Best Window Air Conditioner 2023 – How to Choose a Good One

When the summer heat is at its peak, you need to find an effective cooling solution. Many people opt for pedestal or tower fans; there are others who go in for the whole house window air conditioner. But these options can prove too expensive. That is when one should consider Window Air Conditioners that offer good value for money and are smart enough to cool rooms quickly.

We have carefully compiled a list of 10 best window air conditioners that will help you beat the heat without shelling out too much money. Before we take a look at this list, let us understand how window ACs work, their advantages & disadvantages. We’ll also look at what makes a product great – features it must so as to meet your requirements.

A window air conditioner is essentially a split AC. Just like the other types of ACs, it has an indoor unit that rests outside your house attached to piping that carries cold refrigerant into the room. The piping extends into an opening in your home’s wall or window. The appliance works by pulling hot air inside the room out and pushing cool air inside through the outlet vent, until the desired temperature is reached. It also dehumidifies this air, removing excess moisture in summers. Some models come with additional features like heating and speed cooling functions which can be used when necessary. Think of it as an efficient alternative to portable AC devices available in the market.


You can place the window air conditioner anywhere in your home that has a suitable outlet and outside wall or window opening to accommodate the unit’s piping. It offers convenience especially when you’re looking for an AC unit that does not take much time to install – no drilling required! Compared to other models, it is comparatively quiet, and comes in compact designs (sleek and space-saving). The indoor coils utilize copper tubing rather than aluminum like its counterparts.

This helps in faster heat transfer, thereby allowing you to relax faster even on hot nights. Most models use R410A refrigerant which is eco-friendly; it loses less moisture than the previous standards such as R22. Some window ACs come with Energy Star certification, which means they are designed with energy conservation features. They come equipped with intelligent sensors that detect the level of humidity and temperature in your room to maintain your desired climate.


Initial installation costs more than central ACs simply because it comes as a split system like most window fans or air purifiers. You need to hire technicians who know how to install them; these professionals charge an average of $100-$150 for their services. Window ACs cannot cool down large rooms efficiently unless you have installed multiple units – some models can cool one bedroom or studio apartment at best.

There are also reports of faulty wiring models giving shocks due to excess moisture, so ensure you buy from trustworthy brands only! Also, it takes time to cool down the room. Moreover, it does not dehumidify your indoor air well, so you will need supplemental dehumidifiers or air purifiers in summers.


Now that you have understood how window ACs work, let us move on to picking one for your home. There are several factors to consider when choosing a window air conditioner other than size and cost – these will determine if the product meets your requirements or not. We have listed some of them below:


Cost is an important factor while buying an appliance because it determines whether this item fulfils its purpose or not. Do you want to buy a cheap AC unit but have high electricity bills at the end of summer? Or maybe you need an expensive product that can cool down your large rooms efficiently? Both these choices are valid, but go for window air conditioners that are cost effective and use less energy per degree cooled. You also need to consider how much space you have in your home – if it is limited, it would be better to invest in smaller units instead of buying larger ones with enhanced cooling capacity.


As consumers, we often think about upgrading our appliances once every 3-4 years; why wouldn’t we do this for central ACs – ones that cool down more than one room? In fact, if you can afford it, go for a central AC without any doubts! However, there are several reasons why you should consider buying a window air conditioner instead of going for a conventional model. The first one is space limitations – you might have a large home but no suitable space to fix a window unit.

There is also the option of installing two smaller units together in your bedroom and living area; this will last longer and cool your rooms more effectively. Also, if your house was built before the latest energy-efficient standards came into place (which is around 2012), do not buy an expensive new central AC unit since they cost more money to run compared to the old ones. Window units that were made before this period are cheaper to run and easier on your electricity bill.


Modern window ACs are economical in use since they come with features that ensure energy efficiency. They have built-in sensors that detect the room’s temperature and humidity levels, automatically adjusting its thermostat settings for optimal performance. In fact, most AC units will reduce their output when you turn off the main switch or if you leave home. These models have an installation type of split system which makes them efficient in cooling rooms adequately – they can cool a house just as effectively as a central AC unit! The only difference is that it comes in two parts: one stays under your window while the other part goes inside your house/room.


Window ACs come with manufacturer warranties of 1-3 years depending on the model you choose – it is crucial that you check this information before buying a unit, to ensure nothing goes wrong after making the purchase. If something does go wrong, contact the customer service center and they will assess your product for free! However, there are also some models which have no warranty period whatsoever so if possible, go for products with at least one year of guarantee.


Window air conditioners are not expensive when compared to central ACs since they are meant to cool small areas only – you can find a powerful cooling system under 100$/£110. On the other hand, central ACs are more expensive but they have a wider reach and can cool large rooms or entire apartments at once. The same model might cost you 500-1000$!/£500-1100 in its split system version. Furthermore, you need to consider the cost of installation – some people prefer using their own skills while others hire professionals which can raise costs after buying an air conditioner.

