When the summer heat is beating down on your home, nothing is better than relaxing in an air-conditioned room. If you don’t have central AC, window units are a great way to regulate room temperature beyond a simple ceiling fan.
Window air conditioners are inexpensive but powerful enough to blast some seriously cool air into your home! That said, they do have one major downside. These machines can produce a ton of noise!
With central air, the most you’re going to have to contend with is a slight hum coming from the ducts. The compressor and fan are installed outside where you can’t hear it. With a window unit, all of those mechanics are only a few feet away! While they’re not nearly as loud as portable AC units, they can still produce a considerable amount of noise. If you are trying to control noise inside your home, this can be a problem.
Thankfully quiet window air conditioners do exist. Designed for quiet operation, they’re perfect for keeping cool at night or cutting back on ambient noise throughout the day.

Benefits of a Quiet Window Air Conditioner Unit
Whether you have a quiet unit or not, window AC units offer a slew of advantages. Beyond the obvious cooling benefits, window units give you much greater flexibility.
The devices are built to install onto any standard window sill. There’s no need to worry about making major renovations like installing ductwork. Everything from the refrigerant compressor to the air filter is built into one compact box.
One half of the unit sticks outside the window while the other points inside. Installation is as simple as popping open the window, sliding the unit in place, and securing a few screws! You can place them in your bedroom, a living room, or even an addition without ducting.
While many people think that central systems are best, window units are much more cost-effective. Not only does the unit itself cost significantly less than a whole-home system, but it’s much more affordable to run.
Think about how much energy is wasted cooling down a 2,000 square foot house. Chances are, most of that space isn’t being occupied. So, why spend money cooling it down? With a window unit, you’re cooling down the specific room you’re in and nothing more.
Quiet systems take things a step further by addressing the biggest complaints homeowners have about these machines: the noise levels. With standard window AC systems, you have to deal with continual noise as it runs. Throw in the occasional boom of the compressor kicking in and it’s nearly impossible to use these machines at night.
Investing in a quiet model lets you get the peace and quiet you deserve. Perfect for hot sleepers, quiet window units minimize noise by using more efficient components. Advanced compressors, streamlined fans, and some careful engineering can cut back on noise significantly.
Some brands also modify the design to insulate your window a bit better. This helps to block out some of the commotion coming from the components outside.
Things to Consider When Choosing a Quiet Window AC
So, how exactly do you find the quietest window air conditioner? There’s not exactly a standard when it comes to noise levels. Thus, you’re going to have to dig a bit deeper and consider everything the unit has to offer.
Use the information in this buying guide to zero in on the best unit for your needs.
The most important thing you’ll want to look into is the amount of noise the unit produces. Not all manufacturers will provide this data outright. But those that designed the system with quietness in mind will often use it in their marketing materials.
To get some reference, standard window units can produce anywhere between 40 and 60 decibels of noise depending on the operating mode. A standard conversation with someone standing next to you is roughly 60 dBA.
A 20-decibel jump might not seem like a lot. A jump of only 10 decibels is actually a big jump in perceived loudness. The difference between 40 to 50 decibels is almost double!
Of course, several factors will contribute to perceived loudness. Where you are in the room and how intense the cooling settings are will change how loud the system is to you.
To keep things simple, go with the lowest possible decibel rating you can find. Lower ratings are always better when you’re looking for a quiet machine.
What good is an air conditioner if it doesn’t effectively cool your room? A machine’s cooling capacity is represented as BTU unit. BTU, or British Thermal Unit, is used to measure heat transfer. A higher BTU rating means that the machine can move heat out of the room faster. It directly correlates with your room size.
If you have a small room, you can get away with getting a unit with only 5000 BTU. That’s usually enough to cool down a room with only 150 square feet.
But you have a larger room that you’re looking to cool down, you might need to jump up to 10,000 BTUs or more. With 10,000 BTUs you can cool a 350 square foot room.
Window units are available in a range of ratings. There are even heavy-duty models with 36,000 BTUs! Choose a BTU rating that’s appropriate for your room. Other than cooling the room down faster, there are no major benefits to getting a system with more cooling power than you need. So, choose a rating that’s as close to the size of the room as possible.
Window air conditioners can be as simple or as advanced as you want! More affordable systems utilize simple knob controls. They work just fine, but they can be a pain when you want to make changes from across the room.
To do that, you’ll need a unit with remote control. More advanced systems can connect to Wi-Fi. With a complementary app, you can adjust settings, create schedules, or even turn the system on before you get home.
Energy costs are an important consideration. Running powerful AC units doesn’t come cheap. Generally, systems with higher BTU ratings will cost you much more to run than those with lower ratings.
Several factors will affect your running costs. These include your current cost per kWh, how often you run the AC, and how much energy the system uses.
Use any available energy guidelines to get a better idea of what the unit will do for your electric bill. Pay close attention to the EER rating. EER, or Energy Efficiency Ratio, provides some insight into a system’s power consumption. A higher EER rating is preferred, as this means that the appliance uses less electricity. To keep costs low, invest in efficient Energy Star products.
More performance options are always preferred. Cooling features vary wildly across the board.
On simpler machines, you’ll get limited cooling options. You might have only a few preset temperatures or cooling speeds to choose from. Those systems are still worth considering, but you won’t have fine-tuned control.
More advanced air conditioner units have more flexibility. You can set the thermostat to an exact setting and let the machine do the work to keep things stable. You may also have access to adjustable louvers, multiple fan speeds, and dehumidifier controls.
Tips for Keeping Your Window AC Quiet
Buying the quietest air conditioner on the market can make all the difference when it comes to noise levels. But, that quietness is fleeting. Window units are notorious for getting louder as they start to experience some wear and tear.
To maintain the low noise levels, you must maintain your air conditioner. Check on the compressor, fan, and other moving parts regularly. Clean the exterior of the unit, remove fallen leaves, and apply some lubrication to the fan to keep it running smoothly.
Also, pay attention to the power cord. If the power cord becomes damaged, you run the risk of experiencing a short. It could also start having issues maintaining constant power. This results in intermittent stops and a regular vibrating noise.
Finally, keep the air filter clean. Most units nowadays have a washable filter that you can clean in minutes. Removing accumulated dust and grime will improve the system’s efficiency and keep noise to a minimum.
