What is an air conditioner?

First, what exactly is an air conditioner? It’s a device that comes in many form factors that helps cool the air in the home by taking warm air, removing it, and replacing it with cooler air.

Some homes may be equipped with central air conditioning, which allows you to control the temperature throughout the entire home using the same thermostat you use to control the heat, and an outdoor-installed air conditioning unit. But this is a costly setup, and some homes, as well as apartments, don’t have it. And you might really only need to add cooling to a single room, such as an upstairs bedroom, or one floor of the home. The solution, in these cases, is to buy a portable or window air conditioner.

Types of air conditioners

If you’re looking to buy an air conditioner to cool a room of the home, you’ll probably be deciding between the two main options: a portable air conditioner and a window air conditioner.

What is a portable air conditioner?

A portable air conditioner is a floorstanding appliance that uses air from within the room to cool the area, and exhausts air, sometimes out from a hose that’s mounted at the window using an included window venting kit. Some models include a self-evaporating function that will recycle condensation back into the air, while others require drainage of water. There are also dual-hose models that include one hose to bring air inside from the outdoors, then run it out through the window, and a second hose that exhausts heated air out. Some can also vent air out through a drop ceiling or through a wall.

A model with a use will come with a window vent kit that can fit right onto your window opening to expel the air. Those that don’t have a hose require simply that you plug them in and go. But you will need to empty water periodically from a reservoir of some kind. How often will depend on how humid the air is in your room. The most hassle-free option is a more advanced self-evaporating model, since they are easy to set up and require very little, if any, maintenance.

Advantages and disadvantages of a portable air conditioner

Portable air conditioners are great if you want to be able to move them from room-to-room (although note that if you have one that exhausts air through the window, you’d also have to remove the hose and install it at another window as well.) They’re also ideal for rooms without windows, such as a basement office or play area. They are usually quite large and heavy, but often come on castors so you can roll them around, which makes storage during the winter easy as well. They are also usually quick and easy to set up in minutes, so ideal if you’re looking for a quick fix to an especially hot home.

But since they are larger, you might not want to get one for a small room since it will take up space. And some sources suggest that they aren’t as effective in cooling as a window AC unit for larger spaces, though there’s no definitive evidence on this, and it might also depend on the unit and brand you choose. (If you’re worried about efficacy, it’s always a good idea to check out trusted sources for online reviews.)

Before we sprung for central air conditioning in my home, I used a portable air conditioner in my son’s approximately 100-square-foot bedroom, and it worked perfectly to cool the space. Keep in mind that if you are in an apartment or rented home, you might not be permitted to install a window AC, or may be worried about doing so, so a portable unit could be your best option (not to mention easiest to take with you when you move.)

Portable air conditioners can sometimes run pretty loud, so you might want to get one with a timer function, so you can have it automatically go off at night once the room has effectively cooled, or during your baby’s naptimes.

Though you never know: some people might find the hum of the unit soothing.

What is a window air conditioner?

By contrast, a window air conditioner is installed right into a standard-sized window opening, exhausting hot air outside and bringing cool air in. They’re much smaller, and more unobtrusive in design.

 

Advantages and disadvantages of a window air conditioner

Window air conditioners are more discreet, and don’t take up any additional space in a room since they fasten directly to the window opening, making them ideal for small rooms or apartments. There’s also no drainage to worry about.

However, you need to make sure it will fit onto your window. I live in a 100-year-old house, for example, which has unusually small windows upstairs, which meant we had to cut the window mount for our portable air conditioner in order for it to properly fit in my son’s bedroom window. If we had gotten a window air conditioner, we would have had to make sure to measure the window opening and get one that would fit perfectly.

Window air conditioners can sometimes be quieter than portable air conditioners, and are often more affordable as well. They can be removed and stored away for the winter, but not as easily as a portable unit.

What are BTUs in an air conditioner?

One of the most important things you need to look at when selecting an air conditioner, regardless of the type, is BTUs, which stands for British Thermal Units. This is the number that measures the amount of heat an air conditioner can remove from the air over a certain period of time, relative to the room’s size. Essentially, the higher the BTUs, the greater capacity the air conditioner has to cool air in a larger room.

