What is a portable air conditioner?

If you need to chill a single room, a portable air conditioner (PAC) may be your best option. They are normally placed on the floor and come with an installation kit for a quick and easy installation. If you’re looking for something that can be moved around the house, a portable air conditioner might be just the ticket.

How to Drain Your Portable Air Conditioner in Easy Ways

Why Should People Drain A Portable Air Conditioner?

As temperatures soar, your portable air conditioner has proven to be a necessity. As a result, you’ve been able to enjoy a more comfortable and peaceful environment.

It has kept you cool and comfortable all this time. As a result, it is only reasonable that you take care of your air conditioner as well. Why does that happen? When an appliance is not properly maintained, it will malfunction and fail to perform at its best. In the same way, a portable air conditioner falls under this category.

There are numerous problems that can arise if you don’t drain their portable air conditioner.

Problem #1. Your portable AC will not run

When the water level in the tank reaches a predetermined level, most portable air conditioners automatically shut down. When this happens, the air conditioner’s alert will tell you to begin draining. If you don’t do this, your portable air conditioner may stop working.

Problem #2. The water on your air conditioner’s tank will overspill

Overspilling is another possibility if you don’t empty your portable AC. If your air conditioner’s switch isn’t working, water will keep filling the tank until it overflows.

This issue could lead to additional problems, such as the damage that would be caused if your home were to flood.

Problem #3. Your portable air conditioner will be a habitat for molds

Imagine finding mold growing in your air conditioner. Imagine having to deal with molds like these. It is a filthy and time-consuming process. As a result, you must empty your air conditioners in order to avoid this. If you don’t drain your portable AC, it will accumulate moisture and serve as an ideal breeding ground for mold.

Knowing How Many Times You Have To Drain A Portable Air Conditioner

Is it necessary to empty a portable air conditioner on a regular basis? The draining interval for portable air conditioners is typically eight hours. However, there are specific situations in which it is acceptable to deviate from this rule.

Situation #1. When you are in an arid area

When you’re in an arid area, you don’t have to drain your portable air conditioner every eight hours. What exactly is going on here? It is impossible for the portable air conditioner to draw moisture from the air when it is operating in high humidity. As a result, the water will be drained from the system.

Situation #2. When your portable air conditioner is up to date

Most modern mobile air conditioners use vents to remove moisture from the air in your house. During the process of accomplishing this, water from the AC’s tank is transferred to the AC condenser coil, where it reacts with the condenser coil and becomes vapor. In other words, your tank would be devoid of any water.

However, if you live in a humid environment, this may not be the case. Even if you have a portable air conditioner, you still need to assess it because there is a chance that water will get into your tank.

Reasons Why A Portable Air Conditioner Generates Too Much Water?

Cooling your home with a portable air conditioner naturally generates water. But there are specific situations that cause portable air conditioners to produce more water than normal. Read on to learn why your portable air conditioner is taking up so much water.

Reason #1. Internal factor

One of the reasons is because of the activities you engage in at home that contribute to the buildup of humidity. Moisture increases when you cook, for example, or take a bath. When you have more people in your home than usual, their breath can contribute to the buildup of humidity in the air. As a result, you need to identify the cause of the problem and eliminate it.

Reason #2. External factor

Excessive water production in your portable AC might be caused by a variety of external reasons as well. The weather, for example, is an example. You must also control the amount of moisture entering your home if you want to reduce the amount of water your air conditioner produces. As a result, make sure to close all of your windows and doors completely.

How to Maintain a Portable Air Conditioner

Routinely Clean the Exterior

Cleaning the outside of a portable air conditioner on a regular basis is recommended.

The dirtier the exterior appears, the dirtier the inside components are likely to be as well.

Use a moist towel to wipe down the unit’s external case after cleaning the room or its furnishings and other fixtures. Don’t use any detergents or special liquids to clean the external casing, since these items may discolor it and/or attract future dirt and debris.

Always Replace and Maintain the Filters

Filters are the most critical part of keeping a portable air conditioner running smoothly.

The air conditioner’s filters play a critical role in how well it cools, and they should never be taken for granted.

They may not cost as much as the compressor or the refrigerant, but they play an important part in determining the quality of air that is circulated in the room.

When purchasing air conditioner filters, be sure to carefully review the care and cleaning recommendations. It depends on the product: Some require disposable filters, while others may be cleaned and reused.

Ensure that you receive the correct model number from the portable AC unit’s manual if your filter can’t be washed and you need a new one.

In contrast, washable filters can be reused numerous times with no effort. Afterward, submerge the gadget in warm water with a moderate detergent, and then completely rinse it.

After removing any clinging debris or dust with a soft brush, allow the area to air dry. Reinstall the filter as soon as it is dry.

More often than not, modern portable air conditioners come equipped with a pre-filter to keep the device free of larger dust and particle intrusions. The primary function of the pre-filter is to extend the life of the air filters within the vehicle.

Pre-filters should be cleaned at least every other week, if not more frequently.

