11 Reasons Your Portable AC Fills With Water Too Quickly

During the cooling process, portable air conditioners produce a significant amount of water.

Due to the fact that portable air conditioners employ the same refrigeration cycle as compressor-based systems, namely the vapor compression cycle, they are more energy-efficient.

Several factors influence the amount of water produced, with humidity being the most significant. A portable air conditioner that quickly fills with water, on the other hand, is a severe safety hazard.

Having to empty the condensate pan every couple of hours is a major hassle. It’s especially important at night when you’re exhausted after a hard day’s work and yearning for a decent night’s sleep.

11 Reasons Your Portable AC Fills with Water Too Quickly

The relative humidity in your area is the most important factor in why your portable air conditioner fills up with water so quickly.

If you have a blocked filter or condensate line, on the other hand, you can be experiencing an excessive amount of water deposit. Because of the obstacle,

the flow across the evaporator coil is slowed, resulting in ice that melts and fills the water container on a continual basis with water.

Self-evaporating portable air conditioners are available in a variety of models. This ensures that any excess water is removed as fast as possible via the ventilation pipe.

This technology, on the other hand, is not available on all portable air conditioner models.

However, although your portable air conditioner is capable of evaporating water on its own, the vast majority of air conditioners are only partly evaporative in operation.

This suggests that they still have a water tray on their table or counter. With the water tray, you may collect water that isn’t being released at the same pace that it is being generated.

The reasons can be broken down into 3 main categories. With our help, you will be able to solve your air conditioner problem.

2 Common Problems

Is Your Air Conditioner New?

Although it’s possible that your new portable air conditioner is leaking a substantial volume of water, it’s very improbable that the device is experiencing a technical malfunction.

This is due to the fact that air conditioner manufacturers are very concerned about their brand’s image. As a result of the intense level of competition,

they cannot afford to have their brand reputation tarnished.

It is possible to exchange a damaged or malfunctioning portable air conditioner if it was damaged or malfunctioned during the shipping process, however.

Although it is most likely due to the high relative humidity in your region, the issue might also be connected to the fact that you have just acquired a new computer and are experiencing difficulties with it.

As soon as the humidity in a room has been removed by the air conditioning system, it is removed from all surfaces in the space, including the floor, walls, ceiling, furniture, and other items in the room, as well as the air.

Depending on the circumstances, an excessively big volume of water may accumulate in the water pan, which might be hazardous.

As a result, if the water pan in your new portable air conditioner continues to fill, you should postpone returning it to the manufacturer for a couple of days before returning it.

It continues to fill, on the other hand, indicating either a defect with the air conditioner or that it is incompatible with the high average relative humidity found in your region.

As a result, you may want to consider a different kind of portable air conditioner, such as one that is powered entirely or partly by evaporation, as an alternative.

Is Your Air Filter Dirty?

When you switch on your portable air conditioner, it blows cooled air into your living space through an air filter. By employing the filter, you can prevent dust and other particles from entering the air.

It is necessary to clean the filter on your portable air conditioner after a set amount of hours. The duration of its operation is governed by the quality of the air it circulates.

One of the reasons your portable air conditioner is continuously filling up is a blocked filter. If your filter becomes clogged with debris,

the volume of air that can be exhaled by your portable air conditioner will be reduced. As a consequence, the airflow rate is reduced and less air passes over the evaporator coils.

As a result of the freezing process, the evaporator coils freeze the moisture in the air, which then drips into the condensate pan.

When using a partially evaporative portable air conditioner (one that evaporates water), the water will not be evacuated at the same rate as it drops, necessitating frequent emptying.

On the majority of air conditioning systems, a visible indicator indicates when the filter should be changed. This feature is activated when the filter gets clogged or after a certain period of time passes while the machine is operating.

The manufacturer defines the time period during which the filter reset light should be on after reset. Unless and until the filter is removed, cleaned, and then replaced, the portable air conditioner will not operate.

As a consequence, you should check for obstructions in the air filter of your portable air conditioner. The filter should be removed and carefully cleaned.

Because most air conditioner filters are washable, you won’t have to change them as often as you would otherwise.

Following air filter cleaning, it should be thoroughly rinsed with lukewarm water. Allow it to dry fully before reinstalling it in the machine.

Humidity Issues

Is There High Humidity In Your Area?

As a result of the condensation of moisture in the air, your portable air conditioner generates water, whether it is a little amount or a lot. The quantity of water that is created is proportional to the relative humidity of the air.

