Portable Air Conditioners Buyer’s Guide

Finding the best portable air conditioner according to your own preferences might sound easy, but it can take a long time and a lot of careful searching to get right. No two portable ACs are going to be completely identical, and there is no point in settling for portable ACs that aren’t going to be the best portable air conditioner you could get for yourself. Air conditioning’s main purpose is to ensure that you are comfortable, so buying one that doesn’t live up to your standards can easily lead to you being stuck in an uncomfortable house with an AC that doesn’t do its job properly.

Thankfully, there are a few easy ways to speed up your search for the best portable air conditioners on the market, and one of the quickest is to put together an understanding of what you actually need. Having an idea of the best or most important features you will want can make it really easy to filter out any portable ACs that don’t fit that niche, and it can also help you avoid making a purchase that you will come to regret.

BTU

BTU, or British Thermal Units, is a measurement of how fast something can heat up water under specific circumstances. A portable air conditioner with a rating of 14,000 BTU is more effective than an otherwise identical one with only 12,000 BTU since it can create and manage more heat while also supporting a larger room size. For example, say you have a room that is 700 square feet in size: you will want around 14,000 BTU to heat or cool it efficiently. While a 12,000 BTU central air conditioning unit will still work, it won’t provide the same speed or consistency.

Make sure you don’t overlook BTU but try not to focus on it over everything else. Higher BTU ratings make it easier for a unit to keep a larger room cool, but it also means that smaller rooms can become too cool if there isn’t a way to easily lower the cooling rate. Choosing a 14,000 BTU portable air conditioner for a room that is only 300 square feet is essentially giving you twice the amount of cool air that you need. It also varies depending on your preferences: some people like to be cooler or warmer than average, so they will want to choose a slightly different BTU rating accordingly.

Remember that the natural heat of a room also plays a part here. Your BTU isn’t the only thing that affects how portable air conditioners work, so a room with a lot of sunlight will be naturally hotter than one without it.

Size

While all portable air conditioners are going to be easy to handle in one way or another, some will still be smaller than others. Portable units may earn a stereotype of being weak and sacrificing power for size, but that isn’t always the case: in fact, come of the best portable air conditioners can even surpass central air conditioning units if they are used correctly.

The real reason that the size of portable units might matter is the way that they have to be mounted or placed in certain areas. Unlike central air systems, portable air conditioners can be placed in a variety of locations and moved from room to room as needed: this is one of their main strengths, after all. Being able to pack a 12,000 BTU system into a small, portable air conditioner body gives you the ability to make any room cool just by taking it there yourself. Even if you are only using the unit in one room, you can still move it around as needed, usually without having to buy or find any extra tools.

For example, you might find that the best place for your unit is on top of a certain piece of furniture, on top of a window ledge, against a certain wall, or even just in the corner of the room. The smaller the design, the easier it becomes to fit it into small spaces.

Dehumidifiers

A built-in dehumidifier is an integral part of many of the best portable ACs on the market, giving you a quick way to remove moisture and excess water from the air for added comfort. Not only does this help you deal with humid weather more effectively, but it can make a big difference in climates where humidity is high, and there isn’t an easy way to stop your home from getting humid and full of moisture.

Dehumidifiers can work in two ways: they will either suck the moisture out of the air and deposit it into a removable tank that you have to empty or into a hose system that you can run out of the window (or into a drain, if you prefer) to dispose of it. Either of these is a valid way of using them, so it is entirely up to your personal preference. If the water goes into a tank, you can sometimes remove the tank and reuse the water, which is a good way of saving money if you plan to wash something, water plants, or just need some disposable water that doesn’t come from your own tap system.

Heat Venting

The venting system used for any AC tool is important, especially once you get beyond a level like 12,000 BTU. The amount of warm air that has to be removed from the room can be tricky to deal with, and a bad ventilation style will just vent it all right back into the room and cause the same problem all over again. Many units get around this by using a hose system, even smart portable AC options: the hose runs through a window and vents the heat outside without letting it back into the room before it leaves the hose. While this might earn a few odd looks a first if you are not used to a hose system, it can be a great way to get rid of the heat without needing a separate fan.

