How to choose your Klarstein air conditioner

The air conditioners in the Klarstein catalog are not all alike. Which model is right for you depends on a number of factors. In this section, we will show you all the criteria to consider when selecting a Klarstein air conditioner.

#1 - Cooling capacity

The cooling capacity of a Klarstein air conditioner is measured in British Thermal Units (BTU) per hour (BTU/h). To ensure high efficiency, choose an air conditioner with a BTU level designed to fit the size of your room or space. If you use a Klarstein air conditioner that doesn't have enough BTU/hr to cover a large room, it will run longer to try to bring the temperature down.

In the process, it wastes energy. On the other hand, an air conditioner that has too much cooling capacity for your space will cool it, but the unit doesn't remove as much moisture from the air as a unit with the proper cooling capacity should. This will make your room feel damp and clammy.

To find the right cooling capacity for your room, determine the square footage of your space. Then use the chart above to find your ideal BTU measurement.

#2 - Energy efficiency

Air conditioners are energy guzzlers, Klarstein's are no exception. Buying a cheap model requires taking a serious look at the energy efficiency ratio abbreviated as EER or Energy Efficiency Ratio. This is a standard measure for comparing home appliances. It is obtained by dividing the BTU power by the electrical energy consumed.

Clearly, the higher the EER, the less energy the air conditioner consumes. The manufacturers translate the EER ratio into an energy class on a label placed prominently on the unit. This includes A+++, A++, A+, all the way up to D. However, this is not a 100% reliable indicator, but is still a significant criterion.

#3 - Additional features

Changes in technology have made keeping your home cool easier than ever, and while all the fancy features come at a price, they might beworth it.

  • Presence Sensor: Some Klarstein air conditioners have built-in sensors that can detect when someone is in the room and when the room is empty, so the air conditioner can adjust accordingly to save energy. Some air conditioners are even able to direct the air to the detected presences so it doesn't have to work hard to keep you cool.
  • Sleep Mode: Sleep mode is an option found on many modern Klarstein air conditioners. Once activated, this feature will allow the air conditioner to gently adjust the room temperature to a comfortable level while you sleep.
  • Air Filter: Most Klarstein air conditioners these days are equipped with air filters that remove odors, smoke and germs from the air. These air conditioner filters will require occasional cleaning.
  • Dehumidifier mode: Almost all Klarstein air conditioners have the basic operating modes: automatic, cool, heat and fan. But only some models have a dehumidifier mode. Dehumidifiers remove moisture from the air, helping to reduce humidity in an energy-efficient way.
  • Wi-Fi connectivity: Many Klarstein air conditioners can connect to your home's wireless network so you can control the air conditioner via an app from your smartphone. This is a handy feature if you're at work and want to turn it on before you get home, or if you're at home and just misplaced the remote.

#4 - Noise level

Thenoise emitted by the Klarstein air conditioner is an important parameter, on which your comfort will depend. Be aware that the packaged air conditioner is the loudest, with a sound level between 50 and 70 dB. The split air conditioner has a sound level between 45 and 55 dB. If the device is to be installed in a room, choose a model with the silent option. With this feature, the noise level is gradually reduced to below 20 dB.

A noisy indoor unit can interfere with your activities, conversation or sleep. A noisy outdoor unit may disturb you (if it's too close to a bedroom or living room window) or your neighbors, so think carefully about where you place the outdoor unit.

#5 - Ease of use

Unless you choose a Klarstein mobile air conditioner, all air conditioners should only be installed by a licensed professional installer who is qualified to handle refrigerants. This ensures that everything is done correctly, safely and that you remain covered by the manufacturer's warranty. The amount you pay for installation will depend on factors such as where you live, the type of system you are installing and the ease of the job.

Klarstein mobile air conditioners shouldn't be too much of a hassle to install, otherwise they wouldn't be able to credibly claim the "mobile" label. The main thing you'll need to worry about is hooking up the window kit and the outdoor unit. Your quiet mobile air conditioner should come with clear step-by-step instructions on how to do this.

When to buy an air conditioner?

Air conditioners are not cheap appliances, so you want to make sure you get the best price. But when is the best time to buy one? In the summer, when business competition is strong, or in the winter when demand is low? Well, despite the "bargains" you'll see in the summer, it turns out that winter is generally the best time to buy a new air conditioner, especially around July and August, as appliance sellers are more likely to lower prices to clear their inventory.

That said, the best time to buy is not necessarily the best time to install. Businesses often find themselves overworked in the winter, especially in areas where there is a high demand for heating and cooling installations. You will generally find that the best time to install an air conditioner is during the transitional seasons of fall or spring.

