Buying Guide: How to Choose the Best Window Air Conditioner

Energy Star Rating

best window air conditioner brands

Since October 2015, all Energy Star-rated window AC units meet the Energy Star 4 standard that sets the units’ power use at 10% less than older models.

Old models with a low energy efficiency rating are cheaper, but they drive up energy bills and are costly to maintain.

Meanwhile, relatively newer models with an EER rating of 10 or more are expensive, but they are energy efficient and hardly need costly maintenance, making them an investment.

Cooling Capacity (BTU)

best window air conditioner brands

The cooling capacity of an AC is measured in BTU and depends on the room’s size. For every square foot of space that you want to cool, you should ideally go for 20 BTU.

You might be tempted to get an AC with a higher BTU for a small space, but that might be counterproductive. Yes, it will cool down your room quickly, but it won’t get rid of the humidity. An AC with a lower BTU will take more time to cool down the room, but it will also take care of the humidity.

Meanwhile, a low BTU AC in a big room will just be a waste of energy.

Coverage Area

We advise you to measure the window size and estimate the square footage of the space or room you want to install the AC in so that you choose the right option.

Here’s a chart with a rough estimate of the BTUs you need depending on your room’s size.

Room size

BTU

100-150 square feet

5,000

150-250 square feet

6,200

250-300 square feet

7,000

300-350 square feet

8,000

350-400 square feet

9,000

400-450 square feet

10,000

450-550 square feet

12,000

550-700 square feet

14,000

700-1000 square feet

18,000

1000-1200 square feet

21,000

1200-1500 square feet

24,000

1500-2000 square feet

30,000

2000-2500 square feet

35,000

Remember, this table is only a rough estimate and assumes only 2 occupants. Add in 600 BTU of cooling power for each additional person.

When sizing the window AC, there are a few other things you should consider.

For instance, if your room gets direct sunlight, it’s better to increase the BTUs by 10%. Similarly, reduce the AC’s capacity by 10% for heavily shaded parts of the house.

And if the AC will cool a kitchen, make sure to add 4000 BTUs to the capacity.

Refrigerant (R410A or R32)

Since 2006, the majority of new AC units use the R-410A refrigerant instead of the ozone-depleting R22 refrigerant.

Today, R32 is also available.

R-410A doesn’t damage the ozone layer, and it has a global warming potential of 2088. R32 also doesn’t damage the ozone layer, but it has a much lower global warming potential of 675.

In comparison to R-410A, R32 also improves energy efficiency by up to 10%.

And while AC units that use R32 are relatively more expensive, they have roughly one-third the environmental impact of units with R410A.

Window Type

Window type is another important consideration.

Windows can usually be divided into 3 categories:

The installation kit you get with most air conditioners works with both standard and slider windows. But if you plan to install an AC on a casement window, look for a unit that is compatible with that window style.

Warranty & Durability

Before you finalize your purchase, check for the warranty that the manufacturer offers. Keeping in mind that your AC is going to serve you for 8-10 years, it’s better to opt for an extended warranty to minimize the risk of unforeseen expenses. 

A long warranty also means that the manufacturer trusts its unit to work well for years without causing any problems. So, you can know how durable the unit is by checking out the unit’s warranty coverage.

Another way to ensure durability is to check out what other verified users have to say about the AC.   

Price

best rated window ac

The price of window air conditioners depends on their cooling capacity and the area they cover.

Small AC with a 5000-6500 BTU capacity cost roughly $180 to $350 and cover around 100-300 square feet.

Medium-capacity air conditioners with a BTU rating of 7000-8200 cost anywhere between $250 and $400 and can cover up to 400 square feet.

Large-capacity air conditioners range from 9800 BTU to 12500 BTU and cost around $350 to $600.

Low Maintenance

Window AC are usually low maintenance. Servicing them is also quite simple since all the components are compactly designed.

You can check if your AC is also low maintenance by looking at what verified users have to say about its maintenance.

Remote Control

A remote controller lets you adjust the settings and control the air conditioner (turn it on or off) even from across the room.

In some cases, the remote also works as a portable temperature sensor to make sure the room is evenly cooled. The remote activates the AC as soon as the air around it reaches a pre-specified temperature.

Adjustable Fan Speed

The fan speed lets you set the rate at which the device will cool down the room.

Cheaper air conditioners usually with 2 fan speeds, high and low, while high-end units feature 3-4 fan speeds (auto, high, medium, low).

Remember that the number of fan speeds that an AC has becomes less important the longer it operates. Once the room cools down, only the low setting is enough to maintain a cool, comfortable temperature.

The auto speed is a convenient option as it automatically adjusts the fan speed and maintains the right temperature. The auto mode is also energy efficient and helps save money.

Noise Level

best window air conditioner brands

While you can easily fix the sounds coming from Window AC, which primarily arise due to problems like a lack of lubrication on the motor, a loose front grill, vibrations from the window, and bent fan blades, you can’t really do much about a window AC making a lot of noise as long as it is turned on and running. 

