This coming summer season, if you are planning to purchase a more cost-effective and efficient portable air conditioner with better air quality and less energy consumption, you will have a lot of options.

However, if you are renting, travelling a lot, or just trying to save money, buying a portable air conditioner might be the best option. 

Portable air conditioners make it possible for those with low income to enjoy the luxury and comfort of an air-conditioned room, as these air conditioners can cool down a room if not the whole house. 

Let’s start from scratch and find out what a portable air conditioner actually is and what benefits it brings.

What is Portable Air Conditioner?

As the name indicates, a portable air conditioner can be carried anywhere.

This means it has a small size, all components packed in one, and no requirements for heavy and permanent installation. 

Yes, it needs ducts to exhaust the air out of the room and some power cables. 

But unlike other air conditioners like split system air conditioners or heavy-ducted air conditioning systems which require a lot of

work for installation and operation, it just needs a few ducts which you can carry from one room to another depending on your need.

How Do Portable Air Conditioners Work?

Portable air conditioners work by extracting the hot air from the room and using refrigerant, evaporating coils, a compressor and a fan; they cool down and dehumidify the air then throw the cool air back into the room while expelling heat outside using ducts.

The refrigerant changes its state from liquid to gas when in contact with high-temperature air.

This refrigerant is then passed to the compressor which increases its pressure, and the hot refrigerant is converted to cool refrigerant which again passes to the evaporator coils. 

These evaporator coils decrease the temperature of the air and here again, the refrigerant changes its state and the next cycle starts.

The cool air is thrown into the room after filtration.

Calculating Cooling Capacity You Need

One problem that most of us face is that we don’t know how much cooling capacity our rooms require. 

For that purpose, we need to have the exact area of the room where we want to place or install our portable air conditioner. 

Now that you have the area of the room in square feet, you can calculate the BTUs of the cooling capacity of the air conditioner that is required. 

For that purpose, a chart is given which can help you in estimating the BTUs.

Benefits of Portable Air Conditioners

Easy Installation

Central air conditioning systems require heavy equipment and space for their installation with various ducts. 

Only expert technicians can install such air conditioning systems, and the installation is permanent. 

Even split system air conditioners also require some permanent installation on the wall.

But with portable air conditioners, you are free from such constraints, as their installation is quite simple and doesn’t require expert hands. 

While other air conditioning systems cool down the specific rooms where the systems are installed, portable air conditioners can be moved  from one room to another and can easily be installed.

If you are renting, it’s convenient to have an air conditioner that you can carry with you wherever you move, and for that purpose a portable air conditioner might be a good choice.


The biggest advantage of buying a portable air conditioner is the ease of moving it from one to another place. 

While central air conditioning systems and the other split system air conditioners are permanently installed, portable air conditioners can make your life easy if you want to move from one room to another and even if you are planning to change your home or apartment. 

With their reasonable size and weight, they’re easy to move and install all by yourself with little to no help.

Require Small Space

The small size of the portable air conditioner is another advantage. 

When considering buying a portable air conditioner, many people worry about the need to allocate space for it but in reality, its size is reasonable and it requires little space.

This makes it more convenient and easy to carry from one place to the other. 

Window air conditioners also require small space but are very noisy.

People living in apartments are usually not allowed to install window air conditioners, and for this reason, the best option would still be to buy a portable air conditioner.

Less Expensive

In terms of cost, a portable air conditioner is a better alternative to central air conditioning systems or split systems air conditioners which are much more expensive. 

The central air conditioning system has to work harder to cool down the entire house which increases your energy costs and ultimately your bills. 

In addition, the installation and maintenance costs are higher for the central air conditioning systems.

To combat such higher costs, portable air conditioners are most effective. 

They not only save you high electricity bills and installation and maintenance costs, but also reduce your energy costs in the long run where you can save $360 per month to $100 per month.

Multiple Functions

Portable air conditioners have various built-in functions.

They can be used for both cooling and warming if you live in a region where you experience both summers and winters. 

Portable air conditioners also dehumidify the room in humid weather.

In addition,  these air conditioners also work as fans, so if you do not want to cool/warm your room, you can just turn on the fan.

