How can you install air conditioning

Installing air conditioning: the most important questions and answers

As the outside temperature rises, the temperatures inside also climb higher and higher. You know the consequences for sure: poor sleep, reduced ability to concentrate, etc. The installation of an air conditioning system can help.

Here you will find the best tips and tricks for installing an air conditioner. Among other things, we will explain to you how an air conditioning system works, explain the different types of air conditioning systems and tell you the costs you will have to pay for purchasing and installing an air conditioning unit.

the essentials in brief

  • Basically, a distinction can be made between two different types of air conditioning: monoblock units and split air conditioning systems. While the former only ever cool one room, the latter can also be installed in several rooms.
  • The installation of an air conditioning system should be well planned. Among other things, you should know the amount of cooling required and the general energetic state of the building in which the air conditioning is to be installed. The air conditioning system should match the building in terms of size, type and performance.
  • In any case, you should get help from an air conditioning specialist for installing an air conditioning system. In particular, you should leave the installation of a split air conditioning system, which requires the opening of a wall, to a specialist.

Background: What you should know about installing air conditioning

Before you decide to install an air conditioner, you should deal with the following questions that we have answered for you. We'll tell you what things to keep in mind when installing an air conditioner.

How does air conditioning work at all?

Basically, all air conditioners work on the same principle: They suck in warm room air and cool it down with the help of a special refrigerant. The cold air is finally released back into the room.

There are mainly four components of the air conditioning system involved in this process:

  • compressor: This is where the air conditioning refrigerant is compressed. The compressor draws in the refrigerant in gaseous form, whereby the pressure is increased enormously.
  • Condenser: The refrigerant is pressed by the compressor into the condenser / condenser. The still warm refrigerant is cooled down there with the help of outside air. It gives off its waste heat to the colder air in the immediate vicinity and begins to condense. The refrigerant changes its form from gaseous to liquid.
  • Expansion valve: The liquid coolant is fed into the evaporator via its own line via the expansion valve.
  • Evaporator: Here the liquid refrigerant is evaporated with the help of the ambient heat or the room temperature. For this process, the warm room air is sucked in via a fan and passed through the evaporator. In return, the cooled air is blown into the room.

The resulting air is released into the room until the room temperature has reached the desired level. The refrigerant, which is now gaseous again, flows back into the refrigeration circuit without any loss.

What types of air conditioning are there?

If you want to install an air conditioning system, you have the choice between different types of air conditioning systems:
  • Monoblock devices
  • Split air conditioners

In the following, we will introduce you to the different types of air conditioning and list the respective advantages and disadvantages.

Monoblock devices

Monoblock air conditioning units represent the simplest model of an air conditioning system. They consist of only one housing in which the compressor and cooling fins are located.

The housing serves as a heat exchanger that transfers the room heat to a special refrigerant. The refrigerant circulates in a closed circuit. Heat is usually released outside via hoses that lead outside through an opening in the wall or a slightly open window.

  • Can be set up flexibly in the room
  • manageable acquisition costs
  • Annoying sounds
  • Inefficient operation of devices without an exhaust hose
  • Higher power consumption for devices with an exhaust hose

Monoblock devices offer you a cheap and easy-to-install solution if you would like to own an air conditioner. The great advantage of a monoblock device is that it does not require any additional installation in the apartment.

However, the noise from the system can be a disadvantage. In addition, a lot of outside air enters when the exhaust hoses are in open windows, which increases the cooling load and thus increases running costs.

Split air conditioners

So-called split air conditioning systems are recommended for long-term use of an air conditioning system. They work exactly like monoblock devices, but consist of two separate housings: an outdoor unit with a compressor and an indoor unit that cools the room air.

This variant eliminates the annoying hoses in the windows. The two units can be connected via cables that run through two thin holes in the outer wall.

  • High cooling capacity possible
  • high efficiency
  • Less noise pollution
  • Connection of several indoor units with one outdoor unit is possible
  • Higher acquisition costs
  • Not flexible to use

If you decide to install a split air conditioning system, you will benefit from a quiet and efficient system. Since split units have access to cool outside air, they achieve higher levels of efficiency and can therefore work with less energy than monoblock units.

Another advantage is that several indoor units can be connected to one outdoor unit. This gives you the option of cooling several rooms with just one system in summer.

In addition, split systems can function as heat pumps in winter, so that you can even use the technology to heat the respective rooms.

What does the installation of an air conditioner cost?

The cost of purchasing and installing the air conditioning differs depending on the type of air conditioning.
Type Price range
Monoblock devices approx. 300-800 €
Split air conditioners approx. € 800-2,000

If you choose a monoblock device, you can expect costs of around € 300 to € 800, depending on the manufacturer. In addition, there are costs of around 20 to 50 € for a window seal, which prevents the inflow of warm air when the exhaust air hose leads outside through an open window.

When installing a split air conditioning system, you can expect costs of around € 800 to € 2,000.

The installation of such a system always involves expensive wall openings. If you want to cool several rooms with a multi-split system, the costs are around 2,000 to 5,000 €.

