Types of window air conditioners
Window air conditioners are mainly classified according totheir cooling capacity and hence their appropriateness for differentapplications.
Below you will find these categories and the BTU ratings aswell as their respective cooling capacities.

How quiet is the quietest window air conditioner really?
When it comes to upgrading to a quiet air conditioner,theres one big catch to keep in mind:
Some of the models being marketed as quiet room air conditioners are nowhere near quiet and can be way above the safe noise limits.
So, what levels of noise can you accept when shopping for an ultra-quiet air conditioner?
Well, these days, a super quiet air conditioner may onlyproduce about 25 dBs of noise (just above a whisper!) at the maximum fansetting.
Thats serene enough to nudge you to sleep promptly or reada motivating book in graveyard peace.
Larger units can, however, get louder - they are installedwith bigger fans- and make as much as 55 decibels of noise (just louder than a hummingrefrigerator, which runs at around 40 dBs).
Its thus important that you check the dB ratings (noisemeasurements) on the air cons youre considering to avoid burning cash on adevice that makes zero difference.
Sadly, manufacturers rather conveniently forget to includethis information in the products manual.
Plus, you wont get an opportunity to hear it out beforebuying.
This is why I usually recommend that you run through buyer reviews on websites and other online forums.
First, they help you identify units with deafening noisesfrom independent users.
And secondly (and more crucially), you will get an accurateopinion of a products wholesome quality and value.
Why invest in one
You stand to reap big after switching to the quietest roomac:
Take a look:
- Peaceful coexistence with your neighbors: Your neighbor will be knocking on your door to thank you and not to complain.
- You keep your cool: Air con noise can hit our nerves and make us moody.
- Conducive ambiance: You will do more. For example, you can have a constructive talk with loved ones, watch TV, or get your baby to sleep even when its running. And, you will always get a good nights sleep and concentrate maximally on the tasks at hand.
- No costly legal battles: A ridiculously loud air con could land you in trouble with the authorities.
Often, you have to sift through an avalanche ofmodels to determine the quietest air conditioner thats rightfor your needs.
These tips will make the entire process less painful.
Know your cooling requirements (British thermal units (BTUs) per hour)
The air conditioner size has ramifications on the amount ofnoise with bigger window air conditioners tending to be louder due to the more robustfans.
Let me ask you: why would you pick a product that soundslike a plane where a smaller unit with more amiable noise would do an equallysuperb job?
You dont want to make this mistake and its critical thatyou figure out the unit size thats best for your space.
A BTU calculator like this helps.
And here is a rough guide to show you the way if you findthe calculations tedious.
|Area (square feet)||Capacity Needed (Suggested BTUs per hour)|
|100 - 150||5000|
|150 - 250||6000|
|250 - 300||7000|
|300 - 350||8000|
|350 - 400||9000|
|450 - 550||12000|
|550 - 700||14000|
|1,000 - 1,200||21000|
|1,200 - 1,400||23000|
|1,400 - 1,500||24000|
|2,000 - 2,500||34000|
I cant stress enough how important this is.
Available mounting options
Three window types dominate - standard windows (single/double-hung and sliding up and down), casement windows (that swing out), and slider windows (slides left and right)- and window air conditioners fit differently.
In fact, some of the manufacturers are very clear about thewindow layout to install their models on.
Going through the air con literature will be handy here andwill ensure that you select a product that fits your window quickly and easily(without having to implement clumsy modifications).
The other vital consideration regarding installation is thewindow size- check the actual height, width, and depth of your window andselect one that fits to a tee.
Overlook this and you will have yourself squarely to blamefor the fitting problems.
Pro Tip: Please allow about 3-4 inches (to cater for the accordions) if you will be using a window kit to fix the air conditioner.
Plug cord type for the window air conditioner
Plug types for air cons are availed in multipleconfigurations and you need to have this on your radar when choosing.
Options are 110V/15A plug, 110V/ 20A plug, and 220V/15A,220V/20A, 220V/30A plugs configurations.
The 125V/15A plugs are most common and you might be forced to call an electrician to change the circuitry if you have opted for a model using a plug type with a different voltage and amperage.
Other factors worth considering when searching for a quiet window air conditioner:
- Energyusage- For more power savings, go for a window Ac with inverter technology.
- Heatpump- to follow up on the above point, units with high-efficiency heatpumps are likely to dehumidify better than regular window airconditioners, leading to energy conservation and unmatched cooling comfort.
- Fandesign- Improved sound muffling technology can dramatically reduce noise comingfrom the fan.
- Adds on (convenienceaccessories)- Features such as auto cooling mode, timers, remote control,and such make the product more convenient to use.