First of all, not all units support a hose. Some are entirely unable to fit a hose at all, and that is not something that you can really change. Regardless of where you are looking (whether it is on Amazon.com or in a real-world store), you will have to decide whether you want hose functionality before you buy anything since you can’t usually add it later as some kind of attachment or upgrade.

Second, remember that the hose has to run outside your house. This means that rooms without reachable windows (or windows at all) might need a different method. You can sometimes add a second hose to the first to extend them, but this can sometimes cause problems of its own. If you want a system like this, you will have to work out where it can be practical.

What is the Best Portable Air Conditioner on the Market?

There isn’t one single unit that can be called the “best on the market” since there are so many to choose, each with so many different features or details that you might want. Because of this, it is impossible to single out one product, or even one brand: a difference as small as wanting 12,000 BTU or wanting 14,000 BTU can be enough to completely change what kind of unit you will end up thinking is the best. While certain units may earn a good or bad reputation from their reviews, that doesn’t necessarily mean that those units will be that way when you end up using them, either. This is especially true of reviews on sites like Amazon.com since every user there could have bought the product for different reasons or purposes.

However, Amazon.com (and similar sites) do have the advantage of collecting a lot of reviews for you to read through. Always take advantage of customer and user reviews to see if there are any issues with the unit you should be aware of: you might get details on how to get the best performance out of some units or what they are best suited for when you are trying to cool down a house. You can often filter them from the top by their ranking, too, so you can skip to the poor reviews if you want to make quick checks on any bad details that you’d otherwise overlook.

Do Portable Air Conditioners Work Well?

While it is true that many portable air conditioners are going to be weak compared to their larger cousins (especially when you are looking at their relative strengths in terms of X,000 BTU), that doesn’t mean that they are worse at what they try to do. Many people make the mistake of using their portable units as a replacement for a larger cool air tool, which isn’t really what they are for: in a way, they are more like a medium to a large fan. Rather than having to cool down the entire house, these units cool down a specific area while also helping fight off humidity, dust, or other problems that can get in the air and make you less comfortable.

Of course, unlike a fan, they are also capable of directly cooling air and ventilating heat, whereas most fan designs can only move air around until it cools down naturally. This means that they are more effective at keeping a room cool compared to your average fan, even if they are still far less powerful than other air conditioners in terms of the BTU value they offer.

It really depends on what you use them for, and how. A 14,000 BTU portable air conditioner won’t be the best way to cool your entire home all at once, but it could be the best way to cool the room you are currently occupying.

Do all Portable Air Conditioners have to be Vented out a Window?

Not all units use the standard hose ventilation method. Some will use an evaporation system instead, keeping a room cool through a cool internal design that essentially forces evaporation to occur by turning the water inside them into water vapor. Instead of removing the humidity from the air, the ventless design fills uses the idea of “water is cool” to fill the air with extra water vapor, naturally cooling down the entire room without needing the heat to be pumped away.

Of course, these require a supply of water to work and can take slightly more time to set up, so they can be a bit less convention overall. They are still one of the best options for people who want to avoid window systems for whatever reason and can be more efficient at cooling you down than a fan since the cold vapor will be in the air around you.

Conclusion

By now, you should have an understanding of the best way to find a portable air conditioner that meets all your chosen criteria, whether that is BTU ratings, size, weight, cooling methods, or even just the way it looks alongside your other furniture. Remember to prioritize properly and put things like BTU above aesthetics wherever you can, and don’t be afraid to look at some of the Amazon.com products up at the top of this buyer’s guide. Even if those products don’t have the BTU or features you want, it is a good place to start, since Amazon.com has thousands of options that could each end up being your ideal option!

Whatever you end up choosing, try to be sure it is the right option before buying. As silly as it might sound, even a small change in BTU can make a product completely different from another, and nobody wants to end up with a portable air conditioner that isn’t going to keep them comfortable, happy, and protected from unbearable weather. Comfort should always come first – what is the point of having any air conditioner units at all if they won’t keep you comfortable?

Expert Tip

Not all conditioners will have their controls on top, so make sure you think carefully about where you place it. If it is blocked by something, you might struggle to adjust it, and you could also be affecting how well it works at cooling the room down.

Did You Know?

You technically don’t need ventilation to cool down a room, but it can become much less effective. If you are happy to pump the heat into a different room instead, that can work in the short-term.