If you reside in a humid climate, the condensate pan of your portable air conditioner will collect an increased amount of water. According to the United States Department of Agriculture,

Louisiana and Texas have a typical relative humidity of around 75%. Given the fact that they are one of the most humid cities in the nation, this is an unusually high number.

As a consequence, if you live in one of these parts of the United States, or in any other analogous portion of the globe, you will find yourself emptying your water pan on a regular basis.

Especially in cities with low relative humidity, such as those in Nevada or Arizona, manual draining is quite uncommon (less than 40 percent ).

As a result, the majority of portable air conditioners in these locations are primarily evaporative, which means you may never have to worry about condensate buildup.

This is due to the fact that the vast majority of the liquid gathered is rapidly drained. If you’re thinking about purchasing a portable air conditioner, think about which model would be the greatest fit for you.

If you live in a low-humidity zone, you may use a portable air conditioner without self-evaporative technology since it will not cause you any problems with recurrent draining.

However, in very humid climates, it is advised that you use a portable air conditioner that is partly or totally evaporative in order to prevent constant interruption and aggravation.

Has The Humidity Changed With The Season?

The relative humidity varies greatly from one city or area to another throughout the whole nation. While this is true in most cases, it is dependent on the time of year in which your portable air conditioner is being used.

All year, certain days have greater relative humidity than others, and this is true regardless of the season.

As a consequence, it is possible that the significantly increased volume of water generated on certain days is just a seasonal phenomenon.

The seasons with the highest and lowest humidity levels differ from one state to the next and from one city to the next.

For example, September is the wettest month in New York, yet April is the least humid month in the city.

This implies that between September and April, your portable air conditioner will emit more water. July, on the other hand, is the wettest month in Nome.

In the event that your portable air conditioner begins to accumulate a significant quantity of water without notice, it is almost definitely not due to a change in season.

This is due to the fact that the weather’s influence on the humidity of the air is not impulsive. The variance in the rate of climb and decline is not statistically significant,

though, which is another plus. In this case, if your portable air conditioner produces a significant volume of water on a certain day, the most probable explanation is another issue.

What Is The Humidity Of The Room Your Air Conditioner Is In?

When the relative humidity levels in the region where your portable air conditioner is operating are very high, it is possible that it may overfill on a regular basis.

There are two situations in which your portable air conditioner begins to accumulate water at an alarming rate in this situation: first, when the temperature is too high or too low.

While moving your portable air conditioner from room to room, it has accumulated a significant amount of cool air. You continue to use your unit in the same location, but the amount of water that has to be drained has grown.

In the first scenario, it’s clear that the relative humidity has risen significantly in the new position of your portable air conditioner.

Increased humidity in your house, whether in the laundry room, kitchen, basement, or attic, or system failures such as inadequate insulation, cracked foundations, or leaking water pipes, might be the reason for this spike in temperature.

A clogged filter, faulty components, or blocked coils are all possibilities in the second scenario, and the cause of the issue is almost certainly internal to the device in question.

Assuming there is no internal fault, either the relative humidity surrounding the portable air conditioner is much higher than normal, which might be caused by any of the problems listed above, seasonality, or a combination of these two factors.

Inquire as to what is causing your unit’s very excessive water buildup. Following that, inspect the room where the portable air conditioner is operating for issues such as damaged pipes, limited ventilation, or water leaking into the building.

Mechanical Problems

Is Your Condensate Pump Functional?

Installing a condensate pump is a straightforward method of completely eliminating condensate. Typically, the condensate pump is used to transport the water collected in the water pan to a specified destination. It’s a really simple process to get started.

Even though you have a condensate pump, if you notice that water is seeping out of it or that your water tank is always full,

there is a good chance that the condensate pump configuration is improper.

11 Reasons Your Portable AC Fills with Water Too Quickly

There are two possibilities: either the condensate pump is not working properly, or the drain line connecting to or exiting the pump is obstructed or bent. Water flow is impeded as a result of this.

It is advised that the pipe running before and after the condensate pump be inspected for damage. If you haven’t used a condensate pump before,

you should consider doing so, especially if you’re tired of your portable air conditioner running out of coolant at the worst possible time.

In terms of installation, it is quite basic. It is only essential to connect the drain line to the condensate pump and the air conditioner at this point in the process.

Condensate pumps are powered by electrical current. You may expect water to continue to accumulate in your condensate pump until a particular threshold is reached.

As soon as that level is achieved, the pump automatically begins to operate and delivers water to the designated place.

The water may be removed without the use of a condensate pump by rerouting the drain line to the outside. Keep in mind, however, that gravity is required in order to do this.

