The 7 Best Portable Air Conditioners of 2022

The Spruce / Chloe Jeong

You might be used to window-mounted air conditioners, but there are plenty of benefits to portable air conditioners, as well. “A portable unit can be on wheels and rolled from room to room and includes a tube to exhaust heat out of a window or through an opening in a wall,” explains Chris Roth, CEO and owner of National Technical Institute. He adds that they're usually easy to store and very versatile. To find the best portable air conditioners, we researched a wide range of models from top brands, taking into account factors such as their cooling abilities, energy efficiency, noise level, installation requirements, and other features.

The best option you can buy today is the LG Electronics LP1419IVSM Portable Air Conditioner, which is extremely quiet and has Wi-Fi capabilities, so you can control it right from your phone. 

The following are the best portable air conditioners to keep your home cool this summer.

What We Like
  • Quiet operation

  • Powerful dehumidifier

  • Easy to install

  • Smart features

  • Storage tray for accessories

What We Don't Like
  • Fairly short vent hose

The LG LP1419IVSM 14,000 BTU Portable Air Conditioner is a top choice thanks to its surprisingly quiet operation, smart capabilities, and energy-saving design. Its dual inverter technology uses 40% less energy than similar sized portable air conditioners, and on its lowest setting, the unit is only 44 decibels—significantly quieter than many other units, so it won't disrupt your sleep. This portable AC is suitable for spaces up to 500 square feet, which is roughly 20 x 25 feet, and it’s rated at 10,000 BTU DOE. Also, its sleek outer shell won't be an eyesore in your home.

This portable air conditioner offers three cooling and fan speeds, as well as an auto cool setting, and you can control it via the digital control panel, LCD remote, or your smartphone via the LG ThinQ app. Thanks to its Wi-Fi connectivity, the unit can even be connected to Amazon Alexa or Google Assistant, so you can give it voice commands to turn on the AC while you're cooking or working out. It’s mounted on easy-rolling casters for simple movement, and it has an auto-swing air vent that ensures air is distributed throughout the whole room. Other features include a 24-hour on/off timer, auto restart after power failure, and a filter check light. 

In terms of installation, the AC comes with a window vent kit that’s easy to install, but keep in mind that the vent hose is fairly short at just 35.5 inches, so the unit has to be close to the window. When it’s time to pack the air conditioner back up, there’s a storage tray on the back of the unit where you can easily stash the window kit and hose, making it simple to keep everything together.

It has a remote control and top-mounted LED display where you can change the settings, but unfortunately, the display can’t be dimmed or turned off, so it’s highly visible at night. The AC has a self-evaporating design when in cooling mode, meaning there’s no need to drain off any water, and it has a 24-hour timer, to boot. The window installation kit works in horizontal or vertical window openings between 20.5 and 59 inches, but it can be somewhat tricky to secure, as the included foam isn’t the best quality.

What We Like
  • Indoor or outdoor use

  • Manual or continuous fill

  • Large coverage area

  • Lightweight

  • Easy to operate

What We Don't Like
  • Not effective in high humidity

  • Unattractive design

An evaporative cooler like the Hessaire MC37M is a more affordable cooling option for those who live in low-humidity areas. Instead of using a refrigerant to cool down your space, this swamp cooler pushes air through a water-soaked filter, lowering the temperature and adding humidity to the air. The technology uses significantly less energy than traditional air conditioners, and this model has a 10.3-gallon water tank that can run for several hours at a time, cooling an indoor or outdoor living space of up to 950 square feet. 

The Hessaire MC37M has a manual design with three fan speeds and option oscillation, and for continuous operation, you can hook it up to a garden hose, which will automatically refill the water tank when it gets low. The unit is mounted on heavy-duty locking casters and is fairly lightweight when empty, making it easy to move around your home, but it does have a fairly large, bulky appearance. Also, keep in mind that swamp coolers are only effective in low-humidity climates—they won’t do much if you live somewhere with hot, humid weather.

What to Look for in a Portable Air Conditioner

Type

There are several styles of portable air conditioners that you may want to consider as you shop. First, there are classic air conditioners, which use a refrigerant to cool down the air in your home. These units are ideal for both lowering the temperature and removing humidity from the air, but they tend to use more energy and cost more upfront. 

There are also single and dual-hose options. Single hose options pull air from the interior of your home, cool it down, then expel excess heat through a single hose vented out a window or door. Dual-hose models, on the other hand, use one vent hose to pull in fresh air from the outside and a second to expel heat, allowing them to work more quickly and efficiently. Dual-hose air conditioners are typically larger and more expensive than single-hose options. 

Alternatively, those who live in low-humidity climates may want to opt for an evaporative cooler. These less-expensive models work by pushing air through a water-soaked filter, which cools down the air while increasing humidity. Also called swamp coolers, these units can often be used both inside and outside, and they typically require less energy to run. However, they need a steady supply of water to operate—some can be hooked up to a garden hose, while others require manual refills.

Room size

One of the most important factors when choosing a portable air conditioning unit is the recommended room size. “Load calculation helps to determine the appropriate size of the AC your home will require,” explains Roth. “It is done by matching your home’s thermal characteristics with cooling capacity in BTUs.”

Generally speaking, a higher BTU rating means that the unit can cool a larger room, but as you look at different portable air conditioners, you’ll notice that there are often two BTU ratings—a DOE or SACC rating and an ASHRAE rating—which can make things a bit more confusing. 

BTU ratings were traditionally calculated based on criteria from the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), which evaluated their ability to cool a room at 80 degrees Fahrenheit and 51 percent humidity. However, in 2017, the Department of Energy (DOE) introduced the concept of Seasonally Adjusted Cooling Capacity (SACC), which evaluates a portable AC’s cooling abilities in multiple conditions to more accurately depict real-life use. As you may have noticed, DOE BTU ratings are always lower than ASHRAE ratings, and the former is typically considered more accurate.

Condensation drainage

Unlike window air conditioners, which are able to drain moisture to the exterior of your home, portable air conditioners collect moisture from the air inside the unit, and this liquid needs to be removed periodically, especially during humid weather. Some units have a water tank or tray that must be manually emptied, while others have a drain hose attached to an exterior window. More advanced units sometimes offer self-draining systems that recycle moisture back into the air to eliminate the need for drainage. The best setup for you will depend on your climate, how much condensation your air conditioner collects, and the layout of your room.

FAQ
  • When should you choose a portable air conditioner over a window unit?

    While window-mounted air conditioners are excellent long-term cooling solutions, they tend to be heavier, harder to install, and less versatile than their portable alternatives. Portable air conditioners tend to be the better option if you need to be able to move your unit from room to room, or even between buildings.

  • How do you install a portable air conditioner?

    Non-evaporative portable air conditioners will need to be set up near a window or vent so that their exhaust hose has somewhere to pump hot air out of your home. These units usually come with a window adapter that will create an air-tight opening for the hose. Installation generally shouldn't take longer than 15 to 20 minutes.

    Evaporative portable air conditioners don't need to be hooked up to a window or vent, but they work best in a well-ventilated area. Keeping yours near an open window will prevent the room from getting too cold or clammy.

  • How do you empty a portable air conditioner?

    When the time comes to drain your portable air conditioner (which will vary depending on your model and how often you use it), you can empty the water tank manually by placing a pan under the unit and letting the water drain into it. If your unit comes with a drainage hose, you also have the option of attaching the hose and running it down a floor drain.
