How We Found The Quietest ACs

Quietest Window Air Conditioners

One of the most frequent arguments you’ll encounter when talking about window ACs is that they’re noisy. People are reticent to use them because they believe that a window AC will disrupt daily activities such as talking on the phone or watching TV.

But after thorough research and testing, we believe we found the quietest window air conditioners on the market.

Here’s how we did it:

How A/C Sound Level Is Measured (Understanding Decibel Levels)

Like all sounds, the sound air conditioners produce is measured in decibels (dB). The first thing we did was to look for window air conditioners that come with a low decibel rating. The lower the decibel rating, the quieter a unit will be.

Now, according to their decibel ratings, the quietest air conditioners produce up to 50 – 60 dB. But what does that actually mean, what will you hear?

Well, here is a list to give you an idea

  • A normal whisper – 20 dB
  • The sound of a residential area or a quiet park – 40 dB
  • Quiet conversation – 50 dB
  • Speech levels during a restaurant conversation – 60 dB
  • The noise in a busy office – 70 dB
  • A working garbage disposal – 80 dB
  • Railway platform – 100 dB
  • Jet engine as it speeds down the runway – 140 dB

You might have noticed that the differences between a working garbage disposal and a quiet conversation are not that large. After all, since a whisper produces 20 dB, so much difference can 30 dB make?

Honestly, the actual difference might be more difficult to grasp. When it comes to decibels, the differences are not as linear as they seem.

For example, a quiet conversation produces 50 dB whereas the noise in a busy office has a rating of 70 dB. Believe it or not, but 50 dB actually represent one-fourth of the 70 dB value. 80 dB is 2 times louder than 70 dB, and 60 dB is only half of 70 dB, and so forth.

As far as regular air conditioners are concerned, their noisiest part is the compressor that’s placed outside the building. Window air conditioners don’t use a separate compressor, so they tend to be louder than regular units.

What If It’s Not Quiet Enough?

Most window air conditioners are quiet enough to be barely noticeable under normal circumstances.

Top 4 Things to Consider When Shopping for The Quietest Window Air Conditioner

Best Quietest Window Air ConditionersHowever, there are some things you should take into consideration when evaluating an AC’s noise rating

  1. Noise Rating
    The air conditioner’s noise rating is the first thing you should check when you’re shopping for a quiet unit.
  2. Installation
    Window air conditioners are not difficult to install, and most models come with useful installation instructions that can guide you step-by-step through the installation process. However, a faulty installation can make the air conditioner noisy, no matter its noise rating. You should always make sure that you install the air conditioner on a leveled surface. Moreover, you should ensure that the AC’s supports are sturdy and stable enough to support the air conditioner when it’s working without allowing it to move. If you detect any rattling sounds, you should double check the AC’s installation, because the unit shouldn’t produce such a noise.
  3. Insulation
    Sometimes people do not pay enough attention to properly insulating the air conditioner. The insulation will not only increase the AC’s efficiency, but it will also lower the noise it produces. A window AC might have a built-in compressor, but the compressor is facing outwards. It’s true that not even the best insulation will tune out the noise produced by the compressor, but it will surely dampen it so it’s barely noticeable.
  4. Window Sill
    Most window air conditioners can be installed directly on the window sill. You can actually blame the sill for some of the noise the AC produces. If the window sill is not properly anchored, it will shake and rattle as the AC’s motor is working. Not only will this produce a lot of noise, but it can actually affect the unit’s effectiveness as well. One of the most certain ways to make sure your window AC is properly installed is to have it installed by a professional. However, a professional installation can be expensive and it can sometimes be more expensive than the air conditioner. Another way to make sure you installed the
    AC properly is to follow the installation guide. If the unit doesn’t come with a good installation guide, you can check online for solutions or video tutorials, or you can even contact the manufacturer’s customer support service.

Quietest Window AC Buying Guide

There are a lot of things you should take into consideration when you’re looking for the quietest window air conditioner. Here’s what you should look for.

Sizing A Room Air Conditioner

Few things are worse than buying an air conditioner and realizing it’s not powerful enough to cool down the room you install it in. On the other hand, investing in a model that’s too powerful for the room might make it uncomfortable to use. Every time you turn on the unit, it will make the room so cold you would shiver. Moreover, an oversized unit will turn off and on very often which can lead to a higher energy consumption and a lower efficiency.

You can use the following recommendations to make sure the window air conditioner you choose is sized for the room you’re planning to install it in.

