The main difference between window and wall air conditioners is their location. Window ACs are placed on a window sill, and wall ACs are placed in an exterior wall. Window air conditioners tend to be less efficient since some of the air is lost through the window and they take up window space, while wall air conditioners can be more time consuming to install but make for a more permanent, cleaner looking solution.
All air conditioners are not created equal.
When it comes to choosing the right type of unit for your space, it is important to know the differences between the available options so that you can make sure that you are making the right selection for your space.
Two common types of air conditioners that many people buy this time of year is an individual unit –– either a window or through the wall air conditioner. These ACs are both used to cool single rooms or spaces as mentioned above.
While both achieve the same end goal, there are some aspects of each that can be more beneficial depending on the type of space that you have. Here we will take a look at both types of air conditioner, and discuss some of the characteristics of each as well as some pros and cons, so that you can be sure you’re making the best purchase.
What is a window air conditioner?
Window air conditioners are often the saving grace of the summertime. As a fairly inexpensive, easy-to-install air conditioner, window units are perfect for the DIY-phobic. All you need is an available window and a power source, and you are off and running.
Usually window air conditioners have a BTU range from 5,000 to 36,000, meaning they can cover an area from about 100 to 1,650 square feet.
Pros of Window AC Units
- One of the most affordable air conditioner options
- Easy to install
- Flexible (can be moved easily)
Cons of Window AC Units
- Can be noisy
- Visual appearance
- Takes up window space
- Short term solution
What is a Through the Wall Air Conditioner?
Through the wall air conditioners run similarly to window units, by retrieving air, running it through coils, then sending the cooled air into the room. They are installed in a hole in an exterior wall, and require installation of a sleeve due to their weight.
These units have a BTU range between 7,000 to 15,000, with a coverage area between 200 to 800 square feet.
Pros of Through the Wall Air Conditioners
- Save on space in a room
- Lasts a long time and is a longer term solution
- Easy to replace when you have an existing sleeve and most units are industry standard sizes
- Doesn’t take up window space
Cons of Through the Wall Air Conditioners
- Complicated first time installation
- Smaller coverage area
Similarities & Differences Between Window and Wall Air Conditioners
When deciding between the two, there are some other similarities and differences worth taking note of.
One of the biggest differences between window and wall air conditioners is their location. While one is installed right into an exterior wall, the other is placed on a windowsill. Some people may not like the fact that a window air conditioner takes up precious window space. It’s harder to enjoy a view when an AC is blocking. Through the wall air conditioners are easier to somewhat hide in a room, and don’t take up as much space.
Both types of units can be efficient in that they are often used to cool a specific room or section of a home and can be turned on and off when needed. However, through the wall air conditioners tend to be a bit more efficient since they do not have as much opportunity for air to leak out through the window.
Window units tend to have a higher BTU range, which means that they are more powerful and can cool a greater space, but make sure to check the BTUs for your space to make sure you are getting the right power for what you need, and not too much or little.
Both window and through the wall units are fairly inexpensive to purchase, but the added necessity of installation for through the wall air conditioners makes them slightly more costly at the outset. However, the added efficiency of the through the wall units could save you money on your electric bill in the long term.
Long-term or short-term solutions
If you are looking for an easy cooling solution for your home, both of these types of units are great bets. For more of a short-term solution, window units can be a solid option since they are cheaper and tend to not last as long as the alternative. On the flip side, through the wall air conditioners can be better long-term options, as they are more permanently installed in the home and last longer. They are also easier to replace since an existing sleeve is already installed when the need for a new unit comes.
How to decide which to buy
When deciding on which type of air conditioner you’d like to buy, start with the room or space you’d like to cool, whether it’s a basement, attic, sunroom, addition, or the like. Measure the square footage, and use our BTU calculator to figure out how much power you’ll need, which can be an easy way to narrow down your options.
From there, you can see which one makes the most sense for you.
If you’re looking for a quick, powerful and easy way to cool down without much cost or installation hassle, window units are the way to go. But if you’d like more of a long-term, reliable solution and don’t mind paying a little extra to get it installed, through the wall ac can be a great choice for many people.
