I Tested And Reviewed 10 Best Energy Efficient Window Air Conditioner (2023)

I recently purchased the GE 5000btu air conditioner to replace my previous unit in my attic-turned-model train room. I must say, I am extremely satisfied with this purchase. Firstly, the size of the unit is surprisingly compact and not bulky at all, which is a definite plus for me. It fits perfectly in my window without obstructing the view.

In terms of performance, this air conditioner is a little powerhouse. Despite being rated at 5000btu, it performs just as well, if not better, than my previous 6000btu unit. It effectively cools my 8'x16' room and does an excellent job of pushing the air out. I suspect that it may actually be underrated by GE and could potentially be a 6000btu unit.

Additionally, the noise level of this air conditioner is impressively low. It operates quietly, allowing me to enjoy my model trains without any disturbances. The package and delivery of the unit were also satisfactory, further adding to my positive experience.

The only minor drawback I have encountered is the inability to adjust the direction of the air flow up or down. While I can adjust it left to right, I would have liked the option to tilt the air flow upwards in my tall window. However, this is a minor inconvenience compared to the overall performance of the unit.

I would also like to mention that the initial cooling effect of this air conditioner is remarkable. Even when I initially turned on just the fan mode, it was able to cool the room by a couple of degrees by pulling out the hot air and blowing it back out cooler. Once I turned on the AC unit, the room cooled down quickly, and I even forgot to turn it off one night, resulting in a freezing cold room the next morning.

I am extremely satisfied with my recent purchase of this unit. I recently moved into a new home and needed a unit to cool the entire downstairs area, which consists of multiple rooms including the living room, kitchen, dining room, and a walkway hall. I was skeptical at first, but this unit has exceeded my expectations by effectively cooling the entire space. I am very impressed with its performance.

Additionally, this unit fits perfectly in my small NYC apartment window. Despite the limited space, it cools my relatively large room very quickly. The smart app feature is also a great convenience as I can easily control the AC from my phone, ensuring that my room is cool by the time I arrive home from the subway. The setup process for the app was a breeze, taking me only about 10 minutes.

As someone who recently relocated from Texas with central AC to the Adirondacks without any AC, I can confidently say that this unit has been a lifesaver. Though the area may be cooler, my house still gets hot, especially upstairs. Installing this window unit in my bedroom has made a significant difference in keeping the room cool. I jokingly say that I may stay in my bedroom until September because of how well it works. The only minor inconvenience was having to trim a small lip on the window trim to ensure a proper fit. The unit does not come with external support, so additional support may be necessary for stability. Despite these minor issues, the functionality of the unit outweighs any aesthetic concerns.

My house is particularly challenging due to direct sun exposure all day, which causes my west-facing windows to radiate heat into the interior. Since I have not been able to upgrade to central air in my older home, this 14,000 BTU unit has been a game-changer. I have a small portable unit in my bedroom and this larger unit in my living room, and together they effectively cool my entire 1275 sq ft house. The airflow from the unit reaches my kitchen, guest bedroom, and bathroom, in addition to the main living area. Although the volume on my TV needs to be turned up when the unit is running, it is significantly quieter than my portable unit and the wall unit I previously had in my apartment.

The installation process for this unit was a two-person job due to its weight, but it securely fits in my window and can be powered by a standard outlet, which is a huge plus. The WiFi functionality works seamlessly and was easy to set up. The only minor setback was that the remote stopped working after a week, but I suspect it simply needs new batteries. It is not a major concern for me. The only improvement I would suggest is the addition of adjustable front louvres to allow for directing the air flow. Currently, the unit blows cold air directly at my sofa, requiring me to cover up with a blanket if I am sitting on the couch while the unit is running.

In terms of energy efficiency, I am pleased with the results. Despite running the bedroom unit and a fan alongside this unit, my electric bill only increased by around $10. This demonstrates the efficiency of the unit. Overall, I am highly satisfied with this brand and would definitely purchase from them again. This unit has been a fantastic addition to my home, and I cannot recommend it enough.

