    Size Of The Room

    On the market, there are a lot of air conditionals, and they tend to come in different sizes. That is why we need to think about the size of your room in the first place. So, for the first thing, we would like you to ask yourself a question if you are going to use it in an office, in a living room, or in a bedroom. If you are going to use it in an office, we recommend going for the one that quite a big one that can blow up the strong wind at a good temperature. For example, 1,5000 to 20,000 BTU per unit.

    For the use in the living room, the one with the medium size is enough because the living room is not that big. However, the one that you need to think of carefully is the one that you are going to use in your bedroom. For your bedroom, the small or medium one is good for you because you might not use it all the time.

    Energy Consumption

    The next thing we would really like to talk about is the amount of energy that the wall air conditioner will consume. This is a very important thing because if the air conditioner consumes much energy, your electricity fee will be more expensive as well. For example, most air condition consumes up to 0.8 kilowatts in an hour which is not much. That kind of air conditioner is the one that you probably need to own one because you would not spend a lot of money on electricity fees.

    Moreover, people averagely use air conditioners for 2 or 3 hours a day which is not that much money, and it only uses up 2.4 kilowatt-hours per day. If you choose the wrong one, you would need to spend a lot of money every month.

    Special Features

    To keep your family members and yourself up-to-date, you might need to own an air conditioner with loads of special features. Those features can be very useful for you because sometimes it takes care of your health and the environment. For instance, there is a quite popular feature from Samsung which allows the wind to come out of 23000 small holes without pleasant direct wind. That can keep you moisturized all night, and it will not make you uncomfortable.

    There are some more features that we need to have in an air conditioner, such as the timer, the echo mode which can save energy, and reduce the sound of the AC. You need to remember, the more the features, the better it is.

    Ease Of Setup

    When you buy a new wall air conditioner, you would need to sacrifice your time to set it up because it is not as easy as a walk in a park. We know that you do not want to spend more time to just have all the things done. That is why our next point is going to be about the ease of setup. So, what is the most important we are seeking? Of course, that is an instruction book.

    The reason is that you need to have it to guide you when setting the air conditioner up. That can help you with the main points, and you can do it easily in less time which is really nice. Furthermore, if there is an instruction book included, you will not need an electrician or professional to set all the things up for you.

    Ease Of Cleaning

    Last but definitely not least, it is about the ease of cleaning of an AC. That is a simple thing to clean the air conditioner after using it for quite a while. If you do not clean it, you can breathe the dust sometimes as well. Therefore, knowing how easy to clean an air conditioner is a very good thing. Before buying one, it requires you to do some research about the air conditioner you are about to buy to know if it is easy or not. Then, you can go and buy the one that you can clean without any obstacles.