Because of this, this technique will fail if the water must flow in the opposite direction of gravity, as is the case in several situations (upward).

The solution to this issue is a condensate pump, which propels water against gravity to a different part of the system.

Does Your Water Drain Properly?

Manually draining your portable air conditioner is the quickest and most convenient alternative. Firstly, remove the drain stopper from the device and allow the water to flow into an appropriate container. Secondly,

How often you must do so is dictated by the humidity levels in your house and the length of time your air conditioner is in operation. It may last anywhere from six to eight hours and as long as several weeks.

Using this easy procedure, you may manually empty your toilet and be warned if there are any difficulties. For example,

the water tank of your air conditioner may suggest that it is full, but when the drain stopper is removed, no water drains.

One possibility is that the water tank’s drain has become clogged, preventing the water from escaping. Nothing could hinder it from the inside,

hence it must have been clogged from the outside while it was unprotected.

If you utilize a drain hose or a condensate pump to automatically remove water from your portable air conditioner, you should never have to worry about your water tank being full. The most often seen reason for this is a clog in the drain line.

Visually examine the drain tube for bends, particularly 90-degree bends, and make any necessary repairs. Additional considerations should be given to the line following the condensate pump if one is used.

Is Your Air Conditioner Blower Fan Functional?

It is vital for the effective functioning of your portable air conditioner fan that the airflow rate remains constant. It is the fault of a defective fan that either operates at an inadequate RPM or is completely inoperative that causes the freezing of evaporator coils.

Indeed, the lower airflow created by a faulty fan prevents the device from releasing enough heat from the evaporator coils, resulting in overheating.

As a result, ice accumulates on the coils, causing the portable AC compressor to be temporarily shut down until the ice melts away completely.

As the ice melts, the condensate pan fills up with water at a quick pace.

When a slow-running fan is utilized during this time period, ice melts at a rather slow rate. It is possible that once the ice has melted and the compressor has been restarted, a defective fan will cause the evaporator coils to freeze once again.

This procedure will be repeated many times, causing your air conditioner’s cycle to run longer than it should. When it comes to portable air conditioners,

a low RPM fan is especially wasteful since they operate mostly via evaporation. This group accounts for the vast majority of the units available on the market.

This is due to the fact that partially evaporative portable air conditioners vapourize the bulk of the condensation water produced by the unit. Under normal conditions, they seldom need to be emptied.

When the ice melts, the rate at which water accumulates in the pan will be larger than the rate at which water is ejected from the pan.

So even if you are running a self-evaporative portable air conditioner, you will have to empty it many times during the day.

Let’s take the blades of the blower fan of a portable air conditioner as an example of this. The airflow rate will be lowered if they are damaged,

even if the engine is running at an adequate RPM. In this case, you must replace the fan with a model that is functionally equivalent.

It is possible that the fan motor is to blame for the incorrect fan RPM setting. Reduced rotational velocity leads to a reduction in airflow over the surface of the instrument.

On the motor, short circuits, continuity difficulties, and other flaws must be looked for and repaired as necessary. If the problem is minimal, you may be able to get it resolved.

It is also possible that the faulty functioning of the fan is caused by the presence of extra electrical components such as a switch, relay, or control board. When they are diagnosed, they will need to be replaced with the exact same model and kind of device.

If you are inexperienced with the diagnosis of electrical components such as motors, circuits, or circuit components, it is highly recommended that you seek the assistance of a qualified specialist.

If this is the case, the only thing left to do is look for clear and glaring defects in the system design. Your safety is of the utmost importance.

11 Reasons Your Portable AC Fills with Water Too Quickly

Are Your Evaporator Coils Clogged?

Your portable air conditioner is equipped with coils that may be used for both heating and cooling. The terms “condenser coils” and “heating coils” are often used interchangeably in the HVAC industry.

Cooling coils are often referred to as evaporator coils, which is a common abbreviation.

During the process of passing through the evaporator coils of the device, the air is cooled. Aside from that, these coils are capable of condensing water from the surrounding air.

In order for air to flow, the coils on portable air conditioners must be clean and clear on both the condenser and the evaporator sides.

If, on the other hand, your portable air conditioner overheats, the evaporator coils are most likely the root cause of the problem.

When the coils of a portable air conditioner get clogged, less air can move through them. As a result, the airflow rate drops to an excessively low level, which is unacceptable.

As previously noted, it is necessary to maintain appropriate airflow across the evaporator coils. As a consequence of insufficient ventilation,

ice forms on the surface of the water tray, which melts continually and repeatedly fills the water tray.

