1. INTRODUCTION
Whether it's a new home or an office, choosing the air conditioner that best suits your needs is a rather important moment that necessarily requires precise assessments and great attention. In addition to economic reasons, in order to understand which air conditioner is best suited to our specific air conditioning needs, it is first necessary to clarify some fundamental points for the purpose of an optimal choice: currently, in fact, there are various types of air conditioning, each with its own characteristics and advantages.
First of all, it is good to keep in mind that today, on the market, there are air conditioners capable of cooling in the summer and heating in the winter. The main benefits deriving from an air conditioning system are comfort and reduced running costs. Substantially, air conditioners differ for residential applications (specially designed for purely domestic use) and for commercial applications (designed to best adapt to the particular needs typical of offices, shops or other work environments): the most evident difference is that linked to the powers of the individual outdoor units and the maximum number of indoor units that can be associated with them and their type. New technologies allow current air conditioners to purify and/or dehumidify the air (using special filters), to air-condition environments only in the presence of people or to be controlled by smartphone even when you are not at home.

2. WHAT IS THE FUNCTION OF AN AIR CONDITIONER?
An air conditioner is an electronic device that essentially has 3 functions: cooling, heating and dehumidifying.
Generally, in its operation, an air conditioner uses a completely inert fluorinated gas (R410A or R32), but it is important to know that if you have an old model, you can continue to use it until an irreparable failure occurs or the battery runs out. gas (only if the refrigerant is excluded from the market). As far as the heating function is concerned, it is advisable to use the heat pump, instead of a heating system powered by other heat sources, as energy consumption is reduced. As far as the dehumidification function is concerned, it must be considered that the sensation of heat is often dictated in part by the presence of humidity in the surrounding environment. In these cases, activating the "dehumidifier" function of your air conditioner is the best choice as it allows you to reduce the stuffiness without sudden changes in temperature (notoriously harmful for the elderly and small children), while ensuring reduced energy consumption.

3. HOW TO CHOOSE THE RIGHT AIR CONDITIONER
There are many criteria for opting for one model over another. In order to make an informed and informed choice, it is first of all necessary to clarify things: the most important thing, if you are completely undecided about what is best to buy, is to contact our staff for precise and professional advice. In this guide you can find some indications and basic elements, useful to be able to guide you in your evaluations.

4. CLASSIFICATION OF AIR CONDITIONERS
Current air conditioners are all equipped with Inverter technology and are able to guarantee a good yield in continuous use: this technology, in fact, involves the use of a thermostat capable of regulating the temperature by setting it to the desired levels according to one's needs and to keep it stable by adjusting to the minimum. In this way, and also thanks to automatic delivery variation systems based on the actual request for cold, an Inverter system represents the ideal solution for those who need constant operation over time, silent and with high energy savings.

5. ARE THERE AIR CONDITIONING SYSTEMS WITHOUT EXCHANGE OF OUTDOOR AIR?
There are air conditioners on the market that do not require an exchange of air with the outside: they are water-cooled air conditioners that use this fluid to cool the battery. All other types of air conditioners (even monobloc and portable ones), in fact, need to expel hot air outside the cooled environment.

6. TYPES OF AIR CONDITIONING SYSTEMS
There are essentially 2 types of systems: fixed air conditioning systems and portable air conditioners.

The fixed ones, in turn, are divided into systems with external and internal units, systems with water-cooled motors and packaged air conditioners. In the first case it is necessary to install an external motor and a certain number of evaporating units inside, in the second case the water-cooled motor is installed inside the house as well as the evaporating units, monobloc air conditioners require a installation on the perimeter walls of the house.

As far as indoor units are concerned, however, there are the following types: wall mounted units, floor consoles, ceiling suspended units, recessed ductable units, cassette units (1-way or 4-way) for modular ceilings and column units.

7. ARE THERE DIFFERENCES BETWEEN AIR CONDITIONERS AND AIR CONDITIONERS?
In reality, there is no difference between an air conditioner and an air conditioner: an air conditioner, in fact, is nothing more than an air conditioner equipped with a thermostat that allows you to adjust the desired temperature and keep it unchanged on the set level.

8. CHARACTERISTICS OF THE FIXED AIR CONDITIONER
The fixed air conditioner is characterized by two distinct components: the external unit, which includes the compressor, and the internal unit which includes the condenser and the evaporator. With this type of air conditioner it is possible to air-condition several rooms even with a single outdoor unit: in this case we are dealing with a multi-split motor which supplies all the power necessary to several indoor units for air-conditioning the different rooms. This solution allows for considerable savings in terms of space and costs.

9. PORTABLE AIR CONDITIONER CHARACTERISTICS
The portable air conditioner simply consists of a single element, resting on wheels, on which the compressor, condenser and evaporator have been directly mounted. A portable air conditioner can be the perfect solution for lowering the temperature in small rooms without necessarily requiring the intervention of installers. This type of air conditioner is not very noisy, but it is certainly louder than the fixed ones (considering that the compressor is inside the room to be air-conditioned); moreover, for its correct functioning, it is necessary to keep the window open to allow the hot air to be expelled from the pipe. The greatest advantage is certainly that of being able to be moved easily and without difficulty where the need is felt.

