School's (been) out, and the strong summer sunshine is here in full effect. And as technology and innovation continue to collide in time, an incredible invention in the form of portable air conditioners is starting to sweep the country and world at-large.

The advent of these new standalone air conditioning units for ultimate portability has been paramount and is very easy to see why it is a hot commodity in comparison to the high-electricity costs of traditional central home cooling systems or overly pricey, noisy window AC units.

The growing demand for a compact, lightweight, yet powerful personal air conditioning unit to beat the hot and heavy humid summer heat no matter where you go or where you reside has been quite impressive. But this should come as no shock, yet it is easy to grasp why these air cooling, purifying and even humidifying devices are flying off the online shelves and into the homes of tens of thousands of people as the summertime heat reminds us all who is the boss when it wants to be.

That said, air conditioners aren’t just convenient: they’re life-savers. As temperatures rise during the summer, air conditioners keep you safe, sane and give you the ability to stay cool and comfortable to avoid overwhelming heat, fatigue or exhaustion, dehydration or even heat strokes.

Today, technology has made it easier than ever to find a good, affordable air conditioner. You can buy a portable air conditioner today capable of cooling an entire room and even some homes.

And the best part is, you don’t have to spend a fortune to get a good price on a personal air conditioner for portable use anymore. Whether you want to spend $50, $500 or $5,000 on a portable air conditioner, you can find an effective unit for your budget and will be better than nothing at all by opting to use an innovative alternative to ACs or fans.

How We Ranked the Top Portable AC Units

Our editorial team considered all of the following factors when building our rankings:

BTUs: Portable AC units range in size from 8,000 to 14,000 BTUs, which means they cover rooms ranging from 200 to 500 square feet. We featured models with all different sizes for different needs.

Cooling Power: Some portable AC units cool rooms more effectively than others. Some claim to offer a certain power output, yet struggle to cool a medium-sized room. We considered cooling capacity in our rankings – after all, that’s why you’re buying a portable AC unit.

Portability Features: Some portable air conditioners have rolling wheels. Others are lightweight. This guide is specifically for portable air conditioners, and we emphasized air conditioners that were easy to use in multiple rooms.

Usability: Some portable AC units have remote controls. Others have touch panels or dials. Some smart AC units even have Wi-Fi connectivity or a smartphone app. You want to use your portable AC unit, so we emphasized air conditioners with strong portability.

Appearance: Your portable AC unit takes up significant space in your room. Most units are large, so it helps when they have a nice appearance or design. Some portable AC units are ugly, while others look sleek, minimalistic, or futuristic.

Modes & Speeds: Good portable AC units have multiple modes and speeds, making it easy to customize cooling however you like. You can have maximum cooling

Noise: It’s easy to design a loud portable air conditioner. It’s hard to cool air and run quietly. Good portable AC units do both.

Price & Value: The portable air conditioners above range from as little as $25 to over $600. We featured a range of products for all different prices, although we emphasized good value at every price.

Charging & Power: Some portable AC units use battery power. Others can be recharged. Some plug into normal electrical outlets.

Filtration: Most air conditioners do not filter the air. They just cool it. If you live in an environment with clean air, then that’s fine. However, if you live in an environment with dirty air, or if your air conditioner is sucking air from outside, then you may want added filtration. Some of the top-ranked portable AC units on our list came with UV filtration or other filtration systems.

Humidification: Some portable AC units do more than just cool the air. They also affect the humidity of the air. Some are dehumidifiers that remove moisture from the air, while others are humidifiers that raise humidity of the air. Depending on whether you live in a dry or humid climate, you might pick one or the other.

Extra Features: We considered extra features in our rankings. Yes, the primary goal is to cool a room, but we appreciate added features like lights, roller wheels, LED displays, and remote controls.

Energy Efficiency: Energy efficiency isn’t just about the environment: an inefficient portable AC unit could add hundreds to your electricity bill every month. Many are surprised to buy a lower-quality portable AC unit to cool their home, only to discover they weren’t willing to spend $400 extra per month to cool the home. For maximum efficiency, look for an Energy Star label on your portable AC unit. This label means the unit is rated to meet certain energy efficiency standards.

Warranty: Good portable AC unit companies stand behind their products, offering strong warranties and coverage. A higher-end portable AC unit may have up to 5 years of warranty coverage. Some of the units listed above have 6 to 12 months of warranty coverage. Others have limited warranty coverage at all. Generally, we preferred portable AC units with lengthy, full-featured warranties.