Better Air Quality

Another benefit of buying and installing portable air conditioners is that you can get better indoor air quality. 

The filters in the air conditioner help in the filtration of air.

They remove dust particles, microorganisms and allergens which can cause real implications for asthma patients. 

According to the US Environmental Protection Agency, poor indoor air quality can have negative effects on health.

For this purpose, air conditioners should be cleaned and maintained regularly, too.

Take It For Road Trips

Do you love travelling but worry about hot weather? In this case, you could buy a portable air conditioner for your travels.

One huge benefit of buying a portable air conditioner is its mobility especially if you don’t stay at home for a long. 

If you are planning long road trips, you can carry it with you during your voyage.

Plus, it can also be placed and installed in a boat to your trips more comfortable. Have you ever heard of taking your air conditioner with you on long trips? 

Well, a portable air conditioner gives you that option.


When most people are buying and installing central air conditioning systems and split system air conditioners, you should also look at the option of portable air conditioners especially if you are looking to save costs. 

These air conditioners are best if you want to cool down only one or two rooms. They can help you save on electricity bills, installation costs, and space. 

Also if you have low income and cannot afford other conditioning systems, portable air conditioners are a more affordable choice.

All set for summer? Obviously, you have some sort of to-do list to go through before summer arrives. 

One of the priorities for many would be to install a cooling system in their home, room or work space. The different types of air conditioning systems each have their advantages and disadvantages.

But if you want to cool down a single room, you could think about getting a window air conditioner or a split air conditioner. 

Before buying one, you should know that a split air conditioner has higher efficiency and higher capacity than the window air conditioner. 

Starting from scratch, let’s explain what a split system air conditioner is, how it works, the types of split systems, the pros and cons, the installation and buying costs, and the cleaning process.

What Is Split System Air Conditioner?

The first question that comes to mind is “what is a split system air conditioner?”. The phrase ‘split system’ indicates that it is made of two separate parts. 

The bigger outdoor unit is placed on the outside wall, and the smaller inner unit is placed on the inner wall.

The outer unit handles the air and contains a compressor and the condenser, while the inner unit contains the filtration system and the cooling coil with refrigerant inside. 

These two units are connected with copper refrigerant tubing, an electric cable and a water drainage duct.

How Does Split System Air Conditioning Unit Work?

To understand how a split system works, we first need to know that different parts of an air conditioner work in a chain. 

Refrigerant is a chemical that readily changes its state from gas to liquid and from liquid to gas with fluctuations in temperature and pressure. 

A compressor in the outdoor unit increases the pressure of the gaseous refrigerant and converts it into liquid refrigerant at low temperatures.

The cold liquid refrigerant then passes to the evaporator, where due to high temperature and low pressure, it changes back into gaseous form. 

When air sucked by the indoor unit is filtered and passes over the cold evaporator, its temperature is also lowered, and then it is thrown back into the room. 

That cycle goes on and this is how the split system air conditioning unit works.

Multi Split System Air Conditioner

When thinking about buying a split system air conditioner, you may have come across two options. One is the single split system air conditioner, and the other one is the multi split system air conditioner. 

Usually in a single system, there is one indoor unit and one outdoor unit, but in case of multi system, there is only one outdoor unit with multiple indoor units. 

So if you want to cool down three rooms at a time or want to place three units in one place with one outdoor unit, you should choose a multi split system air conditioner.

Pros of Split System Air Conditioner

Unlike window air conditioners, where the compressor and all components are inside creating much noise, one big advantage of a split air conditioner is that it creates less noise. 

This is because noise is generated by the compressor, which is placed in the outdoor unit outside the room wall in these air conditioners.

Split air conditioners and window air conditioners are both cost effective compared to central air conditioning systems. So, if you use one to two rooms regularly and want to save money, you should choose one of them.

Split air conditioning systems are way easier to install than central air conditioning systems, because they do not require ducts to be placed all over the house. 

You just have to install the outdoor and indoor units. Also, if you want to cool down 2 or 3 rooms, only one outdoor unit can be used to control 2 or 3 indoor units.

