W hile ACs might be the best solution to cool off when those dreaded heatwaves strike, one common complaint regarding their operation is how much noise they make. Luckily, not all products are created after the same mold, and some break the pattern when it comes to their decibel output.

Here, we will review and rank the best quiet window air conditioners money can buy. Therefore, if you’re searching for an AC that you can sleep in the same room with, the products you see here comply with your expectations. No more waking up with night sweats or having to take cold showers multiple times a day to make it through the heat because you will maintain thermal comfort without much hassle. And all this without having to stand through annoying buzzing sounds that won’t let you concentrate on anything else.

Sleep quality at 32 °C was the best, followed by that at 28 °C, while sleep quality at 36 °C and 38 °C was the worst. The significant effects of high temperatures on sleep quality were mainly reflected in sleep duration and shallow sleep. Temperature had significant effects on sleep calmness, difficulty in falling asleep, sleep satisfaction, and sleep adequateness. The effects of temperature on these four indicators were significant. High temperatures led to a decrease in body temperature and an increase of the average heart rate and respiratory rate. Thus, wakefulness increased and SWS decreased.

How to Help Your Window AC Work Better

Before we dive into the main topic, we first want to talk a bit about how you can improve your AC’s performance. Yes, there are certain maintenance-related tasks that you should routinely do to keep the unit up and running just as effectively as it did the first day you ran it. Here is what you should do:

  • Keep the air filter clean: The purpose of the air filter is to trap particles like dust and hair from the air that passes through the AC. Evidently, this means that at a point the filter is saturated because of the dirt it accumulates. When this happens and the filter clogs, the airflow, as well as the efficiency of the air conditioner drop. Therefore, you must routinely take the filter out and wash it to get rid of all the debris that has attached to it.
  • Clean the front grille: When dirt accumulates on this part of the AC, the airflow is affected since an obstacle will stand in its way. The principle is pretty easy – if less air gets into the unit, less air will be cooled and blown back into the room. Just remove the grille and soak it in soapy water, rinsing the dirt if needed with a scrubbing sponge.
  • Keep the coil fins straight: When the coils are bent, the airflow is restricted, so it won’t cool down the area as effectively. What you must do is straighten the external condenser fins and the internal evaporator coil fins using a specialty fin comb.
  • Use fans for air circulation: A big issue regarding cooling efficiency stands in the fact that the cold air is flown directly in front of the AC. If you set up a fan in the room where you install the window-mounted cooling system, you maximize the AC’s cooling effect since the cool air is circulated and pushed around the room. Your set temperature is reached faster, so running costs are reduced in the process too.
  • Clean the condenser: The condenser is exposed to debris like pollen, dust, and rain. When too much debris builds up on it, the window AC can’t blow as much cold air inside as it normally would. Use a vacuum, toothbrush, or hose the exterior of the AC to clean this part of the system.
  • Clean the evaporator coil: Remove the front grille and air filter to reach the coil. Try vacuuming it clean first, and if this doesn’t work, hose down the interior of the AC.
  • Insulate the windows: Use curtains and drapes to let as little heat as possible come through the windows and amp the cooling performance of the AC in the process. Obviously, you must also make sure that all windows in the room are shut whenever the air conditioning unit runs.
  • Close the door: Keep the door closed in the room where you set up the window AC to make sure that the cold air isn’t lost and that your preferred ambient temperature is reached and maintained easier.

Now that you have all the know-how you need related to AC maintenance to lend the occasional helping hand that the products need from time to time so that it guarantees a streamlined operation, we can go ahead and move on to our main topic. Without further ado, let’s see what are the top-tier products this market offers.

Do you have sliding or casement windows in the room where you need to set up the AC? Then you need a special kind of unit that’s designed for this specific type of installation. Check out the best casement window air conditioners that will help you keep a cool living environment regardless of how hot it gets outside.

If you are someone who enjoys getting the most for their money, you must take a look at this model. In its operation, it can provide either 18,000 BTUs of cooling power or 12,000 BTUs of heating, which implies that you can use it year-round as well. It can create optimal living conditions for areas that measure up to 1,000 square feet. Additionally, it can either be installed as a window AC or through the wall.

Check out other through the wall air conditioners if this is the type of setup you are in need of to compare your best options to each other and make an informed pick.