When cleaning the pre-filter, use the same rule as when cleaning the exterior of the unit: do not use any cleaning chemicals or detergents. In many cases, the residue left behind by these items encourages the accumulation of even more dirt and particles, reducing the effectiveness of the pre-filter.

Routinely Inspect the Condenser Coils

When it comes to portable air conditioner maintenance, one of the most important aspects is ensuring that there are no components that are interfering with the unit’s functionality.

Filters can be replaced on a budget, however condenser coils are more expensive and require the expertise of a qualified technician.

Because of reason, it is essential to keep an eye on this part’s upkeep.

Over time, condenser coils accumulate grease and grime. Use a coil cleaner solution (available at most hardware stores) to remove any buildup that accumulates on this component on a regular basis.

You may save a lot of money and hassles in the long run if you do a little preventive maintenance on the condenser coil.

A new unit may be more cost-effective if your condenser coils need to be replaced.

Ensure the Exhaust Hose is Short and Straight

An exhaust hose is standard equipment on all portable air conditioners. As a result, the room’s temperature is kept cool.

This hose is designed to be as short and straight as possible in order to improve its efficiency, but most people are unaware of this fact.

They come up with all kinds of creative methods to stretch and bend the hose once they realize that it can be done.

Inefficient operation and reduced cooling capacity can be the result of kinks and bends in the exhaust hose when the unit is run at its longest possible length.

In order to prevent moisture buildup, an exhaust hose must also be short and straight. There’s a potential that moisture will leak back into the unit if it builds up inside the exhaust hose to an excessive degree.

Checking the length and straightness of the exhaust hose can be done in a matter of seconds. This problem must be resolved promptly if it is not already.

Be aware that the greatest portable air conditioners do not suffer from this problem.

Only Place the Air Conditioner in Clean Setting

The portability of portable air conditioners appeals to a lot of individuals. Some of these units can be relocated, either within a room or from one property to another.

Because of its portability, portable air conditioners have the potential to be problematic in the long run.

It’s common for a portable AC unit to be moved about a lot and not given much thought as to where it should be placed.

It is imperative that you avoid placing the device in areas that are prone to dust or filth. There is a risk of internal parts malfunctioning due to the accumulation of airborne particles and trash.

The item should not be used in a dusty or unclean room.

In addition, keep the portable air conditioner away from anything that could contribute to moisture buildup, such as a window. In extremely moist environments, this is the case.

If you have to use it in a humid environment, make sure to check the drainage pan more often. Draining it frequently will be necessary because of the water it gathers.

Store the Air Conditioner the Proper Way

Even though it sounds basic, many people overlook this maintenance tip when it comes to their portable air conditioners.

Do not leave a portable air conditioner near the window when you are not using it for a prolonged period of time (e.g. during the winter). Put it away in a cool, dry place where it won’t be exposed to extreme temperature swings or sunshine.

If you don’t use your portable air conditioner while it’s installed, it will collect moisture from the room and dust and grime from the air. It’s possible to have both of these illnesses and not know it.

Having read our article on the finest air conditioners for tiny rooms, many individuals assume that they can just plug in and switch off their AC unit in their basement’s spare room for most of the year. But the trust is, this same advice still holds true.

Turning on your unit and running it on fan mode is a smart approach to guarantee that it doesn’t have any moisture trapped inside before storing it. Then, increase the fan speed to its maximum level and let it run for a few hours at a time.

That will remove any remaining moisture from the structure.

Wrap the device with a large enough plastic sheet to completely cover it. Keep the portable air conditioner in a dry and cool location.

Wherever you spend the majority of your time indoors, a storage closet or similar space is ideal. This temperature is ideal for storing your portable air conditioner because it’s always kept here.

A Professional Check Up Can Be a Good Thing

Ask the expert to inspect your portable air conditioner as well if you have an HVAC system in your home and it needs to be repaired at some point.

While this guide’s maintenance advice can help you keep your appliance in good working order, there are some issues that only a trained professional can identify and cure.

A technician’s fast look for anything out of the ordinary could save you a lot of money in the long run on costly repairs.

If the expense of maintenance is prohibitive, you may want to consider replacing your current equipment with one of the more affordable portable air conditioners.


What is required to set up a portable AC?

Depending on the model, the setup process is short and painless. Air must be vented to another location–generally outside through an integrated window kit–because all portable ACs expel warm and damp air as they cool. An exhaust pipe can be attached to the window kit and used to vent the warm air outside. Some types can also be vented via a wall or into a drop ceiling. To begin cooling, simply plug in your air conditioner and remove the exhaust pipe and window kit.

How do portable air conditioners drain water?

A window kit exhausts the warm air that PACs remove from your air, and we know that PACs remove warm air and moisture from your air. However, what about the moisture?? The condensate water is handled in a variety of ways by PACs.

  • Advanced portable air conditioners have exhaust hoses that automatically remove moisture along with heated air. As a result, you will almost never have to deal with the condensate water that accumulates. Self-evaporative variants from brands like DeLonghi and Whynter are available, as well as Avallon portable ACs.
  • Attaching a drain line is another frequent method of removing accumulated moisture. Take use of the drain port’s water outlet by attaching an extension hose.
  • Portable air conditioners typically have buckets that need to be emptied every 8 hours to once a month, depending on the model. There may be times when you’ll need to turn off the device to empty the bucket and then re-insert it so that cooling can begin.