Split air conditioners are more energy efficient than central air conditioning system, as energy is lost when passing through the ducts of these systems. Also, if the ducts are damaged, further energy could be lost. The energy efficiency of ductless air conditioner systems is double that of standard air conditioners i.e. above 30 SEER.

Cons of Split System Air Conditioner

Air conditioners have air filters placed in them which filter air from dust particles before it enters the air conditioner. These filters need to be cleaned regularly say every six months. 

Otherwise, they can be clogged with dust which affects the air conditioner efficiency and cooling. It can also cause the air conditioner to work harder and utilize more electricity.

Another problem you may come across with a split air conditioning unit is the low levels of refrigerant. Refrigerant passing in the copper coils is responsible for cooling the evaporator. 

When it comes in contact with the evaporator, air is cooled then thrown back into the room. That’s how refrigerant is responsible for cooling. If the refrigerant level drops or there is gas leakage, the cooling capacity of air conditioner is affected.

When compared with window air conditioners, split system air conditioners are more expensive. 

So if you need to save money or live in rented property, it might not be the best choice to purchase a split system air conditioner. Plus, you will also have to additional costs on service yearly or every six months.

Unlike window air conditioners, both indoor and outdoor split system air conditioning units are fixed on the wall. 

So if you live in a rented space or want to be able to change the air conditioner location, you should go for a window air conditioner not a split system.

How to Install a Split System Air Conditioning Unit?

After buying a split system air conditioner, the first thing to do is to install it. 

As the installation is tricky, it requires technicians. Some main points to consider prior to installation are:

How to Clean Split System Air Conditioner?

Cleaning the split system air conditioner is a big task compared to a window air conditioner. When running an AC for many months, its service must be done every 6 months or yearly. 

Otherwise, the AC cooling capacity and energy efficiency could be affected. 

Also the air filters can get clogged with dust particles and microbes, which affects the air quality and causes the AC to work harder thereby consuming more electrical energy. 

Moisture trapped in the air filters can lead to fungus or mold formation. Following are a few important steps for cleaning the air conditioner:

How Much Does Split System Air Conditioners Cost?

In every country, the price range for split system air conditioners varies. But in Australia, costs to buy split system air conditioner range from $600-$5400 depending on the brand, company, model, size, upgraded features and cooling capacity you choose. 

Apart from that, you have to pay the installation costs too which are in between $60-$110 per hour. 

But there are obviously other factors which contribute to the total amount you pay like the size of the unit, its type and how much cable, wires and ducts are needed for installation.

What Size of Split System Air Conditioner Should You Choose?

One big issue while buying a split system air conditioner is determining what size you should opt for.

This depends on the size of your room and a number of other factors. The bigger the room, the higher the cooling capacity you need. 

There is some estimation of room size and AC capacity needed, where if your room is small with 20 sq m or less of area, you should buy AC unit with 2-2.5kW of cooling capacity. 

If the room size varies from 20-40 sq m, you would need 2.5-5kW capacity. 

With 40-60 sq m, it changes to 4-6kW capacity and if the room size is more than 60 sq m, you should go for the one with range of 5-9kW.

Other factors which can affect the cooling capacity are the location of room; if it is near kitchen or somewhere with heat interference, insulation of the walls, windows and climate of your region.

If you are living in a hot region, you would need to buy an AC with higher cooling capacity, whereas you would need one with lower cooling capacity for colder regions.

Looking to buy a window air conditioner?

Summertime is nearly here and you would obviously like to spend your time at home in a calm and cool environment. 

If you don’t have such luxury yet, you are probably thinking about buying an air conditioner

For people living in a one-room apartment or looking to save on electric bills, buying a window air conditioner might be the best decision to make your room comfortable enough for better quality sleep.

Why do we use a window air conditioner?

A window air conditioner is one of the simplest forms of air conditioners in which all the components are fitted inside one single unit. 

window air conditioner

This type of air conditioner is specifically designed for a single room and is mounted in the window, half inside and half outside.

A window AC cools down the room temperature. The operation of this AC is the same as other air conditioners except it has everything in one unit. 

Like other air conditioners, it takes the hot air from inside, and, after filtration, passes it over the evaporator coils and the refrigerant coils so heat and humidity are removed, and the cold air is blown back into the room. 