Who Should Use a Portable AC Unit?

Portable AC Unit

People use portable AC units for all different reasons. Generally, however, people use portable AC units because they want to stay cool.

Some people buy a portable AC unit because it’s a smarter option than installing a complete HVAC system or central air conditioning system. You might be renting a room, for example. You can’t install a complete home air conditioning system, but you can buy a portable air conditioner.

Portable AC units are also popular for dorm rooms, offices, and similar settings. If you spend a lot of time in one room and want to keep that room cool, then a portable AC unit may be the best option.

Portable AC units are also ideal for bedrooms. Your home might be comfortable during the day but a little too hot at night. Many people install a portable AC unit in a bedroom to keep the room cool all night long.

Others install a portable AC unit if you spend a lot of time in one room of your home. Your needs might not justify a full AC system, but a portable AC unit is ideal for an office, living room, bedroom, or other room in your home where you spend most of your time.

In other homes, a portable AC unit is simply the most economical option. You might have a large home – but you only spend time in one or two rooms. Installing and running an air conditioning system isn’t worth it, and a portable AC unit is better.

Others buy a portable air conditioner for working out. If you overheat when working out, for example, then you might buy a portable neck air conditioner. It’s ideal for indoor or outdoor workouts in any environment, and it’s discreet enough to place under your shirt without anyone noticing.

Some people just run hot. If you find yourself getting hot and sweaty every time you leave the house, for example, then you might just run hotter than other people. There’s nothing wrong with that – but you might want to invest in a portable neck air conditioner to make yourself more comfortable.

How Do Portable AC Units Work?

Portable AC units cool the air in different ways.

Some of the basic units above simply blow air onto your face or body. They don’t cool the air at all: they simply blow air towards you, which could provide some relief on a hot day.

Other AC units take things further. They use condensation evaporation systems and other technology to cool incoming air and expel colder air.

A traditional AC unit is part of your home’s heating and cooling system. It draws energy out of your house and transfers it to the outside air. The air conditioner changes the temperature, humidity, or general quality of the air. It makes your home cooler, transferring warm air outdoors and replacing it with cooler air.

To cool your home, an air conditioner uses either a split system or central air:

Central Air: A central heating and cooling system provides cool air through ductwork inside your home (your HVAC system). The system draws warm air inside, then expels that air outside to remove its heat.

Split System: With a split system, a compressor condenses and circulates the refrigerant through the outdoor unit, changing it from a gas to a liquid. The liquid is forced through the indoor evaporator coil or cooling compartment. A fan inside the unit circulates the inside air across the evaporator fins. The fins exchange the thermal energy with the surrounding air, and the refrigerant turns from liquid into vapor, removing heat. The end result is cool air, and the unit sends that cool air back into the home. Once this process is complete, the system turns the vapor back into a liquid, removing heat. The cycle begins again.

Portable air conditioners work in a similar but more straightforward way. A freestanding portable air conditioner works like this:

Single hose portable air conditioners pull stagnant air from inside the room, using a motor inside the unit to cool the air and circulate it throughout the space; these units also take excess warm air and moisture, funneling it through the hose and out the window

Dual hose portable air conditioners pull fresh air from outside through one hose, then circulate cool air throughout the space; the unit pulls excess warm air and moisture through the unit, exiting through the opposite hose

Most portable air conditioners have a window venting kit to expel exhaust (just like the venting system of your clothes dryer)

Some portable AC units have water reservoirs to dehumidify the room; you need to empty the reservoir periodically (although some units come wit a drainage hose)

Other models are self-evaporative, which means they evaporate much of the moisture and direct the exhaust through the air duct, reducing the number of times you need to empty the container

Some portable AC units come with window mounts. You place the AC unit on a window, then use one or two ventilation hoses to ensure safe operation. Most kits are easy to install without specialized tools or DIY skills.

Some portable AC units are more portable than others. Some portable AC units have rolling wheels and other portability features. Others have wall or window mounts for more permanent use.


The most important thing to consider when buying a portable AC unit is size. Portable AC units vary widely in terms of size, ranging from 8,000 to 14,000 BTU models. Depending on the size of your home or room, you may need a smaller or larger model.

8,000 BTU: Cools a room of about 200 square feet

10,000 BTU: Effective for rooms up to 300 square feet.

