Portable Air Conditioner Unit Buying Guide

What is a Portable Air Conditioner?

Portable air conditioners are actually quite amazing little devices.

At their core, portable AC units are self-contained, mobile appliances that allow you to regulate the temperature inside a single room or connected rooms without a wall between them.

Portable air conditioners are positioned on the floor and some models include wheels for easy transport.

In comparison to both wall air conditioners and window AC units, what makes a portable air conditioner unique is just that–the fact that it’s portable.

This means that you don’t have to permanently install the appliance, thus enabling you to easily change the location of the stand up AC unit without having to make any structural changes to your home or carry a heavy piece of equipment around.

Some people use portable air conditioners as their main source of cooling because a central air conditioning system doesn’t exist in their house.

Others, use portable AC units as a way to save money by using their central air conditioner less often and only cooling the room (or rooms) that they frequent most.

Types of Stand Up Air Conditioners

When you’re shopping for a portable air conditioner, you’ll find that come in two configurations:

  • Single exhaust hose
  • Dual hose units

Essentially, every portable AC system has to vent hot air to the outside and cool down the internal components.

Otherwise, that hot air would circulate back into the room and the unit would overheat.

Although there’s not much evidence that either type of portable AC is a better option (single hose vs dual hose), it’s still good for you to know how each model works.

That way, you can make the best decision possible for which portable air conditioner to choose.

Single Exhaust Hose AC Units

This type of portable air conditioner has one exhaust hose coming out of the back of the unit.

After the room air is pulled into the air conditioner, it flows across the internal coils to be chilled before being delivered back into the room.

Some of that air is used to cool down the internal components of the portable air conditioner.

After the air is used for cooling, it’s then pushed to the outdoors through a single exhaust hose.

A top benefit of using a single hose air conditioner is that these units are much easier to set up and move to other rooms of your house.

Dual Hose AC Units

A dual hose air conditioner has two hoses coming out of the back of the unit.

The first hose on a portable air cooler is used to draw outdoor air into the unit to cool down the internal components.

The second hose in a dual hose system is an exhaust hose. Its purpose is to send the air that’s been used to cool down the portable AC unit to the outside.

The top benefit of using a dual hose air conditioner is that these units can cool down a large room much quicker because the design is more efficient.

With two hoses, these types of portable ACs don’t have to work as hard as single exhaust hose units.

Portable Air Conditioners & Dehumidification

When you’re buying a stand up air conditioner, another thing you need to be aware of is dehumidification.

Dehumidification is the process where a portable air conditioner removes moisture from the air, thereby lessening humidity to make you feel cooler.

When dehumidifying, most portable air conditioners tend to collect this water vapor on its coils and depending on the unit you choose, the water can be removed in one of three ways:

  • By dumping out a collection bucket
  • Routing an attached tube to a floor drain
  • Automatic self-evaporation which removes the collected moisture for you

If this process of maintaining your portable air conditioner concerns you, keep this information in mind when selecting a portable AC unit.

The automatic self-evaporation method would probably be the best type for your needs and it’s available on the best portable air conditioners reviewed on this page.

Top Features to Look for in the Best Portable AC Units

Top Portable Air Conditioner

Now, before you go off and buy the best portable air conditioner with the highest reviews, we recommend that you consider these top features below.

Choosing a portable AC unit that has one or more of these features will help you get a high-quality air conditioner that serves your cooling needs well into the future.

  • Dehumidifier Mode — Sometimes it’s not the indoor temperature that’s making you feel hot but the humidity that’s in the air. And, picking a portable air conditioner with a dehumidifier mode will remove moisture from the air. Thus, you and the room air will feel cooler without lower energy costs. Some portable ACs are so effective that they can extract up to 100 pints of water out of the air per day.
  • Heat Mode — If you’re investing in a portable floor AC unit for the long-term, why not get one that also includes a heating function? That way, you can use the AC unit all year round. Having a heat mode means that your portable AC can deliver warm heat in the winter and cool air conditioning in the summer.
  • Sleep or Night Mode — These modes automatically adjust your portable air conditioner to a quiet setting so you can enjoy a more peaceful sleep. They also adapt the temperature setting so the room doesn’t get overly hot or freezing cold.
  • Remote Control — Not all portable AC units include a remote control, so if you want to be able to operate the air conditioner from the couch or your bed, look for this feature.
  • Smart Wi-Fi Control — Similar to a remote, not all portable ACs have smart Wi-Fi controls. If you want to operate the air conditioner from your smartphone or other mobile device, then a portable AC unit with smart Wi-Fi capabilities is a must-have feature. This function also lets you set up personalized cooling schedules for various times and days throughout the week.
  • Timer Function — This is a useful setting you want to set your portable air conditioner up to automatically go off after a set number of hours. Many portable air coolers feature a 24-hour countdown clock regardless if it comes with a remote or has smart enabled features.