Some window air conditioners are just annoying and loud. So, if you can’t handle some background noise, make sure you check the decibel level of the AC before buying it. This is especially important if you plan to install the AC in a quiet room like the library or your bedroom.

Some brands like Frigidaire, LG, and Friedrich pride themselves in manufacturing some of the most silent AC units.  

Air Direction Control

Most Window ACs blow air in one direction.

However, a window AC will serve you better if it directs air towards the center of the room.

So, before you make the purchase, check if your AC has adjustable louvers.

Programmable Thermostat

A thermostat allows you to control your AC’s output temperature.

Some budget models come with a mechanical thermostat that has a dial you rotate to set the desired room temperature. This dial has a few numbers for the coldness settings (like 1 to 5) instead of degrees.

But most high-end models come with a digital thermostat that is not only highly accurate but also keeps the temperature consistent. With a digital thermostat, you can select a specific degree setting.  

Programmable Timer

best window air conditioner brands

A programmable timer lets you plan how the air conditioner runs and when to turn it on and off. This way, you can conserve energy by shutting off the AC when no one is around.

And instead of leaving the air conditioner switched on throughout the day, you can even program it to turn on 30 minutes before you usually come back home.

Cheap models only have pre-set intervals, like 12, 8, 4, or 2 hours for when the AC should turn off, while more premium models allow you to program certain stop and start times throughout the day. In fact, you can even set up some 24 hours in advance.

Filter Alert System

Window AC usually have a filter alert system in the form of a digital notification or a light indicator. This system tells you when the filter needs cleaning.

A dirty filter lowers the AC’s efficiency as it makes the AC work hard, which is why it’s essential to clean it in time.

A clean filter also ensures cleaner indoor air, so make sure you opt for a model with a filter alert system.

Installation of Window Air Conditioners

The installation of window AC units depends on the type of window.

Almost all models are designed for double-hung windows that have vertical window sliders.

The sliding pane sits behind the bracket and provides a secure brace to prevent the AC from falling out of the window. Most AC units also come with expanding baffle wing curtains that make it easy to fill up the gaps on either side of the model.

The installation itself is quite easy and simple. Generally, most window sills support the AC and don’t require you to make any changes. Still, installation kits come with brackets or include tips to add bracing if your storm window keeps the AC from sitting well. 

Then, you just need to make sure that the included foam sealing is in place and attach the wings to fill the gaps.

Next comes the hardest part: hosting the AC in place, and it’s better if you have a helping hand. Rest the AC in the frame and ask a helper to steady it. Then, slide the inside window sash in its place to secure the air conditioner. 

After that, you only need to add stop-braces to ensure no one accidentally opens the window. Finally, use tape and insulating panels to close any remaining gaps so that the cold air doesn’t escape the room. 

In the case of a horizontal sliding window, you need a shelf or a brace against your exterior wall to secure the unit.

Installing an air conditioner on a casement window is the trickiest part, even though AC models designed for horizontal slides are usually also designed for casement windows.

For detailed installation instructions, make sure you check out the unit’s user manual. 

Why buy a Window AC over Central HVAC?

The most practical reason for buying a window AC instead of a central HVAC is, of course, the costs involved. It is much cheaper to purchase, install, and maintain a window AC compared to a central HVAC.

You can get a high-quality central HVAC system for roughly $1500, but when you factor in the installation, maintenance, and operation cost, the total can go as high as $10,000.

Meanwhile, you can easily get a window AC for around $2000 to $600 with monthly operating costs of around $30-$80, depending on your use.

Installing a window AC is pretty easy. You only need a window, and you can even install the unit yourself without professional help. All you need to do is follow the manufacturer’s instructions.

However, installing an HVAC system is costly and complex. You need to have a large budget to be able to install vents around the house (this can easily cost up to $5000).

Plus, modern window AC models work as heaters as well.

Cleaning and Maintenance of Window AC

best window air conditioner brands

Regular maintenance can keep your window AC efficient for years.

To maintain your unit regularly:

1. Clean or replace the filter as specified by the manufacturer.

Clean filters not only keep the AC efficient but also reduce dust.

You can extend the life of AC filters by vacuuming them or washing them with mild soap and water. Make sure they are completely dry before you install them.

Also, make sure you wipe the cabinet gently. Make sure you turn the unit off before doing any maintenance.

2. Store properly

If you plan to store the window AC for the winter season, make sure you follow the manufacturer’s instructions.

Final Verdict: What is the best Window AC brand sold today?

There are many top window AC brands with excellent models, making it difficult to choose one.

But names like LG, Haier, and Kenmore are household names you can trust.

So, before you opt for a brand, make sure you go through verified customer reviews and the brand’s warranty policy to make a sound investment.
