Buying and evaluation criteria for home air conditioners
In order to find the most suitable air conditioner for you among the huge selection, there are features you can look out for.
The best way to compare air conditioners for your home is with these criteria:
In this section we present the most important criteria in detail.
Make sure you check whether you need a permit for your air conditioner. With a split air conditioner, part of the unit is mounted outside on the wall of the house. This can lead to disturbances and visual changes.
Whether you need to get a permit varies from region to region. To be on the safe side, contact the responsible building authorities before buying your air conditioner.
If you are only renting the flat, you must obtain a permit from your landlord. If you are the owner of an apartment building, talk to your homeowners' association and neighbours before installing the air conditioner.
Before you buy an air conditioner for your home, take a closer look at the technical data. The following points must be considered:
|Cooling capacity||Your required cooling capacity is related to the room size of the room. The larger your room, the higher the cooling capacity. Cooling load specifications are watts (W/h), kilowatts (kW/h) or British Thermal Unit (BTU/h).|
|Operating length||Not all air conditioners may run continuously.|
|Watt||The wattage shows you how much electricity your new air conditioner uses.|
Make sure that you buy an air conditioner with sufficient cooling capacity. It is also important to note that split air conditioners are more energy efficient than monobloc air conditioners.
An air conditioner cools your room for several hours. Check the decibel rating (dB) before you buy. Loud air conditioners quickly become a nuisance. A good air conditioner averages between 20 and 50 decibels.
20 decibels is comparatively as loud as the ticking of a clock. Birdsong or soft radio music can reach 50 decibels.
Certain home air conditioners have a night mode. This makes the air conditioner so quiet that you are not disturbed while sleeping. It is advisable to invest in a good product.
Probably the biggest problem with air conditioners is that they are harmful to the environment. In fact, it's twofold - the power consumption and the refrigerant. The Total Equivalent Warming Impact (TEWI) is the indicator of how much greenhouse gases are emitted.
Good technology as well as regular maintenance counteract electricity consumption. The inventory technique is a helpful method and is now standard in Europe. This adapts the cooling capacity to the existing room temperature.
The chemicals in refrigerants are harmful to the environment. However, they only become a climate factor when they leak from the air conditioner, for example because of poor installation or leaks. Even a small amount has an enormous impact on the climate.
If environmental friendliness is important to you, pay attention to the energy efficiency class and the chemicals in the refrigerant.
A user-friendly refrigerator is not only fun and comfortable, it also has a positive effect on the climate. This includes the remote control, the night mode and the temperature setting.
The remote control allows you to regulate your air conditioner from anywhere. In some cases, you can even control the air conditioner via smartphone. This saves you having to go to the air conditioner.
Some air conditioners have a night mode so that you can sleep at night without being disturbed by noise. The room continues to be cooled at a very low and quiet level. This improves the quality of your sleep.
People's temperature sensations are different. Therefore, it is practical if your air conditioner has a temperature controller. Your room will then be cooled as desired.
The size and weight of your new air conditioner should be considered before you buy it. A large air conditioner cools faster than a small one. But it can also be a nuisance because it takes up a lot of space.
If you have a mobile monobloc air conditioner that you will use in several rooms, it must not be too heavy. After all, you have to carry it from one room to the next.
Decision: What types of home air conditioners are there and which one is right for me?
When choosing an air conditioner for your home, there are two alternatives to choose from:
|Monobloc air conditioner||handy, mobile||high power consumption|
|Split air conditioner||efficient, quiet||cannot be installed alone|
Every air conditioner has its own advantages and disadvantages. Depending on your living situation and personal feelings, it may be more profitable for you to choose a monobloc or split air conditioner. To help you decide, we present both alternatives in more detail.
Guide: Frequently asked questions about home air conditioning answered in detail
What is a home air conditioner?
- Monobloc air conditioners
- Split air conditioners
Air conditioners are used to cool the air in our four walls. This makes the summer heat more bearable. The warm air in our rooms can be converted into colder air by various methods. In summer, ventilation usually brings nothing but even hotter air.
Split or monobloc - Which air conditioner is better for me?
- Split air conditioner
The split version of an air conditioner is composed of two parts - the outdoor unit and the indoor unit. The outdoor unit consists of the cooling compressor, which cools the air. From there, the cold air enters the indoor unit and thus your home. The two parts are connected with a hose.
With the split air conditioner, both components are permanently mounted. For outdoor installation, the regional building regulations must be observed and, if necessary, the necessary permits must be obtained.
- Monobloc air conditioner
The monobloc air conditioner consists of only one part. This air conditioner is mobile and offers fast and uncomplicated cooling of the rooms. Monobloc air conditioners are available with and without an exhaust hose. The hose is simply hung out of the window.
Therefore, before you buy an air conditioner, think carefully about the important criteria you want it to fulfil. Monoblocs, but also split systems have their own advantages and disadvantages.
For which air conditioners do I need a permit?
A permit may be required because the external block of the air conditioner involves a change to the facade of the house. In principle, the installation of one's air conditioner is permitted if technical safety is guaranteed, the unit visually matches the façade and there is no disturbance of the peace.
What alternatives are there to home air conditioners?
|Alternative||How it works|
|Fan||The fan generates a strong air flow that only cools the air in front of it. It is not suitable for cooling an entire room.|
|Evaporative cooling||For this, a wet towel is hung over the open window. The evaporation cools the air in the room.|
|Water spray||With the water spray you cool down your body by spraying the water on your arms and legs. Alternatively, you can use a wet wax cloth.|
|Humidifiers||Humidifiers work in the same way as the evaporative cooling technique. Cold water is put into the air to increase the humidity in the room.|
|Sun protection film||The sun's rays hitting the window do not reach the room through the sun protection film. This keeps the room pleasantly cool.|
The air conditioner achieves the best cooling performance of these 6 variants.
How much does a home air conditioner cost?
- Monoblocair conditioners: 100 - 800 euros
- Split air conditioners: 500 - 2,250 euros
The costs for installation, electricity and maintenance must not be forgotten.
To help you calculate the cost of electricity, this video explains how it works. This way you can easily calculate your potential costs of operation.
What capacity should my air conditioner have?
- Watt (W)
- Kilowatt (kW) = 1 kW/h corresponds to 1000 W/h
- British Thermal Unit (BTU) = 1,000 BTU/h correspond to 293.071 watts
To determine what cooling capacity your new air conditioner should have, there is a simple rule of thumb:
|Little||Room area in square metres x 60 watts|
|Much||Room area in square metres x 100 watts|
Your room has a size of 80 square metres and a high solar radiation. The calculation for the appropriate power is 80 square metres x 100 watts = 8,000 watts. You should therefore buy an air conditioner with a cooling load of at least 8,000 watts.
The second rule of thumb is calculated with cubic metres
- Room volume in cubic metres x 40 watts
Your room has a size of 80 square metres and is 2.5 metres high. The calculation for the appropriate power is 80 square metres x 2.5 metres x 40 watts = 8,000 watts. So you should get an air conditioner with at least 8,000 watts cooling load.
How do I clean my air conditioner at home?
- Preparation: Switch off your air conditioner and unplug it from the wall socket.
- Remove dust: The quickest way to remove coarse dirt is with a hoover.
- Clean the filter: To prevent bacteria from forming, remove the filter and wash it thoroughly in warm soapy water. The instructions tell you how to remove the filter.
- Drying: First dry the filter with a towel and then let it air dry completely. The filter must not be installed wet.
The hose and the condenser are best cleaned with the appropriate cleaning agents. You can also buy these from the manufacturer. In the case of monoblocs, condensation water also collects. The condensation must be removed regularly.
What do I have to pay attention to when maintaining my air conditioner?
The dust filter should not only be cleaned weekly, but replaced annually. It is important that the condensation water tank and the hose are cleaned.