The remote control provided with this air conditioner is not very useful and it came bent in half for some customers. However, since it only has basic functions like turning the A/C on and off, it is not a major issue for most users. The unit itself performs well in terms of cooling. At 75 degrees on the low cool setting, it effectively cools the living room, dining room, and kitchen without making it frigid. It is likely that lowering the temperature further would result in even colder temperatures. Additionally, the unit does not consume a lot of power, which is a positive aspect. The installation process is also hassle-free and quick, with no leftover parts. Compared to other air conditioners with similar BTUs, this unit is relatively small in size.

In terms of noise, this air conditioner is remarkably quiet, making it suitable for use in an office setting. It effectively cools a 10 ft by 21 ft room with a vaulted ceiling, even on the low setting. This is a great advantage for those who need a cool working environment. The remote control does not come with a battery, but considering the overall satisfaction with the unit, purchasing a separate battery for it is a small inconvenience.

For customers with larger areas to cool, such as a living room, hallway, kitchen, and bathroom, this air conditioner may not be sufficient. While it effectively cools the living room, it requires programming to maintain a temperature in the 70s. The presence of blackout curtains also helps to prevent sunlight from heating up the room. However, the remote control does not function properly, which can be frustrating. It is important to thoroughly check the remote control upon receiving the air conditioner to ensure it is in working condition. Additionally, this air conditioner is quite heavy, which may pose challenges during installation.

One satisfied customer had previously used a 10,000 BTU portable air conditioner in a 200 sq ft bedroom. After switching to this unit, they realized the previous one was low on coolant. The new air conditioner effectively cools the room and allows for a temperature range of 62-65 degrees, providing a comfortable sleeping environment. The remote control works well, adding convenience to the overall experience.

Considering the mixed reviews regarding the remote control and the need for proper inspection upon delivery, this air conditioner offers satisfactory cooling performance for smaller spaces. However, for larger areas, it may not be as effective. The quiet operation and efficient cooling make it suitable for office use, while the heavy weight may pose challenges during installation. Overall, it is a reliable option for those seeking a cool and comfortable environment.

The GE Profile Ultra Quiet Window Air Conditioner is a game-changer when it comes to providing a calm and peaceful environment. Unlike other units that produce loud and disruptive noises, this air conditioner operates quietly, making it ideal for bedrooms and small spaces. The previous unit the reviewer owned had been a constant source of annoyance with its window-rattling roars, but with this GE unit, they can finally enjoy a good night's sleep without any disturbances. The ability to turn off the indicator lights adds an extra level of convenience, allowing for a cool, quiet, and dark sleeping environment.

One noticeable difference with this air conditioner is its weight. Weighing 65 pounds, it is substantially heavier than other units in the same BTU range. Additionally, the GE Profile Ultra Quiet Window Air Conditioner comes at a slightly higher price compared to other models with similar cooling capabilities. However, the main feature that sets this unit apart is its exceptional quiet operation, with a listed noise level of 42dB compared to the average 55dB of other units. The reviewer's skepticism was quickly dispelled as they found the unit to be both powerful and remarkably quiet, making it a worthwhile investment for a peaceful night's sleep. It's important to note that due to its weight, assistance may be required during installation.

Another reviewer shares a similar experience, expressing their satisfaction with the quietness of the unit. They had previously owned a noisy AC unit and were delighted to find a similar GE unit that provided excellent cooling performance while being extremely quiet. Although this unit may be a bit pricey and heavy, the reviewer believes it is well worth the cost, emphasizing the importance of purchasing it before it becomes discontinued.

In a larger open space, this air conditioner proves to be efficient in maintaining a comfortable temperature. With a tall fan strategically placed near the unit, the cool air is able to circulate throughout the living room, dining room, and kitchen, keeping the entire space cool even in hot weather. The reviewer also mentions their dislike for the Eco mode, but clarifies that this is a personal preference and not specific to this particular machine. Fortunately, the Eco mode is optional, allowing users to customize their cooling experience according to their own preferences.

