Understanding Portable Air Conditioners
Portable air conditioner units (also known as portable ACs) are compact, mobile cooling systems designed to provide cooling and air conditioning to individual rooms or limited spaces without the need for a permanent installation.
These portable units typically consist of a main cooling component, an exhaust hose, and, in some cases, a window venting kit.
In situations where you don’t have access to a window, venting can be a challenge but it’s still achievable.
The purpose of a portable AC unit is to cool down a room by removing heat from the air inside. To do this effectively, the warm air must be expelled out of the room using an exhaust hose.
Without proper venting, the hot air will stay trapped inside the space, leading to higher temperatures and reduced cooling efficiency.
Tips On How To Vent A Portable Air Conditioner Without A Window
The first question I get asked a lot is, “can I use a portable air conditioner without a window”? The answer is yes, you can. Sometimes, we may discover the need to split a bigger room into different compartments to provide more accommodation and privacy in the home.
It’s a normal thing, and the use of a portable AC will be an ideal option in keeping the room cool and comfortable for whoever will be occupying it.
So if you have a room in your home without a window that you wish to acquire an AC for, then you can follow these tips to vent your AC without inconveniencing anyone or making your AC to underperform.
1. Vent the AC through a nearby wall
Many individuals prefer this process. But you have to get creative a bit and pick the right spot to point the hose of the AC. You should also remember that the reason you are venting your portable AC is to get hot air hot.
Now when you mount the AC in the corner of your room, you can bore a hole in the wall where you can channel the hose conveniently. You can direct the hot air outside the house or into another room such as the laundry room, garage, or laundry room.
You should also ensure the hole bored is big enough for the hose to pass through. If it’s not, don’t be afraid to increase the circumference of the hole to accommodate the tube.
Next is to seal the openings around the hose from the AC. You can use Silone caulk for this one. The idea is to ensure that hot air doesn’t re-enter your room from where you channel the hose to.
It’s also to ensure that hose does not fall off the hole when the AC starts working.
Warning: Do not channel the hot air into a room that is frequently being used. Also, if you are going to direct the hose into your laundry room, ensure the room has windows or openings so that the hot air can escape outside and not renter your home.
Another thing you need to be careful about is to point the hose of your AC away from your window. In other words, it should not be close to the window of your sitting room or another room.
2. Vent the air conditioner through a dryer vent
Well, I have to be honest with you; many producers do not recommend this method of venting a portable air conditioner.
But if it’s the only option you’ve got, why not? You can give it a shot. Many individuals have been able to vent their ACs this way successfully.
Now, why do many producers kick against venting a portable air conditioner through a dryer vent?
The reason is simple. Many of the dryer vents you will find have smaller-sized holes. And as a consequence, it is difficult for the hose of an AC to pass through them.
But if you can connect the hose of your AC into it, then you are good to go. You have to make sure the hot air is not entering your room. That’s it.
So, keep testing and see how you can creatively connect your hose through your vent dryer and send the hot air away from your room.
3. Vent your portable AC through a drop-ceiling
This technique is quite effective for venting a portable air conditioner. But then, you have to put your creativity at work to get the result you seek.
You have to reconfigure your panel or drop ceiling, to transform it into a ventilating area. You will find such reconfigurations in computer server rooms. That’s what they use. The reason is that such places don’t have windows.
Now how do you vent a portable air conditioner via a drop-ceiling?
First, locate a ceiling panel you think is ideal for you to pass the AC hose through.
Make a hole in the ceiling, and ensure the hole is neat. Next, move the tube through the hole created in the ceiling panel and add a sealant to keep the hose firmly in place.
4. Venting Through Chimney
Lastly, you can vent your portable air conditioner through a chimney if your home has one. Simply connect the exhaust hose to a vent inside the chimney, ensuring it fits securely.
This method allows warm air to escape through the chimney, making it an efficient venting option.
Keep in mind that you should not use your fireplace while venting the air conditioner through the chimney, to avoid any safety hazards.
Why Is Learning How To Vent A Portable Air Conditioner Without A Window Important?
If you are reading this and you already have eyes on a portable air conditioner, then you are not alone. People have started realizing how important having a portable air conditioner is in the home.
But some of them are cautious because their proposed room where they intend to mount the air conditioner might not have a window.
But then, is not having a window in your room a yardstick for not mounting an air conditioner that can keep you and your family comfortable? The answer is, NO!
Now, here is another question I get asked a lot;
Will a portable air condition function to capacity without a window? The answer is no. We have already answered this question at the beginning of the article. But there is nothing wrong in answering it again.
Now back to the importance of venting a portable AC. Why is it necessary? Why should you even care?
Why don’t I keep my AC in a room, sitting down and turned on, instead of venting it? But here is the thing; all portable air conditioners whether movable or settled will eventually deliver a hot stream of fumes. That’s one of the things taking place in the engine that you can never see. It’s the side effects that AC’s have.
Anyway, that’s how AC’s work. You have to understand this before buying one. If you are not comfortable with it, then don’t buy it! But AC’s are too relevant to ignore.
Another thing you need to know is that room temperature air finds its way into the unit where it passes through the inside registration process, which compares to a local ice chest.
Now the point is the warm room temperature air gets constrained through the cooling radiator. But when it comes out, it comes out chilled and dried.
What happens is that the chilled, dry air is pulled from the AC unit into the room where the portable air conditioner is placed, through a fan stationed in the device. But the opposite of this is the hot air forged by the blower. Now allowing this warm air to flow back into the room will make it impossible for the AC to keep the room chilled.
