Buyer’s Guide For Portable Air Conditioners
How Does a Portable Air Conditioner Work?
If there is no central AC at your home, you shouldn’t settle for window units or fans to keep you cool. Just by plugging a portable air conditioner into a standard wall outlet you can get the desirable temperatures with little effort. A portable unit looks like a mini-fridge on wheels. The controls allow setting the required temperatures and switching between cool and fan modes. Some models also come with a dehumidifying feature. Portable air conditioners function the same way as HVAC systems and window units. But unlike them, they don’t require permanent installation. Due to a small weight, they are simple to use, convenient, and can be moved around the room. Just like any other AC, this unit releases cold air and expels warm air outside. For expelling warm air, they use a large-diameter vent hose. One end of it is connected to the device and the other one gets outside through a window, door, or any other slot. When the appliance is being moved, the hose moves with it. But the most common situation is when the unit is located nearby the window and the vent hose is snaking up to it.
Similar to other air conditioners, the portable one contains coolant and consists of a compressor, condenser and evaporator. The coolant gets to the compressor as a cold gas under low-pressure. When passing through it, this gas squeezes greatly. After the compressor, the coolant enters the condenser as a hot gas under high-pressure. When passing through the condenser, it turns into a liquid. Then it comes through a narrow opening into the evaporator. As there is no more high pressure, it turns back to gas again. Thus, air cools down and can be released into the room. The gas returns to the compressor ready for the next cycle. Portable air conditioners have an internal reservoir for excessive condensation. It can be emptied through a hose into a drain or manually.
A portable unit work at its best when it located close to opening. The closer it is to the slot, the more hot air will be expelled outside. It would be useful to insulate the hose with cloth or towels to prevent it from heating the indoor space during the operation. Nowadays, portable air conditioners are widely distributed in various makes and models. So-called reversible monobloc air conditioners can even produce heat during the cold season. Moreover, some portable units have air filters. They purify air by removing dust, molds and other allergens, while making it perfect for people with respiratory diseases. It’s clear that these devices have proved to be very useful and can become an indispensable part of most homes out there. Just because a portable AC can be operated independently, it is easy to target cool air directly to the place where you are. Another benefit of operating these devices is that they use less energy than other air conditioner types.
Why Should You / Should You Not Get a Portable Air Conditioner?
If you are looking for a portable unit but don’t know whether it will match up your requirements or not, make sure to learn all pros and cons before you buy one. A portable unit is a home climate equipment that is highly demanded for several reasons. One of them is their mobility. However, there are numerous other aspects that should be taken into account when planning to purchase it. The first and foremost thing is that a portable AC uses a compressor and a refrigerant that makes it much more effective than a usual air cooler. While enabling proper cooling, a portable unit keeps the humidity at a low level.
At the same time, these appliances have some drawbacks. A few major concerns are: cooling range, improper water management, and problems with the placement. This unit can pull the moisture from the air into a tank while dehumidifying the indoor space. It creates a comfortable atmosphere and is an obvious advantage. However, this moisture needs to be discarded. Hence, a portable unit should be placed near the location that allows water to flow out through a hose (for example, near a window). Sometimes it will also have to be done manually.
The other aspect which makes a portable air conditioner less convenient is a plug-in system. Although there is no need to install this unit “permanently”, it has to be placed where you can plug it in. This aspect limits the cooling space. So, instead of being closer to you for your comfort and convenience, this AC must be closer to the electrical outlet.
Portable units with a tube are definitely less efficient in cooling the indoor space. The air that expels outside is a dehumidified air from the inner space. This results in energy wastage as the AC has to cool the air that hasn’t been dehumidified yet. The outer air that replaces the inner dehumidified air is warm and humid. It also creates an uncomfortable atmosphere. However, the latest models of portable air conditioners have two hoses and it makes them similar to window units. These two hoses send cool and warm air to different locations which is much more efficient.
Although portable units are considered to be mobile in the sense they can roll around, there may be some difficulties while actually moving them. The floor surface should be taken into account because a simple carpet on the floor or any other roughness may become an obstacle during replacing AC from one place to another. And there’s one more point that should be taken into consideration as well. Since the compressor, condenser and evaporator are located in the very same unit, these air conditioners tend to create more noise.
Then again, some people don’t realize the fact that, even though a portable unit isn’t a window AC, there still has to be a window to use it! The vent hose has to run into a window, door or any other way of venting. If you can’t get the end of tube out, a portable AC won’t be a good choice.
How to Calculate the BTU Needed for Room Size?
