Do Air Conditioners Have To Be In A Window? (Important Facts)

This is an important question, and the answer is no. Air conditioners do not need to be in a window for them to do their job.

There are many different types of air conditioning units that can do the same thing without having to be installed in a window.

It really depends if you want a permanent or temporary solution.

But if you do want your AC unit put into a window, there are ways that you can do so safely and securely!

And you can always get a professional installer that will do the work for you.

Are there good alternatives for window air conditioners?

Alternatives for window air conditioners:

There are a few good alternatives to window air conditioners that do not require a window unit.

Through the Wall Air Conditioner

A through-the-wall air conditioner (Wall Air Conditioners) is a good alternative for window AC’s, but there are some drawbacks.

Advantages of a through-the-wall air conditioner:

  • The noise levels are very low.
  • Newer models of air conditioners are much more attractive than older generations.
  • Rapid surface cooling.
  • Air conditioning units can also keep the air dry for a more comfortable environment.
  • Filters the air and improves air quality.
  • The ability to easily control the temperature, fan power, and airflow direction right from your current location (remote control).

What you don’t might like with a wall air conditioner:

  • It is difficult to install in certain spots.
  • Although beautiful, it may not be aesthetically pleasing to place an AC in every space you want to be cooled.
  • The more air conditioners you distribute in your home, the higher the electricity consumption.

They do take up a large amount of space on the wall and can be tough to install by yourself if you do not have DIY knowledge.

Through the wall air conditioners work the same as window air conditioners. You can get them for any size room.

They look like window AC units, but they are installed inside a wall.

Portable air conditioners

A portable AC unit is not a replacement for a window or split AC. If possible you should get a conventional air conditioning unit.

These air conditioners don’t need to be hoisted up a window.

Some models use a hose that vents the hot air out of your room but comes with kits for easy connecting to windows.

Other models require no ventilation at all and can cool rooms without any windows too!

If you want an extra effective portable AC unit, consider getting a dual hose ac unit.

A dual-hose portable air conditioners are much more effective at cooling larger spaces than single-hose versions. For starters, dual hoses operate quickly because they have a more efficient process for exchanging air.

Portable air conditioning unit benefits:

  • A portable air conditioner is a good choice if you need temporarily cooling in a room.
  • They’re easy to move from room to room, as they got wheels on the bottom.
  • Installation is very easy and it does not take a lot of skill if you just follow the instructions.
  • A portable unit makes it easier to open the window and let some fresh air into the place.
  • Portable AC units work great for small rooms and can be considered when there are some difficulties in buying and installing conventional AC units.

Spot Cooler

If you’re looking for a way to cool down your personal space, one alternative option is a small spot cooler.

These units are cubes that measure 7″ x 7″ x 7″ and require cold water or ice to run.

They can provide cold air within a few feet radius, making them perfect for placing on the table next to you while in an office environment.

Benefits with a spot cooler:

  • Be cool and comfortable in seconds.
  • Keep your home or office at a comfortable temperature without breaking the bank.
  • Have relief from the summer heat with a personal air cooler.
  • Soothe your throat and lungs with the humidifier function.
  • Create a fun atmosphere for kids by changing the color of the light (or using it as a night light).

This USB air cooler is easy to use. It can be moved from room to room. You can put it in your kitchen, dorm, office, or anywhere else you want and it will cool the space and provide purified air. You can also take this air conditioner outside.

Ductless Mini Split System

A ductless mini-split system is a great alternative to window AC units if you want some more power out of your air conditioner.

This type of air conditioner is a mixture between a window AC and central AC. Mini-split units have a small condenser that goes outside, connecting to an evaporator on the wall or ceiling.

These devices give you the added benefit of cooling multiple rooms at once by linking several units together.

You can also hang them on a wall or suspend them from a ceiling, and they don’t require an open window for ventilation either!

If you’re looking for a long-term solution to your air conditioning needs, but don’t want the installation and cost of ductwork, a ductless mini-split system is an excellent choice to consider.

They are less expensive than installing central AC units with all new ducting work done at once—or having to hire someone else to do it! Plus, they offer more energy efficiency in most cases.


One major benefit of mini-split systems is that they are often quieter than other central air conditioner alternatives. Since the condenser goes outside, these units are perfect for quietly cooling your room and not bothering anyone else with a loud device in their home or office!


The high upfront cost of mini-split air conditioners, as well as the need for a professional installation, make these units rather costly.

The initial purchase price can be quite steep and it is often followed by paying to have an installer come in and properly install your unit so that you get all its benefits out of it.

Floor Fans

A floor fan is a good alternative for window air conditioners, and they do not need to be in the window. Window air conditioners do have a lot of additional features that a floor fan does not have.

If you do not have enough windows or do not want to use them all for air conditioning purposes, then buy a floor fan as an alternative.

It can also be used in an appropriate space such as an attic or garage.

