True to their name, portable air conditioning units are, well, portable—especially when compared to virtually all other types of equivalent cooling solutions. A portable AC unit sits entirely inside the home, transferring heat to the outdoors via an exhaust hose. 

While they take up floor space and don’t run quite as efficiently as their in-window counterparts, they’re your best bet (or only bet) in many scenarios. We have researched and tested a variety of portable air conditioning units in 80+ degree Fahrenheit weather with humidity levels between 70 and 80 percent to see which units performed best and kept our area cool and comfortable. 

We also reached out to Glenn Gault, the CEO at Gault Heating & Cooling, located in Northeast Ohio, to get his expert opinion. Continue reading for tips on how to choose the best portable AC unit for your space, and find out how the models we tested performed.

How We Tested the Best Portable Air Conditioners

After researching over 30 units, we chose the top portable air conditioners to test. Each unit was tested based on its British thermal units (BTUs) and recommended room size. (For a more detailed explanation of BTUs, read the Functions section after our product reviews.) For example, 10,000 BTUs and up were tested in a 550-square-foot living space. Units that offered less than 10,000 BTUs were tested in either a 250-square-foot room up to a 400-square-foot room.

When each room reached 80 degrees Fahrenheit, we turned on the unit and measured how long it took to cool the room to a comfortable 72 degrees Fahrenheit. We kept note of airflow, portability, and overall temperature of the air coming out of each unit. While testing, we also took note of the decibel level at each fan setting (high, medium, low). Once each particular room was cooled to 72 degrees Fahrenheit, we then left the unit on for 4 hours to test how efficiently each unit kept the room at that desired temperature.

After reviewing each unit and noting the above specifications, we then gave each unit an award it was best suited for based on our results.

Cons

  • Setting up the hoses can be inconvenient as they’re fairly cumbersome
  • Requires regular draining in heating mode and when humidity is above 70 percent
  • Battery runs down quickly when unit operates on high

Delivering 5,100 BTUs in cooling mode and 6,1000 when heating, the EcoFlow Wave 2 portable AC doesn’t need to be put away simply because the leaves are changing. Relatively lightweight at 32 pounds and measuring 20.4 inches long by 11.7 inches wide by 13.2 inches high, the battery-powered Wave 2 is a true go-anywhere appliance. 

We tested the Wave 2 in various settings, including at a hot baseball game under a pop-up tent, camping in an enclosed tent, a small office, and a hot nonvented warehouse. In each setting, the Wave 2 provided rapid cooling for up to 8 hours.

You can charge the unique EcoFlow Wave 2 via four methods: solar, AC, car charger, or a compatible power station (sold separately). While we didn’t have any solar panels on hand, we did charge with the AC adapter, car charger, and power station, all of which charged the unit effectively. The Wave 2 also features a USB and USB-C port to charge external devices.  

The settings on the Wave 2 are adjustable directly via the unit, or you can use the EcoFlow app with Wi-Fi or Bluetooth. It’s extremely quiet at just 44 decibels and did not disturb us during any of our testing locations.

One of the biggest advantages of this unit is that it does not need to be vented. While this is true, we found when using it indoors, it works best if it is vented. We tested it in a small office with no windows, and while it did cool the space directly in front of the air vent, it had a hard time keeping up with the output airflow, which was warm. This isn’t an issue when using the unit outdoors, and we found when using it at outdoor events or camping, it worked great for keeping us cooled off.

What to Consider When Choosing a Portable Air Conditioner

Take some time to think about the various features and functions available in portable air conditioners before deciding on a specific product. You’ll want to consider factors like single- or dual-hose configurations, energy consumption, cooling capacity, room size, and even the noise produced by the portable AC before making a purchase.

Single vs. Dual Hose

  • Single-hose AC units pull warm air from the space around it, cool the air, and dispose of heat and moisture through a hose that leads outside. These models are typically cheaper than their dual-hose counterparts but have one significant drawback: Since the unit relies on already-cooled air to bring down the temperature of the condenser, considerable energy goes to waste.
  • Dual-hose AC units have both an intake and outtake hose. The intake hose draws in outdoor air to bring down the temperature of the condenser. The separate outtake hose disposes of the heat, humidity, and used air from the indoor space. While pricier, dual-hose units are more efficient and generally the wiser option, particularly for larger spaces.

Functions

Portable air-conditioning units have several different functions available depending on the product, including standard AC, evaporative air coolers, heaters, air purifiers, and humidifiers/dehumidifiers.

  • Standard AC units function by pulling in stagnant air from the room and pumping it over cold coils to cool the air. Warm air and excess moisture are expelled to the outside through a hose. This function rapidly cools the air in the room.
  • Evaporative air-cooler models typically use ice or cold water to cool the air in the room. The unit uses a fan to pull warm air in through a wet sponge or bucket of ice, then the same fan pushes the cool air out through the front of the portable air conditioner to cool the room. However, this function does not have the same level of cooling power as a standard portable AC.
  • Heaters can sometimes be built into portable air conditioners, giving you the ability to switch between heating and cooling and enabling use throughout the warm and cold months of the year.
  • Air purifiers are designed to pull in dust, dirt, hair, and other contaminants, trapping them in a filter and pushing out cleaner air. While some portable ACs include an air purifier function, this is a relatively rare and high-end feature.
  • Humidifier/dehumidifier models increase or decrease the moisture in the air. Many portable AC units can act as dehumidifiers to pull in moisture and push out drier air, though it’s less common for a portable air conditioner to have a humidifier mode. Evaporative air-cooler ACs act as humidifiers while also cooling the air, so a specific humidifier setting isn’t as necessary.