So your aim for buying an AC will not be achieved. You don’t want that, do you? So you see why it’s essential to have suitable aeration and cooling system. The hot air has to go somewhere but certainly not in the room.
Now you know what can happen when you don’t vent your portable AC, right? The hot air will remain trapped in the room, and no matter how long you keep your AC working, it will never cool down the room. Instead, it will only become hotter and more uncomfortable for you or whoever is staying there.
Venting, as you can see, also helps to get rid of moisture from the air. And as you know, the lesser the humidity in your room, the colder the room will become. But once you are unable to vent your portable air conditioner, then you can expect moisture buildup in the room. And as this continues, the cooling effect of your air conditioner will become neutralized entirely.
6 Things To Know When Using a Portable Air Conditioner
Now using portable air condition is cool. However, there’re things you need to consider before using one in your room. These factors are quite remarkable. You need to take a quick look at how you can live with a portable AC mounted in your room.
So besides knowing how to vent a portable air conditioner without a window, let’s look at other factors you need to consider before mounting a portable air conditioner in your room.
1.The noise the unit produces
If you are someone who cannot sleep in a room with an appliance that’s a bit noisy, you need to think correctly before splashing the cash on an AC. Noise is something you need to pay the utmost consideration to when shopping for an AC.
And like reading the ultimate buying guide on the best refrigerator cord, you will find tips on noise levels produced by different AC units. Still, you are going to have to deal with noise from AC. In other words, whether you buy a central or portable AC, all ACs are noisy.
Here’s one advice on noise levels of AC’s
Yes, all ACs produce noise. So you will have to deal with that. But the noise levels vary from one brand to another. That said when before you buy a portable AC, check the unit carefully to ascertain the noise level it produces. Looking up the noise suggestions for each AC will give you a clue on which to choose.
Again, you can request the AC you wish to buy to be put on and observe the noise level while working. If you think the noise is something you can handle in your room, then you can go ahead and purchase the said portable AC.
2. Energy efficiency of the AC unit
Paying more because you have a portable AC mounted in your home is not a wise thing to do. If that’s the case, then it’s not worth it. However, all single portable air conditioner available comes designed with an energy efficiency rating (EER).
So look carefully, you will find this rating. Also, the higher the EER rating, the more efficient the portable AC in question is.
But here is something you need to know;
Portable units are more energy-efficient than the bigger and permanent ones. Have that in mind before you splash the cash on an AC.
Again, amongst the various portable ACs, some consume less energy. In other words, the EER rating differs amongst portable air conditioners. So before making your final decision on which to choose, compare the various air conditioners to know the one that meets your requirement.
3. Not all rooms and spaces are convenient for portable ACs
There are specific ways AC functions that make it unfit for certain places. You can have a portable AC in your room but not in places like your garage. Another place not ideal to use a portable AC is an unfinished basement.
Why can’t you place an AC in your garage or unfinished basement?
The answer is simple, and before our eyes. Now here is the thing; the structure of the garage or unfinished basement will make it more difficult for the AC to keep the environment cool. So, avoid these places.
Now back to the room. You need to have at the back of your mind that ACs need some breathing space. So, it’s improper to place yours in a closet or cabinet. Even if you tuck it in a corner in your room, it should have enough breathing space.
4. Using an extra exhaust in your AC
AC comes designed to function in a specific manner. You can also deploy some form of creativity with regards to how you make use of the exhaust hoses that come with your AC.
The question I get asked a lot is; can I attach a hose to the one on my AC?
Unfortunately, it’s not possible. You cannot add or remove hoses from your unit. And please, don’t try this. If you do, you can cause a severe problem to its function.
The kind of problem I am talking about is the one that can affect the unit’s compressor. When the pressure is too much, the compressor will likely shut down entirely or develop a fault.
And as you know, your warranty might not cover damages done to the compressor. The only possible way you can solve this problem will be to get a brand new AC or get a technician to help you repair the damaged units.
Evaluating Efficiency
When it comes to venting a portable air conditioner without a window, it’s essential to consider the efficiency of the process.
Efficiency can be evaluated based on factors such as temperature, humidity, energy-efficient features, and the energy efficiency ratio (EER) rating.
- Temperature: Venting a portable air conditioner effectively helps maintain optimal indoor temperature. If the temperature inside the room is consistently comfortable, that’s an indication that your venting solution is working well.
- Humidity: Portable air conditioners typically include a dehumidifying feature that helps reduce excess humidity in the room. An efficient venting solution will help you control indoor humidity levels, ensuring that the environment is neither too damp nor too dry.
- Energy-efficient features: Modern portable air conditioners offer various energy-efficient features, such as programmable timers, sleep mode, and adjustable fan speeds, which contribute to reducing energy consumption. Choose a unit with these options to maximize efficiency when venting it without a window.
- Energy Efficiency Ratio (EER) rating: The EER rating measures the energy efficiency of an air conditioner. A higher EER rating means the unit cools the room effectively using less energy. Look for a portable air conditioner with a high EER rating to ensure optimal efficiency when venting it without a window.
While venting a portable air conditioner without a window presents challenges, it is still possible to achieve a desirable level of efficiency by considering the factors mentioned above.
By evaluating the temperature, humidity, energy-efficient features, and the EER rating, you can ensure that your portable air conditioner functions optimally and provides a comfortable living environment in any room without a window.