  • A floor fan is a good alternative for window air conditioners if you don’t need a permanent solution.
  • A floor fan is easy to assemble and does not need any special skills or tools to put it together.
  • The floor fan will take up some floor space, but you can place it in the corner of a room and use it without taking up that much floor surface area.
  • You can adjust the angle of the floor fan to your liking.
  • The floor fans create airflow that makes it feel cooler and will also help circulate warm air out of the room more efficiently.
  • The floor fan will work in a smaller area than an air conditioner, but it is not as powerful and therefore the floor fan has to be used more often because of this power difference.
  • It can also make some noise while running so if you are trying to sleep or study then it may be too loud for comfort.
  • Floor fans do not have a lot of additional features that window air conditioners have.

Ceiling Fan as an alternative to window ACs

Installing a ceiling fan is another good option if you want to control the temperature in your home.

A ceiling fan is a nice alternative for a window air conditioner because it’s a more natural way to control the temperature in your home.

For instance, ceiling fans can help you cool off by circulating air and making you feel cooler than the actual room temperature.

The ceiling fan is also beneficial because it uses much less energy compared to an AC unit which means that not only will this alternative be cheaper but it’ll also help you conserve energy.

Ceiling fan blades:

  • Ceiling fans can come with 3 blades or more, it all depends on how much airflow you need.
  • Generally, the more blades a ceiling fan has, the less noise it makes and moves around less air.

Important things to know about the ceiling fan spin direction

One thing to keep in mind though is that some fans can spin both clockwise and counterclockwise during hot or cold months.

During the hotter months, set your fan so it’s spinning counter-clockwise – this will cause it to blow cool air down and around which helps reduce overall room temperature while giving you relief from the heat outside by evaporating sweat on the skin quicker too!

During colder months with an upswing of energy bills, we should be switching our ceiling fans over now as well for maximum efficiency since they’ll work best when blowing hot air upwards instead of downwards like before making sure everything stays warm inside no matter how low temperatures drop.

Window air conditioner

Window air conditioners do not require a window for installation, but do need to be installed in a well-ventilated area and do require some additional installation considerations.

Window air conditioners are powerful units that do not have large size requirements.

Consequently, these units can be installed into windows without compromising the space available for other items in the house or apartment.

The window unit is used as a return grill for outside air, therefore, outside allergens do come into your home or apartment when you are running this type of unit.

How does a window air conditioner work?

Window air conditioners work by absorbing heat through the coils on their front and then discharging it outdoors from their back, but they need to be placed in a window or another penetration of the structure wall for them to function.

What happens if you install a window ac unit in the wrong location?

If it is placed indoors without the discharge coils (known as condenser coils) outdoors, then it will simply circulate the heat in place.

It will actually add heat because of how powerful and strong its compressor system is that emits all those hot air from its electric motors into your home’s atmosphere.

So it’s important to install it in the right place to get the best results and effectiveness.

What do I do if the window air conditioners are too big for my windows?

There’s maybe no need to purchase a new one!

Some window AC models can be installed in both windows and walls. These models have slide-out chassis, which makes them more adaptable than traditional window units.

Before installing a window unit through the wall, make sure you know where its air vents are located.

AC’s that vent only in the back work for thru-wall installation.

If they also vent out of either side, then your wall will block those vents and this can cause efficiency issues, as well as not to mention it won’t let your model operate properly and it will probably overheat.

Different sleeve types for window air conditioners?

You might be wondering about the difference between an air conditioner with a slide-out chassis and one that has a traditional through-the-wall sleeve.

A sleeve is a metal device that holds your air conditioner in place when you install it through a wall. You need one to support the weight of an AC since the walls themselves cannot bear this burden.

The following will help you to understand what each of these is, as well as why they may or may not work for your needs:

Slide-out chassis:

Slide-out chassis air conditioners come as one unit (the sleeve and the chassis) and vent through the sides and back of the unit.

Through-the-wall sleeves:

If you get air conditioners that are rear-venting, they will work in thicker walls. Sleeves are not part of the air conditioner, you need to buy them separately. Most sleeves come with an exterior grille, but for some models, you can choose different grilles for a different look.

The energy impact of window AC units on your electric bill

But do window AC units use a lot of electricity?

Window AC units use less than ⅓ of the energy it takes to run a central unit for the same amount of time. But if you have more than one window unit, then that can quickly start adding up!


Air conditioning is one of the best inventions of all time.

It keeps us cool on hot days, and it helps keep our homes comfortable year-round.

While there are many types of air conditioners, they all have one thing in common – they don’t work if they aren’t properly installed.

There are many different types of air conditioning units that can do the same job without having to be installed in a window!

It all really depends on if you want a permanent unit or a temporary solution.

If your goal is just for temporary use, then alternatives like a portable air conditioner will be more efficient and less costly as well!

A through-the-wall air conditioner and a ductless mini-split system are great alternatives to window air conditioners.
