A portable air conditioner is a free standing air conditioner or stand alone unit that needs to be vented through a window. These units are self-contained and operate the same way as window and wall air conditioners by pulling cold air into the room, removing the heat, dehumidifying the air and exhausting the hot air out through the window vent.
Like other air conditioning units, they also remove moisture from the air but do it to a greater extent than other air conditioners since most of these units have a dehumidify mode.
What Are the Benefits of a Portable Air Conditioner?
The convenience of these units is that they have wheels and can be moved from room to room depending on where you need them most. Since they need to be vented, you have to replace the vent kit too whenever you move the unit.
They can also vent them through sliding patio doors or sliding windows. They can be vented through a ceiling or a wall, but you would need a contractor for that, and it takes away the portability of the unit.
Another pro is that they usually have three different modes, fan, air conditioner and dehumidify. The fan is good when you just need to circulate the air a bit, the air conditioner when it’s too warm and just needs a little dehumidification, and the dehumidify mode when it is very humid out. As with other air conditioners, the tray or pan will not need to be emptied when in air conditioning mode because it self-evaporates. When it’s in dehumidify mode the tray needs to be emptied. The unit shuts itself down when the tray needs to be emptied, and a warning light comes on.
You can also get a portable air conditioner with heat mode if you need a supplemental heat source. You need to look specifically for that feature since most of them do not come with that function. Units with heat can be slightly more expensive. Portable air conditioners are more expensive than regular air conditioners.
What are the Cons of a Portable Air Conditioner?
When using dehumidify mode, the pan or tray at the bottom of the unit will need to be emptied on a regular basis. The unit turns itself off when the tray is full. You can buy a drain kit separately since not all units come with them.You will have to check with the manufacturer for the size of the drain before you purchase the kit.
The hose with the drain kit can be run to a sink or tub, or you can use a large bucket. You will still need to keep an eye on and empty the bucket, but it will prevent the unit from shutting itself down as often since the bucket is larger than its tray.
If your living area is on one floor and you don’t mind moving the ventilation kit from room to room as you need it, then these units will be right for you. These units are not quite as portable as you might think if you have to move the unit up and down the stairs. Portable air conditioners are quite heavy, weighing between 60 to 80 pounds, and you would need help to do it.
A portable air conditioner is not as powerful or energy efficient as the other types of air conditioners. They do not qualify for energy star ratings. While it is generally not recommended to buy more BTUs than needed when it comes to a window or through the wall air conditioners, you will need to do that when it comes to a portable air conditioner since they are not as reliable for cooling evenly as regular air conditioners.
Portable air conditioners only work at about 60% of the capacity of traditional air conditioners. If you think you can replace a window or through the wall air conditioner with the same amount of BTUs you will be disappointed. It will take many more BTUs to cool the same space that a window air conditioner would.

This type of air conditioner is best used when a window or through the wall air conditioner are not an option. These units are not as quiet as other air conditioners, so if it is going to be in your bedroom, it might take some getting used to.
What is the Difference Between a Single Hose and Dual Hose Portable Air Conditioner?
Single-Hose Portable Air Conditioners vent hot air out through a single exhaust hose that connects to the back of the unit.
Dual-Hose Portable Air Conditioners have two hoses attached to the back of the unit: one hose vents out warm air while the other hose draws in additional air to be cooled.
Dual hose units are more powerful and will cool or dehumidify more quickly. Single hose units are quicker and easier to install.
When using the dehumidify mode, some dual hose units require that you temporarily disconnect the cold air hose and reconnect it when you are done dehumidifying.
How Do You Choose a Portable Air Conditioner?
- The BTUs. The size of the area you will be cooling is the most important factor. The width and length of the room are necessary to figure out the correct amount of BTUs that you need. As stated earlier, portable air conditioners are not that energy efficient so in this case, it would be best to get a unit that has slightly more BTUs than you actually need for the space you will be using it in.
- The Energy Efficiency Rating or EER. All air conditioners have an energy efficiency ratings, so try to get one of these units with as high an energy efficiency rating that you can. Portable air conditioners are not energy efficient enough to earn energy star ratings.
- You should take into consideration the amount of sunlight that the area you will be cooling gets. If it’s very sunny, you need to add about 10% more BTUs. The BTUs should also be increased by about 500 BTUs per person over and above two individuals who inhabit the room or area you are using it in.
- The Purpose You are Using it For.When it comes to portable air conditioners since they do not work as well as other types of air conditioners, the purpose for which you will use it is important. Many people use them as supplemental sources for cooling and not the primary source. Some people use them as additional sources of heat. Like me, some people use them to dehumidify both in the air conditioning mode and dehumidify mode.