Buying Guide:

How to Choose the Best Window Air Conditioner

If you’re looking for a new window air conditioner, there are many things you must take into account before making your purchase. Here are some of the things that you should look at before deciding on one unit or another:


Air conditioners come in different sizes, depending on the size of the room they’re being used for. If you choose a unit that’s too small, there won’t be enough cool air to cover your whole apartment/house; if the AC is too big, it will keep cooling even outside the house and can become very expensive to use. You must find an AC that fits perfectly inside your living space – adjust its power level until you reach maximum efficiency – this usually means just right


There are two types of units which you can buy for most Windows:

Window Units – these are cheap, lightweight and easy to install – all you have to do is open the window, place the device inside, close the window and turn it on. This type of ACs are usually smaller in size, so you can’t use them for larger spaces; they also require permanent installation- if you move house often or use different windows regularly this could be a problem

Split Systems – these types of air conditioners don’t require permanent installation – they usually come with an outside unit (the compressor) which is placed outside your home/apartment by an external unit. One great thing about these units is that they’re really quiet when working – plus, if the compressor breaks down, you can easily replace it without having to buy a new unit.

Winning Combo: Window units + split system

Installation – while window units are easy to install, split systems require that you hire a professional to do the job for you – this means paying extra money to install the compressor outside your home. Another drawback is that you’ll need space for both units outside of your house/apartment, so if there isn’t enough room, you won’t be able to use this type of AC

Power Source – most window air conditioners are powered by electricity – some users have reported problems using them during brown-outs or black outs but nothing too serious. Split systems can work on either gas or electric power sources which makes them a great choice for those living in areas where brownouts and blackouts are common.


Q: How do I use a window air conditioner?

A: Usually, window units are fairly easy to install. Just open the window, place the AC inside and close the window again – some units come with double-sided tape which you can use to stick them in place; make sure that all edges are properly sealed so no cool air escapes your room. Turn on both the AC and fan (if it has one) and adjust settings until you achieve maximum efficiency.

Q: Where should I place my AC?

A: Window units work best when placed near a wall but not too close – if they’re too close they’ll suck in dust from outside, if they’re too far you won’t be able to cool the room efficiently. Most window units come with a built-in thermostat which helps you control their power level

Q: Do Window Units save money?

A: Yes – but only if you pick the right one. You have to remember that they’re less powerful than split systems so they won’t cool as much space as an AC with a stronger cooling system will – this means choosing the correct size and type unit. Find out more about this on our blog.

Q: Can I use a window unit in the winter?

A: The short answer is no – they were designed to cool during hot summer days, not cold winter nights. While some users report that this worked for them, you should only try it if you have no other alternatives – otherwise your room will get colder than expected and your AC won’t be able to warm it up again.

Q: Should I get a portable or fixed air conditioner?

A: The main difference between these two types is the installation process – the former can be installed almost anywhere while the latter needs to be placed near an open window. However, there are portable units which require permanent installation so take that into account when making sure – also, if you want to move house a lot, a portable unit might be the best choice.

Q: Can I use a window air conditioner in my bedroom?

A: Window units are designed for small rooms – if your bedroom is too large they won’t be able to cool it down properly. If you already have one of these units and need to cool a large space consider getting another unit which suits your needs better – otherwise make sure that there is nothing between you and the AC during cooling (towels or furniture). Also, try not to open windows or blinds as this will interrupt the airflow.

Q: How long do I have to wait before an air conditioner starts cooling my home?

A: Usually, both window and split systems will start cooling within minutes of being turned on – but this depends on the weather condition outdoors. If it’s hot outside you’ll have to wait a bit longer for your AC to work its magic.

How are Window Air Conditioners Better Than Split Systems?

They’re easier to install – most of them come with built-in installation features that make the process simple They’re cheaper than split systems Of course, if you don’t care about money, go ahead and get yourself a split system! But if all you want is cold air without spending too much money, window units are generally better options. You can easily upgrade by getting another window unit later on if necessary Portable units are great for those looking for temporary cooling solutions – especially if you have to move from place to place regularly. However, they have a limited cooling capacity so make sure that your room isn’t too large

How to Save Money on Your Air Conditioner?

Try not to rely on AC for all of your cooling needs – open the windows sometimes and let the fresh air in If software is not an option, try hardware – install double-paned windows or other solutions which decrease heat loss through walls Call your utility provider before you need repairs – most companies offer discounts for those who allow them to check their units regularly You can save energy by getting a programmable thermostat – these will help you set temperatures according to the current weather outside. Don’t forget about saving energy when choosing size as well – larger units will cost slightly more to run but they also cool larger rooms so it’s always better to get one size up than down

How Much Do Window Air Conditioners Cost?

The price depends on the brand, cooling capacity and additional features. Decide what your needs are before looking for an AC unit – larger units are usually more expensive but some come with extra features which might interest you. If you’re on a budget try using coupons or discounts to lower the price even further and get one that fits all your requirements.

How can I Make My Window Air Conditioner More Effective?

If you want to use a window AC for more than cooling only, consider installing a dehumidifier or air purifiers – these will make the air in your room cleaner and healthier (especially important if you suffer from allergies) Replace old filters regularly – this is essential for getting rid of bad smells and improving efficiency Get an energy-efficient unit with a high EER rating according to Energy Star recommendations. This will not only save energy but it might also pay off in the long run Consider buying a portable model with a large capacity -if size isn’t a problem then you won’t have any problems cooling down your home

Air conditioners are usually pretty straightforward machines – but not everyone knows how to get the best out of them. While it’s impossible to explain every little detail about using ACs, these short answers should provide some useful insights for beginners.


Window air conditioners are good at what they do – keeping you cool when you need it. Their main advantage is that they can be quickly installed in most windows without any problems or the need for professional help, making them great for temporary solutions when you’re on vacation or away on business. If you need a unit that will cool your bedroom or office, window air units are definitely worth looking out for.

All the best 10 Best Window Air Conditioner listed in this article are high-quality products which should not disappoint anyone who’s willing to pay for them.
