What is a portable air conditioner exactly?

A portable air conditioner is a device designed to keep your home fresh, and it requires little installation. It features one or two tubes that are placed in the window to suck in and expel air from the outside. This system is generally sealed to increase performance, and many models include everything you need for this. Otherwise, you will have to buy the parts separately.

What installation do these devices require?

Your portable air conditioner will always need an outlet to the outside. This is why its pipes must be placed in a window, or in some cases a door. You should ideally seal that window, or hot air will re-enter your home. Unlike other systems, portable air conditioners are simple to set up, and you can easily do it yourself.

How many hoses can a portable air conditioner have?

Portable air conditioners will feature either one or two hoses to the outside. Single-hose devices are capable of absorbing hot air through a grille, which is then cooled inside using a compressor and returned to the room. Once the cooling process has taken place, the hot air is blown out of the house through a pipe.

Double-hose units absorb the air from the outside through one of the pipes. The device cools it inside and propels it into the room. The other tube is used to expel the hot air generated by the compressor. Since you have an inlet and an outlet pipe, the hot air never returns to your home.

Are portable or fixed air conditioners better?

The latter will generally consist of two units. Located outside your home, the first one integrates a compressor to cool the air. The other one is placed indoor and is responsible for distributing the cold air in the room. While these models are less noisy, they require professional installation and are more expensive.

Portable air conditioners come with the compressor inside and cool the air they suck in from the room or outdoor. They then distribute it and expel hot air towards the outside. Portable models require almost no installation and are more affordable, but also noisier, less efficient, and less aesthetic. You can compare the two types in the table below:

Feature Fixed Portable
Set installation
Ease of installation
Noise level

Are portable air conditioners and air handlers the same?

You may be wondering whether it is possible to buy a portable air conditioner without a hose or not. In reality – and this may surprise you, such models don’t exist on the market. What you will find are so-called air handlers, devices that work like a fan and expel air and cold water.

The problem with them is that they cannot remove hot air from the room, so they don’t actually manage to cool it. You will only have a refreshing feeling when you stand directly in front of it. This is why we recommend that you opt for a portable air conditioner. While this device is more expensive, it is also more efficient.

Where should I place my portable air conditioner?

You should always have this device near an outside air outlet. Windows are most often used, but it can also be a door with access to a terrace, balcony, garden, or patio. Your portable air conditioner should be at least 20 inches away from any wall or furniture.

Ideally, your window should be closed or sealed so that no heat can enter from outdoor. The majority of devices come with the material needed to seal the window temporarily for setup. Make sure that you are comfortable with the installation before purchasing your portable air conditioner.

Is the upkeep of a portable air conditioner difficult?

A portable air conditioner requires very basic maintenance. If it includes a water tank for condensation, you should empty it every time it is full and make sure it is always clean. Follow the manufacturer’s instructions regarding the cleaning of the filters. Last but not least, don’t forget to remove dust from the fan blades with a damp cloth.

How big should the hoses be?

This is a hard question to answer, as it will depend on various factors. The hose should be long enough to go from the portable air conditioner to the window. Don’t forget that these devices always have a hose to expel the hot air. If the one that comes with your device doesn’t fit your needs, you can easily buy another compatible one.

“The first step to finding the right kind of cooling unit for your home is to assess your own needs. For example, a large 4-bedroom house will clearly have different cooling requirements than a small studio apartment. This is where cooling capacity comes into play. Capacity is measured in BTUs or British Thermal Units.”

What should your portable air conditioner have?

While most air conditioners will feature the same essential functions, it’s always good to know what to look for. These are some things that you can expect to find in virtually every model and that will make it easier for you to use. In the following list, you can learn more about these features:

  • Timer. To program it.
  • Various speeds. At least three: low, medium, and high.
  • Night function. This reduces the noise of the device at night.
  • Wheels. Four wheels are ideal to facilitate transport and prevent the device from falling over.
  • LED screen. This makes the configuration much more comfortable.
  • Remote control. You can control the air conditioner from a distance.
  • Washable filters. They are more affordable in the long run.
  • Installation kit. While you can always buy it separately, it is better if it is provided by the same manufacturer.

