 Buying Guide – best air conditioners 2021 on the market

 The need to be well informed about the qualities that a product can offer you, as well as the particular demands that you want to cover in your tastes or environment are fundamental to obtain the optimal benefit in terms of quality-price. Therefore, we have devised this guide to buy the best air conditioner on the market and help you make the smartest decision.

Best Air Conditioners 2021

Energy efficiency and space of use

When you go to buy an air conditioner, you should not only worry about its power to cool a room, but also the efficiency with which it uses that power to fulfill its function, while maintaining energy consumption that does not embezzle your pockets.

This performance is known as the Energy Efficiency Index or EER (for its acronym in English), information that comes in the manuals and on a sticker on the back of all air conditioners 2021 on the market. A +++ is the best rating for savings and F is the worst. The closer to A +++, the less energy expenditure the product has.

Another element to consider, very important along with energy efficiency, is the relationship between the space you want to air condition and the power of the device. First and foremost, measure the square area of ​​the place where you will place the air; Once this is done, the minimum reference data is 5,000BTU for an area between 30 and 45 m 2 . Do not expect immediate cooling, but rather efficient, because by cooling just the right amount, the appliance will lower the temperature and gradually eliminate the humidity to offer you a pleasant environment, so it is important that you let the appliance work.

Thanks to this information, you may be able to buy a cheap air conditioner that can meet your needs without spending extra money.


Another of the main elements to consider when buying an air conditioner are the functions and technology it incorporates to fulfill its function, in addition to facilitating its handling and performance.

The controls offered by air conditioners 2021 are important when it comes to manipulating them and regulating their operation: the traditional ones are those with a knob that have established positions, so you can adjust the speed or temperature only to the pre-programmed by the manufacturer. However, some companies have incorporated digital keypads for greater comfort and control by the user. Remote controls are also provided so you can regulate the temperature from wherever you are in the room.

Another important feature, which goes hand in hand with the controls, is that the appliance has a thermostat, preferably adjustable (although almost all models have it today), as well as a fan function with various speeds to reduce energy consumption and provide better distribution of the air that is injected into the room.

All air conditioning brings with it a kind of grid that serves as an air filter, which is responsible for retaining dust particles, pollen or any type of residue that can affect the health of those who enjoy the fresh wind provided by the device. But you must be careful to clean it regularly (1 time every two weeks, at least), to ensure that the air continues to run as clean as possible.

Best Air Conditioners 2021


This is quite an important point to address, because air conditioners 2021 require a generally professional installation to ensure maximum performance and, more importantly, that it does not fall off the window or wall opening in the one to be installed.

Usually when you buy one of these, you bring a simple installation kit for “simple surfaces” like a window or space designed specifically for it. However, it is your duty as a buyer to evaluate the measurements of the device to compare them with those of the space in which you will install it and thus avoid an error in the purchase or an error opening the space in your home. You should have a section for installation in your budget, because if you are not fond of repairs and modifications at home, you will have to pay the store or a friend to install it for you.

If you don’t want to have a problem with mounting, you can always opt for portable models, which limit the installation to placing a simple tube in the nearest window. In addition, these models have the advantage of being able to place them in the room you need at any time without complications.

 Frequently asked questions

 Q1: Where to put the air conditioner at home?

One of the biggest doubts that arise when installing air conditioning in our home is where to place both the outdoor and indoor units. The outdoor units are not very problematic as it is enough to find a balcony or terrace not too far away to place them properly. However, regarding the indoor units that release the cold air that cools the environment, it is necessary to choose wisely which rooms we want or should cool.

The good news is that we have more and more products that can work with two or even three indoor units with a single compressor, which allows adequate air conditioning of several rooms. As a general rule, it is recommended to air-condition one of the main rooms, such as the dining room or the living room, where we spend most of our day during the day.

And it is also advisable to air-condition the master bedroom to prevent the heat during the night from causing us sleep problems. In any case, if your home requires comprehensive air conditioning, it is also possible to find models with a tube system that allows this to be achieved. However, these solutions have a considerable cost both for the installation part and for the electricity consumption.

 Q2: Where to put the air conditioner in the bedroom?

One of the issues in which air conditioning helps us the most in summer is to sleep well. However, an improper installation of this air can lead to problems such as colds and colds, which are very annoying during this time of year.

To avoid this type of problem, it is recommended to install the air conditioning in a position that indirectly cools the area where we are going to sleep. For this reason, installations in which the air flow is directed directly over the bed should be avoided, it being recommended that this air runs parallel to it and without actually touching it, which avoids these cooling problems. With this we manage to refresh the environment but without a continuous feeling of cold.

 Q3: Why does the air conditioner get cold?

Just as a knife does not cause cuts if we do not use it improperly, the air conditioner does not catch a cold, unless we use it incorrectly. The two incorrect uses that we usually get colds and that we usually give to the air conditioning have to do both with its installation and with the temperature that we have established.

Starting with the installation, it is common for the air conditioning to be installed with the air jet pointing to the area where we are going to sit, if it is installed in a dining room, or towards the area where the bed is, if it is done in a bedroom. This continuous jet of air ends up causing health problems such as the aforementioned colds, as well as other problems such as arthritis and joint or muscle problems. Something easy to solve if we install the equipment to carry out indirect cooling over the room, cooling the environment and lowering the temperature.

The other part of the problem is found when the temperature setting is much lower than it should be. In general, for comfort, it is recommended not to lower the air conditioning temperature below about 24 degrees during the summer. This temperature is adequate to properly cool the room without generating a considerable temperature jump, which is what ultimately causes colds. Because imagine what it can mean to leave a room at a temperature of 19 or 20 degrees to another room or to the street where the temperature can be around 40 degrees. In the end, it is the drastic change in temperature that ends up giving us a cold.

 Q4: How to charge the air conditioner?

The air conditioning charging process is carried out with very specific machinery designed for this purpose and that is connected directly to the charging sockets that practically any air conditioning incorporates today. However, it is essential to know that if it is necessary to charge an air conditioner it is because there has been a loss of gas that is probably due to a leak in the system. Therefore, before proceeding to carry out this load, it is necessary to locate and properly seal this leak to prevent the problem from reproducing itself and the equipment from continuing to not function properly.

 Q5: Who installs the air conditioner?

When installing the air conditioning we can use the services of a professional or we can take care of ourselves. If we opt for external help, surely the store where we buy this air has a mounting system to make everything easier. If you prefer to install it yourself, today most air conditioners 2021 use a universal kit, which we can buy directly in any establishment, with the necessary parts to carry out the corresponding assembly. High technical knowledge and very specialized tools are not usually necessary, as long as your drill is capable of drilling the walls to the necessary level.

 Q6: Who fixes the air conditioner?

When it comes to fixing the air conditioning in our home, the professional we should turn to is any air conditioning company. A professional that we must select properly although we will not always have to resort to the official service if we do not need it. In any case, whenever we have a problem with the air conditioning, it is advisable to refer to the manual to verify if we can solve this problem ourselves and save ourselves the odd annoyance.

Air conditioners 2021  are widely used around the world, especially in hot seasons, but deciding which one to buy is not an easy matter. First, we must carefully review the size of the area we want to cool, to know how much power we will need. And something very important that many miss is the energy class of the appliance, which is very important because air conditioners 2021 are among the appliances that consume the most electrical energy. We have done an analysis of the characteristics of some of the most important models and we have also reviewed the comments of many users on the Internet, finding that one of the best air conditioners  2021 is the Fujitsu 3NGF8700, which can cool and heat the environment, is quite silent and has energy class A.