The 18,000 cooling BTUs of this Friedrich AC might be a bit too much for the space that you intend to use it in. If that’s the case, the manufacturer has other options that are equally qualitative when it comes to performance and features but cater to smaller areas. There’s the Friedrich Chill Series CP12G10B that is rated at 12,000 cooling BTUs and works for 550 sq. ft. spaces, and the Friedrich Chill 10,000 BTUs that is appropriate for 450 sq. ft. areas.

It features auto louvers that automatically oscillate left and right as the room cools down, which ensures even cooling from corner to corner. Some of its features are:

  • Auto-restart – In case of a blackout, it will automatically restart on the latest settings.
  • Purifier – The integrated washable filter removes contaminants like pollen, dust, and mold spores from the air.
  • Timer – The 24-hour timer lets you set it to operate exactly as you need it to and cut down on running costs.

It is compatible with windows ranging from 26.5” to 42” in width. The air movement capacity it boasts is 430 CFM, so you can see that it complies with cooling needs in large spaces. To keep you safe, it comes with EntryGard protection, the steel retaining wire securely fitting the chassis to the sleeve to prevent “kick-in” intrusion. Additionally, the heavy-duty side curtains reduce the exterior noise. Some of its design features are:

  • Dehumidifier – It can remove 5.5 pints per hour, which adds up to a total of 132 pints of moisture removed over 24 hours.
  • Modes – Choose between cool-only, fan-only, heating-only operating modes.
  • Energy-efficient – EER of 11.2.

As you can notice, it comes with a lot of convenience-enhancing features that you can benefit from. Furthermore, the MoneySaver mode cycles between operating modes to conserve energy and reduce operating costs without cooling effectiveness witnessing any drops.

Performance Test Feedback

It’s fairly easy to install, nothing out of the ordinary compared to any other window-mounted AC. However, it’s a bit heavy, so make sure that you have someone else help you handle it. It’s as quiet as advertised, you can go ahead and install it in the bedroom or office just fine. If you set it at the lowest speed, you’ll barely hear it. I didn’t have a chance to test its heating capabilities since I tested it in July, but I can say for sure that it doesn’t take long to reach and maintain the set temperature during heat waves. Another thing that impressed me while testing the Friedrich EP18G33B was the high dehumidification rate. Before running it, the humidity in the living room was at a constant 65%, and since I’ve been using it, it never passed the 50% threshold. Controlling the timer is as straightforward as it gets, and I really liked how responsive the remote is to my commands.

Alternative Silent Window ACs Worth Checking Out


For the making of this article, we considered a total of 47 products that we picked alongside a team of experts. While the 6 models that ended up in our top are the best of the best, no doubt, there are a few other models that we almost included thanks to their on-par performance but didn’t for similarity reasons, because they came from the same brand as some of our picks, or because we considered that their downsides might bother potential buyers a bit more.

We do encourage you to look into these alternative models too before you decide since their cooling efficiency complies with the highest demands and they stay quiet throughout their operation. Here is a brief description of the pros and cons of the alternative products that we recommend you check out before you make a purchase:

6 Best Rated Quietest Window Air Conditioners for Bedroom

#1. Emerson Quiet Kool EARC15RE1



Emerson Quiet Kool ACs are known for their silent operation. When it comes to the EARC15RE1, the fact that it produces only 52 decibels makes it one of the quietest window AC systems available to date. In terms of performance, thanks to its 15,000 BTU cooling capacity, this model is perfect for cooling areas of up to 700 square feet. So yes, it is a large coverage product that you can count on for the trickiest of cooling demands.

It even integrates a 24-hour timer that doesn’t only give you full control over the unit’s operation but also helps save on running costs. Best of all, thanks to the two air exhaust vents and three fan speeds that it features, you can fully customize the direction in which the cool air flows, as well as the speed at which it blows into the room.

Why we chose to leave it out: The sliding insulation isn’t pre-installed, so you have to do a bit of manual work when you set up this AC. It’s nothing that you can’t handle or requires extensive knowledge, but rather a mere inconvenience that you don’t encounter with other models.

#2. Tosot Tranquility 8,000 BTU



This is an Energy Star certified product on which you can count to keep the room cool without drawing much power in the process. In fact, this 12 EER rated product is estimated to cost only $65 per year to run, which is considerably less than what you spend with most competitive models. Since it is rated at 8,000 cooling BTUs, it will provide optimal performance in spaces no larger than 350 square feet. But what impresses most, however, is the extra-silent operation. Depending on the fan speed you pick, it will produce from 42 to 49 decibels. That’s right, it stays quiet even on the highest operating setting, so you can go ahead and run it while you sleep without worrying that it might wake you up.