So for example, in my son’s aforementioned room, which is about 100 square feet in size, a 5,000 BTU air conditioner would suffice to effectively cool it. But getting a 6,000 BTU unit might help further cool down the hallway when his door is left open. Meanwhile, a 14,000 BTU air conditioner can cool a room up to 640 square-feet in size, which is ideal for a main floor living room, or larger basement playroom that tends to get hot in the summer. You can check out the handy chart in this article to determine the appropriate BTU number for your room.

What to look for in an air conditioner

When deciding on which air conditioner is right for you, there are a few things you should consider, and questions you should ask yourself.

BTUs and size of room for an air conditioner

air conditioners buying guide - window air conditionerAs mentioned above, look at the BTUs relative to the size of your room to make sure it will do the job effectively.

The size of the room might dictate what type you decide on in another way as well: if the room is small, you might want to go for a window air conditioner that won’t take up too much room. If you have the size to accommodate it, or a small area where it can comfortably sit, you might prefer a portable air conditioner that is easy to set up and get going right out of the box, without any installation.

Where do you plan on putting the air conditioner?

Are you looking for a solution to cool a specific room in the home, such as your child’s nursery, or the master bedroom? If so, a window air conditioner might make the most sense. But if you think you might want to move it around, and cool different rooms, like the guest room when the grandparents are staying over, look at a portable air conditioner instead.

You also need to consider things like noise: how loud is it, and will it distract your baby, or a light sleeper? If so, look for one that touts extra-quiet operation. And also make sure a window AC or a portable air conditioner’s exhaust hose set-up will fit properly in your window, especially if your windows are unusually small or large.

But it will, of course, take up much more room.

How much space do you want to cool with an air conditioner?

If you’re looking to cool an entire house, you could opt for multiple window air conditioners for each main room, or get a portable air conditioner to place on each floor of the home that you can move around, or tilt in the desired direction to cool down the space you’re currently in. But you may just be looking to cool down one or two rooms of the home, like the bedrooms, or a small apartment, in which case, a single unit should be enough. If you’re renting an apartment, while a portable air conditioner is larger, it might make more sense since it does not require any type of installation, and you can roll it around if it’s on castors for cooling wherever it’s needed.

Costs and environmental friendliness of an air conditioner

air conditioners buying guide - portable air conditioner roundThe upfront cost of the unit is only one consideration: window ACs are usually less expensive, whereas portable air conditioners with high BTUs can be costly, but effective for larger rooms, or cooling entire open concept floors of a home.

Whichever option you choose, look for an Energy Star or other environmental-type rating to ensure not only that it runs efficiently, but that it won’t use too much electricity, and cause a massive jump in your bills.

Ease of installation and maintenance of an air conditioner

If you don’t want to have to be constantly draining out the water, look for a model with a function that will evaporate the water and recycle it back into the air, so it’s easy and maintenance-free.

Portable AC units are usually the easiest to set up, since you simply plug them in, position the hose to vent out of the window if you get such a model, and you’re good to go. They usually also have easy-to-clean filters. If you don’t plan on moving it too often, consider getting one that exhausts out the window, which will require a bit of extra set-up, but it means there’s no water drainage to worry about. But if you want a quick and easy set-up that you can move from room-to-room, consider a unit that collects the water from condensation in a bucket that you need to empty as needed, or a self-evaporating model.

Convenience features of an air conditioner

You might appreciate having certain convenience features, like a handy remote to adjust the temperature of a portable air conditioner in the living room from the comfort of your couch, or a timer function so you can set it to cool your child’s room overnight, then shut off at 7 a.m. each morning once he’s up for school. Some also have multiple settings to adjust the cool level, which is perfect to toggle as the temperature outside fluctuates.

Will you need accessories for an air conditioner?

You shouldn’t need any accessories for a portable or window air conditioner, but there are some items you can get, like side panel kit that can replace worn side panels and help reduce drafts; and a cover for a window air conditioner that can protect it from damage in the winter if you do leave it installed all year, and to help reduce drafts and heat loss.

Bottom line about air conditioners

There are so many things to consider when deciding on an air conditioner. Portable air conditioners are versatile, and usually come with a lot of options, like a timer, multiple settings, and a remote, which make them attractive options, even if they tend to be more expensive. But window ACs might appeal to the budget-conscious person just looking to cool a single room with an unobtrusive design, low maintenance, and little noise.

In the end, the most important things to look at are the BTUs relative to the size of your room, what the installation process entails and how handy you are, overall maintenance, price, fit, energy efficiency, and look. Ticking off each of these boxes, you’ll find the perfect one to meet your needs.