The GE Ultra Quiet Air Conditioner is a game-changer for anyone seeking a quieter cooling solution. I recently moved my bedroom TV to the other side of the room, which happened to be my son's room. With the arrival of hot weather, I installed my old AC in the window and quickly realized that its loud noise was a problem. Raising the TV volume meant risking waking up my son at night, which was far from ideal.

In search of a quieter alternative, I explored various options, including U-shaped air conditioners that require a support bracket. Unfortunately, my room's location on the second floor above the porch and the limited space below the outside window sill made it impossible to install such a unit properly. However, my research led me to the GE Ultra Quiet Air Conditioner, and I am extremely glad I gave it a try.

First and foremost, this AC unit lives up to its name. It is RIDICULOUSLY QUIET! To confirm this, I used a decibel app on my phone and measured the noise level from three feet away. It consistently registered under 40db, which is impressively quiet. The design of the unit is also well thought out. The slanted vents ensure that the air blows upward instead of directly at you. This feature is particularly appreciated by those, like me, who prefer not to have cold air blowing directly on them.

Installation was a breeze, although I must note that the unit is relatively heavy for its size. Despite this, it protrudes about eight inches past the window sill, which gives it a sleek appearance. Moreover, this air conditioner has an added bonus – it is a smart device. It connects to your smartphone and is also voice-controlled through Alexa and Google. Although the voice control feature may have a few minor issues that could be resolved, I personally find it convenient enough to use the remote or the app.

Speaking of the app, it offers a useful feature that tracks and displays the power consumption of the unit on a daily basis. This provides valuable insight into its energy usage and allows for better control over electricity costs. With all these exceptional features, I can confidently say that this AC unit is worth every penny.

I recently purchased this air conditioner and I must say, I am extremely satisfied with my purchase. The setup process was a breeze, and I was able to get it up and running in no time. The unit itself works like a charm, providing a steady stream of cool air that quickly cools down the room.

One of the standout features of this air conditioner is the multitude of settings it offers. Whether I want to adjust the temperature, fan speed, or mode, there are plenty of options to choose from. This allows me to customize my cooling experience to suit my preferences perfectly.

Speaking of cooling, this air conditioner does a fantastic job at keeping my bedroom comfortable. Even though my bedroom is 12×15', the unit is able to cool it down efficiently and effectively. I no longer have to worry about restless nights due to the heat, as this air conditioner keeps the temperature just right.

One aspect that I particularly love about this air conditioner is the remote control. It allows me to conveniently adjust the settings without having to get up from my bed or desk. This makes it incredibly convenient and adds an extra level of comfort to my experience.

Additionally, I am impressed by how quiet this air conditioner is. Even when it's running at full blast, it doesn't produce any distracting or annoying noises. This is especially important when it comes to using it in my bedroom, as I can enjoy cool air without any disturbances.

I recently purchased the Freo 8,000 BTU Window Air Conditioner and I must say, it is the best air conditioner I have ever owned. From the moment I received it, I was impressed with its sleek and powerful design. Installing the unit was a breeze, with clear instructions and all the necessary parts included. While it is manageable to install alone, I would recommend having an extra set of hands to help with lifting it into the window.

One of the standout features of this air conditioner is its quiet operation. Even when running at full power, the noise level is minimal, allowing me to enjoy a cool and comfortable environment without any disturbances. The ability to adjust the air flow is another great feature, providing me with the flexibility to direct the cool air exactly where I need it.

In terms of aesthetics, the Freo 8,000 BTU Window Air Conditioner is a winner. Its modern honeycomb pattern vent adds a touch of sophistication to my home decor, blending in seamlessly with its surroundings. Unlike other AC units that can be an eyesore, this one looks sleek and shiny in the window.

I must also mention the impressive cooling capabilities of this unit. It is incredibly powerful and can cool a large area within minutes. In fact, it has made such a difference in my living room that I am considering purchasing two more for other areas of my home. The cold air it produces is comparable to central air, making it a dream come true for those of us without that luxury.

