What It Does
A portable air conditioner works by sucking up hot air from a room and transporting it outside through the exhaust hose.
The unit pulls moisture from the air as well, decreasing humidity and temperature. This is done through the use of coils, compressors, refrigerants, and fans working together.
The fan inside the unit draws in hot air from the room, which is then cooled by the refrigerant inside the condenser coils. This process also pulls moisture from the air.

Cool air flows back into the room, while heat and water vapor are transported out the back of the unit via the exhaust hose. This process can create negative pressure inside the room, making air drawn in through leaks.
A dual hose portable air conditioner avoids this issue by drawing in air from outside to internally cool the unit. This makes the dual hose system more efficient.

Why Choose?
Portable air conditioners are the way to go if you want convenience and ease of setup. They're perfect for small spaces that don't need air conditioning all the time.
If you don't have compatible windows, portable air conditioners are a great option. They can be used in a variety of window openings, making them more versatile than window units.
Portable air conditioners are ideal for apartments or homes with unique fixtures. They're just one machine that can cool your entire space.
Energy Efficiency and Performance
Energy efficiency is a top concern when it comes to portable AC units. Look for Energy Star certification, which is a good indicator of a unit's energy efficiency.
The CEER, EER, and SEER numbers are also important to consider. A CEER above 10 is a good starting point, and anything above 12 qualifies for Energy Star certification.
To give you a better idea, a SEER above 14 in the north and 15 in the south is a good target. Similarly, an EER above 10 is also a good benchmark.
One thing to keep in mind is that even with an energy-efficient unit, leakage can still be a problem. Insulating the hose and exhaust port can help minimize this issue.
You can use foam pieces provided by the manufacturer to insulate the window opening, and you can also buy or make your own insulation for the hose.

Comparison and Cost
Window ACs are usually the least expensive option to install and are often the easiest to set up. Portable units are a close second in terms of affordability.
Ductless mini-splits, on the other hand, tend to be pricier due to the additional components and more involved installation process.
Cost vs Ductless AC Systems
Window ACs are usually the least expensive and easiest option to install. They're a great choice for small spaces or rooms without existing ductwork.
Portable AC units come in at a close second in terms of cost. They're a flexible option that can be moved from room to room.
In contrast, ductless mini-splits tend to be the pricier option. This is because they require additional components and a more involved installation process.
However, ductless units are much more affordable than upgrading to central air conditioning. They allow you to avoid installing ductwork where none currently exists, which can save you a lot of money.

Comparing 'Different' and 'Than'
Window AC units are small, packaged air conditioners that fit in your window and cool one room at a time.
Ductless AC units are far more convenient if you want to enjoy a fresh outdoor breeze, as they don't use the window.
A window AC unit is essentially a stationary appliance that remains in place all summer long due to its weight.

Portable AC units, on the other hand, can be a bit more flexible, but you'll need to remove the hose from the window to let a breeze in.
Both window and portable AC units require occasional maintenance, such as emptying a condensate pan as they collect humidity from the air.
The main difference between a window AC unit and a portable AC unit is where the hot air exhaust is located - one is in the window, and the other is on the floor.
How We Tested
We placed each unit in its own room to isolate their performance and directed their discharge hose to the outside. We set the appliance's temperature to 68 degrees and its fan speed to maximum to simulate real-world conditions.
We used an infrared thermometer to measure the temperature at four different locations on the target, 8 feet away from each unit. This gave us a clear picture of their cooling effectiveness.

To test the wheels' durability and noise, we rolled each unit on a hard surface to maximize squeaks and rattles. This helped us identify any potential issues with their mobility.
We also checked the appliance's outlet to see if it maintained a consistent temperature, which is crucial for reliable performance.
Design and Convenience
Ductless air conditioners are far more convenient than window and portable AC units when it comes to enjoying a fresh outdoor breeze. They don't require a window to operate, so you can open your windows and let in the fresh air whenever you want.
Window units, on the other hand, can be a real hassle to move or remove, weighing you down with their cumbersome presence all summer long.
GE Profile
The GE Profile Portable Air Conditioner is a game-changer for anyone looking for a convenient and effective cooling solution. It's incredibly quiet, with a noise level of just 42 decibels in quiet mode.

This unit is designed to be compact and unobtrusive, making it perfect for small rooms or overnight use. The dual-hose design increases airflow, allowing it to cool a room of up to 450 square feet in under 10 minutes.
One of the standout features of the GE Profile is its auto louvers, which help distribute cold air evenly throughout the room. This is especially useful in rooms with high ceilings, where hot air can accumulate.
The unit's modes include cool, fan, and dry, and it also comes with a remote control. However, it's worth noting that the remote control buttons don't light up, so you may need a flashlight or other light source to use it in the dark.
Here are the key specs for the GE Profile Portable Air Conditioner:
Coverage Area
Manufacturers provide the number of square feet a given unit can cool, assuming average ceiling height (roughly eight feet).
To gauge coverage, figure roughly 20 BTU per square foot of space. Most portable a/c units range from 5,000 to 20,000 BTUs.
If the room is especially hot in the summer, we recommend moving up to the next size.
Hose Length

Hose length is a crucial factor to consider when setting up your portable air conditioner. Most hoses range from 50 to 90 inches fully extended, giving you enough space to make adjustments.
If you set up your air conditioner in a large room, hose length becomes even more important. You'll want to ensure the hose can reach the nearest window without any issues.
In some cases, you may need to rearrange the room to accommodate the air conditioner's placement. This is especially true if the hose isn't long enough to set the air conditioner in front of large furniture pieces.

Convenience of Units vs. AC Units
Ductless AC units offer more convenience than window and portable units when it comes to enjoying a fresh outdoor breeze.
You can't open your windows with a window unit installed, as it's too heavy to move. Portable air conditioners also require you to remove the hose from the window to let in a breeze.
Ductless AC units are a game-changer for people who love having their windows open.
Their design allows you to enjoy the view and a pleasant breeze whenever you want, without the hassle of removing hoses or moving heavy units.
In contrast, window and portable units can be cumbersome and inconvenient, especially if you want to let in some fresh air.
Functionality and Options
Window and portable AC units tend to operate quite loudly.
They are also restricted to air conditioning only, so you'll need another system to meet your heating needs.
Ductless mini-splits are miniature heat pumps that can heat and cool your home, offering year-round comfort.
They often come with convenient features like wireless remotes, timers, and multiple fan settings.
While ductless ACs may cost a little more upfront, their performance, appearance, and convenience make the higher price tag well worth it.