The refrigerant’s temperature is raised by the compressor and the heat is expelled out. 

After the condensation process, the refrigerant is again cooled down before it is ready to take another cycle. 

If you are living alone or with a few people only, you can cool down one room with a window air conditioner instead of having an expensive central air conditioning system, and this can also save you money.

Window air conditioners: What are the benefits?

Easy to install

One big advantage of buying a window air conditioner is that you can easily install it even by yourself. 

In contrast to the heavy central air conditioning system, a window AC is lightweight, and you can shift it from one room to another by yourself. 

window air conditioner

Also, if you are living in a rented apartment and do not have a central air conditioning system, your first choice should be buying a window air conditioner that you can carry with you whenever you have to move.

Save you from high electric bills

When you are not using all the rooms in your home at the same time but tired of paying high electric bills, installing a window air conditioner could be the best option for you. 

These air conditioners are known for having more energy efficiency. According to the U.S Environmental Protection Agency, they are designed as energy-efficient and cost less money.

Since it just works on cooling a single room instead of the whole house, it needs less time and energy for cooling. 

Obviously, this leads to less energy and electricity bills.

Extremely low cost

One major advantage is the lower cost of the window air conditioner than other types of air conditioners. 

People who have low income usually think that they can’t enjoy the luxuries of life. 

For those people, a window air conditioner has been developed with extremely low costs.

window air conditioner cost data

The price range can vary due to different brands’ availability. You can purchase a Window AC for as low as $200 and as higher as $3000 which still is reasonable compared to central air conditioning systems.

No high maintenance costs

If you have a central air conditioning system or know someone who does, you might be familiar with how much money is spent on its maintenance. 

A really complex air conditioning unit means maintenance is complex too and requires experts.

But with a window air conditioner, you don’t have to set aside a portion of your income for maintenance. Just like its design, its maintenance is also quite simple. 

And you would be surprised to know that you can do it all by yourself.

Window air conditioner: The drawbacks


A window air conditioner can be very noisy compared to a central air conditioning system and split air conditioner. 

If you need a peaceful environment and cannot sleep in noise, you probably would not want to install one. 

It’s not used in offices, where a quiet and calm environment is needed for people to focus on their tasks.

Security risk

Of course, after buying expensive equipment you would want to keep it safe. One disadvantage of a window air conditioner is its security risk. 

Obviously, it’s designed in a way that it is half inside and half outside of the window, and several security measures are also available. 

But still, if you will be away from your home for a long time, you will need to place it inside for more safety, and people usually find that really exhausting.

Losing the comfort of window

Another drawback of installing a window air conditioner is losing your space for the window. As the name suggests, it is installed on the window and utilizes the entire space. 

window air conditioner

If you want fresh air or need to open your window, you cannot, and this sometimes becomes a frustrating situation. However, you can remove the Window AC if you want to be able to open your window for a few months.

Designed for rooms only

Due to hot weather, you might want to be able to spend your time in a cool environment but are short of money. 

If you think that buying a window air conditioner can help you cool down the entire house, you are wrong! 

You can buy it only to cool down a single room, because it is specifically designed with a cooling capacity that can only cool down a small space.

Window air conditioner: 5 things to know before you buy

Size of room and your AC unit

First things first, the room where you want to install your window air conditioner should match your AC. 

When you go to buy an AC, the first thing the salesperson will ask you about is the size of the room. That is because the cooling that your window AC provides depends on its capacity and your room space. 

Therefore, you need to buy an air conditioner that matches your room size. 

Buying a window air conditioner that is too small relative to your room space will lower its cooling capacity, and it wouldn’t be able to cool down the room as expected. 

Also, its compressor would need to work harder to cool down the room leading to high energy and electricity bills.

Similarly, if the size of your window AC is large, relative to your room, its cooling capacity would be higher. 

It would create an uncomfortable environment where you cannot get a good night’s sleep. Apart from that, a larger AC means its cooling cycles will be short and it will exert pressure on the compressor.

Energy efficiency

With innovation and advancements in every field, electronic technology is also making progress. Machines and other electric equipment are becoming more energy efficient. 