While I cannot speak to its energy efficiency, as I have not had it long enough to assess, I can confidently say that the Freo 8,000 BTU Window Air Conditioner is worth every penny. Its reasonable price, combined with its exceptional performance and attractive design, makes it an amazing AC unit. If you are in need of a reliable and powerful air conditioner, I highly recommend giving this one a try. You won't be disappointed.

I am extremely satisfied with this air conditioning unit. One feature that I absolutely love is the remote control. It allows me to easily adjust the settings from anywhere in the room. Speaking of settings, this unit offers a wide range of options, providing me with the perfect level of cooling for my needs.

The noise level of this air conditioner is also worth mentioning. While it is not completely silent, it is not overly loud either. This makes it ideal for individuals who wear hearing aids, as it does not interfere with their hearing experience.

I initially had concerns about the size of the unit, but the return process was hassle-free and the company accepted my request without any questions. However, I ended up deciding to keep it because it works so well.

One of the standout features of this air conditioner is the ability to turn off the display at night. This is a great feature for light sleepers like myself, as it eliminates any unnecessary light that may disturb my sleep. Additionally, the timer feature allows me to have a comfortable room temperature when I arrive home, as it automatically turns on before I get there.

I purchased this unit to replace a smaller air conditioner and I am extremely satisfied with its performance. The new 10000 BTU capacity is more than enough to cool my room, and I have not encountered any issues thus far. The app feature is a nice addition, as it provides me with useful information such as the current temperature, set temperature, and energy usage.

The only minor drawback I experienced was that the unit's dimensions did not match the description when the legs were attached. However, this was easily resolved by finding a workaround. Other than that, everything about this air conditioning unit is fantastic. The remote control, app, and unit itself work seamlessly together, providing a great user experience.

I recently purchased two Midea U-shaped air conditioning units (12k and 8k BTU) as a temporary solution while preparing for a furnace upgrade and heat pump installation. While I acknowledge some flaws, I am generally forgiving due to the temporary nature of their use.

Let's start with the negatives. Some reviewers have mentioned the installation process, and I can confirm that it is not as easy as depicted in the videos. I would advise budgeting at least an hour to ensure proper installation. Additionally, the bracket that holds the unit rests on the edge of my screen frame instead of across the top of the track, which may leave a mark. However, this is a minor issue that can be easily overlooked. I also noticed a gap in the front of the bracket, allowing air to enter. To address this, I used the included insulation tape to cover it. Furthermore, the bracket's front appearance is not as sleek as the rest of the unit, with its multiple adjustment holes.

The anti-tip L-shaped arms and extendable window track arms did not fit my window perfectly, causing the units to sit slightly forward. This was necessary to accommodate the lift bar on the bottom edge of the window. Consequently, both units rest on their brackets and are held in place by the window resting in the U-shape.

In terms of connectivity, setting up Wi-Fi with the Midea Air app was relatively easy. However, I have been unable to get it to work with Alexa. Determining the cause of this issue is challenging due to the subpar Alexa app.

One disappointment is the use of Styrofoam as a packing material. Given the current environmental concerns, I believe alternative options should be explored.

On the positive side, the Midea U-shaped AC units are undeniably gorgeous. Their sleek design, reminiscent of Apple products, is likely what attracted you to them in the first place. The U-shaped design effectively separates the noisy components outside while keeping the stylish part inside.

I must commend the included foam, which can be configured in numerous ways. It is far superior to the accordion flaps found in other window AC units. With some time spent playing around and cutting the foam to fit your windows, it effectively blocks out air and heat. The units deliver cold air as expected, effectively cooling the main floor of my 750 square foot home. The louver can be adjusted up and down to circulate the cold air.

The inverter technology is another noteworthy feature, as it spools the compressor up and down rather than turning it off and on. This not only reduces noise but also minimizes energy consumption. The accompanying app works well, eliminating the need for an additional remote control. The design also allows for ample light to enter the room, and the window can be easily opened.

