Central air conditioners have been the go-to solution for many homeowners in the US. However, portable air conditioners are gradually proving their worth and becoming a consumer favorite. While they may not possess the efficiency of a window unit, they provide more comfort than a fan. Portable air conditioners are not as expensive to operate as central air-con units, and their portability offers flexibility and convenience for the changing seasons.

Why Go Small?

At an average weight of 50-80 pounds, portability is hardly the best defining trait of the average portable air conditioner. Setting up such an appliance takes up time and effort; couple that with its weight, most portable AC’s remain stationary.

So, why go small? Apart from saving up floor space, smaller units are more efficient in their performance. According to the US Department of Energy, a room air con, too big for the area it should cool will be less efficient than a smaller, suitably sized unit. This is because the oversize unit cools the room to the set-point of the thermostat before the onset of dehumidification, creating a clammy, uncomfortable feeling.

Therefore, ideally, you want to get the smallest portable AC that will effortlessly cool your room without using excessive energy. However, the size of your appliance is contingent on the size of your room, since some smaller units may be unable to cool a more extensive room effectively.

The perks of a smaller portable AC include:

More efficient at cooling bedrooms among other small spaces
Less floor space and weight
Quieter than large AC’s
Easier storage when not in use

If your house has constricted space, or want to cool a small area of it, a small portable AC is an ideal choice.

6 Factors to Consider

Here are six factors you should consider when looking for your ideal air conditioner.

Unit Size

Most portable AC appliances fall under the same size range (height; 25” to 35”, depth and width; 12” to 18” and weight; 45 to 95 pounds). Therefore, in your quest, it is crucial to determine if you want the shortest, narrowest or lightest unit. Consider this; while someone living in a room with constricted space prefers a unit that consumes the least space, someone in a larger house may be worried by its height or weight.

It is crucial to remember that although portability may seem like a vital consideration, once you find the appropriate spot for your appliance, you may not move it much.

Cooling Power

The unit of measurement for cooling power for portable ACs is BTUs (British Thermal Units). For air conditioners, a BTU is the amount of energy required to remove heat from the air. A general rule of thumb to determine how many BTUs you need for your room; 20 BTU for one square foot. However, the Department of Energy adds that other conditions such as room height, climate, window size, and shading may significantly affect the AC’s cooling capacity.

It is always tempting to opt for something with more BTUs even for small rooms. However, remember that matching your room size with the appropriate cooling performance will enhance efficiency, and performance as well.

Energy Efficiency

It stands to reason that smaller AC appliances are more energy efficient because they use less energy to cool the living space. This efficiency is measured by a unit known as the energy efficiency ratio (EER). EER can be described as the cooling power equated to the wattage required to operate the unit.

The higher the EER rating, the higher the energy efficiency. When buying, you can identify an efficient AC with a label from ENERGY STAR, as they’ve met the extra requirements set by the government.

Energy Star Savings Table Air Conditioners

Noise Level

Unlike the noise that comes from the central AC, and large AC units, the sound from small portable ACs is significantly quiet. However, if white noise may distract you in any of your endeavors, this is a crucial consideration.

The noise range for most units lies between 50 and 80 dB and is expected that the manufacturer provides these readings. However, like BTUs, these values may not be as advertised. A unit’s noise level may determine the room in which it is used. For instance, a light sleeper may avoid having a noisy appliance in their bedroom, and still use the same AC for their home office.

Extra Features

While all of the units we’ve reviewed will do the job, some of them provide additional features, of which you may want to be aware. A remote control unit is convenient, as is an AC that also doubles as a heater, meaning that you won’t stop using it during colder seasons.

The LG LP0817WSR has an auto-swing ventilation mechanism that reduces hot spots, and warm areas in the living space. Such features enhance air circulation, ensuring that the air is cool and fresh. How about a model with self-evaporating features? This means that you don’t have to empty the tank. There are also features that prevent an AC unit from over delivering cool air after the intended temperature range is achieved.

A comparison between your best picks can help you determine the extra features you need. For instance, if your house has a reliable heating system, you may not require the unit that also serves as a heater.

Warranty and Support

Most of the small portable ACs you will come across are from renowned manufacturers, offering various customer service and support options. Most of the models we researched have a warranty period ranging from one to five years. While some of these guarantees provide full coverage, others offer limited warranty to cover particular issues and parts.

A Gradual Guide to Purchasing a Portable AC

Portable ACs, also known as PACs are excellent solutions for cooling spaces that aren’t large enough to accommodate a window-mounted version. Purchasing one of these appliances may be slightly daunting without any experience, don’t worry, this guide will give you a head start for when you go PAC shopping.

How Much Power Do You Need

Power is a crucial consideration when deciding on the PAC to purchase; an under-powered unit will not give you the desired result, especially during hot, humid weather, and an overpowered unit may prove difficult establishing a comfortable setting, or rack up more operational costs.

The amount of power required is contingent on the square footage of the space you want to cool. Professionals also indorse taking into account the floor plan and insulation plan of the target room for a more suitable BTU rating. Failing to consider the insulation and other variables like ventilation may expose your room to excess condensation.

Another substantial concern when considering the proper BTU rating is whether the said unit is a single or dual-hose Portable AC. Ideally, the dual hose is more energy efficient than single-hose portable air conditioners. BTU guidelines may vary with the AC’s manufacturer. Therefore, always round off the values slightly to the conservative side.

Consider Environmental Factors

The performance of your portable AC can be affected by environmental factors as well. Sunlight is a crucial factor, especially in the afternoon. For instance, if your room gets covered by heavy shade, you may need to reduce your BTU capacity by 10% and increase it similarly if it receives direct sunlight.

The number of people occupying the room is another aspect. For every additional person exceeding two in the room, you should add 600 BTU to account for the body heat and the CO2 produced which contributes to the room’s warmth.

Decide On the Controls

Depending on your preference, you can opt for portable air conditioners with manual or remote controls. Most modern PACs you find contain smart features that will either save you energy or add to the convenience. Some models can restart at your preferred settings, while others may have a timer to dictate when you need the cooling to begin, and when to stop.

Remember that the more you prefer regarding convenience, you will compensate in price.

Other Factors to Consider

All the factors mentioned above considered, it is paramount to ponder about the long-term. The duration you are planning to leave your unit on, and the customer support provided by the manufacturer should be among such factors. For instance, if you live in a warmer locale, and will run it for most of the year, you cannot withhold on durability, as opposed to needing the unit only for the summer.

The level of noise is another relevant point to contemplate. Are you installing the portable AC in the nursery, bedroom, or office? If you are a light sleeper, you do not want to get stuck with an appliance that makes too much noise in the bedroom.

Here’s a pro tip: A model with several fan settings will allow you to create the perfect balance between power and noise.
