If you are looking to buy an air conditioner for your home or office, then you have come to the right place. Today we are going to give you several tips on how to make the most of the benefits of this device.
First, the most important
- There are two models of room air conditioner. The portable device is for residential use so it is smaller and has wheels. It must be replenished manually with ice water, ice or gel pouch.
- The wall air conditioner is indicated for commercial use, because in addition to requiring a renovation (it must be installed in a fixed location on the wall), the device needs to be connected directly to the water supply system, as the reservoir is automatically refilled.
- You can find air conditioner models with other functions besides cooling the air. Some have a humidifier, heater, ionizer and even a filter. You can also look for extra features like timer function and larger reservoir.

The high temperatures, common in the summer, are great for those who are drinking cold coconut water on a beach or sitting by the pool. But let’s face it, most of us are indoors, whether at home or in the office.
Because of this, there are several devices designed to ventilate, purify and humidify the environment. If you want all these benefits, but don’t know which model to choose, it’s time to get to know the air conditioner, which combines all these functions in one device.
What is an air conditioner?
The air conditioner is a device used to leave your home or office with a pleasant temperature both on hot and cold days. The coolest thing is that the device has several functions and is very simple to use.
To cool the room and bring more humidity into the air, the air conditioner does not use chemicals, but uses ice water, ice cubes or gel bags, which are in a reservoir inside the appliance.
The air that enters the device is directed to this reservoir, it becomes a fresh and humid vapor or mist and returns to the environment. There are two models of room air conditioners:
- Portable air conditioner : this device is smaller and usually has wheels, so it is more suitable for home use.
- Wall air conditioner : the appliance is much larger, of fixed use, more powerful and is connected directly to the water network, to be replenished automatically, this model is indicated for commercial use.
What are the advantages and disadvantages of the air conditioner?
The air conditioner is a model so versatile that it replaces three other appliances: air conditioning, fan and air humidifier, after all it fulfills the main functions of the three.
It refreshes or warms up the environment (we’ll talk about that later), like an air conditioner. It exchanges air just like a fan, pulls dry air and returns humid air, just like the air humidifier.
Another feature of the air conditioner that brings you closer to the fan is the low consumption of electricity. This device has an average expenditure of 14 Kw / month, the same consumption as a fan, which means a minimum amount in the electricity bill.
In addition to being economical, this device is relatively inexpensive. Another advantage in relation to costs, is that you will not need to do any renovation in your home to install a climate control.
In addition to taking up little space, the device has wheels and handles, which allow you to carry it wherever you want: living room, kitchen and even in the bedroom (it emits little noise, so you can use it at night, without impairing sleep ).
Another differential of the air conditioner is that it takes care of your respiratory health, because in addition to making the air very moist, some models have internal and external filters that retain dust, mites, bacteria and viruses.
What is the correct way to use the air conditioner?
To get the most out of the air conditioner, you need to install and use the appliance correctly. Follow the tips below:
- Firstly, it must be positioned at a minimum distance of 15 cm from the wall , as the rear of the device is responsible for the air intake. This distance is essential to optimize air circulation through the device.
- Another recommendation is to place it on a flat surface , to prevent it from tipping over or falling and thereby causing water leakage and possible (perhaps irreparable) damage.
- Avoid placing the device in places where it is usually sunny , as besides being subjecting the electronic parts to overheating, this decreases the efficiency of the device.
- It is also important to keep it away from anything that could block air circulation , either at the air inlet or outlet of the device. This includes furniture and curtains.
- If you are going to use the device in the humidifier function, it is important that the air circulating through the environment is always renewed , so it is essential to keep a window or door open.
- Always place the gel bag (or ice water) before turning on the air conditioner , to prevent the appliance from burning.
- Use industrialized ice instead of homemade ice to fill the cooler reservoir. The reason is simple: industrialized ice takes longer to melt.
- Change the water in the reservoir every time you use the air conditioner. If you use it every day, do this procedure at least three times a week.
How to clean the air conditioner?
The first thing you should do when cleaning the air conditioner is to unplug the appliance to avoid shocks. On the outside, just wipe with a damp cloth and the appliance will be clean.
The reservoir is also simple to clean, just remove the part, wash with running water and a little liquid soap. Then wait for it to dry or speed up the process using a clean, dry, lint-free cloth.
Never use strong chemicals to clean the reservoir like disinfectant and chlorine, as they are bad for your health, especially when used to clean a device that will release the air that you and your family will breathe afterwards.
Other parts that deserve a lot of attention are the external and internal filters, after all, it is essential that they are clean so that the air continues to come out very strong (and clean) from the device.
Use water and mild soap to clean them, then just let them dry in the shade before putting them back in the appliance (first the internal filter and then the external one). If the part is too worn, the tip is to replace it with a new filter. Do this procedure once a week or every 15 days.
See how simple it is to handle an air conditioner:
In what contexts does the air conditioner present itself as the best option?
A relevant factor when choosing an air conditioner instead of other cooling and ventilation options is to consider the contexts in which the appliance will be used and make sure that this is the best option.
The air conditioner is suitable for dry climatic regions, that is, locations where the humidity is less than 75%. In regions with relative air humidity above this percentage (as in the northern, coastal and Santa Catarina regions), the air conditioner ceases to fulfill its function and acts more like an air circulator.
