process in the long run. As a consequence, it is best to leave this task to a trained professional.

It is highly recommended that you hire a professional to have your AC unit cleaned. Although prices may vary, they may not greatly deviate from an average of $200.

With about this much, you will easily find qualified personnel who will perform the task.

Although the water generally comes to the window units in a residential setting, it is also possible to see the water in the house.

The price seems a little prohibitive. However, it is best to keep our appliances running at their best.

This way, you will be able to enjoy the efficiency of the appliances.

Failure to fix this on time may end up damaging other parts of the unit or other accessories in the house or flooring.

There is also a wise way to avoid clogging. If you have your AC unit maintained regularly, it will never clog and occasion higher charges.  

Indeed, it is always naïve to assume that electrical appliances are meant to be plugged in and function. They need to be maintained to stay in top gear.

Without regular maintenance, it will be hard to enjoy their functionality. What’s worse, it may break down at the time you need them.

Concerning air conditioners, there is a considerable part that is played by water, especially in the commercial air conditioners.

Without water, these powerful machines would be uncommon.

Do air conditioners use water? The straightforward answer here would be no. All air conditioners do not use water.But that is a rather generic answer since some air conditioners use water.

It is a good thing for homeowners to assimilate the fact that water does not make part of their air conditioner’s make-up.

Indeed, the overall functioning of residential air conditioners does not have much to do with water.


Air conditioners have become part of many people’s lives. Indeed, some people can’t imagine how life would be without these wonderful devices.

The invention of air conditioners saw many problems solved, not only in the residential setup but also in the commercial setup.

The fundamental functional and design of residential and commercial air conditioners are different.

While residential air conditioners do not use water, commercial air conditioners use water.

However, although residential air conditioners do not use water, they also produce some drops of water.

The water from both commercial and residential air conditioners should be reused with caution.

It should never be used for drinking, but if it is used for watering plants, you need to be sure that there are no chemicals that were recently used to clean the air conditioner.

When your air conditioner gets clogged, ensure that it is addressed by a trained professional.

This will be the best way to steer away from other dangers associated with the poor handling of your air conditioner.

It is needful to understand that, although it may seem costly to have a professional unclog your air conditioner, this is the only viable way to be sure of professionalism and future safety.