For air conditioners, they are becoming more energy efficient using less electricity and power but performing the same work.

The Bureau of Energy Efficiency has standardized the energy efficiency ratings. 

The higher the rating, the less energy and electricity used by the air conditioner. Refine your choice and choose the more energy-efficient window air conditioner. 

The most efficient AC is the one with 5-star ratings. 

It can cost you more initially, but can save you money in the long term. Your second option can be the air conditioner with 3-star ratings. 

Energy efficiency is measured in the energy efficiency ratio showing the BTUs that the air conditioner uses for every watt. 

The more the BTU units, the more the air conditioner is efficient. 

Cooling capacity

One big requirement before buying a window air conditioner for your room is evaluating its cooling capacity.

You should buy the air conditioner with the maximum cooling capacity according to your room size. Cooling capacity is measured in British Thermal Units (BTU).

The more the BTUs, the higher the cooling capacity. It’s essential to buy an air conditioner which matches your room space closely. 

cooling capacity

High cooling capacity air conditioners within a small room can affect the humidity of the room. Besides, they can generate higher electricity bills. 

The same effects occur with a very low capacity window air conditioner. 

To evaluate the exact cooling capacity you need, you have to calculate the area of the room in square feet and tally it with the above chart. 

Variation in BTU can be necessary if some other factors can affect the cooling like direct exposure to sunlight or the number of people in the room and other heat-generating factors.

Proper installation

After you have evaluated the room size, the cooling capacity of the window air conditioner needed for your room, and the energy efficiency, the next step is to know everything about the installation. 

The installation process is not as complex as for central air conditioning systems and does not require expert technicians, but there are still some things that you need to know ahead.

window air conditioner installer

First, you have to measure the size of your window and the size of AC that you’re going to install. The measurements don’t have to be exact and perfect, since if there is a little space left in between, it can be covered with different methods. Also, if you are thinking of installing it on the wall, you must take the exact measurements. 

Second, it’s better if you spend some money to have an expert technician install it.

Voltage requirement

Voltage is one of the major requirements as it is needed for your air conditioner to operate. You have to make sure that the voltage you get in your home is enough to support your AC. 

Many of the other electric appliances work on voltages lower than 220 V. 

The air conditioners with low cooling capacity i.e. lower than 15000 BTUs can run on 115-125 V. However, the ones with high cooling capacity run on 220 V. 

So, whatever the cooling capacity of your AC unit is, make sure it matches the voltage in your home.

Window air conditioner: Wrapping Up

If you cannot afford a central air conditioning system or split unit AC, or if you’re a living on rent in one room, a window air conditioner could be the best choice for you. 

However, buying without having complete knowledge can lead to to long-term problems and financial loss. 

So, you can use the above-mentioned tips to help you narrow down your choices and pick the most suitable option for yourself. 

Summer preparations are incomplete without having an adequate space cooling arrangement. It is never easy to bear the scorching sun and blazing hot winds for days. 

To be ready for hot summer seasons, there is a wide range of space cooling products available in the market today.

In fact, among cooling appliances, portable ACs have become increasingly popular recently. 

New and advanced varieties are frequently available in the market, so it can often be a difficult task for you to buy one for yourself.

Going through this article before buying a portable AC can help you select and purchase the right product.

What is a portable air conditioner?

portable air conditioner

A portable AC unit is a compact portable system used for space cooling purposes. 

These units are an alternative to split-type and window-type air conditioners, where they stand on the floor and are easy to install. 

They usually have wheels so they can easily be moved from room to room as per the requirements.

Why should you go for portable ACs?

Air conditioners are an indispensable part of every household, commercial and corporate space during the unbearable summer season. 

However, it might not feasible to install split-type or window-type air conditioning units, because of space and financial constraints.

In such a scenario, portable appliances become handy to fulfill space cooling requirements within available resources. 

Like portable fans and air coolers, portable ACs are a great option for ensuring efficient space cooling.

Here, we will look at some advantages and disadvantages of these systems that are useful to know before you make a purchase.