12,000 BTU: Generally sufficient for 400 square feet rooms.

13,000 BTU: Covers space up to 450 square feet.

14,000 BTU: Typically large enough for a 500 square foot room.

Consider the size of your room before buying one of the portable AC units above.

You also need to consider single hose vs dual hose ventilation. Most portable AC units need to vent exhaust through a window to be effective. Some units come with a single hose setup, while others come with a dual hose setup. With a single hose setup, you have the same hose for both the intake of fresh air and the exhaust of fresh air. That may sound good – but the AC unit is less efficient because the hose is doing twice the work. With a dual hose setup, you have one hose for input and one hose for output, leading to more efficient operation.

Other Features

All portable air conditioners remove some moisture from the air. That’s just how air conditioners work. However, certain portable AC units have a dedicated dehumidifier, allowing you to reduce humidity in your home without adding cold air. If you live in a humid environment and want to reduce humidity, then get a portable AC unit with effective dehumidification.

Noise also plays a crucial role in portable AC units. Cheap, poorly-designed portable AC units sound like jet engines. Higher-end models provide similar air conditioning – but without the loud noise. Noise level isn’t important to everyone. However, we appreciated portable AC units that had multiple modes for different speeds and noise levels.

Portable AC units are designed with minimal maintenance in mind. However, the moisture collected by your portable AC unit needs to go somewhere. The unit removes moisture from the air, and you have to get rid of this moisture. Some portable AC units come with a pan or hose. You may need to empty the pan regularly to avoid leaks. Some AC units are self-evaporative, which means they eliminate moisture on their own without a hose or pan.

FAQs About Portable Air Conditioners

The world and its people are on the hunt for the best portable ACs during these overly hot summer days filled with humidity and dry heat. The following is the most comprehensive set of question and answers pertaining to portable air conditioners found on the Internet. Enjoy and please be sure to leave a comment or suggestion for anything we have missed about using portable AC air conditioning units.

Q: What is a portable air conditioner?

A: A portable air conditioner is a device that cools a home while still being portable. It works similar to a traditional central air conditioning system but can be carried wherever you need it to go.

Q: Are portable air conditioners energy efficient?

A: A good portable AC unit is energy efficient. Look for the Energy Star logo for maximum efficiency. Bad portable AC units can suck up energy, costing you hundreds.

Q: Do all portable air conditioners need to be vented?

A: Most medium to high-end portable air conditioners need to be vented, although lower-end or cheaper models may not need a window vent kit. Some models above require venting systems, while others do not.

Q: Do portable air conditioners really work?

A: Yes, portable AC units work as advertised to cool a room. They won’t cool an entire 2,000 square foot home, but if you have reasonable expectations for your AC unit, it should get the job done.

Q: What is a window vent kit?

A: Many portable air conditioners come with a window vent kit. These kits are typically made from plastic. They’re a piece of equipment that sits on the windowsill, connecting to the exhaust hose of the AC unit.

Q: How does a portable air conditioner work?

A: Portable air conditioners work in different ways. Generally, they extract moisture and hot air from a room, replacing it with cool air. Some use single or dual hose systems to ease this process.

Q: What is a neck portable air conditioner?

A: Some devices market themselves as neck portable AC units. These units aren’t technically air conditioners: they’re just fans worn around the neck. They can blow air against your body, cooling you during a workout, at home, or at work.

Q: Do I need to install a window mount for my portable AC unit?

A: Some portable AC units come with window mount kits. You can install this kit for better operation. Or, you can use a hose system for similar effect. Generally, portable AC units are designed to be portable, and you should not have to install anything if you don’t want to.

Q: Can a portable air conditioner cool multiple rooms?

A: A good portable air conditioner (14,000 BTUs) cools rooms up to 500 square feet. Most portable AC units aren’t designed to cool multiple rooms at once. However, with the right fan setup or circulation, it’s possible some cool air could circulate.

Q: How large of a room can a portable air conditioner cool?

A: A good portable air conditioner cools rooms up to 500 square feet. An average-sized air conditioner effectively cools rooms of 200 to 300 square feet. That’s enough power for any office, bedroom, or dorm room. At the higher end, it’s enough power for a living room, kitchen, or other large rooms in your home.

Q: What happens if I can’t vent my AC unit?