What size air conditioner (BTU level) do I need?

BTUs are the unit of measurement used by portable air conditioners, just like other forms of room air conditioners. Cooling power is measured in BTUs (British Thermal Units). These guidelines are used to classify our portable air conditioners:

  • If you have a room that is less than 300 square feet, a portable air conditioner with between 7,000 and 10,000 BTUs is ideal. Take a look at our selection of window air conditioners for compact spaces.
  • Large Rooms: This category of portable air conditioners is best suited for cooling rooms that range in size from large to extra-large. View our 11,000 to 14,000 BTU models if your room measures between 350 and 700 square feet.
  • This type of portable air conditioner is ideal for commercial and industrial settings, such as data centers, manufacturing plants, and venues for huge gatherings. Check out the models we have available for commercial use.

Can I lengthen the exhaust hose?

A portable air conditioner’s exhaust hose should never be extended. This could void your warranty and cause your air conditioner to overheat, depending on the manufacturer.

Why do portable air conditioners have to be vented outside?

You can use a portable air conditioner to cool your room since it removes heated air from the room. Getting rid of the heat is essential for a good cooling process. If you don’t vent the heated air outdoors, it will remain in your room and block the cool air from coming in.

Can I discharge the hot air out of a sliding glass door or sliding glass window?

Slider glass doors are more difficult to use for the purpose of venting portable air conditioners than regular windows. To fit sliding windows and sliding doors, standard window brackets are meant to be mounted vertically, rather than horizontally. Installing air conditioners in slider windows may necessitate some alterations to the window bracket.

It’s important to ensure sure the bracket is long enough to accommodate sliding windows. When it comes to sliding windows, units with twin window brackets usually do the trick.

What should I use to cool a server room?

To supplement cooling in computer server rooms or to provide the primary cooling source on weekends when the central air conditioning is turned off, portable air conditioners are commonly used. Portable air conditioners with self-evaporative technology are the best choice for these situations. As a result, you may leave the portable AC running unattended without having to worry about manually removing any collected condensation. Among the other things to think about are the following:

Ventilation can be difficult in server rooms because of the lack of easy access to windows and the possibility of them being inside rooms. You can use a drop ceiling or a hole in the wall to send the hot air discharge hose to a neighboring room as a solution.

I have a casement/crank-out window. Can I configure my PAC to exhaust air out of this type of window?

A casement window will not accommodate a portable air conditioner unit with a window kit. In order to cover their full window area, some customers have devised an innovative solution utilizing Plexiglas. For the hot air exhaust, they made a small hole in the Plexiglas.

What electrical requirements do portable ACs have? What about energy consumption?

There is no need for specialized wiring or outlets for most PACs, which are powered by standard home 115/120 Volts. It goes without saying that because air conditioners consume a lot of power, you should exercise caution when connecting numerous high-energy equipment to a single circuit.

There are certain portable air conditioners with greater BTUs (14,000 BTU and up) that may or may not require special outlets and wiring. If you have any questions, please refer to the product descriptions. Model and environmental circumstances can affect how much energy a vehicle uses.

Will a portable air conditioner work for multiple rooms?

It all depends on the situation. Portable air conditioners, like window-mounted air conditioners, are good in cooling their immediate surroundings. Cold air will not move down the corridor or through small openings. It’s likely that neighbouring rooms will feel a modest cooling effect if a room’s apertures are particularly large. Additional cooling can be achieved by using fans to circulate the air.

What is the difference between a single-hose design and a dual-hose design?

It’s possible that some portable air conditioners have only one hot air exhaust line, while others have a hot air input pipe as well.

  • Portable air conditioners with a single hose pull air from the room they’re in, cool it, and recirculate most of it. While cooling, a little amount of the air will be blasted out of an air conditioner’s exhaust port, which is where it will exit.
  • A single hose is used to draw in outside air, and the other line is used to chill the device itself. The second hose then expeles the hot exhaust air. There is, however, a price to pay. Dual-hose systems cool their compressors with warmer, unconditioned air, which reduces their efficiency. To compensate for their extra fan power consumption, they also have two internal fans.

Do I have to remove the screen from the window when using my window kit?

Portable air conditioner exhaust hoses do not extend out of the window for most of our customers, so they may leave the window screen in place. Make sure this is the case for you by reading the product description of the PAC you intend to purchase.

How loud are portable air conditioners?

The decibel range of most portable air conditioners is 40-60 dB. Portable air conditioner noise levels can be affected by a variety of factors, including:

  • Where the air conditioner is located in the room.
  • How fast the machine is running.
  • The AC has soundproofing or noise reduction features.

Wrapping Up!

Most air conditioners produce water as a byproduct. As a result, draining your air conditioners on a regular basis is recommended. That’s why this advice is ideal if you’re wondering, “How often do you have to empty a portable air conditioner?” You should know how to unclog your air conditioner drain if this happens since your drain might become clogged with dirt and dust.