Advantages of a portable air conditioner

1. Easy to install

Portable ACs are easy to install as they don’t require technicians and professionals for installation. 

With their easy to install feature, you can simply unpack the appliance, install the window vent kit and start using your product.

This is a great advantage over split-type and window-type air conditioners, which require complicated installation, drilling, and adequate space allocation. 

They provide ease of installation for quick and easy usage.

2. Convenient portability

The portability of these ACs makes them very convenient and contributes to their popularity. They are usually compact and lightweight electric appliances weighing around 50-60 pounds. 

convenient portable air conditioner

You can easily transport or carry them from one place to another.

Most of the portable ones have got wheels installed on their bottoms. This way, you can easily move them around, as per your space requirements, without having to drag or carry them. 

3. Diversity of operation

Portable ACs can be operated in multiple modes as per the user’s requirements. 

Many advanced air conditioners come with heating mode to fulfil your winter requirements too.

Besides cooling and heating, the dehumidification feature helps you dehumidify the environment, especially during rainy seasons. 

You can also operate them on fan-only mode to enjoy adequate space cooling in moderate weather.

4. Smart controllability

Portable ACs come with smart controllability features for easy operations and user control.

Disadvantages of a portable air conditioner

1. Noise

One of the disadvantages is that most of them are somewhat noisy. 

Most electrical appliances are noisy, so portable ACs might not fit a space that requires extreme quiet.

However, unusual noise and sounds from your portable unit may also indicate a problem or need for maintenance. 

Do consult an air conditioning professional if you witness unusual noise from the product that sounds different than its regular operating noise.

2. Less economical

Portable ACs often tend to be less economical than conventional split type and window air conditioners. 

This is because they don’t use any outdoor unit so they produce some warm air too and need to be used for more time to reach optimum cooling.

Particularly in extremely hot weather, this might make you keep your air conditioner switched ON for a longer period of time to ensure effective space cooling

Hence, they may often turn out to be less economical relative to conventional air conditioners.

3. Unfit for open large spaces

Another disadvantage of portable ACs is that most of them do not fit well in open large spaces. 

They are only a good option for compact small rooms and spaces.

In the case of larger spaces and bigger halls, they are not an effective option for adequate space cooling. 

However, multiple air conditioners can be installed in such places, where necessary, to achieve optimal space cooling, but that can be expensive.

5 things to consider when buying a portable air conditioner

With many product varieties available in the market, it can get difficult to choose one for yourself. 

While different products offer different features, you must carefully analyze various products to buy the most suitable one for you.

Here we will highlight 5 things you must consider when buying a portable air conditioner.

1. Size and cooling capacity

2. Product cost

While making any purchase, costs and finances are the main factor to consider. 

The same applies to portable Acs, where a variety of options are available in the market with varying price ranges.

The price typically varies from $250 to up to $500 or even more, depending on various factors including brand, product material, warranty, and additional features of smart controls and multiple operational modes.

portable air cooler Vs air conditioner

Before buying a portable AC, consider your budget and finances to choose the right product. 

Compare various products, their features, and price tags to select the most suitable product from the wide variety of available options.

3. Draining and maintenance

Even though portable ACs don’t require complicated installation and maintenance, you must regularly drain moisture. 

During the cooling process, the air conditioner pulls moisture out of the air and collects it in a pan that you drain regularly.

You can drain this moisture in various ways. You can manually remove the pan and empty it when needed. Otherwise, you can incorporate gravity draining to drain the moisture to a different location or use a pump for regular water drainage.

Many people may consider buying advanced portable AC units that come with self-evaporative technology. 

This way you don’t have to worry about recurrent manual drainage of moisture. Besides that, you also need to clean filters and defrost the unit as part of maintenance.

4. Ventilation modes

Portable ACs ensure space cooling by venting out hot air. Products come with a window venting kit which is usually simple and easy to install to vent out hot air. 

For this reason, they are supposed to be kept close to a window.

When purchasing a portable AC, consider the space where you intend to install your product.

Accordingly, consider whether the size of the venting kit will be enough or not. If your place of installation is far from a room window, then look for products with longer vent kits.

Portable ACs either have single hose ventilation or dual hose ventilation. This is an important factor to consider when buying one for you. 