Why we chose to leave it out: You don’t have full control over the AC via the control panel; some settings and functions aren’t available with it. This is only provided by the remote control. Therefore, you have to make sure that the remote is always stocked up on batteries.

#3. Friedrich Chill Series CP12G10B


Check Price at Amazon
To benefit from optimal performance on this AC’s part, you ought to use it in areas no larger than 550 square feet. What makes it best suited for this scenario is the 12,000 BTU cooling capacity. When used as recommended by the manufacturer, you will also be pleasantly surprised to see that it can remove quite a considerable amount of moisture from the air too, namely 3.3 pints per hour. In short, you won’t need to turn on the dehumidifier in the room where this air conditioner runs regardless of how damp the air gets. It’s a budget-smart pick by default thanks to its energy-efficient operation. But you can still take things to the next level if you want to spend as little as possible on running it by operating the unit in the specialized Money Saver mode. Best of all, this model is suited for window or through-the-wall installation, so you have your pick when it comes to setup.

Why we chose to leave it out: We decided to include the Friedrich EP18G33B in our top instead since it covers wider areas thanks to its superior cooling capacity. This doesn’t reflect poorly on the CP12G10B, it simply implies that this alternative model is suited for smaller spaces.

#4. Friedrich Chill 10,000 BTUs


Check Price at Amazon
This Friedrich product guarantees even air distribution throughout the room thanks to the automatic air sweep louvers it integrates. It’s a budget-friendly option that provides optimal performance in spaces of approximately 450 square feet thanks to the 10,000 BTUs cooling output. What adds to the appeal of this product is the 11.3 energy efficiency ratio that indicates a low running cost of only $79 per year. It features an on/off timer that also helps save on operating costs. You can set it for 24 hours tops, providing you full control over the operation of the AC. The filter of this unit is washable and reusable, saving you money on maintenance thanks to this aspect. Another plus is that all the installation hardware is included in the package, so you won’t have to spend an extra cent to set it up.

Why we chose to leave it out: As with the CP12G10B that we previously talked about, there is nothing wrong with this 10,000 BTU model. It is simply suited for smaller spaces compared to our top pick, the Friedrich EP18G33B. If you want to go for a Friedrich AC, pick the model that provides the cooling capacity and area coverage appropriate for your situation.

#5. LG LW6017R


Check Price at Amazon
If you need a cooling solution for a medium-sized room, look no further than the LW6017R. This model is rated at 6,000 cooling BTUs, so you can count on it for rooms and spaces of up to 260 square feet. It’s as intuitive to use as it gets thanks to the user-friendly electronic controls and included remote control. On the lowest of its 3 running speeds, it produces 52 decibels. It might not be the quietest model we reviewed, but it’s still a viable option for bedroom use since it doesn’t make considerable noise. We like that it automatically restarts with your pre-selected settings after a power outage since it spares you from having to reinsert your preferred operational options. Best of all, to guarantee an energy-efficiency operation, it comes with a 24-hour timer, as well as the Energy Saver function.

Why we chose to leave it out: Since the area coverage of the LW6017R is slightly smaller than that of the LG LW8016ER that ranks 3rd in our top, so is the moisture removal capacity and cooling efficiency. Nevertheless, this doesn’t take away from the performance of the LW6017R, it just makes it the right option for different scenarios.

#6. LG Dual Inverter LW1817IVSM



Easy to install and use, this dual inverter air conditioner from LG is worth every cent. It’s one of the heavy-duty models available, producing 18,000 BTUs of cooling power to keep large-sized spaces at the perfect temperature during torrid days. In fact, you can count on it to provide optimal performance when used in areas of up to 1,000 square feet. When used in Sleep mode, this model produces only 44 decibels. It just doesn’t get any quieter than this. However, aside from the whisper-quiet operation, we must highlight that it is a Wi-Fi compatible product. This makes it the go-to for people who seek a modern solution for their home since it allows you to control the unit over your smartphone from anywhere. Speaking of control, there are 4 fan and cooling speeds to pick from. If you don’t want customized cooling but rather want to let the AC switch between speeds depending on interior conditions to keep the temperature you select constant, you can use the Auto Cool mode.