Safety measures are also taken into account, with tabs inside the U-shape preventing people from opening the window.

One of the most impressive aspects of the Midea U-shaped AC units is their quiet operation. They emit a noise level comparable to that of a cylindrical tower fan, making them ideal for any setting.

A few additional notes: the power cord is located on the right side of the unit when viewed from the inside, so it's important to plan accordingly. Upon initial startup, both of my units rattled for a short period (approximately 5-10 minutes), but the noise disappeared as the machines warmed up. It's worth mentioning that the weight of the units is distributed towards the rear, so lifting them alone may be challenging. Enlisting the help of a friend or partner is advisable.

When comparing the Midea U-shaped units to their competitors, I found that LG offers high-end window AC units with inverters, smart features, and sleek designs. However, the Mideas surpass them in terms of price and design innovation. Additionally, certain LG models were too large for my windows due to the age of my home. While Soleus offers a saddle AC unit with a unique design that allows more light in and simplifies installation, it lacks an inverter, smart features, app/Alexa integration, and its industrial design may not appeal to everyone.

Other reputable brands such as GE, Frigidaire, and Toshiba also have great units, but they tend to be noisier and lack smart features or inverters. Portable units, resembling R2D2, are noisier, less efficient, and have the drawback of warm exhaust air inside the house. Mini splits are a viable alternative, but they come with a higher price tag for professional installation in my area (Seattle), and DIY kits are not significantly more affordable. Heat pumps and central air systems require substantial investment ranging from $7000 to $15000, making them a major consideration for future upgrades.

I am extremely satisfied with my recent purchase of this unit. I recently moved into a new home and needed a cooling solution for the downstairs area, which consists of multiple rooms including the living room, kitchen, dining room, walkway hall, and a bathroom. I was initially skeptical about whether this unit would be able to cool the entire space, but it has exceeded my expectations. It effectively cools the entire downstairs area, and I am very impressed with its performance. In fact, I am so pleased with it that I plan on posting a video showcasing the area it cools.

Additionally, this unit fits perfectly in my small apartment window in New York City. Despite having a relatively large room compared to New York standards (18X10), my previous 6,000 BTU unit was not sufficient in cooling the space. However, this unit cools my room very quickly, and I am amazed at how efficient it is. I particularly appreciate the smart app feature, which allows me to control the AC from my phone. This way, I can ensure that my room is cool by the time I arrive home from the subway.

I want to address a correction I made in my previous review. I initially mentioned that the front louvres were not adjustable, but upon closer inspection, I realized that they are indeed adjustable. This unit is truly great, and I am very satisfied with its overall performance.

My house tends to get extremely hot due to direct sun exposure throughout the day, especially during the hot late afternoon and evenings. Although my house does not have central air conditioning, this unit has been a lifesaver. I have a small portable unit in my bedroom, and this 14,000 BTU unit in my living room. Together, they effectively cool my entire house, which has a total area of 1275 square feet. The cool air from this unit reaches not only the main living area but also the kitchen, guest bedroom, and bathroom. Although the unit does produce some noise when it kicks on, it is much quieter compared to my previous portable unit and wall unit. The only inconvenience I have experienced is that the air blows directly at my sofa, requiring me to cover up with a blanket if I am sitting on the couch while the unit is running.

Installation of this unit was a bit challenging due to its weight of around 80 pounds. It definitely requires two people to install it securely in the window. However, once installed, it sits securely and does not cause any concerns. I appreciate that this unit can run on a standard outlet, as it was one of the only larger-sized units I could find with this feature. The WiFi connectivity works flawlessly, and setting it up was a breeze. Although the remote stopped working after a week, I believe it may just need new batteries, so I am not particularly worried about it.

In terms of energy efficiency, I have noticed a minimal increase of around $10 in my electric bill since using this unit along with my bedroom unit and a fan. Considering the size and cooling capacity of this unit, I find it to be quite efficient. Overall, I am highly satisfied with this brand and would definitely purchase from them again. This unit has been a game-changer for me, and I absolutely love it.