  • Measure the room’s surface
    The first step you should take when sizing an air conditioner is to determine the size of the room you plan to install it in. This is an easy process by multiplying the length and the width of the room. You should also take into consideration the room’s height. Air conditioners come with a recommended coverage, but that coverage is estimated using a standard 7’ – 8’ height. If the room is taller than that, you should look for a unit that’s capable of covering a larger surface to compensate. Here’s how many BTUs you need to cover certain surfaces
    150 sq. ft. – 5,000 BTUs
    300 sq. ft. – 7,000 BTUs
    400 sq. ft. – 9,000 BTUs
    550 sq. ft. – 12,000 BTUs
    1,000 sq. ft. – 18,000 BTUs
    1,500 sq. ft. – 24,000 BTUs
    2,000 sq. ft. – 29,000 BTUs
  • Temperature Leaks
    You should also take into consideration the room’s temperature leaks. The sun exposure, the number and dimensions of the windows, and the room’s insulation will influence the temperature leaks. A room with many windows will leak more than one with a single window, and a well-insulated room will lose fewer degrees than one that’s not insulated. Here’s how you compensate for these elements
  • Sunlight
    If the room is sunny during the day, you should increase the BTUs by at least 10%. If the room is shaded during the day, you can decrease the BTUs by up to 10%.
  • Windows
    You should increase the BTUs by 10% for every window that sits in direct sunlight. You can decrease the BTUs by 5% for every window if they’re shaded.
  • Insulation
    The room’s insulation drastically affects how warm it will be during the warm season. If the room is not insulated, you should increase the BTUs by up to 30%, depending on how warm it gets in your area. If the room is somewhat insulated, you should increase the BTUs by 10%. If the room is well-insulated, you should not adjust the BTUs
  • Occupants
    Each BTU rating is estimated for a maximum number of 2 occupants. For every additional person, you should add at least 600 BTUs.
  • Room’s Function
    You should also take into consideration the room’s function. A bedroom has to be cool, but a kitchen has to be cooler. Bedrooms usually have to be cool at night when it’s colder outside, so you can decrease their BTUs by up to 30%. Rooms that house many gadgets and appliances tend to be warmer than those that don’t, so you should increase their BTUs by at least 1,000. If you cook frequently, the kitchen will be the warmest room by far, so you should increase its BTUs by 4,000 units.

Choosing The Right Capacity For A Window Air Conditioner

Quietest Window Air Conditioner ReviewsYou should take into consideration all the factors we exposed above to make sure you choose the right capacity for your window air conditioner. If you’re not sure about the unit’s capacity, even after you’ve taken those factors into account, it would be best to choose an oversized than an undersized unit. Here’s why

  • Undersized Units – If you choose an undersized unit, the air conditioner will run continuously to decrease the room’s temperature. This process can be inefficient, and it can lead to significant operating costs.
    Moreover, since the air conditioner is undersized for the room, it won’t be able to reduce the temperature as quickly as you would wish, or to a comfortable level. In fact, if the AC is undersized you might not even notice it’s on unless you sit right next to it.
  • Oversized Units – If you choose an oversized unit, the AC’s operating costs will surely be higher. However, despite the costs, the air conditioner will lower the room’s temperature quickly.
    In fact, the AC might cool down the room so drastically you might find it uncomfortably cold. If this happens, you can always increase the room’s temperature by selecting the AC’s fan-only operating mode or by turning it off. One of the major downsides of choosing an oversized unit is that it might not be comfortable to use at night. If you leave it on before you go to sleep, you might wake up shivering. If the AC uses a thermostat, it will turn off and on very frequently, further increasing its operating costs.

What Features Should A Window Air Conditioner Have

Window air conditioners can come with many features. Let’s take a look at some of the most helpful

  1. Oscillating Louvers – Air conditioners that use oscillating louvers will spread the cold air faster throughout the room. Instead of blowing the air in a single direction, the models that use this feature spread it from left to right.
  2. 24-hour Timer – Window air conditioners that use 24-hour on/off timers are some of the most efficient models out there. Instead of letting the air conditioner run when you’re not home to make sure it will be cool once you get there, you can simply program it to start before you get home. You can also program the AC to turn off at night without having to wake up
  3. Thermostat – Air conditioners that use a thermostat will turn on and off automatically once they reach your desired temperature to keep it constant.
  4. Power Saving Features – ACs that come with power features will use less electricity to run
  5. Auto Restart – Window air conditioners that use this function will automatically restart using the last known settings in the case of a power outage.

What Are The Advantages Of Window Air Conditioners?

  • Easy Installation – Window air conditioners have an easy installation, so you can install them yourself without paying a professional.
  • Removable – These ACs are removable, so they are good choices for renters.
  • Cheap – Window air conditioners are some of the cheapest models available on the market
  • Good Cooling Capacity – Despite their low prices, these models have good cooling capacities.

