What Should You Look for in a Casement and Sliding Window Air Conditioner?
A lot of people probably don’t really think too much about what they want in an air conditioner unit. They just think “Does it make the room cold? Great” and then go on their way. This is obviously the most important aspect of an AC unit, but there’s more to it than that, and we want to make sure you don’t ignore the finer details. That’s why we’ve added this quick rubric of the criteria we used to assess the best air conditioners out there. After you finish this short section, you’ll be such an expert you’ll feel ready to get a job in HVAC, and you’ll be well on your way to buying the best air conditioner for your home.
Criteria #1: Cooling – Yes, obviously, cooling is the most important aspect of an AC unit. And, obviously, the main way to measure this will simply be how cold a unit is able to make your room. But a somewhat overlooked aspect will also be the area coverage of your air conditioner. If you’re in a bigger room, certain AC units just won’t cut it, even if they can get down to 60 degrees, that won’t help if you can only feel it right in front of the machine. Area coverage, which is directly correlated to the lowest temperature possible, is measure in BTUs, which stands for British Thermal Units. The more BTUs, the more space your air conditioner will be able to cool. There are factors other than space that might necessitate buying a machine with more BTUs, but we’ll get to that later.
Criteria #2: Size – Your window air conditioner unit can only be as big as your window will allow. I can’t pretend to know what your living situation is like or what size AC you need, but we’ll make sure to include the dimensions (and weight) of all of the products on our list. We don’t want you buying a brand new AC only to find out that it doesn’t fit in your window.
Criteria #3: Volume – If your sliding window air conditioner is so loud that you can’t hear yourself think, you’re just trading one problem for another, and that’s not the sort of “solution” to your summer heat problem that we’re looking for. Of course, there will be a certain correlation between strength and noise, but we’re looking for the gems of the market that manage to be strong but silent. While a powerful machine that’s why too loud is bad, a quiet machine that’s far too weak to cool you down is even worse.
Criteria #4: Price – We’re not here to make you spend a ton of money for no reason. Meeting this criterion is less about being cheap and more about justifying your price. We’d rather buy an expensive product that’s cheaper than it should be than waste money on a cheaper product that isn’t worth the money and that will just break on you or not perform well. Luckily, window air conditioners span the full spectrum of price points, so everyone should be able to find something that matches their budget and the features they want.
Here’s How We’ve Determined the Best Casement and Sliding Window Air Conditioners
We measured the specs of the top products on the market against our listed criteria to see how they held up and if they’re worth buying. We then checked customer reviews, blog posts, and “best Casement and Sliding Window Air Conditioners” articles to see if the products on our list performed as advertised. We’ve also included any extra features that didn’t fit squarely into our criteria, and we made sure to include a wide variety of products that satisfy different niches and price points so that everyone can find the casement and sliding window air conditioner that’s perfect for their needs and their wallet.
And without further ado, here is our list – tailored to your specific needs – of the best Casement and Sliding Window Air Conditioners.
#1: Midea EasyCool Window Air Conditioner (Best Value – All-Purpose)
Our list gets started with the affordable, simple, and effective Midea EasyCool Window Air Conditioner. It’s pretty rare that you get everything in one package at a price that’s not completely unreasonable, but this Midea sliding window air conditioner manages to pull off the impossible. to start things off, the Midea EasyCool Window Air Conditioner gives you 8,000 BTUs that will have you nice and cool as quickly as possible, and it boasts a coverage area of 350 square feet, so this unit is great for hosting some friends during the dog days of July and keeping a bigger room at a liveable temperature. Plus, with Midea’s 3-in-1 technology, you get air conditioning, dehumidification, and fan-only modes all in one machine that will increase the overall comfort of your home no matter what the weather is. Our number one sliding wall air conditioner has a frame of 16.02 x 18.54 x 13.39 inches, which makes it one of the more compact models out there, but at about 50 pounds, it’s still pretty heavy. It’s definitely worth bribing (er, rewarding) a friend or two with some pizza to get them to help you install the Midea EasyCool Window Air Conditioner. Of course, weight aside, the installation will not be very difficult. The small frame makes things much easier, and aside from a screwdriver, all of the necessary accessories are included with this sliding window air conditioner unit.
The Midea EasyCool Window Air Conditioner boasts an eco-friendly mode if you’re worried about running up your electric bill, and it has a timer so you can always come home to a nice and cool home, or set this window air conditioner to turn off in the middle of the night so you don’t wake up shivering at 3 in the morning. You also have multiple fan speeds so you don’t need to worry about overdoing it and constantly turning the air conditioner on and off in a weird game of temperature ping pong. It also has a noise level of 51.9, 53, or 55.5 dB depending on the setting selected. For some context, the average speaking voice is somewhere in between 50 and 65 decibels. That means that, while I can’t pretend you won’t hear this machine at all, you’ll have no problem speaking over it and having a normal conversation. To cap things off, the Midea EasyCool Window Air Conditioner comes with a remote control, so you never have to get up to adjust any of the settings. And if that didn’t make things easy enough, the filter of this sliding window AC is easily washable with water, and an LED on the unit will tell you when it’s time for a rinse.