It is also an excellent option in places where there is a large concentration of people, as the device will provide adequate air circulation, reduce the temperature and add more humidity.
Keep in mind that the lower the relative humidity of the air and the higher the ambient temperature, the greater the ability of the air conditioner to reduce the temperature and make the environment pleasant.
Air conditioning or air conditioning?
There is no way to talk about the air conditioner without remembering a device relatively similar in its functions: the air conditioner. But know that both models have features that make them unique.
The air conditioner can be an excellent alternative to the air conditioning unit, as it consumes less electricity and is environmentally friendly.
The operation of an air conditioner is simple: the device absorbs the ambient air, cools it inside the machine and returns it to the temperature selected by the user, which can be hotter or colder than the ambient temperature.
The part responsible for making the air temperature cold or hot is the compressor. This part is only deactivated after the environment has acquired the average temperature selected on the remote control.
Then other parts of the appliance’s cooling system are responsible for maintaining the average temperature and the compressor is only reactivated when it starts to vary.
The air conditioner works like a fan, which forces the air present in the environment to enter the back of the appliance and pass through a reservoir with very cold water or ice cubes, returning to the cooler and humid environment.
Still in doubt about which model is right for you? Check the main differences between the air conditioner and the air conditioner in the table below:
The air conditioners can be found in two versions: the portable model for home use, and the wall (fixed) model, more oriented to commercial environments.
Prices range from R $ 250 to R $ 580 for portable models and R $ 920 to R $ 1,150 for wall models.
Where to buy?
Several stores sell air conditioners, If you prefer, you can buy online, in the virtual stores of the manufacturers themselves, or in larger e-commerces such as Amazon.
At Amazon, for example, you can compare different models and brands, and purchase a product at a very affordable price.
Did you know that the technology used in the air conditioner was inspired by a common practice in Ancient Egypt? The Egyptians placed large jars of water at the entrance to the pyramids, when the air passed through these containers, there was a transfer of heat with the water and it became much cooler.
This is the same principle of operation of the air conditioner: the air at room temperature passes through the cold water tank of the appliance, regulates the humidity, cools and returns to the environment with the lowest temperature.
Purchasing Criteria: Factors to compare air conditioner models
Some features and characteristics of the air conditioners can make your experience with this device even better, as, like any other electronic device, there are models of lower or higher quality air conditioners.
When buying your own, note some important criteria ranging from the most basic functions to the most interesting features. We’ll talk about them in this section:
- Hot and cold air
- Anti-mold and antibacterial filter
- Other resources
Now, check each of these points in detail to make the best choice.
Hot and cold air
In addition to the common air conditioner that makes the air moist and cooler, you will find air conditioner models with the functions of cold and hot air, which allows you to leave the environment cool on hot days and very warm and cozy on cold days.
The best thing is that to switch from one function to the other you just need to press a button, that is, you will not need to take the trouble of taking the water, ice or gel bag from inside the device.
The air conditioner can increase the ambient temperature by up to 12ºC on the coldest days. In function of “cold air”, the device can reduce the temperature of hot days from 5 to 10ºC.
The cool thing is that even in the “hot” function, the air conditioner consumes little energy. The difference in consumption compared to air conditioning is almost 90%. So don’t worry, your electricity bill will keep coming down.
Generally during the hottest seasons of the year, you don’t want to switch off the air conditioner for even a minute, to fully enjoy the benefits of fresh, moist air.
The same goes for the coldest days, when the heater leaves the air warm and the atmosphere much more cozy (no one will want to leave the hot air from the air conditioner).
But to be able to use the device for a long time you will need to invest in a model with a large reservoir. A model with a capacity of 6 or 7 liters lasts 8 to 9 hours.
You also have the option to choose a model that comes with two gel cases. In case you choose this option, leave one freezing while you use the other.
Anti-mold and antibacterial filter
As we mentioned earlier, the air conditioner can be an ally of your respiratory health, as this device makes the air more humid (the relative humidity must be above 60% to be considered good for humans).
What you may not know is that some models come with filters that fight bacteria, mold and dust. The best thing is that these filters are washable, so you won’t need to invest in a new part every time the appliance is dirty.
When washing it, just use water and mild soap and rinse it thoroughly with running water. After drying (let it dry in the shade), put the internal filter first and then fit the external one.
In addition to moist air, free of bacteria, mold and dust, if you purchase a model of air conditioner with ionizer function, you will have an even cleaner air, since this feature eliminates viruses and mites and cleans the air in the environment.
In addition, ions stimulate our body’s blood circulation, minimize respiratory problems and allergies.
In addition to the features we mentioned above, you can find air conditioning units with the following extra features:
- Remote Control
- Base with casters
- Carrying handle
- Digital panel
- Speed control
- Air direction control
- Auto off button (which automatically turns off the appliance when the water runs out)
- Self-heating sensor (deactivates the device when it overheats)
The timer is that type of function that people do not consider important, but that in everyday life makes all the difference, as it brings much more practicality and comfort.
An air conditioner with timer function allows you to program up to 12 hours in advance when you want the appliance to turn on, in which position it should direct the air, the speed at which it should operate and for how long you want it to remain on.