Why we chose to leave it out: Although it has a much higher cooling capacity than the LG LW8016ER, it fares the same performance-wise as the Friedrich EP18G33B with the small exception that our top pick is slightly less noisy. The difference is almost imperceptible, however, which is why we recommend that you closely compare these two products and choose the one that fits your budgets and demands better.

#7. Frigidaire GHWQ123WC1



If you seek energy efficiency, this Frigidaire product is what you must go for since it has received the Energy Star Most Efficient award thanks to the fact that it consumes 46% less power than standard AC units. It’s Wi-Fi compatible, and if you install the Frigidaire app on your smartphone, you can control it remotely via your smart device. Talk about convenience, right? Of course, what likely interests you most is the noise output, and seeing how it produces only 41 dB, it’s as quiet as it gets. Run it even during sleep time and it won’t wake you up, that’s for sure. It features a washable and reusable air filter that traps dust from the air pulled in so that it won’t affect the air conditioner’s performance. When the time comes to clean this part, the unit lets you know via the useful Clean Filter alert.

Why we chose to leave it out: We included the Frigidaire FFRA0511R1 in our top instead of this alternative model from the same manufacturer because the GHWQ123WC1 costs considerably more. It does cover wider areas than our 6th ranked pick, but we considered including the more budget-friendly pick in our top in this case, and only leave the heftier AC as an alternative suggestion for those who need the extra cooling power.



How To Stay Cool in a Heatwave


Summer is great, the birds are chirping and the sun is up, but you are sweating. If you want to keep the heat under control, there are certain things that you must do and stay cool. If you are a girl, you can agree that it’s very difficult to keep makeup on or to find the right clothes. If you are a man, you want to keep sweat under control as much as you can. After all, sweat patches aren’t aesthetically pleasing and they stain your fresh clothes. In addition to this, it is very difficult to fall asleep when you cannot breathe because of the suffocating heat. This is why we have provided you here with some neat tips and tricks to keep cool on the hottest of days.

Keep the Sun Out

It’s common knowledge that you need to stay away from the sun and rays as much as you can. When you are outdoors, you should always wear a hat and sunglasses to keep your skin protected. You do not want to throw your life away because you enjoyed the sun too much. If you are indoors, however, you should apply this advice:

  • Blinds – If you go for the thick material blinds that can block the sun rays from penetrating, you can enjoy full protection, as well as a cooler environment indoors. These are very useful for people who find the sunrise annoying as they black out the room completely.
  • Curtains – The curtains should be closed at all times, especially if you live in hot states. Otherwise, you will be exposed to skin cancer risks even if you’re not outdoors.
  • Shade – We strongly advise that you get yourself in a shaded spot between 11 AM and 3 PM from March to October.

Eat Properly

If you eat large meals, your body will inevitably consume more energy so it will warm up as it works to process what you have ingested. This is why many people prefer to eat a lot of vegetables and fruits during the warm periods of the year. Because metabolic heat is needed to break down food, small portions will be able to keep you cooler. You should also keep hydrated because:

  • Sweating will cause dehydration.
  • Once dehydrated, you risk heat exhaustion or a heat stroke.
  • An ice-cold glass of water will bring the body’s temperature down.

Get Low

It has been scientifically proven that hot air rises in a room. This is why you need to get as low as possible to get yourself surrounded by cool air. Many people prefer to sleep on the floor rather than the bed as your mattress can keep you hotter in the summer. In addition to this, if this doesn’t sound pleasing to you, you can sleep downstairs in order to escape the heat.


Frequently Asked Questions

Is it cheaper to run a window air conditioner or central air?

Depending on usage, it costs an estimated $30 to $80 to run a window AC, while a central air conditioning system costs from $90 to $120. The cheaper of the two, both upfront and in terms of running costs in the window-mounted unit. However, if you need to install a window air conditioner in every room of the house, you are better off with central air since the overall costs will be lower in this specific situation.

Why does the AC keep running when switched off?

It’s important to mention that the fan is different than the compressor, but they work together as a team. If set on Auto Mode or Energy Saver Mode, the fan will turn on for a few minutes to check on the room’s temperature. If it hasn’t detected any changes, it will resume its scan minutes later.

How much electricity does a window air conditioner use?