With close to 3,000 reviews on Amazon and an average of 4.5 stars, you know what you’re getting with the Midea EasyCool Window Air Conditioner. This reliable AC has the crowd’s seal of approval, so you don’t need to worry that you’re going into uncharted territory. Customers praised this product for its wide coverage area and for being easy to install, with one reviewer simply exclaiming “All Boxes Checked.” Of course, the amazing price of this product can’t go unmentioned; it’s more than $100 cheaper than most of the other sliding window air conditioners out there. And to make things even better, it comes in several different models, each with its own specs and BTU count. The fewer BTUs, the cheaper the air conditioner, so everyone can get exactly what they want for the price they’re willing to pay with this Midea sliding window air conditioner. That makes the Midea EasyCool Window Air Conditioner the best value out there by a long shot, and there was really no question that this air conditioner would be our number one pick.
#2: Frigidaire FFRS1022R1 10000 BTU Air Conditioner (Best Overall Air Conditioner)
So, you weren’t too enthused by the Midea EasyCool Window Air Conditioner? No worries, we have plenty of more options to show you, the first of which is the Frigidaire FFRS1022R1 10000 BTU Air Conditioner. Frigidaire is just about the premier name in sliding wall air conditioners, so it’s no surprise that they managed to nab out runner-up spot, which is dedicated to the strongest machine out there, regardless of price. If money is no object for you and you’re willing to splurge for the best air conditioner out there, then you’ll have to consider the Frigidaire FFRS1022R1 10000 BTU Air Conditioner for your home to help you get through the summer. Here are some reasons why this Frigidaire product will convince you to pass on our top-ranked AC unit from Midea.
Reason #1 to Choose This Product: More BTUs
The advantage here is pretty simple. More BTUs means more cooling, which means more relief from that blistering heat when the temperature starts to climb up into the 80s and 90s. With 10,00 BTUs, the Frigidaire FFRS1022R1 10000 BTU Air Conditioner is sure to keep you cool no matter where you live. So whether you’re in the brutal humidity of a Miami summer or the listening desert heat of Arizona, the Frigidaire FFRS1022R1 10000 BTU Air Conditioner is guaranteed to get the job done. Plus, all that BTU gives this casement air conditioner an extra 100 square feet of area coverage over the Medea sliding wall AC, for a total of 450 square feet. You can throw a full-scale party in a large room, and the Frigidaire FFRS1022R1 10000 BTU Air Conditioner will still keep every single person cool and comfortable.
Reason #2 to Choose This Product: An Absolute Unit
Going along with that extra BTU and the incredible area of coverage, the Frigidaire FFRS1022R1 10000 BTU Air Conditioner comes in with a frame of 23.5 x 14.5 x 20.25 inches and weighs a whopping 72 pounds. While that weight and size won’t be very fun during installation, it’ll add some horsepower to this machine, as more machine means more fan space, which means more cooling. While a lot of customers just won’t have the right window to handle this beast of a casement air condition, it’s the best way to go if you have the right setup. You’ll never be hot again with the Frigidaire FFRS1022R1 10000 BTU Air Conditioner.
On top of its high-powered frame and machinery, this premium-grade casement air conditioner boasts pretty much all of the same great features as the Midea EasyCool Window Air Conditioner. That means you’re still getting a remote, multiple fan speeds for when you need a more delicate touch, and an LED that will tell you when it’s time to change the easy-to-wash filter. You also have cooling mode, energy mode, and fan-only mode, as well as a sleep mode and a timer that you can set to your ideal schedule. You also get dehumidification up to 3.4 pints per hour, and the Frigidaire FFRS1022R1 10000 BTU Air Conditioner boasts a high energy efficiency ratio that will make sure this casement air conditioner unit doesn’t ruin your green streak. Finally, this high-powered AC unit is compatible with any window with a minimum height of 21.5 inches, and a maximum height of 40 inches, while the minimum window width is 15.5 inches.
As we mentioned earlier, Frigidaire is the king of the hill in the air conditioner business. Basically every list you’ll see of the best window air conditioners will be topped by a frigidaire product, and it seems that ours is no exception. Frigidaire boasts powerful machines that don’t mess around and that get the job done. Our casement air conditioner offers basically every feature out there and has some of the best specs to boot. The only issue is that it’s very expensive, which will obviously discourage some customers. If you’re not ready to pay with an arm and a leg for your AC, then definitely stick with the Midea EasyCool Window Air Conditioner. But if you want nothing but the best, then the only choice for you is the Frigidaire FFRS1022R1 10000 BTU Air Conditioner. One last thing, given its extra horsepower, you should, unfortunately, expect this air conditioner to be on the louder side of things.