Room Size

The size of the room matters when choosing a portable air conditioner, so be sure to select a unit with the appropriate output for cooling the space. Portable air-conditioner manufacturers will often provide the output of the device in BTUs, with each BTU equal to the amount of heat that the AC unit can remove from a room. The output of a portable air conditioner ranges from about 3,000 to 15,000 BTUs.

Typically, the cooling area of an evaporative air cooler is measured in cubic feet per minute (CFM). Calculate the necessary CFM for the target room by multiplying the length, width, and height of the room to find the volume, then dividing the total by 2: CFM = (L x W x H) divided by 2.

According to Glenn Gault, a heating and air conditioning expert, a common mistake consumers make is purchasing a portable air conditioner for the kitchen using the same criteria as they would for a bedroom or living room. “Cooking appliances generate significant heat, making it harder for the AC unit to cool the room,” he says. “Keep in mind that if you choose a portable AC unit for a kitchen, you need to increase the capacity by about 4,000 BTUs from what you would need for the room size.” 

Energy Efficiency

Air conditioners with a BTU rating of 10,000 or higher are typically the most efficient at cooling a room, but the higher the BTU, the louder and heavier the model. Most AC units also come with an Energy efficiency Ratio (EER). A higher EER rating equates to greater efficiency; EER indicates the ratio of the air conditioner’s BTUs per hour to its power input, measured in watts.

In other words, cooling a larger space requires more BTUs, and some units are built with greater energy efficiency than others. The EER weighs output and input against each other to show how effective and efficient the unit will be. Many portable air conditioners have EER ratings between 8.5 and 10; any rating higher than 10 is ideal.

Portability

If the intent is to regularly move the AC unit around, consider investing in a smaller portable AC that’s easy to pick up.

Look out for portable air conditioners with handles on the side or back of the unit, which can make it easier to pick it up and adjust the positioning. Some portable ACs have wheels on the bottom of the unit as well. This is an especially helpful feature to move the air conditioner over a flat surface without needing to lift it off the ground.

Noise Level

In the past, air conditioners, fans, and heaters were known to produce very high noise levels due to the hum of the motor, fan blade rotation, and the force of the expelled air. Today, product advancements have significantly reduced the noise produced by these devices through intelligent engineering and enhanced insulation that dampens the sound.

The average AC unit now produces about 50 to 60 decibels (dB) of sound, while the quietest portable air conditioner options may only be 40 to 45 dB. For perspective, the sound of a person whispering is about 30 dB, a normal conversation is 55 to 65 dB, and ambient noises in a busy office or restaurant range from 70 to 80 dB.

Additional Features

Standard portable air conditioners are easy to use, allowing you to circulate cool air throughout the home. That said, some products come with extra features that can make them more convenient and user-friendly:

  • Timers keep the portable air conditioner on for a set period of time. Once it reaches the end of this period, it will automatically shut off instead of running all day, which helps keep electricity costs low.
  • Programmable settings on a portable air conditioner can include fan-speed settings, set temperatures, temperature ranges, sleep mode, and more. These settings are meant to provide complete control over the unit. A smart portable air conditioner can even integrate with smart-home systems like Amazon Alexa or Google Assistant to control the AC unit using voice commands.
  • Night lights are a good option for those who walk around a fair amount at night, since the added illumination helps prevent injury (like accidentally kicking the air conditioner).

Installation and Maintenance

One of the main benefits of choosing a portable air conditioner is its typically easy installation. Standard portable AC units need an available power outlet and a place for the hose to filter out excess moisture and hot air. This is accomplished by running the hose through a custom frame that sits inside an open window, creating a seal around the window and around the hose to prevent leaks.

“You don’t need to hire a professional for portable air conditioner installation, and all you need to start it working is to fit an exhaust hose to a window for venting hot air outside,” says Gault.

Alternatively, evaporative air coolers don’t have a hose that has to run outside, but they do need cold water or ice in the sponge or bucket to cool the air that passes through the unit. Both styles require regular cleaning and may need to be drained if they have a dehumidifier function that collects water from the ambient air.

FAQs

These high-efficiency devices are a great option to keep your home cool in warm weather. For more info on how to shop for, use, and set up portable air conditioners, read on for answers to some of the most common questions.

Q. What are the benefits of a portable air conditioner?

A portable air conditioner is specifically made to be moved around an indoor space so that it can be set up wherever it’s needed most.
These devices do take up some floor space, but they are generally accepted in condos and apartments, as some landlords ban the use of a window air conditioner due to the risk of the unit falling out of the window.

Q. How much space does a portable air conditioner cool?

Depending on the power output of the portable air conditioner, these devices can cool spaces from about 100 to 800 square feet. For example, the options on our list of top picks can cool rooms of 400 to 725 square feet and come with both air conditioners as well as dehumidifiers.

Q. Can I use a portable air conditioner in a room with no windows?

Portable air conditioners that have an evaporative air cooler function can be used in a room with no windows. The air is cooled when it passes through a cold wet sponge or a bucket of ice, and then it flows back out into the room without needing to be filtered outdoors.

Q. Do portable air conditioners use a lot of electricity?

The output of a portable air conditioner is typically given in BTUs, while electricity is measured in kilowatt hours (kWh). One kWh is equal to 1 kilowatt of power per hour. On average, a 7,000 BTU portable AC uses about 2.2 kWh; a 10,000 BTU unit uses about 2.9 kWh; and a 14,000 BTU AC unit uses about 4.1 kWh.
