Why It’s Smart To Go Small
Driven by innovation and a growing commercial and household segment, the demand for portable air conditioning units across the world is expanding. Market research specialist Acumen Research and Consulting, for instance, estimates the global market for portable air conditioning appliances to reach around US$1.7 billion by 2025, for a CAGR of 11% in the 2018-2025 period.
A growing number of consumers can’t be wrong. Indeed, the ever-increasing interest in compact air conditioning units is understandable. Some reasons for choosing a small-sized ac over its bigger counterparts or window-type units are quite apparent as we’ve pointed out below.
- Mobility
- Easy installation
- Occupies less space in the room
- Easy storage when not in use
Consumers, however, choose small room air conditioning units for more compelling reasons.
Energy efficiency
The US Energy Department states that using an ac unit too large for the intended room will result in less efficient cooling performance. This is because the AC will likely cool the room to the desired temperature even before the proper humidification has been achieved, thus, leaving an uncomfortable clammy feeling in the room.
In addition to this, low-watt units are more energy efficient as they can be used to cool particular rooms without the need to turn on the central unit or they can supplement the central unit in areas where cooling is still needed.
Innovation
Another attraction of small space air conditioners is the exponential development in innovation. With constant investments spent by manufacturers on R&D, the market has come up with more and more features that increase the benefits of using small ac units.
Our product reviews earlier showcased units that feature dual motor technology that cuts noise during operation. Moreover, dual-hose exhaust technology provides 40% faster cooling while some models can run for only a dollar a day. For convenience, some portable ac brands have also incorporated sensors into the remote control to make the portable ac unit automatically adjust its thermostat settings depending on where the user is located in the room.
Factors To Consider When Choosing the Smallest Portable Air Conditioner
The growing number of air conditioner brands available to consumers has made purchasing a unit more challenging. Since air conditioners for small enclosures come in all shapes and sizes with varying capabilities and features, narrowing down your choices and finally deciding on the best one has become far more challenging.
Here, we outline the crucial factors you need to consider.
Brand
While most reviews do not include a discussion on brand, we feel that it is a crucial factor to consider when buying a portable ac. This is because the units are only as good as the manufacturers behind them. The brand is the culmination of all the years of experience, passion, and R&D the manufacturers have put into their products.
For that reason, companies with plenty of experience and a solid reputation are likely to create a reliable and innovative range of products.
In this same light, a company that focuses solely on making portable air conditioning units are most likely to know more about this vertical than those manufacturing a complete range of consumer products.
This, however, is not always the case as companies who have years of experience making a full product range also benefit from the synergies in know-how created by having R&D across different product groups.
Checking out the brand at the onset, therefore, can help you narrow down your choices to only a few manufacturers that have built a reputation.
Indeed, if you look at the customer reviews, you will notice that manufacturers that have ample experience and resources to invest in R&D activities are those that are most likely getting the positive feedback from consumers.
Brand name doesn’t mean the AC must be expensive. In fact, we have reviewed some portable air conditioners under $200 from very reputable companies.
Functionality
You also need to consider the features you prefer your portable air conditioner needs to have. While most units come with a dehumidifying function on top of the standard cooling and fan features, only a few of the larger ACs come with a dedicated heat pump. It is wise to determine early on if you need a cooling unit or a 4-in-1 appliance you can use the whole year round.
Cooling Power
The ac unit you need will also depend on the size of the room you want to cool. An AC that is too small for the space you want to cool will be money down the drain as you won’t be able to achieve the expected results.
The cooling capacity of an ac unit is measured in BTUs (British Thermal Unit). It is a measurement of an HVAC system’s cooling or heating capacity and is used to calculate the amount of energy a unit can deliver.
One BTU is equal to the amount of energy used to raise the temperature of one pound of water by one degree Fahrenheit. The higher the BTU number, the more heat the unit can produce.
Air conditioners are a little bit different. The BTU number on a cooling appliance refers to the amount of energy used to remove the heat from the air. The larger your room is, the higher the BTU you will need.
Once you have determined the size of the space you need to cool, you can then multiply this figure by 20 to get the bare minimum BTUs you need. Let’s say you’re buying a portable air conditioning unit for a 400-sq.-ft. room, then you’ll need at least 8,000 BTUs. That is, 400 sq. ft. multiplied by 20.
It is important to note, however, that you need to consider other factors besides room size in determining the BTU you need. This is because the cooling capacity you require will also depend on several other factors such as:
- The type and quality of insulation in your room, the type and size of your windows, height of your ceilings and location of your room.
- If the room is located in a sunny place, you need to adjust your BTU requirement by about 10%, according to Energy Star.
- If more than two people regularly occupy the room, you have to add 600 BTUs for each additional person.
- The government agency also advises to increase the cooling capacity of the cooling unit you want to buy by about 4,000 BTUs if you plan on installing it near the kitchen.
Missing out on these necessary adjustments when determining the right BTUs could lead you into buying a unit that’s not capable of delivering the cooling comfort you need.
Energy Efficiency
Another crucial factor to consider is the unit’s energy efficiency, which is measured by the Energy Efficiency Ratio (EER). It is computed as the cooling power in BTU divided by the amount of electricity the unit consumes.
A 10,000 BTU air conditioner that requires 1,200 watts of energy to operate has an EER of 8.3 (10,000 BTU divided by 1,200 watts). The higher the EER, the more energy efficient the unit is.
The EER can come in handy when you have to decide between two units with the same BTU cooling capacity and features.
