How Do Window ACs Work?
Window air conditioners work by drawing in hot air from a room and cooling it down using a refrigeration cycle.
The hot air is pulled into the unit through a vent and passed over a set of cold evaporator coils filled with refrigerant gas, typically freon.
Refrigerant takes heat from the air, turning it into a cold liquid.
The air conditioner makes the air cold and sends it back out into the room using the fan. The hot air is sent outside where it goes over the hot coils.
The hot air from the refrigerant goes outside, and the refrigerant turns back into a gas.
This cycle repeats itself continuously until the desired temperature in the room is reached.
Window air conditioners have a special button that allows you to make the room cooler or warmer and to change how fast the air comes out.
This makes it easy to make the air cooler or warmer, depending on your preference.

A window air conditioner has four main components:
- Compressor: This is the heart of the air conditioner. It compresses the refrigerant gas, which then moves through the other components.
- Condenser: This component cools the refrigerant gas and turns it back into a liquid. It’s located outside of the unit and expels heat to the outside air.
- Evaporator: This component absorbs heat from the inside air and turns the liquid refrigerant back into a gas. It’s located inside the unit and is responsible for cooling the air that is blown back into the room.
- Fan: The fan blows air over the evaporator and pushes the cool air back into the room. It also helps to expel hot air from the condenser to the outside.
Criteria used to choose eco-friendly quiet window AC
Energy efficiency rating
We looked for AC units with a high SEER rating (Seasonal Energy Efficiency Ratio). If the SEER rating is high, then the AC unit is more energy-efficient. This helps save energy and money on electricity bills.
Noise level
We selected units with a low decibel rating, so you won’t be disturbed by a loud buzzing noise when the AC is on.
Eco-friendly features
We looked for units with eco-friendly features like using a refrigerant that does not harm the ozone layer and ones with recyclable components.
How many decibels is a quiet air conditioner?
A quiet window air conditioner should make a noise below 52 dB. Normal levels for a window AC are between 50dB and 56dB, which is still quiet.
If the noise level is below 46dB, it is a very quiet unit. Our list’s quietest window air conditioner is 40dB, but some expensive models can be as low as 30 dB.
40dB is as quiet as a library, so it’s probably quiet enough for most people.

Should I Consider a Portable AC Over a Window AC?

On a hot day, you may consider purchasing an air conditioner to help you stay cool.
There are two types of air conditioners: window ACs and portable ACs.
Window ACs are big boxes that you put in a window.
They can cool a whole room well, but they can be hard to install and they can’t be moved easily.
Portable ACs are smaller and can be moved from room to room.
They work by blowing cool air into the room and sucking warm air out through a tube that goes out a window.
Although they can make a bit more noise than window ACs, portable ACs are simpler to set up and can be used in multiple rooms.
So, if you want to cool just one room well and don’t need to move the AC around, a window AC might be better for you.
how to soundproof window AC
If your window AC is too noisy and you can’t buy a new, quieter one, there are some things you can do to make it less loud.
Location
First, check the location of the AC unit.
If it’s close to a wall or other hard surface, it may be bouncing sound waves back into the room.
Try moving the unit away from any walls or hard surfaces to see if this makes a difference in the noise level.
Regular maintenance
It’s important to regularly clean and maintain your AC unit to keep it working properly.
Dirt and debris can build up on the fan blades and cause excess noise.
Clean the filter regularly and schedule professional maintenance as needed.
Insulation
Use foam weatherstripping tape to seal any gaps between the AC and the window frame.
This can help reduce noise from outside.
Soundproof curtains
Install soundproof curtains or blinds over the window to help absorb sound waves and reduce noise from outside.
Soundproofing box
Make a DIY soundproof box by building a wooden frame around the AC and lining it with soundproof insulation.
This can help reduce the noise the AC makes.
Floor mat
Place a sound-absorbing mat or rug on the floor near the AC to help absorb any sound waves that bounce off hard surfaces.
Upgrade
If the noise level of your AC persists even after trying the above steps, you might want to think about getting a new AC unit that is designed to operate quietly.