10. HOW IS THE POWER OF A SYSTEM MEASURED?
The power of an air conditioner (fixed or portable), is measured in refrigeration (Frig/h), BTU (British Thermal Unit) or kW (kilowatt).
To know the requirement necessary to refresh a given environment, it is sufficient to perform a precise calculation by multiplying the cubic meters of the environment to be air-conditioned by a variable thermal coefficient according to the geographical position and the type of room. Other factors that affect the calculation of the requirement are the characteristics of the windows and doors (for example, the presence or absence of double glazing), exposure to the sun, shaded outdoor areas and the number of people and electrical equipment present on average within the environment. Before proceeding with the purchase of an air conditioner, in any case, it is advisable to rely on professionals in the sector in order to request an inspection by an installer who will carry out the precise calculation of the necessary needs.

11. HOW THE THERMAL NEED OF A SPACE IS CALCULATED
The most common approach for quickly calculating the heating (or cooling) requirement of a room, with the aim of selecting the most suitable air conditioner, is to obtain its volume and multiply it by a value ranging from 20 to 30 W/m3 . Unfortunately this empirical method, which does not take into account other determining factors, could reserve unpleasant surprises such as poor cooling, poor dehumidification or even excessive cooling. Precisely for these reasons, we suggest that you contact professionals in the sector in order to request an inspection by an installer who will carry out the precise calculation of the need for "fresh" water.

12. THE ENERGY CLASS OF AN AIR CONDITIONER
Every air conditioner on the market must now compulsorily show its energy class in a clear indication. On a classification scale, the energy consumption of an air conditioner, which goes from the letter A to the letter G (with increasing consumption values), is reported on the ErP energy label; moreover, for each class there are three sub-values which provide further information on the energy efficiency of the machine, in order to guide the purchase in an even more informed way.

13. THE NOISE OF AN AIR CONDITIONER
An important feature of any air conditioner is its noise level. Today there are various models on the market which guarantee low noise levels during operation which, in some cases, can be further reduced by a special "silent" mode which allows almost total silence to be achieved (something to be taken into consideration above all for installations for domestic use, an environment in which excessive or annoying noise could disturb you and your neighbours).

14. MISTAKES TO AVOID WHEN BUYING AN AIR CONDITIONER
In this paragraph we will bring to your attention some observations that should not be underestimated and some situations on which it is good to clarify.

A portable air conditioner is not really effective, I prefer to buy a stationary one.
It is not always true that a fixed air conditioner is the ideal solution: it could even be an unnecessary expense and to understand this, it is good to first carefully evaluate the choice. A portable air conditioner is light and can be easily moved from one room to another according to the needs of the moment, it costs less than a fixed one and is most often the best solution in cases where you want to air-condition small rooms subject to only a few hours of heat and sultriness per day.

The portable air conditioner I have doesn't cool my house well, so I change it.
The purpose of a portable air conditioner is not to cool an entire house, but simply the environment in which you choose to place it. If the need is to air-condition all environments (domestic or work), then the solution is well represented by a fixed air-conditioning system, with mono-split or multi-split external motors, depending on the size and needs.

Not paying adequate attention to the data relating to the cooling power, defined in BTU, necessary for effective air conditioning of the rooms.
This is a very important aspect as it is an indication of the machine's cooling capacity in a given period of time. Carefully evaluate the products you are examining before proceeding with the purchase and always seek the advice of an expert installer, especially if you intend to install in large rooms.

Do not consider the noise level of an air conditioner declared by the manufacturer.
Another rather delicate point, as the silence of an air conditioner is important, especially if you live or work in a condominium context. The ideal would be to have an air conditioning system that overall does not exceed 40 dB; above 65 dB the system begins to produce an annoying noise (especially if you consider that you have to live with it during operation). Pay particular attention to the sound level of the outdoor unit.

Surely my 3 Kw of domestic users are enough for the system I intend to buy.
It is not at all obvious that this is the case: depending on what you choose as a solution for your cooling needs, the system could require more power in kW. So it is better to check this point first and, if necessary, request the upgrade to 6 kW.

I want the air conditioner installed in my bedroom, perhaps right above or in front of the bed.
Absolutely not recommended, since placing the indoor unit so close could cause health problems and annoying pains (such as back pain or stiff neck); furthermore it is certainly not the most effective way to air-condition the environment during the night. The solution could instead be to install the internal units in "strategic" points of your home, where the air can radiate more easily where it is desired. We recommend that you always refer to a qualified installer who can best advise you on this too often underestimated aspect.

My air conditioning filters are now worn out, but I can't find the right replacements.
Our advice is to always ask, at the time of purchase, what type of filters can be mounted on the appliance and the recommended replacement frequency (generally, this type of information can also be found in the booklets or manuals of the appliance). 'use). In this way you will immediately have the possibility to check the costs and availability of the filters that interest you, especially if they are "special" filters such as photocatalytic, activated carbon or titanium and catechin filters.

Of course the cost of the installation is included in the price I paid!
Are you quite sure that's the case? Be careful and always remember to ask for detailed information about it, as most of the time the installation costs are not included and can often represent a considerable expense. Better think about it first.

Forget to ask about warranty extensions and maintenance contracts.
Sometimes, when you buy an air conditioner, an extension of the warranty or a maintenance period may be included in the price: always ask the person who sells you the air conditioner if they provide services of this type or not.

15. HOW TO INSTALL AN AIR CONDITIONER
Installing an air conditioning system is not a simple operation, on the contrary, especially if done for the first time and with few knowledge available. For this reason it is always advisable to request an intervention directly from specialized technical personnel, who are also able to advise on the most suitable arrangement of the outdoor unit based on various factors, including exposure to atmospheric agents and the power of the motor which could represent an unwanted source of heat on a balcony.

16. WHO SHOULD I CONTACT FOR AN INSPECTION AND FOR INSTALLATION?
