Currently, the cooling market is packed with a wide variety of options to choose from when you absolutely need to make your living or workspace comfortable.

The benefit of choosing a portable air conditioner is first and foremost the convenience of easy (or no) installation, the ability to move from space to space throughout the day, and finally not having to conform when you don’t have traditional cookie-cutter windows.

Things to consider when shopping for the best portable air conditioner
Finding the best portable air conditioner for your space requires consideration of where and how you will use the unit. Most importantly you need to calculate the square footage of the space you need to cool, because that will inform the amount of BTU or cooling power you will need the unit to have. With a wide variety of brands and models to choose from you can find straight forward, simple, easy-to-use designs, as well as more high-tech models equipped with the latest smart technology and extra features. The best portable air conditioners, should cool your space quickly, have easy venting systems, be simple to move around and they should operate at a comfortable noise level.
How large of a space do you need to cool?
The power of any air conditioner is measured in BTU (British thermal units), which refers to the amount of energy required to raise one pound of water one degree Fahrenheit. While it might be tempting to purchase a lower BTU machine because they are often less expensive, you should check the square footage of your room first. Higher BTU machines can cool larger spaces than smaller ones.
The downsides to buying a low-BTU unit for a large room are clear, but getting one that’s too powerful for your small space isn’t smart either. While you might assume that a more powerful machine would have to work less to cool your room, the fact that the machine would quickly cool and then cycle off (to maintain your desired temperature) can actually end up taxing and overworking the compressor. This overworked compressor can then shorten the lifespan of the air conditioner.
An extra tip to note is that in addition to the exact square footage measurements, you have to consider whether the room has extra sun exposure. For example, a room that faces west, would have an excess of sun during the summer and experts suggest adding 10% onto your overall room size to accommodate that extra heat.

How quiet or noisy is the unit?
If you’ve ever woken up at night to the rumbling and crackling of a noisy air conditioner then you know how important it is to consider operational noise. Some people are sensitive sleepers and will easily awake when their air conditioner cycles between on and off as the compressor adjusts to maintain the room temperature setting. Noise level is measured in decibels, which is a unit for expressing the relative intensity of sounds on a scale from zero (least perceptible) to about 130 (pain-inducing). The hum of the average refrigerator is about 50 decibels, and a whispered conversation is about 20 decibels. If you are to be using the air purifier in an office or living room where conversations are occurring, a louder setting may not be disruptive at all and may generally go unnoticed. The best portable air conditioners will have only a moderate level of noise, ideally between 40 to 55 decibels.

Choosing an appliance that sticks with key main features and that uses menus and controls that are so straight forward that you don’t need to read a thick manual or PDF can make your user experience pleasant.

FAQ: Other questions people have about portable air conditioners
What is required to set up a portable air conditioner?
While it’s important to review the specific instructions of the model air conditioner you are considering purchasing, portable air conditioners typically have a quick and easy setup. The air conditioner sits on wheels so can be easily moved into place. In order to remove the warm air and moisture, you will need to vent to an outside location. Window kits include an exhaust hose, and are designed to fit into a wide variety of sizes and types of windows. Some models can vent into a drop ceiling or through a wall, but you need to check the model to see if that is possible.
What size air conditioner (BTU level) should I get?
You need to calculate the size of the room or space and determine the area in square feet that you will be cooling in order to select the correct model. Portable air conditioners should list the number of square feet they can cool right in the product description or on the packaging. Smaller units between 7,000 and 10,000 BTU can typically cool up to 300 square feet. Larger spaces that are between 350 and 700 square feet need approximately 11,000 to 15,000 BTUs of cooling power.
Are portable air conditioners energy efficient?
The best way to check the energy efficiency of the portable air conditioner that you are considering is to look at the Energy Efficiency Rating (EER). In general portable air conditioners are slightly less efficient than wall-mounted units, but more efficient than running a full central air conditioning system.
How noisy are portable air conditioners?
If you are concerned about the noise created by the portable air conditioner, look at the decibel rating (dB level) on the product description page or product packaging. Most portable air conditioners operate between 48 dB and 60 dB. If you’re noise-sensitive we recommend sticking with a machine under 55 dB. With any unit, noise levels will increase as the unit is switched from low to high cool settings.