The solution is straightforward: you must maintain your coils in the same manner as you do your filters.

In general, you will need to clean portable air conditioning coils considerably less often than you would need to clean air conditioning filters.

But they will grow filthy regardless of how long they are exposed to the elements.

Using a sufficient brush, carefully brush away dirt and grime in an upward and downward motion in an upward and downward direction.

After that, clean the coils of your portable air conditioner using a solution of warm water, soap, or dishwashing liquid.

What Is The Capacity Of Your Air Conditioner Condensate Pan?

One reason your portable air conditioner condensate pan or water tray fills up so quickly is that it has a little capacity.

Obviously, a smaller condensate pan will accumulate more condensation than a larger one, needing more frequent emptying.

However, it is probable that the little condensate pan on your portable air conditioner is generating further issues. When they are combined,

they may be causing you to constantly empty your unit to the point of discomfort.

For instance, imagine your portable air conditioner’s coils freeze owing to a variety of factors, including a dirty filter, clogged coils, or a damaged fan.

The ice melts and the condensate pan rapidly fills. You’ll need to drain it regularly.

Additionally, a condensate pan with a small capacity will worsen the already high rate of water entry caused by ice.

It will fill up much more quickly and you will have to empty it more often.

As a consequence, I would recommend that you check for the other concerns mentioned in this article before assuming that the cause is your portable AC’s decreased water holding capacity.

You may always use a drainpipe to bypass the condensate pan and remove water automatically.

If you need to evacuate water against gravity, i.e. from a height above your unit, a condensate pump will resolve this problem permanently.

You will never have to empty your unit’s condensate pan again. You may examine the specs for my favorite condensate pump by clicking here.

Is Your Water Level Indicator Functioning?

More components are involved in the condensation process of your portable air conditioner, either directly or indirectly, than you would think.

The words “wet switch,” “float switch,” and “water level indicator” are all slang terms for the same piece of equipment. It is in charge of determining the actual water level in the water container for portable air conditioning.

Wet or float switches may malfunction, be poorly installed, or be misplaced, causing the portable air conditioner to get an inaccurate signal regarding the water level in the reservoir.

Consequently, the portable air conditioning unit will shut down far more rapidly and will need to be emptied even before reaching its full capacity.

When a water level indicator is inaccurate, the diagnostic is quite easy. When the device indicates that the container has to be emptied, check the water level. This method should be repeated as many times as necessary.

It is virtually guaranteed that a wet switch will occur if the condensate storage tank’s entire capacity is not being used.

Frequently Asked Questions

Is it Safe to Leave Portable Air Conditioning on All Day? 

Yes, you can leave your AC on all the time. However, you should bear in mind that this can increase your energy bills considerably. 

Should I Buy a Portable Air Conditioner?

Yes, you might want to invest in one of these products if you want to keep your home cool. Because they are portable, these AC models can be carried from location to location as needed. Plus, they are very cost-friendly.

Final Thoughts

The pace at which your portable air conditioner depletes its charge during the day is determined by a variety of variables.

It varies according to the humidity level, the length of time the portable air conditioner is used, and the kind of portable air conditioner utilized.

If you have a self-evaporative air conditioner, the majority of the humidity is quickly evacuated via the vent during warm air exhaust.

The majority of portable air conditioners on the market use self-evaporation technology. Portable air conditioners, on the other hand, are categorized into two categories: partially evaporative and entirely evaporative.

The majority of portable air conditioners use both evaporative and convective cooling methods. As a consequence, if you just got a portable air conditioner and are unsure of its kind, it is almost definitely evaporative in nature.

The majority of portable air conditioners on the market use both evaporative and convective cooling methods. They vanish spontaneously. They will, however, not completely eliminate the moisture that has collected throughout the cooling process.

They must be drained often, depending on the humidity level of the air, unless one of the other issues mentioned before occurs.

Completely Evaporative In terms of humidity removal, portable air conditioners are totally self-contained. Choose this one if you wish to keep absolutely clear of trouble.

In summary, there are several reasons for your portable air conditioner’s excessive water production. The relative humidity is the principal cause of water buildup.

However, other elements may be modified, such as a filthy filter, a defective condensate pump, or blocked coils. Give them a once-over to ensure there are no moisture issues.

Additionally, carefully choose your portable air conditioner based on your location’s environment. If the humidity level is too high and your portable air conditioner is not successfully expelling moisture, make changes such as draining through a hose or a condensate pump.