- Placement is important when it comes to a portable air conditioner. These units are quite bulky and need about 18 to 20 inches on all sides to function properly. You need to make sure you can give up that amount of space if you will be buying this type of air conditioner.
Which Portable Air Conditioner Should You Buy?
When it comes to portable air conditioners, you have many different options. I’m going to show you five of the most popular ones by one the top manufacturers for you to consider.
Remember that these units are more expensive than window air conditioners and that you need to size up to cool the same size room that you would for a conventional window air conditioner. The room size recommendations below are from the manufacturer.
If you have been browsing around the internet for a portable air conditioner, you might notice that some websites say these same units can cool larger rooms. Those sites might be paying attention to the BTU chart and not the manufacturer. All of these portable air conditioners are single hose units and use an 115V grounded outlet (regular household outlet).

How Do You Install A Portable Air Conditioner?
Portable Air conditioners are relatively easy to install. They come with one or two exhaust hoses that are about three to five inches in diameter and attach to the back of the portable air conditioner unit to a four or five-inch PVC piece that sits on the window sill or ledge and the bottom of window closes on top of it similar to a window air conditioner.
It does not obstruct the view as much as a window air conditioner does since the PVC piece which sits in the window is only three to five inches tall.
Some units come with pieces of foam weather stripping to stop drafts. I prefer to use clear weatherproof tape since I use my portable air conditioner in my basement mostly to dehumidify since I live near the ocean and a bay and do not intend to move it from room to room.
Most portable air conditioners use a regular 3 prong household outlet although some state that a GFCI outlet would be preferable, depending on which room you are using it in. GFCI stands for Ground Fault Circuit Interrupter, it is an outlet that can prevent an electrical shock in wet locations.
A GFCI outlet has two buttons: a test button and a reset button. If you are replacing one of these units be sure to check the plug on the new one you will be purchasing so that it matches your outlet. I have mine plugged into one of these types of outlets because my basement has flooded when there has been excessive rain.
Below is a video by LG showing how to install a portable air conditioner.
Tips for Using and Maintaining Your Portable Air Conditioner
Since portable air conditioners are not as powerful as other types, take advantage of the timer feature and start the unit a couple of hours before you need it. If you are using it in an enclosed space, keep the door closed so you get the optimum amount of cooling power.
Keep the unit as close to the ventilation source as possible while still maintaining the proper amount of space needed around the unit. These units work much more efficiently when the hoses are shorter and not fully extended. Make sure the hose is straight and not kinked up to maintain the best air flow and to keep moisture from the exhaust out of the unit.
If possible try to keep the unit out of direct sunlight. The air conditioner has to work harder if it gets too hot. Use an oscillating fan or a ceiling fan to help distribute the cold air more quickly since these units are not as energy efficient as regular air conditioners.
Clean the filter on a regular basis. Most of these units come with a reusable filter that you wash and put right back in after drying it. I clean mine weekly. Check your owners manual to see what they recommend and whether or not your filter is reusable. Some units also come with a second carbon or antimicrobial filter. Check your manual to see if that needs to be cleaned or needs to be replaced.
Clean the outside of the unit too with some warm water and a paper towel. Make sure any vents are clean and free of dust and dirt. Use the soft brush attachment of the vacuum to clean deeper into the vents once you clean away any surface dust Proper maintenance can go a long way to extending the life of your portable air conditioner. If you take care of the unit, it should last you a long time.
I recently purchased a new portable air conditioner, but my previous one lasted over 10 years. The air conditioner and fan still worked perfectly but dehumidify mode, which is my primary purpose for the unit stopped working. Otherwise, I wouldn’t have needed to replace it.
If you cannot have a window or through the wall air conditioner a portable air conditioner might be just what you need. As long as you are prepared to buy more BTU’s than the room size calls for then the unit should do what you need it to do.
Due to the wheels, moving the unit from room to room as long as the room is on the same floor should not be a problem. As long as there is a window available to vent it through the unit will work just fine.
I happen to love my portable air conditioner. I use it in air conditioning mode to handle the humidity in the spring, which is moderate, and I use it strictly to dehumidify in the summer when the humidity is much worse.
It does exactly what I need it to do. Unlike stand-alone dehumidifiers, portable air conditioners actually throw off cold air in dehumidify mode so my basement stays comfortable. I love the fact that I can walk in my front door and no longer smell a damp musty basement.
If you rent an apartment or a home or live in a place where air conditioners that protrude from your home are not allowed, and you like the convenience of being able to move it from room to room, then a portable air conditioner might just fit your needs perfectly.
