Best Portable Air Conditioner – Comparisons and Reviews

If your air conditioning system does not work, or it isn’t built into every room in your home, using a portable air conditioner could be the best way to cool your space.

Allowing you to cool the air in the room you place it, a portable air conditioner could be the ideal product when you need to cool the air in a hot room, or even in an RV.

Quick Look

What’s the difference between portable and regular air conditioners?

Portable air conditioners can be moved from room to room, and even house to house. They are not fixed to a wall, and they can usually be moved relatively easily.

You may be pleased to know that portable air conditioners don’t tend to have any parts that can be seen outside your window, which means you won’t have to worry about what the exterior of your home will look like.

The ease of installation is typically one of the main reasons why many people like to buy a portable air conditioner. Within a few moments, you could have the unit up and running so that the room is a lot cooler in a very short span of time.

If you tend to spend part of your summer in one home, and the rest of the summer in another, you can take your air conditioner with you, should you wish. This means you may not have to buy more than one portable air conditioner, thereby saving yourself a little bit of money.

How do portable air conditioners differentiate?

Portable air conditioners tend to differ in the size of the room that they can work in. Some air conditioners are ideal for use in rooms of more than 300 square feet, but others are only suitable for rooms that measure 170 square feet.

If you are looking to condition a particularly large room, you will need to look for a unit that has the capacity to cool that room. If you use a less powerful unit in a large room, you will not get as much benefit from it.

Things to look for

When shopping for a portable air conditioner, it would be wise to buy one that is not too heavy to carry or wheel between rooms. If you’re planning on purchasing a unit online, check to see how much the unit weighs. If there are no details available, ask the buyer for more information.

Alternatively, you may want to visit an “Offline” store and see which ones you can pick up or move with relative ease. Don’t forget that electrical goods are usually cheaper to buy online than they are in a regular store, so make a note of the brand and model number, and look for it online.

Some portable air conditioners can be a little noisy, which means they have the potential to be quite distracting. If you’re in the market for a new air conditioner, try to find one that has a reputation for being quite quiet.

The quietness of the unit may not be your primary concern, but if you do end up buying one that is a little noisy, you may regret your purchase. Read customer feedback that you come across so that you can identify the quieter models.

How to make the most out of your new portable air conditioner

Portable air conditioners are typically less expensive than air conditioning systems, but that does not mean you shouldn’t try to make the most of them. A good way to get your money’s worth is to make sure you only buy a unit that is suitable for the room you’re putting it in.

In other words, if your unit has been made to cool a room that is 250 square feet, you should not place it in a larger room. Use an air conditioning system that has enough power to cool your larger rooms, so that you not only get your money’s worth, but so that the room is a lot more comfortable to be in.

Do I really need a remote control?

Some portable air conditioners come with a remote control, and as handy as this feature is, you may not always need it. If you’re placing the unit in a relatively small room, there may be no need to have a remote control.

Remote controls typically allow you to change the speed of the fan, switch the unit on or off, and place it on “Sleep mode.” Some remote controls come with additional features too, allowing you to set a timer, or adjust the temperature.

While not every portable air conditioner has a remote control, they can be useful if you do not want to get up to adjust the settings. While this feature can be quite convenient, it is often just as easy to adjust the unit via the controls on the air conditioner itself.

Prerequisites to using a portable air conditioner

If you are planning to buy a portable air conditioner, you need to make sure that you have enough space for it. Air conditioners are available in many different shapes and sizes; however, no matter the size of the room you plan to place the unit in, you need to make sure you have plenty of space for it.

Work out where you are going to place your air conditioner, and measure how much space you have. The smallest air conditioner is approximately 13 inches wide, 12 inches deep, and 27 inches tall, and you will need to leave at least 2 inches on every side for the unit to draw air in. This means you will need to have at least 15 inches (width) 14 inches (depth) and 29 inches (height) to spare.
