Whether you’re preparing for the weather or your blood seems to run hotter than that of your housing companions, window air conditioners can prove to be little blessings.
If you have an enormous house (maybe you have a mansion?), you may want to invest in a few window air conditioners! Who says you have to hire a crew to install fancy cooling equipment in your vacation home?

We love the fact that window air conditioners can cut the cost of our utility bills.

Sure, one or more can be used in place of central heat and air, but if you have both (or a split type air conditioner), you can watch the cost of cooling your home go down significantly over time.

Remember us mentioning those of us that tend to be a little warmer than our family members or roommates might be?

Window air conditioners will quickly become a miserably-hot person’s best friend on a scorching summer day. (If a pool isn’t a realistic investment for your loved one, consider one of these instead!)

When Shopping for Window Air Conditioners:

There are several things to think about. Long before you’re ready to key in your credit card information, you should have done plenty of research, taken measurements, and considered the desired outcome.

There are some basic questions we should ask ourselves and then there are some technical things we need to know about our purchase.

Let’s start with the basics, like our goals, our budget, and what window air conditioners are best for.

  • What can I expect a window air conditioner to do?
    • Judging by its name alone, we’d say it’s fair to assume that they’d be good for cooling a room.
    • Not only can they cool, but many are capable of heating rooms as well!
    • They are not meant to cool or heat entire houses. If that is your goal, as we mentioned, you may want to invest in a few rather than one.
      • That being said, some units are quite powerful and can provide air to a larger space than we expected.
    • Most are not designed to work like central air conditioners and will require manual operation and monitoring. There are some exceptions!
  • How much do they cost?
    • This factor obviously varies greatly depending on the manufacturer, features, Energy Star ratings (or lack thereof), and more.
    • Generally speaking, you could expect to spend anywhere from $200 to well over $1,000 on a window air conditioner.
      • That’s why these are great for in-betweeners that aren’t quite ready to spend over $10,000 on a new central unit just yet!
    • As far as how much it costs to run one, that depends on how much you pay for electricity in your area as well as the technical specifications of the model.
      • There are extensive formulas available online for calculating how much you can expect to spend on this unit monthly but that process might take some time!
  • Do they all make noise?
    • Unless you’re willing to spend crazy amounts of money, we’re going to have to say yes!
    • Most are not unbearably loud but many are very noticeable.
      • Those of you that have a hard time sleeping through the sound of a box fan or a faucet running will probably want to invest in earplugs or a very quiet model.

Now, onto the specifics. There are some terms and acronyms we need to learn if we’re planning on doing this without hiring a professional.

Along with learning some of the terminologies that will influence our decision, we also need to take a few measurements and do some brainstorming.

  • How big or small should I go?
    • That depends on the size of the window, the size of the room, and the temperature you wish that room to reach.
    • Be sure to check the height, width, and depth of a unit.
      • The weight is important, too, so you can get a helping hand if it’s too heavy for you.
    • Figure out the square footage of the room you wish to place the appliance in.
      • There are window air conditioners that can only cool 100 sq. ft. rooms and there are some that can handle 500 sq. ft. or more!
    • Consider the outside temperatures and the temperature you’d like the room to reach.
      • If you live in a blistering-hot area and want to enjoy temperatures below 70 degrees indoors, you don’t want to get a unit that can’t live up to your expectations.
  • Does it matter where I install it?
    • Yes. The type of window air conditioner you get depends on many things, including this.
    • Remember, heat travels up, so second-story units will probably need to be more powerful than a ground-floor one.
      • If you have a sunroom and you want to put a window unit out there, the amount of direct sunlight affects your cooling needs, too.
    • Take note of any other environmental influences that will clearly have an impact on your technical requirements.
  • Does it need to have a specific setting for pulling heavy loads of moisture out of the air?
    • Most units have filters that can attempt to do this hourly anyway, but if you live in an overly humid home, this feature might matter more than others.
  • What are BTUs?
    • British thermal units. This is a measurement that helps us determine the amount of energy it takes to move water one degree.
    • A basic guideline we found suggests that:
      • a 150 sq. ft. room needs a unit with 5,000 BTUs.
      • 250 sq. ft. = 6k, 300 = 7k, 350 = 8k, 400 = 9k, 450 = 10k
      • Rooms between 550 sq. ft. and 2,700 sq. ft. will need between 12,000 BTUs and 36,000 BTUs.
      • (please look up more BTU charts for specific calculations)
    • So room size isn’t the only factor… people are, too!
      • If you expect there to be 3 or more people in a room at any given time, you should calculate necessary BTUs by adding ~600 per person.
    • If you just can’t be bothered with the details, opt for too much rather than too little.
      • The more BTUs, the better, in most cases. Just know that the unit might turn on and off more frequently and therefore may require repairs so don’t bite off more than you can chew!
  • What is an EER?
    • An energy efficiency ratio.
      • The higher, the better. Premium, super-efficient models should have ratings over 10.
      • This is where companies like Energy Star come in, helping us calculate how energy efficient a product is without doing too much work ourselves! (UL Listed and/or AHAM-certified is nice, too).
  • Will it require maintenance?
    • Absolutely! Unless you’re someone that doesn’t mind replacing or disposing of products after a short amount of time, proper care routines will lengthen an appliance’s lifetime.
    • Filters should be cleaned monthly (if not more often) or replaced as suggested by the manufacturer (usually 1-2 months).
    • Coils accumulate a lot of dust and dirt so check these often if you don’t want your unit to bump up your utility bill or give out during an abnormally hot day.
    • You don’t ever want to work on or clean a unit that is plugged in. Please do plenty of research before deciding to take the unit apart!
  • Can I leave it installed year-round?
    • That depends on the specifications of the model!
    • Some can take the weather change and some cannot.
      • Look into whether or not you have to place a protective cover over, or remove the window unit, or just let it chill during winter months.
      • As we mentioned earlier, some window air conditioners can heat as well as they can cool. Just read your manual.
  • Does it require additional support?
    • Not all window air conditioners can stay in place without any help! Some are much too heavy and/or bulky for this.
    • Some models will require outdoor support! Please do not overlook this. Most manuals should tell you whether or not a model needs this.

There are certainly many more considerations to keep in mind when making this decision but that should be enough to get you started! Now, let’s take a look at the window air conditioners that won us over.

  • Measures approximately (19″W x 21.5″D x 14.6″H) and doesn’t weigh a ton like many comparable models.
    • Weighs a little more than 60 pounds.

The Window Air Conditioners That Were the Coolest

Now, it should be noted that we don’t live in an unbearable climate so our cooling needs could be much less significant than your own.

We were factoring in outside temperatures falling between 65 degrees and 90 degrees in the warmest months of the year.

We were not relying on any models to have remote controls or copious dehumidifying capabilities because we did not have extreme needs.

However, according to our research, most of the models were able to meet the needs of their users across the country when taking other factors into consideration.

If we had to choose one out of all the best window air conditioners we looked into, we’d have to choose the Koldfront.

It’s powerful, relatively lightweight, and completely affordable! We also love all the extra features, including the sleep mode and the remote control.

Thank you for learning about window air conditioners with us and we hope you find something to help you cool off!