If you have decided to install an air conditioning system, we recommend that you save costs by lowering the cooling load as much as possible. You can do this, for example, if you keep blinds and curtains closed during the sunny hours. Your air conditioning will then have less to do and power consumption will decrease.

Who can install air conditioning?

Even if manufacturers advertise that the installation of the air conditioning system should be possible without outside help, we recommend that you go to an air conditioning specialist. In particular, you should leave the installation of a split air conditioning system, which requires the opening of a wall, to a specialist.

An air conditioning specialist saves you problems, because he guarantees that the components of the air conditioning system are optimally matched to one another. This should always be the case because, for example, if the lines are too long, the refrigerant cannot circulate properly.

What is the cooling capacity of a built-in air conditioning system?

The cooling performance of an air conditioning system depends on several factors and depends primarily on the local conditions.

For example, the cooling capacity must be correspondingly high if there are many windows, exterior walls and / or electrical devices in the room with air conditioning.

A specialist can help you dimension your air conditioning system precisely by calculating the cooling load.

In addition, all the heat yields that the air conditioning system has to compensate for in order to bring your living space or rooms to the desired temperature are added.

For a simple estimate, many manufacturers also indicate the room volume that can be cooled with the appropriate air conditioning system.

What should you consider when installing an air conditioning system?

Our tip to you is to plan the installation of an air conditioning system well in advance. That means dealing with questions such as the amount of cooling required in advance.

You should think about whether only a single room, individual rooms in particular, or all rooms should be cooled.

The air conditioning system should match the building in terms of size, type and performance.

You should also know the general energetic state of the building in which the air conditioning is to be installed and include it in your calculations. It is best to get detailed advice from an appropriate specialist.

Finally, it is worth checking again whether you have taken all other measures to avoid heat in your living space. If this is the case, the installation of an air conditioning system can prove to be useful.

Installing an air conditioning system: The 3 best tips for installing an air conditioning system

Should you decide to install an air conditioner, we would like to give you the three best tips below, which should make the assembly of your air conditioner easier for you.

Get support from an air conditioning specialist for installing an air conditioning system

We recommend that you always consult an air conditioning specialist for the installation of your air conditioning system. Especially if you decide on a split air conditioning system that requires a breakthrough in the wall, you should leave the installation of the system to a specialist.

If you don't want to leave all the work to a specialist, you can already safely mount the indoor unit of the air conditioning in your living space to be cooled. You can also install the outdoor unit in front of the house (e.g. on the floor or on consoles on the outside wall).

Once these components have been installed, it is the turn of the specialist. This ensures that the refrigerant lines for the air conditioning system are properly laid. To do this, lines are routed from the indoor unit through the outer wall to the outdoor unit.

The air conditioning specialist has better tools and more experience in building air conditioning systems. With its help, you can avoid rookie mistakes and save time.

To start up the air conditioner, the indoor and outdoor units must be connected to the power supply. Again, you should have the work done by a professional.

Be aware of all the advantages and disadvantages of installing an air conditioner

Of course, air conditioning offers a number of advantages, above all pleasant temperatures in the living room, even on hot summer days. Thanks to the innovative technology, your living spaces stay at the right temperature, no matter how warm it is outside.

A pleasant indoor temperature in turn has other advantages, such as improved sleeping and living quality. Even on hot days, you can concentrate better thanks to the cooling effect of the air conditioning.

However, installing an air conditioning system can also have disadvantages, which you should find out about in advance. This includes, for example, the purchase and installation costs of an air conditioner. You should also be aware of the additional electricity costs.

If the technology is set incorrectly, drafts can occur that reduce living comfort. In addition, monobloc devices in particular can be noisy, which is why you cannot always easily install them where you want.

In the following we have listed the possible advantages and disadvantages of a built-in air conditioning system again.

  • Pleasantly cool living spaces
  • Higher quality of living
  • Healthy sleep
  • Greater ability to concentrate during the day
  • High acquisition / assembly costs
  • Noises from the system
  • Dry air in living spaces
  • Drafts caused by incorrect setting of the technology

Talk to your landlord before installing an air conditioner

If you want to install split air conditioning in a rented apartment, you as the tenant have to ask the landlord for permission. You can only install the air conditioning with the consent of the landlord and we recommend that you have your consent given in writing.

The consent of the landlord is required to install an air conditioning system.

But even before installing a monoblock device, we advise you to get the permission of your landlord so that you don't get into trouble afterwards.

For example, the exhaust air hose of the monoblock air conditioning system could already be a visual impairment for some.

In addition, neighbors could be disturbed by the noises of the system and / or the development of heat if the air conditioner is on the balcony or the like. Talk to your landlord before installing an air conditioning system and save yourself unnecessary problems.

Conclusion

It can be said that there are a number of things to consider when planning to install an air conditioner in your living space. Starting with the different types of air conditioning systems and their respective advantages and disadvantages to the different cost factors.

The fact is that a built-in air conditioning system keeps your interiors pleasantly cool even on hot summer days and thus improves the quality of sleep and living many times over. Those who accept the high acquisition / installation costs of an air conditioning system benefit from these advantages and can say goodbye to sleepless summer nights.