A: If you have a portable AC unit that requires venting, then you need to find a venting option. Otherwise, the air conditioner will not cool your home efficiently.

Q: Can I vent my portable AC through a dryer vent?

A: You should be able to vent your portable AC unit through a dryer vent, although it may or may not be a good idea. If the diameter of the AC hose fits the dryer vent perfectly, then there should be nothing wrong. However, most dryer vents have a much smaller diameter (4 inches) than a portable air conditioning system.

Q: How long is the portable AC unit exhaust hose?

A: Most portable AC units come with an exhaust hose 3 to 4 feet long. You can buy longer hoses or extender hoses at any hardware store – say, if you’re not close to a window.

Q: What’s the difference between a single hose and dual hose unit?

A: A single hose unit moves air in and out of the device through a single hose. It uses less energy, but it’s also less powerful for cooling a room. A dual hose unit moves air in through one hose and out through another hose, using more energy but cooling rooms more efficiently. Generally, dual hose options are the better option for cooling larger rooms.

Q: Are portable air conditioners safe?

A: Portable air conditioners are safe. Portable AC units do not emit carbon monoxide. The only time a portable AC unit could be dangerous is if you live in a toxic city with bad-quality outside air. The portable AC unit could draw toxic outside air into your home. Otherwise, however, portable AC units are perfectly safe to use when installed correctly.

Q: Do portable air conditioners release carbon monoxide?

A: Portable air conditioners do not release carbon monoxide. The only time a portable AC unit could create carbon monoxide is if the intake air (the air coming from outside your home) is rich with carbon monoxide (say, if the hose is next to a grill, a portable generator, a running car, or another source of carbon monoxide). All of these are extreme scenarios, and portable AC units are generally safe to use.

Q: What’s the difference between a portable AC unit and an evaporative cooler?

A: Portable AC units and evaporative coolers achieve the same effects but in different ways. An evaporative cooler, also known as a swamp cooler, uses water and evaporation to make a room feel cooler. You add water for the cooler to work, and the cooler does not require ventilation. They’re popular in garages and workshops.

Q: Are portable air conditioners loud?

A: All portable air conditioners make noise. Good portable AC units cool a home without making much noise, although some models are excessively loud.

Q: Can I reduce sound from my air conditioner?

A: You can lower the noise on your air conditioner in several ways. Start by lowering the fan speed. Or, place the AC unit on a softer surface instead of a hard floor (like carpet instead of hardwood). This lowers the vibration of the compressor.

Q: What type of electricity do portable AC units use?

A: Most portable air conditioners use standard home electricity: you plug them into an electrical socket. Others use lithium ion batteries or other battery power.

Q: Will portable AC units cool a garage?

A: Portable AC units are not ideal for garages, although a higher-end model may provide some level of cooling. A 14,000 BTU portable AC unit can cool a 500 square foot space, for example, which may be large enough for a smaller garage.

Q: Is a portable air conditioner the right choice for me?

A: Portable air conditioners are the right choice for certain people in certain situations. If you live in an apartment, rent a room, or just want to cool a single room of your home (like a bedroom), then a portable AC unit may be the right choice for you. Some HOAs do not allow window AC units, which means you need to buy a portable AC unit or install a central air conditioning system. Millions of homes around the world use portable air conditioning systems to effectively cool homes.

Q: Where can I buy a portable air conditioner?

A: You can buy a portable air conditioner through any standard electronics retailer, appliance store, Amazon, Walmart, and other stores.

Q: How much should I spend on a portable air conditioner?

A: A lower-end portable air conditioner costs $200 to $300, while mid-range models are priced at $300 to $500. At $600 and above, you can get a high-end portable air conditioner capable of cooling a 500 square foot room or larger.

Q: What happens to the moisture pulled from the air?

A: Most high-end portable AC units have self-evaporative technology, which means any collected moisture is evaporated and expelled out the back of the unit. Some portable AC units have pans where water collects, and you need to empty these pans periodically.

Q: Can I use a portable air conditioner in a room without a window?

A: Portable air conditioners, like any AC units, need somewhere to release heat. A window is the best and most convenient way to release heat, although there are other exhaust options. If you’re in a room with no window, then you could install a small vent leading outside or buy a longer exhaust hose.

Q: What should I consider when shopping for portable air conditioners?

A: The three main things to consider when shopping for personal air conditioners including size (like number of BTUs), single or dual hose design, and noise level.
