Summertime is the perfect time to test out your home air conditioning unit. If it’s been a while since you’ve used it or if you’re considering purchasing an air conditioner for the first time, it’s important to understand how they work and whether they need to be vented.
In this blog post, we’ll discuss “do all air conditioners need to be vented” and answer some common questions about venting. Stay cool!
do all air conditioners need to be vented?
Most of the air conditioners are required to be vented. We generally use Air conditioners to maintain the temperature of our house. An AC can adjust the temperature according to your need. However, it has other functionalities too.
Air conditioners can also reduce humidity by getting rid of the warm and moist water vapors from the environment. That’s how it achieves this reduction in moisture.
When an air conditioner starts its cooling procedure, it creates a massive quantity of warm air as a by-product. You must vent this air outside. Otherwise, it will negate its own freezing, and the primary purpose of having an AC will be lost.
The necessity to Vent An Air Conditioner?
The question regarding venting arises mainly about portable air conditioners. The other alternatives for air conditioning you’ll get are mostly either wall split or Ceiling Cassette air conditioners.
These split AC’s are generally mounted on your wall or fitted on your ceiling. It contains an outdoor unit it which discharges the heat absorbed from your room outside. The manufacturers make these units built in on these types of air conditioners. So, You don’t have to bother about additional venting anymore.
On the contrary, there is no outdoor unit on portable air conditioners for this removal purpose. Thus, all of them need venting.
So, you must’ve learned already that venting is a necessary process for almost all the portable Air Conditioners we use. How important is it? Does it have any workaround? Let’s find out.
The Working Method Of An Air Conditioner
To know the necessity of vending, you must learn the process used in an AC to maintain temperature. Is it similar to a refrigerator? Or is it just a higher functioning fan? Well, let’s see.
Air conditioners are different from air coolers because the conditioning here means more than cooling your room. It not only drops the high temperature but also maintains a balance between other factors of your surroundings.
An air conditioner lowers the temperature while maintaining humidity, moisture, ventilation, and the number of vapours. So it has to take in clear air from outside and surrounding while draining some from your room.
Therefore, it is essential to have a discharge unit on an air conditioner to remove the hot air. While the split air conditioners, be it wall mounted or ceiling, have an outdoor portion, portable AC’s does not. So, they need different venting options.
What Will Happen To Not Vent Your Air Conditioner?
First of all, a split air conditioner doesn’t need venting anymore. They have their way of removing heat. However, if your air conditioner is portable, read the following part carefully.
The temperature will not fluctuate noticeably if your air conditioner does not have a discharge pipe or any other way to remove the heat. So, the area will not be cooled. The portable air conditioner absorbs heat from the surroundings. So there should be a way to discharge it. That is why it requires venting.
Without the venting process, the AC will absorb the heat. But instead of removing, it will return the heat right back inside again. This process might reduce the humidity of the environment this way but will not reduce temperature.
Moreover, it will start running a cool and hot cycle in your room. It consumes a lot of electricity which also generates heat. So, as a result, it might end up increasing the temperature of the room way further than it would cool off.
Ultimately, it’s not much dangerous to not vent your air conditioner. But, it’s neither efficient at all to have or run a portable air conditioner with no venting.
Ways To Use An Air Conditioner Without A Vent
You can definitely have and use an air conditioner without a vent. But if it’s portable, it’s almost like not having it at all. It is inconceivable to use a portable air conditioner without adding a vent. You might turn it on, but it will not do the job it’s supposed to.
It will not operate properly without venting. So running it like this will not be different from not running it at all.
If you do not have any other way, suppose your room is windowless; what is the remedy then? If you live anywhere like that or want to use an air conditioner in a room with no windows, then there are several ways we discussed to operate it efficiently. You can check on them if necessary.
Venting Techniques of An Air Conditioner In A Room With No Windows
Nowadays, window vent air conditioners are very popular all over the world. Around 75-85% of people would like to buy an AC with a window exhaust vent.
Because of the popularity of window vents, many manufacturer companies provide a window seal kit to their customers without any additional cost. So, if there is a window, it won’t be a hassle to set up a vent.
However, Though it is difficult to use an air conditioner with no window venting option, it’s also impossible to do. We’ve discussed the techniques to operate a portable AC with no window vent and without venting at all.
1. Installing Through the door
It is possible to not have any window or exhaust way in your room. But not having a door in the room? Well, that’s impossible. You can utilize the door of a room to easily vent your AC. This is the most familiar and easiest way of venting for those who have no window in their room.
However, try to use a door to the balcony or a small room door. Because, If the door is a hall room or any other bigger room, you might not get a satisfactory temperature from the AC.
And If you have a sliding door for venting, we have good news, venting with a sliding door is as efficient as the window venting process. You can try this without any hesitation.
2. Installing Vent Through The Wall
The wall in a room is also another way to use for venting. But for venting this way, you must create a hole in the wall. Be careful to maintain the diameter of both the hole and pipe the same when piercing the wall.
Also, it would help if you choose the correct wall for making a hole. Do not choose a thicker wall or steel wall. It might not be helpful for your air conditioner.
3. Using The Dryer Vent
The venting process of the dryer vent is not much different from an air conditioner. In fact, Many AC manufacturers advise using a dryer vent in order to vent a portable Ac.
First, drill in the dryer vent. Then you can simply install your air conditioner vent in that hole.
But this method has some limitations. You will not be able to vent an air conditioner properly with a 6 feet exhaust pipe. It is safer to buy a hose with a length of 20 feet or more and install it. Then you would be able to set the air conditioner in any bigger rooms also.
4. Venting through the ceiling
Generally, offices, malls, and prominent windowless buildings use this method. For this venting method, you need a dropless ceiling where you would like to set up the AC.
As offices have drop ceilings in most cases, it is easier for them to use ceiling venting. This ceiling is not much used for any office work. So you can make it useful by using them as a venting process.
You have to use special drop ceiling kits to install the AC vent on a ceiling like this. These kits can extend the length of the hose according to your need. Try to set it up beautifully.
5. Using the chimney
This venting process is not quite familiar to us, and to be honest, this method is also not easy. There are many requirements to make use of this process.
First, you need a chimney in the room which is not used for any other work. Then use the chimney to fit a venting pipe through it. Installing the hose through the chimney is very tough. It is hard to do it on your own without an expert. There are safety factors to consider.
The chimney procedures are frequently used in tiny cottage-type houses.
What To Use For Complete Ventless Use Of An Air Conditioner?
If there is no way you can vent your air conditioner, don’t be sad. There are still methods you can apply to cool your room without going through the hassle of venting.
We discussed split air conditioners before. They are used for fitting in the wall or ceiling. You can choose any of them to buy. However, you have to take expert help to install them in the house or office.
Moreover, there is an option to use ductless air conditioners. It can be used instead of portable AC’s. They do not require venting as no hot air or fume, or gas is produced by them in the process. It just repeatedly circulates the air that is already in the room.
You can also try a swamp cooler which uses humidity to cool the air. It evaporates water and absorbs your room temperature. Then cold water vapor is released to cool your room. However, it’s not recommended to use in humid places like any tropical area.
As you can see, almost all air conditioners need to be vented. While portable air conditioners use a typical hose system for venting, split air conditioners use separate heat units. So, if you’re using a portable air conditioner, use venting to get the most of it.
