Buyer’s Guide: What to Consider when Buying a Quiet Window Air Conditioner?

The market has so much more to offer when it comes to window air conditioners. However, they are not created equal, so you need to find out which unit best suits your needs. Here are the main factors that you should consider when shopping for a quiet window AC:

Noise Rating

The noise rating of an air conditioner is one of the most important factors to check out. A quality quiet window AC shows this rating as among its main features. Check your preferred unit for this one. 


A window air conditioner is hard to install. Typically, most models have installation instruction manuals with easy and simple directions that you can follow even on your own. Extensive knowledge about installing an electronic appliance is no longer necessary when installing a quiet window AC in your room.

Moreover, be sure that the supports of your AC are stable and sturdy enough to support an air conditioner. If you hear rattling sounds, check the installation of your device and reinstall it if necessary. 


Failing to consider the air conditioner’s proper insulation is one of the common mistakes people do when buying and installing a quiet window AC. Insulation is very important because it boosts the efficiency of the air conditioner and lowers the noise produced during operation. 

Stop relying on the built-in compressor alone as it might be facing outwards. While the best insulation does not eliminate the noise coming from the compressor, the insulator will dampen it to make the noise less noticeable. 

Window Sill

Window air conditioners allow direct installation on the window sills. And, the window sills are sometimes the culprit of the noise coming from the ACs. 

This will likely happen if the window sills aren’t properly anchored. If that is the case, they will shake and jangle while the motor of your air conditioner is working. It leads to more noise and reduced efficiency of your device. 

One of the best ways to ensure that your window air conditioner has been properly installed is to entrust the job to a professional. The problem here is that hiring a professional to install the window AC for you is somewhat expensive. The service cost can even be twice the price of the air conditioner. 

If you still prefer to install the air conditioner yourself, then be sure to follow the instructions given in the manual. If the package doesn’t include a manual, then you may check for video tutorials on the web. You can also seek help from the manufacturing company’s customer support department. 

How to Choose the Ideal Capacity for a Window AC?

When you buy a window AC, you have to be sure its power is enough for the room you’re looking to cool. If you are not sure regarding the capacity of the air conditioner, then keep in mind these things:

  • Undersized Units – if your unit is undersized, then it will run consistently to reduce the room temperature. The process is inefficient and more expensive. Since the air conditioner’s power and size are not enough for the size of your room, it cannot lower the temperature as fast as you want it to. 
  • Oversized Units – if the air conditioner is oversized, then the operational costs are sure to escalate. However, the unit will be so efficient in reducing the room temperature. It can cool the entire room sooner than you think. The room will be cold, and the temperature can go down further, making you feel uncomfortable. Leaving it on before you sleep is not a good thing. If you do, you may end waking up in the middle of the night while shivering. If your air conditioner is using a thermostat, it will continuously turn off/on while you sleep, which will increase the operating costs.

Features to Look for in a Window Air Conditioner

Window air conditioner does offer multiple features. The following are the most useful ones that should be available in any window air conditioner you planned to buy:

  • Oscillating Louvers – window ACs that are using oscillating louvers tend to spread the cool air quicker across the room. They do not blow the cool air in just one direction. Instead, these units having this feature spreads the air from left to right. 
  • 24-Hour Timer – the window air conditioners using 24-hour auto on or off timers are a few of the most effective models available. Instead of allowing the ACs to run when you are away to keep the space cool until you go home, just let the unit run before you arrive. You can also use this feature to turn the unit off on its own at night. You don’t need to wake up. 
  • Power Saving Features – air conditioners also have power features that consume less energy. These features are so helpful in terms of reducing the operating costs of your unit. Hence, you get your room cool day and night without paying more for electricity every month. 
  • Thermostat – window air conditioners need a thermostat to allow automatic turning off and on to help reach the desired temperature while keeping it consistent throughout the night. 
  • Auto Restart – window ACs use this feature for automatic restart using the previously known settings during a power outage. 


Which AC cooling is the best window or split?

When it comes to cooling power, the split air conditioner is typically best for bigger rooms because it can cool the room faster. A window AC looks compact and is best to use for a small room like your bedroom. 

Can Window AC cool the entire house?

A smaller central AC unit draws a minimum of 15 amps of power, cooling a bigger portion of the house or even the whole space depending on its dimensions. A window air condition draws less electricity but can cool the space, provided that its cooling capacity matches the size of the room. To cool an entire house, you may need to get a window air conditioner for each section.

Are quiet window air conditioners real? 

Yes, they are. There has been a wide array of quiet window ACs in the market that guarantees noiseless but efficient and affordable operations.


Which is the best of all these 10 quiet window air conditioners? 

Well, if you’re looking to cool a medium-sized room, then go for Koldfront WAC12001W. With 12,000 BTU, you will enjoy a relaxing and comfortable cooling and heating power. Yes, you can use it as a heater. 

If it’s a smaller room, then consider that one from hOmeLabs. It goes with those features that enable it to cool the entire space. 

Or, if you want a window AC that is easy to install and use and equipped with more features, then it could be Frigidaire FGRC1044T1.