Shopping for a portable AC that fits a certain room size or specific needs can be quite challenging. But knowing if it meets the cooling requirements of the room is another question. In other words, size matters! When purchasing a unit that is too small, you will end up with a relatively cool room or with an appliance that overheats. On the other hand, if a unit is too large, it won’t be able to remove the moisture from the room and make the indoor air clammy. As you can see, both options are not desirable. Therefore its important to calculate BTU to pick the AC that is perfect for your needs.
A British Thermal Unit (BTU) is a measurement of how much energy is needed to heat 1 pound (0.454 kg) of water by 1 degree Fahrenheit (0.55 degrees Celsius). Each AC, including portable ones, is rated to produce a certain number of BTU’s per hour. To avoid spending extra on energy bills, it’s important to find a unit with a BTU that matches your requirements. Therefore, you should figure out how to get the required BTU output.
You can use a BTU calculator that is available on countless websites. The “reference chart” below will give you a clear understanding on how many BTU’s you will need.
BTU CHART BASED ON ROOM SIZE

By using it, you will be able to determine the correct amount of space to be cooled and pick the right model of a portable AC for the job. Then just adjust the correct capacity according to the following factors:
Reduce the capacity by 10% if the room is shaded heavily. And the opposite, if the room is sunny, increase the capacity by 10%.
If there are more than 2 people in the room regularly, add 600 BTU’s per hour for each person after the second one.
If it is a kitchen that needs to be cooled, increase the capacity by 4,000 BTU’s per hour.
Increase the capacity by 10% if you reside in a warm, humid place.
All in all, it is not a big deal to calculate it correctly.
How to Calculate the Energy Efficiency Ratio (EER)?
Energy efficiency is a “hot” topic these days, and for good reasons as an energy efficient product will be good for your wallet as well as for the environment. Portable AC’s can be categorized by their EER or energy efficiency ratio. The EER is very simple to calculate and all you have to do is to divide the portable air conditioner’s BTU by the wattage consumed.
Example: A 14000 BTU portable air conditioner consumes 1500 watts, so its EER-rating will be 9.33 (14000 divided by 1500). As you’ve probably figured out yourself already, the higher the rating (EER), the more energy efficient the AC will be.
Generally, an EER-ratio of 11 is considered to be high for portable air conditioners. Our top pick, the Whynter Arc 14-S has an EER of 11.2, which makes it one of the most energy efficient units on the market.
What Features to Look for in a Portable Air Conditioner?
Most models of portable air conditioners offer various features that are not only handy and enhance your cooling experience but also help keep your home cooled more efficiently and save money in the long run. The most common of them are the following:
Programmable timer and sleep settings
Odor removal and air purification
Adjustable air vents
Here is a brief review of the basic features:
Programmable timer and sleep settings
A programmable thermostat allows presetting your unit to switch on and off at a time that is suitable for you. Thus, you will be able to make some savings on time and money by operating it wisely.
Some models allow setting a precise temperature. Once it’s been reached, the machine turns off. Or it turns on and starts cooling at pre-programmed times. Many portable units even offer such function as sleep settings. When on, it will maintain comfortable temperatures in your room quietly and intelligently.
Just like regular split-systems, some portable units can operate in reverse-cycle. It means they can cool your room during the hot season and heat your home during the cold one.
The self-evaporator technology allows evaporating humidity and moisture collected from your room and exhausting it through the hose. Therefore, you won’t have to empty the container with collected water every few hours.
Some units comes with a dehumidifer feature. Excessive vapor and humidity makes indoor air stuffy and frowsy. It can also cause the growth of mold and mildew. When the dehumidifying feature is on, it removes moisture and dampness from the air and makes the indoor environment more comfortable. This feature is of a great importance for those who suffer from allergies and respiratory conditions.
Odor removal and air purification
When it comes to odor removal, this feature can be helpful in removing cigarette smoke, smell of mildew, and other unpleasant odors.
An air purifier uses a filtration system to remove such harmful pollutants as dust, pet hair, bacteria, and other debris. It creates a healthier and cleaner environment that especially matters to people with allergies, respiratory issues and other sensitivities. For the best air cleaning, you should look for an appliance with HEPA filter system. The HEPA filter removes dust, pollen and dander to name a few. As a result you will get a cooled air that is significantly easier to breathe as well. Oftentimes, it’s possible to notice the control of allergy symptoms as the most common triggers are being caught in the HEPA filter.
Remote control can be useful if your portable AC is located in the place that is hard to reach. Some units use remote controls only which are usually available in hand-held styles.
Adjustable air vents
Adjustable air vents are designed to shift the air flow. This feature works similar to a car’s AC. Surprisingly, not all portable units have it on-board. Some models have air nozzles that can be extended or rotated to direct the air flow directly where you need it.
Additional modes that are also available in portable AC’s of various brands are:
