What types of air conditioners are there?

The two experts agree to distinguish two types of air conditioners: fixed and mobile.

The first ones count : the wall-mounted air conditionerit is a sort of box, which, as its name indicates, is fixed on the wall. The console air conditioner, similar in appearance to a radiator. The Cassette air conditioner which is in the form of a rectangular grid and is installed in false ceiling and the ducted, which is placed in the same way. These products benefit from a simple diffusion system (mono-split): with a unit outside and a unit inside but in a single room; or multi-split: with an outdoor unit and units in several rooms (up to five) in the house / apartment. The authorization of the town hall for the installation of a fixed air conditioner is not required, unless you live in a protected area. On the other hand, you will have to obtain the approval of the majority of the co-owners, if you live in apartment.

How does an air conditioner work?

The air conditioner says "split", also called air / air heat pump, is able to get hot with cold and vice versa. This air conditioner recovers the calories outside, thanks to a unit fixed on the facade, it transforms them into hot or cold air which it diffuses inside via a second unit, fixed it on the wall. "You can get hot and cold temperatures down to minus 20 ° C and up to 50 ° C," says the Airwell product manager. "The mobile air conditioner, on the other hand, draws air from the room on one side, which it refreshes or warms (depending on the function) to diffuse it on the other," adds Boulanger's Seasonal Cold Product Manager.

What power is required?

"The power of an air conditioner is calculated Like an electric heater, "begins Maximilien Fontaine," 1 kW = 1,000 watts, choose it according to the room where it will be installed. "Take into account the exposure of the latter: when the room is exposed full South with bay windows, better a more powerful device, "advises Lucie Ciarletta." Before clarifying: "The power of mobile air conditioners varies from 2000 to 3500 watts. They are used, according to the models, in all rooms from 12 to 40 m2; manufacturers indicate for which volume the device is designed. "The two pro agree to recommend an average power of 100 to 130 watts per m2 for a ceiling height of about 2m 50." Attention to the number of decibels that diffuse the material, especially in the rooms. The sound level of our machines is 21 decibelsThis is what is most silent. Avoid in this room exceed 22/23 decibels", warns Maximilien Fontaine, on this point, the seasonal cold product expert insists:" Mobile air conditioners emit a sound volume between 45 and 60 decibels. If the device is to be used in a room, prefer a model with "night" function, the sound emitted is then hardly noticeable ".

What does an air conditioner consume?

The consumption of an air conditioner is of course standardized and we find products of energy class A +++. The better the device is classified, the less it is energy-consuming. An electric heater type toaster consumes, for the same comfort and the same power 4 times more than a fixed air conditioner, according to the expert Airwell. These devices are developed and thought to favor theenergy saving. "A house in France of 100 m2 consumes, on average, in electric heating 13750 kWh, which represents nearly 1914 euros.At the same period and the same surface, a pump with heat air / air consumes 4500 kWh, or 630 euros", details Maximilian Fontaine.

And Lucie Ciarletta rebound: "The higher the power, the more the mobile device consumes electricity, hence the importance of adapting its power to the size of the room, soavoid over-revving. If a device has a power of 1 kiloWatt (kW), it consumes 1 kWh in 1 hour. 1 kWh costs almost 15 euro cents, excluding subscription. "Also, be sure to run the unit continuously, with average power, and finally, make sure the room is properly insulated to avoid temperature differences: always for consumption, but also for health reasons. temperature difference between the outside and the inside should not exceed 8 degrees, "she continues. As a reminder, these devices tend to meet certain health expectations and to clean up indoor air. Mobile air conditioners are equipped with either an active carbon filter, effective against odors, or an electrostatic filter against dust and bacteria, with this type of filter, most pollutants are eliminated, says the specialist Seasonal cold product from Boulanger. "Some filters retain up to 99% of bacteria, it is up to the customer to know his requirements at this level," says Maximilien Fontaine.

Where to place his air conditioner?

A Fixed air conditioner requires the intervention of a specialist able to manipulate the refrigerant charge, but also to identify the ideal location of the device. Depending on the type of indoor unit and the configuration of the space to be developed you have to imagine the best positioning possible: do not think of placing your air conditioner above the sofa, near a door. "On the other hand it is quite possible to put an air conditioner under a window, like a radiator," continues the Airwell product manager.

"We have developed a 3D configurator that helps the customer visualize the possible results, at home, according to the various proposed solutions," he develops. Lucie Ciarletta, meanwhile, indicates again that the mobile model is always placed near a window.

An air conditioner, how much does it cost?

For a single-split fixed air conditioner (reversible), count 1200 to 2900 euros, for an air conditioning with console between 2000 and 2500 euros. Remove about 500 euros for an air conditioner of this kind but not reversible. Air conditioning systems (multi-split) with cladding or in the floor are installed during the construction of the building or during major renovations. Their price, established according to the configuration of the space and the number of pieces to reach, can easily exceed 4000 euros. The range remains wide enough for a mobile air conditioner: from about 160 to 1000 euros.

Is the installation of an air conditioner subject to tax reduction?

"Having an air conditioner does not bring you any tax benefits, but a certificate of energy saving," says Airwell Product Manager. Since it is desirable to draw the expenses that the heating generates downward, in the new housing the heat pump air / air is more and more present. "And, the RBR (Reflection Responsible Building, ed) advocates a replacement of electric radiators by this type of installation in older buildings.In addition, we take the fold of the connected home.The air conditioner communicating with air is now easily Programmable from our application Airwell Sensibo, a control system that remotely controls the operation of its air conditioner, regardless of the refrigerant used, brand and technology Airwell Sensibo can connect to all types of air conditioners that work with An infrared remote control The WiFi function is used to manage the air conditioner on and off, the temperature, the fan speed or the timer.The wireless installation is equipped with a "Plug & Play" system consisting of a hub (router) that can control alone up to 10 indoor units in the same house, "he continues.

How to maintain it?

The maintenance of an air conditioner remains the key to its proper functioning. Once a year, have your fixed air conditioner checked, its filter changed, like the refrigerant charge. Invoice estimated at 100 euros.

Do you have a mobile air conditioner? If equipped with an electrostatic filter, wash it every month with soapy water. If it is an activated carbon filter, change it every year. And above all, do not forget regularly dust off your device.