#3: Della 6000 BTU Window Air Conditioner (Best Low Cost)

So far we’ve given you a nice and affordable sliding window AC unit followed by one of the most expensive products on the market. Now we’re rounding things out by showing you one of the cheapest window air conditioners available that’s perfect for everyone out there who needs to save a buck or two. I know how costly setting up a new place can be, and, of course, it’s never a bad time to watch your spending. The Della 6000 BTU Window Air Conditioner is sure to make cooling your home feel a little more affordable, and you’re walking away with a product that’s not half bad, so you don’t need to worry that you’re ripping yourself off by buying a crummy machine.
This affordable Della air conditioner boasts an area coverage of 250 square feet thanks to its 6,000 BTUs and a 46 pint/24hrs dehumidification rate. Just like our previous air conditioners, it comes with a remote control for quick and convenient access, so you’ll never have to get up to make your room the perfect temperature. It also has a sleek and easy-to-read display panel that shows clearly labeled buttons for all of the features this low-cost sliding window AC unit offers. The Della 6000 BTU Window Air Conditioner has cool, dry, fan, and auto cooling modes, as well as three different fan speeds and an extra automatic fan speed. Next, you have the same filter light monitor that we’ve grown used to, along with a timer, sleep mode, and eco-friendly mode. As you can see, the Della 6000 BTU Air Conditioner is right up there with all of the top products when it comes to features, the only real drawback is the lower BTU count, and the fact that it’s just as loud as our number one air conditioner despite being a bit weaker. Of course, a nice byproduct of that lower BTU count is that the Della 6000 BTU Window Air Conditioner has a relatively compact frame of just 15.26 x 13.45 x 19.04 inches, so it’ll be nice and easy to fit this AC into your window. And just like with the Midea EasyCool Window Air Conditioner, the Della 6000 BTU Window Air Conditioner has different models available, each with its own BTU count and a scaled price, so if you’re living in a small space and can do with fewer BTU, you can spend even less money. Of course, you can also beef this AC up a bit and still spend less money than the cost of some of the competing machines. As for the 6,000-BTU model that we’re reviewing, there’s no question that it’s more geared towards smaller spaces than our first two window air conditioners, but it still covers a decently sized space, and it has a price that’s pretty hard to beat. So if you don’t have a massive living room and you can afford to accept fewer BTU, then go ahead and save your money by purchasing the Della 6000 BTU Window Air Conditioner.
#4: Emerson Quiet Kool 5,000 BTU 115V Window Air Conditioner (Best Dirt-Cheap Window Air Conditioner)
Replace Image below with Amazon SiteStripe Image
We already gave you a nice and affordable option in our previous air conditioner from Della, but if that just wasn’t within your budget and you need something even cheaper, then you’ll need to look at the Emerson Quiet Kool 5,000 BTU 115V Window Air Conditioner. I’m not going to sugarcoat it, this product does not offer the more advanced features that we’ve spoiled you with so far, but it costs almost nothing, and it’ll keep you cool. And isn’t that all that really matters? As the name suggests, The Emerson Quiet Kool 5,000 BTU 115V Window Air Conditioner is backed up by 5,000 BTU which give it an area coverage of about 100 to 150 square feet. Considering this is the weakest AC unit on our list, that’s nothing to sneeze at. But, as the saying goes, you get what you pay for. The big loss from your efforts to keep things cheap with this AC is that you don’t get a remote control, and you don’t have any of the fancy modes or timers that our other sliding wall air conditioners boast. You have two knobs; one for fan speed, and one for temperature. That’s it. Of course, if you appreciate simplicity, that can actually be a good thing, but most of our customers will want at least some of the features that have been detailed on our list up until this point.
What you see is what you get with the Emerson Quiet Kool 5,000 BTU 115V Window Air Conditioner. Despite, or maybe because of, its simplistic build, this product was reviewed very well by the paying customers, who praised it for being easy to install and incredibly quiet, so there are certain advantages to going with a weaker machine. Honestly, unless you have a massive living room, this will cool things down just fine, so the main reason you’ll want to splurge and go for one of our fancier casement and sliding wall air conditioners is if you specifically want the nice extra features. But if all you want is to escape the heat, and if you want to save your hard-earned cash, then it’s inarguable that the Emerson Quiet Kool 5,000 BTU 115V Window Air Conditioner is the perfect choice for you. This air conditioner is so cheap you’ll just be pulling coins out from underneath the couch cushions to pay for it.