The majority of our picks are energy-efficient, so you don’t have to worry about high payments towards your electricity bill. Nonetheless, a medium-sized AC will consume around 900 watts per hour of continuous use.

How do I clean the air conditioner?

Monthly, use a vacuum hose to remove any dust and dirt in the front grill. If the unit has a washable filter, remove the filter and use a damp cloth to remove any grime. Ensure that it’s dried completely before you place it back into the unit.

How do you clean mold out of a window AC?

First, you have to get the AC out of the window and place it on the floor or a flat surface that can support its weight. Then, remove the grille and the air filter. Proceed to clean the filter as instructed in the manual (usually, soaking it in hot soapy water that is mixed with half a cup of bleach should do the trick). Take the AC apart by removing the top and back of the cabinet. Make sure that you vacuum any debris inside the AC well. Get a specialized coil cleaner and use it on the coils to clean them. Wash the cleaner off, and let the parts air dry. Wipe the inside surfaces of the AC with a scrubbing sponge that you dip in a mixture that is part hot water and part household bleach (about half a cup of bleach for a bucket of a few gallons of water). Remove all debris from the filter by spraying it with water once more. When all the parts have dried, just put the system back together and you can safely go ahead and use it.

Is it safe to leave the window AC on all day?

It’s not safe for the environment to run the AC 24/7 since the hydrofluorocarbons used by the system to lower the temperature indoors are among the main contributors to global warming. There’s also the possibility that something might eventually malfunction, and if you’re not around to turn the AC off, this could spell disaster. It’s better to just program the timer (if the AC features one) to turn off after a few hours, let the system “rest” for a while, and then turn it back on when it’s needed.

Can I run a window air conditioner during winter?

Running the AC when the weather outside drops dangerously low is a bad idea because the oil that lubricates the compressor becomes thicker and won’t provide the needed lubrication. Most manufacturers disclaim in the accompanying manuals the minimum temperature at which it is safe to operate their ACs, so make sure that you check out this detail. With most units, it’s recommended that you don’t run the AC when the temperature is lower than 65 degrees Fahrenheit for more than a few days.

What temperature should I set the AC at during the night?

To create comfortable sleeping conditions, you should set the AC to keep the temperature at a level ranging from 60 to 67 degrees Fahrenheit. This way, you won’t wake up because of night sweats and you will find it significantly easier to fall asleep since you finally enjoy proper thermal comfort.


Conclusion

If you’re looking for an AC that will take care of the room’s comfort levels as you’re sleeping, all of the models mentioned will take care of your needs. Moreover, all of them provide more than just cooling as their multiple operating modes ensure that you are provided with air circulation and dehumidification as well so that you get the most for your money.

Best Quiet Window Air Conditioner for Sale: Friedrich EP18G33B

What makes it the best isn’t only that it can upkeep quietness as it runs regardless of the speed setting you select, but that it provides year-round use as it employs 18,000 BTUs of cooling power to keep the indoor space nice and chilly as you like it when summer comes and there seems to be no hiding from the sun’s heat, and 12,000 BTUs for heating when winter comes and you seek a cozy spot to warm up.

Moreover, it completely eliminates the need for a dehumidifier as it actually wicks an estimated 132 PPD from the air, so you end up saving a lot of money as it substitutes a different appliance you would normally need to install.

Editor’s Choice: LW8016ER

LG is a well-established name, so it comes as no surprise that the value deal in terms of quiet ACs comes from this electronics company. With a 12.1 EER and providing you the ability to program after how many hours it should stop operating to save on running costs, it doesn’t only cost a reasonable sum of money upfront, but it doesn’t stack up the electric bills irrespective of how much you run it either. Just make sure that you utilize it in a space of 340 square feet tops as, in any room or space larger in size than this, it will inevitably underperform.

Best Quiet Window Air Conditioner for Year-Round Use: Koldfront WAC12001W

What makes it appropriate for year-round use, you ask? Well, it’s simple. Seeing how it provides 12,000 BTUs of cooling power, as well as 11,000 BTUs of 3,500-watt heating functionality, you can use the Koldfront AC regardless of the season to establish thermal comfort as, during summer it can make the space feel cooler, while in winter, it will warm up the place so that you sit comfy without having to get wrapped in multiple blankets. It even wicks approximately 2.5 pints of dampness from the air per hour, which aids in thermal comfort as humidity plays a role in ambient conditions as well.
