How to choose your 9000 BTU mobile air conditioner

Your home is less than 30 m² and you are looking for a good mobile air conditioner to cool the air in your home? Take these parameters into account before making a final purchase.
choisir climatiseur mobile 9000 BTU

#1 - Location

The best location for such an air conditioner would be next to a window or, better yet, near a door that is ajar so that the exhaust hose can be run through it. Most of the current models come with caulking kits that will prevent you from having a heat exchange. If you have chosen a 9000 BTU packaged air conditioner, you don't need the help of a qualified professional. Split models require more attention. Containing refrigerant, be sure to handle the unit carefully.

#2 - Model type

In the 9000 BTU mobile air conditioner sector, we mainly discover 2 types of models: monobloc and split.

  • The mobile air conditioner 9000 BTU monobloc : it can be with single or double pipe. This is the most common model. All air conditioning options are included. The unit evacuates hot air through a flexible duct of 10 to 15 cm in diameter. It takes up very little space, is less expensive and is very easy to use despite its high noise level.
  • The mobile air conditioner 9000 BTU split : like the classic split models, this one is essentially composed of 2 units that you must connect via flexible ducts. The outdoor unit includes a compressor and a condenser while the indoor unit includes an evaporator and a control panel. As a rule, the unit is much quieter, more compact and lighter than the packaged air conditioner. However, it is difficult to move.

#3 - Energy efficiency or EER

Pay attention to the energy efficiency ratio of the 9000 BTU mobile air conditioner or its EER (Energy Efficiency Ratio). This is actually a measurement standard that can be calculated as follows: divide the cooling power of the unit by its electrical energy consumption. The higher the number, the less energy the 9000 BTU mobile air conditioner will be considered to consume. Note that all models are classified by category (from A to G). It's best to choose a mobile air conditioner that offers an energy efficiency rating of A.

#4 - Noise level

This is a factor not to be overlooked if you plan to place the 9000 BTU mobile air conditioner in your bedroom. Of course, there is no such thing as a perfectly quiet model since it has a compressor and a fan. However, you can focus your choice on a unit that emits as little noise as possible. In the best of cases, some models offer a silent function in energy saving mode or in night mode. The sound volume of such equipment usually hovers around 48 dB to 70 dB.

#5 - Additional features

Additional features or comfort options give you the assurance of optimal convenience of use. These include:

  • The remote control : you will have better management and full control of your 9000 BTU mobile air conditioner without having to get up.
  • The connected application
  • The programmable timer : ultra convenient if you want to cool your home before your arrival, stop the device automatically, save money ...
  • The activated carbon filter : it eliminates and prevents bad smells, dust and bacteria. It is an essential element for people suffering from asthma or any other respiratory disease.
  • The reversible character : some devices have the capacity to heat a room in winter or to ventilate it in summer.

How to install and maintain a 9000 BTU mobile air conditioner?

The 9000 BTU mobile air conditioner does not require any particular installation and especially it does not require any hole in the wall, unlike a fixed air conditioner or a heat pump. All you have to do is unpack it, read the user's manual carefully and connect it to an electrical supply. However, to get the most out of your model, learn more about its operation, installation and maintenance in the rest of this article.

How a 9000 BTU mobile air conditioner works

Basically, a 9000 BTU mobile air conditioner is used to lower the heat level in a room. It performs much the same function as a refrigerator, using a refrigerant to recover heat from the air. It then condenses the heat and vents it to the outside of the house through the exhaust duct. The 9000 BTU mobile air conditioner is equipped with transport wheels that make it easy to move. The reversible model, in particular, can be used as a heating solution in winter.

The installation of the mobile air conditioner 9000 BTU

There are some slight differences in the installation of the 2 categories of 9000 BTU mobile air conditioners. Nevertheless, the installation is quite easy.

  • The mobile air conditioner 9000 BTU monobloc: you are required to put it in place in the room to be air conditioned as is the case with a mobile radiator. It is imperative to install it as close as possible to a window or the exhaust vents.
  • The mobile split air conditioner 9000 BTU: it is better to install it near the openings, the indoor and outdoor units can not be too far from each other since the extraction duct is maximum 3 m.

The performance of the 9000 BTU mobile air conditioner depends on the length of the exhaust duct. The longer it is, the more condensation or even mold will form within the 150 cm long pipe. Preferably, choose to install it near a sliding or tilting window and at a distance of 30 to 40 cm from the wall.

9000 BTU mobile air conditioner maintenance

Regular maintenance of your 9000 BTU mobile air conditioner will ensure its proper operation and performance. There are several steps to follow, including turning it off before cleaning. Start with the external surface and clean it with a damp cloth or sponge. Then, take a vacuum cleaner and get rid of the dust that has accumulated in the filters. If necessary, don't hesitate to dust them with a soft brush and soap, or even run them under running water for a better cleanliness. As for descaling, a specific product will be necessary. Be sure to use only descaling solutions recommended by the brand.

Mobile air conditioner 9000 BTU with or without exhaust ?

9000 BTU mobile air conditioner with exhaust

By definition, a 9000 BTU mobile air conditioner is a kind of heat pump using almost the same operating principles as a refrigerator. Therefore, it will suck the hot air contained in the room where it is installed to then cool it with its integrated compressor before redistributing it. The operation will be repeated several times until the desired degree of heat that you have set is reached. The level of precision depends primarily on the model. The speed at which the temperature is reduced is based on the power of the mobile air conditioner 9000 BTU, the volume of the room to be cooled, but also the current ambient temperature. The device collects the heat and then expels it outside the home via a duct.

