What are Portable Air Conditioners?

Portable air conditioners are small electric devices that remove excess heat from rooms or entire houses. A typical portable air conditioner has a network of tubes and a special type of fluid called refrigerant. These devices also have exhaust kits that comprise long pipes that pass through any of the windows of your house.

The primary purpose of using portable air conditioners is to cool a room. These devices are ideal if you do not have a central AC system in your home or office.

Also, you may consider using a portable air conditioner in areas that require additional cooling. The refrigerant absorbs heat from the air in the room when the portable air conditioner is working. The excess heat is then channeled across the hose through the window to the outside of the room.

Modern portable air conditioners have many features to enhance their usefulness. Notably, some common brands have a dehumidifier that removes excess moisture that may accumulate in a room.

Thus, using a portable air conditioner with a dehumidifier helps cool the room and maintain the air quality indoors. Other standard features of portable air conditioners include programmable timers, multiple speeds, and remote controls. All these features let you adjust the air conditioner’s performance to your needs at any given time.

When to Use a Portable Air Conditioner

You will often be at a loss to decide whether you need to use a portable air conditioner. Here are situations that make it necessary to acquire and use a portable air conditioner.

  1. When you need supplementary or spot cooling. Portable air conditioners provide additional cooling in large houses where the central air conditioning system’s effect is not sufficient. Alternately, you may use a portable air conditioner in large spaces to cool areas that notoriously remain hot, inclusive of kitchens.
  2. You need to keep your windows open. Unlike window units, portable air conditioners will not block your windows. It will be an excellent idea to use portable air conditioners if you need to keep your house’s windows open for the sunshine or fresh air.
  3. The weather is often humid. Portable air conditioners have inbuilt dehumidifiers that help to keep the air indoors comfortable. If the air in your house or office often gets quite humid, consider using a portable air conditioner during the hot days to keep the temperatures down and maintain the air’s quality indoors.

Factors that Determine the Effectiveness of Portable Air Conditioners

Many would-be buyers of portable air conditioners often ask themselves whether these devices are worth it. Well, the answer to this question lies in how several seemingly unrelated factors determine the outcome of using your portable air conditioner.

Creating and maintain a cool environment in your house maybe even more expensive than getting additional heat. As we move towards the summer, expect to spend a lot of money keeping your indoor environment cool using either a central air conditioner or a portable one.

Here are some of the factors that determine how effective a portable air conditioner can be.

Weather Conditions

The hotter it is, the more expensive it will be to maintain the desired levels’ indoor temperature. There will be a considerable amount of hot air during scorching days that will have to be moved from the indoor environment to the outdoors.

Therefore, your portable air conditioner will work harder and for longer to keep the indoor environment cool enough for your comfort. You will have a small amount of hot air to be moved to the outside during less hot days.

Cost of Electric Power

The cost of electric power determines how effective your portable air conditioner will be. If the rates of electricity keep fluctuating, depending on the prevailing weather condition, it will be more useful to use an air conditioner when the rates are low than when they are high.

Using your portable air conditioner for long translates into increased costs of cooling the air in your house.

The Size of the Room

The room size that you would like to keep cool determines how effective it is to use a portable air conditioner. A rule of thumb is that you should always use an air conditioner with the matching capacity to cool your room.

Using a large air conditioner in a small room would be ineffective because the air conditioner’s excess capacity would be wasted.

Similarly, if you use a small air conditioner in a large room, you will pay a lot for electric power because the device will have to run endlessly, and yet it would not adequately cool the room.

Pros and Cons of Using a Portable Air Conditioner

When you must cool your room, you will have to choose from a range of options that includes a typical portable air conditioner, a window air conditioner, and the conventional central air conditioner.

Here are some of the benefits of using a portable air conditioner over the other options.

  • Ease of installation. Your portable air conditioner comes ready for use. You do not need to consider getting technical help to get it up and running. You must connect its exhaust kit through the window, plug it in, and you start experiencing a cool indoor environment.
  • Access to windows. Compared to a window air conditioner, a standard portable air conditioner does not deny access to your windows. This may be particularly important if you live in a small house and require lots of sunshine to keep the inside comfortable. Using a window unit in such a house will deny you access to the window.
  • Personalized performance. Most modern portable air conditioners have multiple settings for adjusting their speeds and other aspects of the operation. Some even come with remote controls that you can use to operate them conveniently. Thus, it is easier to operate a portable air conditioner than a conventional central air conditioning system.

It can be quite hectic and inappropriate to use a portable air conditioner to cool the temperatures in your home, office, or any other indoor environment during hot days.

The following are some of the cons of using a portable air conditioner.

  • They are less efficient than window units. Portable air conditioners consume more electricity and end up cooling less spaces than window units. It is because portable air conditioners release excess heat, which inadvertently increases the indoor temperature and the work needed to cool the room.
  • High noise levels. Some brands of portable air conditioners are quite loud. The noise may be high enough to interfere with the peace and tranquility in your house. Thus, it would help if you went for brands that have low noise levels.
