Do air conditioners take in air from outside?
There are a lot of questions and concerns that come with owning a window air conditioner but the most common one is “Do air conditioners take in air from outside?” The answer is No.
Fun fact about window air conditioners is, they actually do not pull outside air into your home. On the contrary, all the air blown through the home is recirculated and filtered by the window air conditioner and the excess heat is what goes outside so with this particular issue, you have nothing to worry about.
The best way to have total control of your devices is to familiarize yourself with each an every one of them. In this article we are solemnly focusing on window air conditioners so here are a few things you need to know.
How does a window air conditioner work
Upon purchase, an instruction manual is given but its very wise to be a little familiar with how it works even before hand. Now you might assume that its a dreadful and complicated machinery but its not.
In order to make your environment more accommodating there are a few things you need to know after installing and turning this unit on.
1. The air cools through the cooling coil inside the unit
When the unit is switched on, the cooling coil drops in temperature because the cooler in the coil is put under pressure by a compressor. The air moving past the coil then cools as well as it is blown back into the room.
2. It allows air to circulate in the room
Dormant, humid and warm air can be extremely unpleasant especially in high temperature areas. If you happen to find yourself in this situation be sure to turn on your window air conditioner.
The blower in the unit will pulls in the hot air and releases cooler and much more pleasant air. This process makes the air in the room circulate hence making it cooler. refirg
3. Temperature can be monitored using the thermostat
The beauty about modern technology is that it can be manipulated to your suitable preference. This particular feature allows you to determine how cool or warm you want your space to be.
Some window air conditioners actually have an “intensity” option allowing you to adjust the blowing intensity of air circulating within the space.
Other window air conditioners have thermostats thus when a desired temperature is met, they automatically switch off while other models operate manually.
4. It moves unwanted heat outside
During the cooling procedure, heat removal from the air is part of the entire process. This is why the exhaust system notably gets warmer and warmer. This particular process is referred to as the hot air cycle.
It occurs when the air conditioners compressor takes heat produced in the process and expels it through the exhaust system.
One thing to keep in mind is that in this unit, outside air does not interact with inside air.
5. It cleans the air inside
It might interest you to know that on top of all the mentioned benefits of installing a window air conditioner,this one is a personal favorite.
Everyone is aware that air is something that easily gets contaminated. Could be with chemicals, dust, smoke and so on. There is a special feature that these units have that take care of that one common concern.
Within the window air conditioner is a filter that aids in purifying and cleansing air that passed though it. This feature allows users it enjoy fresh, cool and clean air for as long as they want.
Now you might not believe me when I say this so just to back up my statement make sure you check your filter to see exactly what I am talking about.
Just make sure to clean the filter regularly and you are good to go.
Now the biggest disadvantage that window air conditioners have is how noisy they can get. If you own one I am well aware of your troubles but don’t worry, I am here to give you a few steps you can use to quiet it down. So without further hesitation;
How To Quiet A Noisy Window Air Conditioner
Installing foam insulation around the unit
In most cases window air conditioner do not exactly fit perfectly into the place they are installed in. There are visible gaps and spaces on the sides where noise easily passes through.
Most air conditioners come with sliders to fill in the gaps but they are usually thin and don’t completely fill out the spaces so the best alternative is to use foam insulation.
This material has proven to be better and more reliable compared to the slides as it completely blocks out the noise and air passing through the gaps resulting in a cooler and quiet room.
The plus side to foam insulation is that it an be cut to the required size and easily installed making it a very reliable tool.
Tightening the unit
Loosened screws create a very irritating noise when the unit is on. This is a very common yet fixable problem.
Once the loose screws are tightened it will reduce the vibration of the window air conditioner resulting in a much quieter unit.
Leveling the air conditioner
Leveling the place in which the window air conditioner is installed is a very essential yet neglected source of noisy units. The smallest gaps in between the air conditioner and the window can leave room for vigorous vibrations.
This can cause very unpleasant noises to emerge. For you to fix this, ensure that the leveling is done correctly before the placement of the window air conditioner.
Using a blanket
Hanging a blanket in front of the air conditioner might seem unusual but this method is said to be effective in most homes when done correctly.
The blanket should be hung five feet away from the air conditioner as the space allows air to properly circulate.
Regularly inspect the fan blades
Window air conditioners primarily have two fans. One that circulates the air back into the space and another that normalizes the temperature of the condenser.
If one or both of these fans are damaged they can result in making an unpleasant noise. Dirt accumulating can also interfere with the functionality of the unit.
Turn off the air conditioner and remove the face plate. Use a brush to lightly clean the blades. If any of the blades are bend, slowly stretch it out to even.
Alter the units motor
If not properly greased, the motor can produce a loud and annoying noise. The solution to this is to add a few drops of oil to lubricate it. If that does not work then the entire motor is defective and should be replaced.
Replacing it with a better unit
If the above solutions do not exactly work out, another alternative is buying or replacing it with a new quiet window air conditioner. With everyday advancing technology, improvements are constantly made such as durability and the entire performance of the unit.