Benefits of Portable Air Conditioners

Portable air conditioners offer many advantages for home cooling.

Here are just a few of the benefits of freestanding air conditioners:

  • Easy to move from room to room. The convenience of being able to move the air conditioner between rooms is enough for many people to choose portable air conditioners over other types of units.
  • Easy to install on your own. They can be set up in a matter of minutes after taking the unit out of the package. And not special tools are required for installation.
  • Much cheaper to use than a central air conditioning unit. These air conditioners use about one-eighth of the electricity required to run a central air conditioning system. That comes out to about $6-15 per month at the bare minimum to cool a room.
  • Doesn’t take up much physical space. Most units are under 24 inches in height and smaller than 18 inches wide.
  • Can often be used in rental homes and apartments without landlord concerns. Because no part of the unit hangs out of the window, portable air conditioners are the best options for people who can’t install any other type of air conditioning unit in their home.

Common Questions About Stand Up Air Conditioners

Best Portable AC Unit

What is BTU and What Does it Mean?

BTU stands for British Thermal Unit and it’s the standard unit of measurement for air conditioners.

Technically speaking, BTU is the amount of thermal energy needed to raise the temperature of one pound of water one degree Fahrenheit.

In the HVAC industry, BTUs also measure the quantity of heat an air conditioning unit can remove from a room per hour.

When you’re dealing with portable ACs or window ACs, the more BTUs there are, the large a room those units can cool.

Higher BTUs also means a higher price for the product since more energy is required for more powerful cooling.

How Many BTUs Do You Need to Cool a Room?

When you’re comparing portable AC units it’s best to choose a model that meets the demands of the room you’re going to use it in.

To pick the most appropriate portable air conditioner, you’ll want to match the British Thermal Unit (BTU) to the total square footage of the room.

While that may seem like a hard thing to do, it’s actually quite easy.

To get the square footage of a room, all you need to do is measure the width (in feet) and multiply it by the length (in feet).

Multiplying those two numbers gives you the square feet you need to match up to a particular BTU size.

For example, a 20′ x 30′ room = 600 square feet.

With that number in hand, you can find a portable AC unit with the right BTU rating that can handle that amount of space.

To make that process simple for you, here’s an easy to read chart that takes all of the confusion out of it.

Room Area To Be CooledBTU Capacity Needed
up to 250 sq. ft.6,000 BTU
up to 350 sq. ft.8,000 BTU
350 to 400 sq. ft.9,000 BTU
400 to 450 sq. ft.10,000 BTU
450 to 550 sq. ft.12,000 BTU
550 to 700 sq. ft.14,000 BTU

Note: Some portable AC units may cool more or less than the room size listed above. So, check the technical specifications to be sure. This chart is just a general guide.

Are Stand Up AC Units Any Good?

top rated portable air conditioner

Yes, portable AC units are good appliances for cooling a room.

Portable air conditioners are energy efficient devices that draw hot air out of a room and expel it outdoors.

What makes portable AC units good for people is the fact that these models are easy to move from room to room and don’t require much set up to get running.

These ACs also provide excellent cooling for a low price.

Do All Freestanding Portable Air Conditioners Have to Be Vented Out a Window?

Yes, portable air conditioners must be vented out a window. Your other options are to vent a portable AC unit out a door, through a wall, or ceiling.

It’s necessary to vent portable air conditioners because they extract hot room air.

If you want the AC system to cool the room effectively, you need to let the hot air vent to the outside.

What’s Better Window or Portable AC?

The better option depends on your particular needs.

As for cooling capacity and efficiency, both window and portable ACs deliver similar results.

Most people choose a portable AC unit because it’s easier to install, doesn’t take up as much window space, and can be moved between rooms.

Also, the best portable AC units tend to have more advanced features, including things like smart Wi-Fi control and self-evaporative dehumidification.

Can You Use a Portable Air Conditioner in a Room with No Windows?

Yes, you can use a portable air conditioner in a room without any windows, but you’ll have to get creative with the installation.

All AC systems need to release heat somewhere and a window is the most convenient place to do it.

However, you can also vent a portable air conditioner out an exterior wall, through the ceiling, into another room through a door, or into an existing dryer vent outlet.

Do You Have to Empty Water from a Portable Air Conditioner?

In most cases, you will not have to empty water from a portable air conditioner.

Many standing air conditioner units come with self-evaporative dehumidifiers that wick moisture away as it’s pulled out of the air.

However, not all models include this top feature, so make sure to look for it when choosing a top rated portable air conditioner.

When that feature is not available, you’ll need to drain an internal water tank or connect a drain hose that sends the water to a floor drain or outside.