Usually, dual venting hose air conditioners are more energy-efficient than those with a single hose because they utilize separate hoses for air intake and exhaust.

5. Smart functionality and multiple modes

Portable AC units come in a wide variety that offers various features. 

You must consider your requirements and additional product features to choose the best product within your budget range.

3 Mistakes to Avoid When Buying a Portable Air Conditioner

As we noted earlier, you can find all kinds of air conditioners in the market. That includes portable air conditioners, classified further into different types. 

Therefore, some buyers make mistakes when buying the machines due to the confusion resulting from the numerous types available.

However, we are here to clear the confusion. Always remember to avoid the following three mistakes if you want to buy a perfect portable conditioner regardless of the type or brand.

1. Ignoring Venting Requirements

Remember, venting is good because it removes moisture from the air. Suppose you don’t do proper venting. In that case, the moisture will continue to build up and neutralize the cooling effects of the air conditioner.

Furthermore, if the AC unit is not vented correctly, the hot air will remain locked inside the space making the room hotter. 

Therefore, it is essential to consider the venting requirements in order to maintain an efficient air conditioner.

2. Failing to Consider Your Room Size

Knowing the size of your room helps to determine the right BTU for your space. 

For instance, if one uses a portable AC with a high BTU rating in a small room, the results will be unsatisfactory. In addition, such a mistake can result in a decrease in the air conditioner’s lifespan.

On the other hand, if the room is too big for the BTU rating, it overworks the machine. 

Consequently, the device fails to meet the effective cooling needs, thus causing the room to remain hot. In addition, that also increases energy consumption leading to higher energy bills.

3. Failing to Consider the Energy Efficiency Ratio

The energy efficiency ratio is the measure of how effectively an air conditioner will operate at certain prevailing room temperatures. 

Generally, the rato is calculated by dividing  the AC air capacity by its power.

A higher energy efficiency ratio means an air conditioner will provide a cooling effect for every watt of the energy supplied. 

So, if you fail to consider such a ratio, the machine will not meet your cooling requirements optimally. 

Furthermore, you will incur high energy bills since the cooling system will be consuming too much energy and not giving proper cooling results.

Single-Hose Portable Air Conditioner vs Dual Hose Portable Air Conditioner

Portable air conditioners are also grouped depending on the type of venting: the Single hose and dual hose portable air conditioners. 

The two have the same working principles; however, each has its disadvantages and disadvantages.

Generally, it depends on the size of the room you want to cool and your preferences when choosing between the single and dual hose portable air conditioner. 

First, the Single-hose portable air conditioners are ideal for small rooms. If you intend to cool a larger space, you need to use the Dual hose portable air conditioner. 

Moreover, the dual hose one has a more efficient and quick air exchanger compared to the latter. 

On the other hand, the single hose versions are more affordable than the dual hose portable air conditioner. 

Further, the dual hose versions tend to be noisy, but that depends on the model you are buying. 

In summary, you can easily choose a suitable cooling system, whether single or dual hose portable air conditioners depending on room size, budget, and personal preferences.

Window vs. Portable – Which Should You Buy?

As we stated earlier, there are various types of cooling systems. While portable air conditioners are most preferable, windows air conditioners also compete with them. 

The two are the most popular options in the market, but which one should you buy?

The Window air conditioner is a small appliance that fits into an open window for cooling. On the other hand, the portable air conditioner is a self-contained portable system for cooling a single room. 

The window air conditioner doesn’t take floor space; therefore it’s suitable for those living in small rooms. 

So depending on the room size and preference, you can choose wisely between the two.

Further, Window air conditioners are heavy to lift, which makes them challenging to install, while portable air conditioners are the perfect bet if you desire an easy-to-install cooling system. 

Wrapping up

Portable ACs are a valuable product for all kinds of usage. A wide range of portable ACs is available in the market varying in their features and price range. 

They come with their own advantages and disadvantages as well. 

You should consider various essential factors in order to buy a portable air conditioner that meets your requirements.

I hope this guide will help you in selecting and buying the best portable AC for yourself, keeping all the factors that we discussed in mind.