Mobile air conditioner 9000 BTU without exhaust

As the name implies, this type of 9000 BTU mobile air conditioner is ductless. It is actually an air cooler (a perfect combination of air conditioner and fan) because it works in the same way as condensing or evaporative units, without using refrigerant. The water contained in it is transformed into fine droplets and is projected into the air via a fan. The hot air then starts to lose its heat energy. It is distinguished by its very affordable cost, its small size and its lightness. On the other hand, it is noisier and less efficient if the room is larger than 15 m². These models require frequent water refills, which is not very practical.

Verdict

In case you plan to cool a room of 25-30 sqm, the 9000 BTU mobile air conditioner with exhaust is highly recommended. It is quite easy to move it thanks to its multidirectional wheels. It can be controlled remotely with a remote control or a built-in Wi-Fi connection. You must put it near a window or a door that is ajar for the installation of the flexible duct. Although the two devices act in the same way, the mobile air conditioner without exhaust is quite different. Using the evaporation phenomenon, it has no pipes and contains no refrigerant. It is however an excellent solution for punctual needs, because its radius of action cannot go beyond 15 m².

Why buy a 9000 BTU mobile air conditioner?

pourquoi acheter climatiseur mobile 9000 BTU

Reasonable price

The cost of acquiring a 9000 BTU mobile air conditioner remains low. Such a device can be bought from 250 €. If you want a higher-end model with a multitude of features, expect a minimum of €400. From there, prices vary depending on the model and power selected. Just keep in mind that you need 10 W of power per square meter of surface.

Great simplicity of installation

One of the main advantages of the 9000 BTU mobile air conditioner is its ease of use. Moreover, you are able to move it at your convenience. All you have to do is install the exhaust hose to direct it outside and you're done. Because it's so easy to install, you don't need an expert to do it.

More practical than a fan

Unlike a fan, the 9000 BTU mobile air conditioner is relatively convenient. While a fan blows the air to keep you cool, an air conditioner lowers the temperature. That's why the cool air stays cooler longer even after the system is turned off.

Easy to move from room to room

The 9000 BTU mobile air conditioner requires no installation work. It is equipped with multi-directional wheels that will make it easy to move from point A to point B. You can use it in your bedroom as well as in the living room. In addition, it can be stored in your basement or garage without any problem.

An excellent backup solution

There are a number of things to keep in mind when using a 9000 BTU mobile air conditioner. It's a backup solution, which means you shouldn't place it too close to your bed or sofa. The exhaust system must be completely free. Note that it does not support long use and too intensive use otherwise it will quickly get damaged.

Tips

Prevent temperature differences

In general, the outside (warmer) and inside (cooler) temperatures are not the same. We strongly recommend that you do not exceed a difference of 8°C between the two to avoid thermal shock. In addition, since the unit will consume more energy at start-up, you can reduce the risk of power outages by installing an air conditioner inverter.

Use a caulking kit

The 9000 BTU mobile air conditioners come with an exhaust hose giving it the opportunity to expel air outside the home. For optimal cooling, make use of a caulking kit. Together with the flexible duct, this accessory will ensure a cool atmosphere inside. They will limit the possible temperature losses.

Cool the room preventively

The 9000 BTU mobile air conditioner needs a lot of energy to regulate the temperature of a room. So if you want to save money, use it preventively. In this sense, turn on the air conditioning system first thing in the morning, when the air is still cool. It will then only maintain this good temperature without consuming too much energy and without emitting more noise.

Consider the recommendations for maximum surface coverage

In principle, the 9000 BTU mobile air conditioner is recommended for a maximum area of 30 m². The thermal loads vary according to the configurations of your home. Indeed, they will be higher in the case of a room very exposed to the sun and whose insulation is less. If the room exceeds 30 m², the room will not cool properly, the desired temperature will not be reached and the equipment will make a lot of noise.

Reduce the number of electrical appliances according to

The performance of your 9000 BTU mobile air conditioner will be strongly affected in case you connect many other electrical appliances in the same room. To improve and optimize the cooling capacity of the mobile air conditioner, remember to unplug all your electronic devices (desktop computer, vacuum cleaner, oven...), which can produce heat, before turning it on.

FAQ

How to remove heat from a 9000 BTU mobile air conditioner?

The 9000 BTU mobile air conditioner can discharge the hot air inside the room through a flexible duct called exhaust hose. This will pass through a window/door. It sounds contradictory, but even though the gap may leave more hot air, which can jeopardize the efficiency of the device, it will quickly reduce the room temperature.

How to operate a 9000 BTU mobile air conditioner?

Like other air conditioning systems, the 9000 BTU mobile air conditioner requires a power supply to operate. Once the power cord is connected to a power outlet, the motor begins to run. The unit draws in and collects the air in the room. The heat from the air is transferred to the refrigerant before being discharged through the hose at the back. In turn, the air projected inside your home is cooler.

How to remove hot air from a 9000 BTU mobile air conditioner without a window?

Ideally, the installation of a 9000 BTU mobile air conditioner should be done as close as possible to an opening to the outside, a window more precisely. If this is not possible, you can always install it near a door. Place the air conditioner so that the exhaust path is as short as possible, even though it comes with a stretch duct. Drilling a hole in the wall will be an option, but the air conditioner will become fixed. On the other hand, if you opt for a model without exhaust, the efficiency and performance will not be the same.

How to caulk a window for 9000 BTU mobile air conditioner?

First clean and dust the supports (frames and sashes) for a better adhesion. Place the grip strip on the inside face. Then proceed to attach the caulking sheet. Make sure that the narrow side is on the moving part of the window. Finally, open the zipper, insert the drainpipe and close.