What are the advantages of portable air conditioners?

There is no doubt that a portable air conditioner is a handy device on hot summer days. You should already have a good idea of what you expect from this device, but there are still various key criteria that you need to evaluate before making your purchase. We will analyze them in a minute, but let’s look at the main benefits and drawbacks of portable air conditioners first:

  • Their installation is fairly simple
  • They cool efficiently
  • You can take them from one room to another
  • Some models can be fairly noisy
  • It isn”t as comfortable as having air conditioning throughout the house

Shopping Criteria

Trying to sleep at night when it is really hot can be impossible, which is why having a portable air conditioner in your home is an excellent option. Now that we have clarified the most common doubts regarding these devices, let’s have a look at the main criteria to evaluate before making your final decision. You will soon be ready to wave the heat goodbye!

Heat Pump

Most portable air conditioners are only designed to cool the air. However, you can also find some models that feature a heat pump. As you can imagine, this option tends to be less affordable, so make sure you consider your real needs before choosing one or the other. They are very helpful, for instance, if your home doesn’t have a heating system.

Cooling Capacity

The cooling power is usually calculated in frigories per hour (fg/h). This is good to keep this in mind, as it will help you evaluate the type of appliance you need. The size of the room (in square feet) is one of the most critical factors in determining the cooling capacity of your portable air conditioner.

If the device has fewer frigories than you need, it won’t be of much help. If the opposite happens and it has too many frigories, your room will be too cold, and you will waste energy. in the following table, you will also find the cooling power you need expressed in another common unit of measurement: the British Thermal Unit (BTU).

Room size (in sq ft) Frigories per hour needed BTU/h
Less than 160 1,000 4,000
From 160 to 215 1,500 6,000
From 215 to 320 2,000 8,000
 From 320 to 430 Between 2,500 and 3,000 Between 10,000 and 12,000


The noise level of portable air conditioners has long been considered a problem. However, this issue has improved dramatically in recent years. Most models are below 70 decibels, which is the equivalent of normal traffic. If you really want a device that you won’t notice, go for a portable air condition that emits less than 50 decibels.

Some portable air conditioners will need to be drained and integrate a container to collect the water that evaporates. If you do not maintain your appliance correctly, this accumulation of water can cause the appearance of mold. To avoid this, we recommend that you purchase a self-evaporating device that returns humidity to the room.

Energy Consumption

If the cooling power is measured in frigories per hour, the electricity consumption is calculated in watts or kilowatts (kW) per hour. While the units of measurement are different, they are related. You can convert frigories into watts by multiplying them by 0.86; divide this result by 1,000 to obtain the value in kW.

Remember that how much you pay on your electricity bill will depend on the price per kilowatt-hour (kWh). The more kilowatts the device consumes, the more expensive your portable air conditioner will be in the long run. The table below will give you an idea of what to expect:

Room size (in sq ft) Frigories per hour needed Watts per hour/Kw per hour
Less than 160 1,000 860/0.86
From 160 to 215 1,500 1,290/1.29
From 215 to 320 2,000 1,720/1.72
From 320 to 430 Between 2,500 and 3,000 Between 2,150 and 2,580/2.15 and 2.58


A portable air conditioner is ideal if you don’t want to go through the hassle of installing a fixed device in your home, or if it’s simply out of your budget. It is also useful if you rent or have a beach house. It will allow you to stay cool with minimal installation and fairly economic investment. Double-hose units are the most efficient.

Throughout our article, you have learned when and why a portable air conditioner can be more suitable than a fixed device. You also know where to place it, its cooling capacity, or its energy consumption. You’re all set to use and maintain your new appliance, and that means you won’t suffer from the heat anymore.