Let’s say you have to pick between two ACs both at 10,000 BTU. One consumes 1,200 watts while the other requires 800 watts to operates. Computations would show while the first unit would have an EER of 8.3, the second unit would be more energy efficient at an EER rating of 12.5.
To ensure that you pick the most energy-efficient portable air conditioning unit, see to it that you choose one that is Energy Star rated. This means that the appliance meets the government’s requirements for energy efficiency and environmental protection.
Noise Level
The noise produced by a portable air conditioner is another factor to consider given several circumstances. If you are a light sleeper or intend on using the unit in a very quiet place, like the bedroom, then this factor may be an important thing to look into.
Measured in weighted decibels (dBA), the sound produced by a portable ac unit can range from less than 50 to 80 dBA. What does this mean? A measurement of 40 dBA is equal to murmurs inside a library, while 60 dBA is similar to the sound made by conversations inside a restaurant.
Keep in mind that most of the air conditioners are louder than the advertised noise level. It would be wise to also read through the product reviews regarding the noise the products make instead on solely relying on the information indicated in the product specifications. We reviewed some of the quietest portable air conditioners by Decibel rating.
Warranty and Support
Since all air conditioners require maintenance, you need to consider the type of warranty the unit carries. The good news is most reputable manufacturers offer various customer service and support options.
Most of the models we’ve reviewed, for instance, have a warranty period spanning one to five years. While some provide full coverage, others offer limited warranty to cover only specific issues and components.
Extra Features
Once the above factors are sorted out and still left with a few products on your list to choose from, you might want to check for some extra features. A few products showcase some fresh innovative features.
These include a programmable timer that can be pre-set to match your sleeping pattern throughout the night. Some brands have also incorporated a sensor in the remote control allowing the unit to adjust its thermostat automatically depending on how far you are from it.
Other new innovations include an indicator that lights up when you need to remove and clean the washable filter. This ensures that unit always provides the best performance in terms of cooling efficiency and hygiene.
Some ACs come with an anti-freeze function, water-full indicator, restoration of settings after a power restart and a “Max” mode that sets the unit to the highest setting for quick comfort.
Features of a Good Small Portable Air Conditioner for Room
When shopping for a portable air conditioner, it’s wise to check if it has unique features that would either improve efficiency or user experience. We have listed some of these features below.
- Dehumidifier
- Automatic restart after power outage
- Washable filter
- Automatic water evaporation system
- A noise level of less than 55dBA
- LED display
- Full-function remote
- Sleep function
- 24-hour timer
- Caster wheels
- Complete installation kit
Some features are so innovative that they deserve to be noted.
Single Vs Dual-Hose System
The primary function of an AC is to cool the air in the room. During the cooling process, moisture is also removed from the air. The unit collects the condensation and drains it using a hose.
Depending on the model you have, the hose may empty this water into a bucket, or expel it to the outside using a window exhaust. Some units are self-evaporating, so the hot air exhaust is used to evaporate the water that is collected.
Some portable air conditioners are equipped with two air hoses: one that pulls air into the unit and one that removes hot air from the room.
These AC are what are known as dual hose portable air conditioners. It’s always a good idea to choose dual-hose portable air conditioners because they provide up to 40% faster cooling and greater energy efficiency than single-hose units. However, the cost may be higher due to increased efficiency.

Installing a Small Portable Air Conditioner for Room
Now that you have bought and have your portable ac delivered, the final step is to install it. This should be the least of your worries since mini air conditioners are easy to install and comes with complete window adapter kits.
You would first need to decide on the ideal location for the unit.
- It should be a place in the room that is both near the window and an electric outlet.
- The portable air conditioner should also be placed on a firm floor to minimize noise and vibration.
- For safe and secure positioning, place the unit on a smooth, level floor strong enough to support it.
- Ensure also that there will be no obstacles around the air inlet or outlet and allow at least 12” of space from the wall with the window for efficient air conditioning.
- The unit must also be placed in a location with low foot traffic to prevent people from knocking over it.
- Also avoid placing the portable ac near a fire source, flammable liquids and where water can be projected.
To install the window kit that comes with the unit, you would most likely need the following tools.
- Screwdrivers
- Tape measure or ruler
- Knife or scissors
- Saw (If the window kit needs to be shortened in case the window is too narrow for direct installation)
- Duct tape or sealant
Here are the necessary steps to follow when installing a portable air conditioner.
- Attach the window adapter kit to the window sash and adjust the length of the window kit according to the width of the window. Shorten the window kit if the width of the window is narrower than the kit. In case the window kit is shorter than the window width, you can augment the kit using Plexiglas or any hard flat material. Close the window securely against the window kit.
- If you have Andersen crank out windows, or the ones that swing outwards to open, you can take the hose attachments to a local glass shop together with one of the Andersen window screens to use as a template. The shop can then fabricate a polycarbonate window of the same size. To install the exhaust hose, remove the screen and insert the polycarbonate window and hook the portable ac to it.
- Using the hose connectors that come with the unit, attach one end of the hose to the opening in the window kit and the other end to the back of the AC. Make sure that the hose is not bent as this may block airflow and cause the unit to malfunction.
- Apply sealant or duct tape to plug any holes in the window kit.
Before finally turning on the unit, it would be wise to go through the following safety checklist
- Go over the user’s manual to see how long you need to let the refrigerant settle before turning on the unit for the first time.
- Do not operate the unit with a damaged plug or loose wall outlet.
- Do not use an extension cord. If you have to, consult a registered electrician.
- Do not place objects on the unit or sit on it.
- Do not pinch the wire in the door or pull it along edges or sharp corners.