How Much Noise Do Window Air Conditioners Make?

Window air conditioners are some of the noisiest AC models available. One of the reasons they produce more noise than other types of units is because they house the motor and the compressor in the same unit. Another reason for their noise is the fact that both the motor and the compressor are inside your house.

Duct air conditioners use a large unit that’s placed outside for the compressor, so even though theoretically they’re louder, you will only hear the noise of the ducts as they blow the cold air in your house. Split ACs use a separate unit as well. These models do not use such a large compressor as the duct models, but even so, the compressor is placed outside your home so you won’t hear it.

However, besides using the same unit to store the motor and the compressor, there are some other factors that make window ACs noisy. One of these factors is their installation. Window ACs have an easy installation, so most people take it upon themselves to install them, without using a professional. And while some people can do a great job, some will botch up the installation.

Not only will a lousy installation make the window AC noisy, but it will also make it less efficient than it should be.

Another problem people often report when installing a window air conditioner is a rattling noise they hear when the AC is working. You might be surprised to find out that the rattling noise is not actually produced by the AC unit, it’s produced by the vibration of the unit’s supports or the window sill. Most often than not, the window sill will vibrate violently when the AC’s motor runs, so it will produce loud noises.

If you make sure the air conditioner is installed properly and that the unit’s support and the window sill are anchored, you will be delighted to discover that the air conditioner doesn’t produce any loud sounds at all.

The Cost of Running a Window Air Conditioner

You might be surprised to find out that determining the running costs of a window air conditioner is not an exact science. Sure, there are certain ways to calculate these costs, but there are also a lot of factors you should take into consideration before starting these calculations.

  • Capacity – The higher the unit’s capacity, the larger the bill. An air conditioner that produces 5,000 BTUs will consume less energy than a unit that produces 25,000 BTUs.
  • Energy Rating – Each air conditioner has an energy rating. As a rule of thumb, most window air conditioners are energy-star rated, so they’re very efficient. However, being efficient is not the same thing as having a low energy consumption. It only means that most of the energy the AC uses is transformed into the cool air.
  • Wattage – Every air conditioner has used a certain amount of energy to run. As you would expect, larger models will consume more than the small ones.
  • Ambient Temperature – Most air conditioners use more than one speed to cool down a room. If the ambient temperature is high, the air conditioner will compensate by using a higher fan speed. This will increase the AC’s consumption.
  • Thermostat – Units that use a thermostat have a lower energy consumption than those that don’t. When they use a thermostat and they reach the specified temperature, the thermostat will stop working and it will only turn on periodically to keep the temperature at a constant level. Units that don’t use a thermostat will run continuously until you turn them off manually.
  • Occupants – The air conditioner will run for longer when there are more occupants in the room. Each occupant will produce heat, so the AC will produce more cold air to compensate.
    Now that you know how to determine the AC’s power consumption, let’s take a look at some concrete examples. On average, running a window air conditioner will cost roughly 60 cents per hour when they’re cooling a room. When they’re using their heat pumps, running the air conditioners will cost roughly 25 cents per hour. Of course, these prices are highly dependent on the electricity cost in your area, the unit’s size, and the ambient temperature.

Keep Your Window AC Quiet For Years!

If you want to keep a window air conditioner efficient and quiet for years you will have to make some periodical maintenance. The first step in doing so is to read the instructions in the user manual. Most manufacturers recommend some maintenance work for their products.

  • Clean The Air Filter – The AC’s air filter should be cleaned at least once a month. You can access the air filter by removing the front panel. Clean it using warm water and a mild detergent or white vinegar. Let it dry completely before reinstalling it. Replace the filter if you notice any tears or holes.
  • Clean The Condenser Coil – You can use warm water and a mild detergent to clean the condenser coil before each warm season to make sure there is no mold or mildew growth on the coil
  • Remove Insect Nests – The air conditioner can provide a good cover for insect nests. If this is the case, you should remove the nests before you start using the unit each year.
  • Change The Remote Control’s Batteries – Make sure you remove the remote control’s batteries before each cold season if you won’t use the AC for heating.

You may also like portable air conditioners or you can choose a tower fan based on its capacity.

Wrap Up

As you could see in our window air conditioner reviews, the best window AC unit is the one that can cover the room you install it in without overdoing it. Even though it can be time-consuming it’s better to measure the room and its temperature leaks twice before deciding on a model.

Besides being silent, the quietest window air conditioners are also efficient. These models can cool down a room in quick succession, without making it so could you’ll shiver. And the best thing is, with some yearly maintenance, these units can last for years if not decades.