How do you install a window air conditioner?

 class=

Most window air conditioners fit standard windows that you can raise or lower. Carefully measure the interior dimensions of the installation window to ensure you select the right air conditioner. Window air conditioners are also heavy, so it's important to have someone help you with the installation.

Before installing a window air conditioner, keep in mind:

  • Installing an air conditioner in a shaded window will help it work more efficiently. Choose a north-facing window, as it will be in the shade most of the day.
  • The window you select for installation needs an appropriate power outlet nearby. The manufacturer may specify that you plug the unit directly into the outlet without an extension cord. The outlet circuit must be able to handle the electrical load of the air conditioner.
  • Contact a licensed electrician if you have any doubts or questions or to determine what parts or accessories you may need to complete the job.

The different types of Klarstein air conditioners

There are different types of air conditioners on the market, each with its own advantages and disadvantages. Here are the main types of air conditioners available in the Klarstein catalog.

Klarstein mobile air conditioners

Mobile air conditioners, also called packaged air conditionersMobile air conditioners, also known as portable air conditioners, offer maximum flexibility, as they can be easily moved and are not bound by the outdoor unitas in the case of wall-mounted split air conditioners. Unlike a fixed air conditioner, in a mobile air conditioner, the exhaust pipe is not necessarily installed on the wall and can be moved from window to window.

Although the performance of Klarstein mobile air conditioners is inferior to that of split models and they tend to be noisier, the packaged mobile air conditioners are a good solution for home and small office environments, as they are more versatile.

Klarstein window air conditioners without outdoor unit

Klarstein air conditioners without an outdoor unit are the ideal solution if you need to cool your room without affecting the aesthetics of the façade. In particular, it is the priority choice of building technicians to preserve the aesthetics of historic buildings, but there are few models on the market, costs are uncompetitive and performance is inferior to split models with two units. The motor will be placed in the room, not outside.

Klartein fixed split air conditioners

TheseKlarstein air conditioners consist of an external compressor connected to the internal element mounted on the wall in the room to be cooled. Some models are only used for cooling while others are equipped with a heat pump that also heats the air in winter. Air conditioners with heat pumps perform two functions: cooling the room and heating the air. This means that by installing a heat pump air conditioner, you can provide ideal climate management for temperature, humidity, ventilation and air cleanliness with one product.

Klarstein mobile air conditioner or air cooler?

Klarstein mobile air conditioner

There are two main types of Klarstein mobile air conditioners: packaged air conditioners and split air conditioners. Single-package systems house all the rooms in a single unit. They are the cheapest air conditioners available and are ideal for use in conjunction with a central air conditioning system. Portable split air conditioners consist of two units: the outdoor unit contains the compressor and condenser while the indoor unit contains the ventilation system. The two units are connected by pipes. Although split air conditioners are more expensive to purchase, they are quieter than single unit models because the motor is kept outside the property.

Air cooler

Air coolers don't "condition" the air so to speak, but they do cool it as the name suggests! These devices are a bit like fans, except that they have a water tank that can also be filled with ice. Air coolers work by drawing in warm air and sending it through a cooling pad that is kept constantly moist. As the water evaporates, the air is cooled and returned to the room via an internal fan. Although less expensive than portable air conditioners, these units are much less effective at cooling the room air. However, they can lower the room temperature by a few degrees.

Verdict

An air cooler will always be cheaper to buy than an air conditioner. They do not emit harmful gases and require little maintenance. However, an air cooler does not have the ability to regulate the room temperature with great precision. In terms of energy consumption, air coolers do not use much electricity. Klarstein mobile air conditioners are a bit more energy intensive. In the end, it all depends on your real needs, but also on your budget.

Why buy a Klarstein air conditioner?

For better air quality

Klarstein air conditioners help circulate and filter the air. The presence of filters also helps remove pollutants from the air you breathe. This is important, especially for people who suffer from conditions such as allergies and asthma. In short, a Klarstein air conditioner helps reduce the irritants that cause these health problems.

To enjoy a better quality of sleep

It's clear! You should always get a good night's sleep, but it can be difficult to sleep well if your room is too hot or too cold. A properly functioning Klarstein air conditioner can help cool down a hot night. Your body will undoubtedly adapt to the temperature changes and you will get enough sleep.

To reduce the risk of dehydration

High temperatures mean excessive sweating. When you sweat profusely, you actually lose a lot of water from your body. It's healthy to stay hydrated even in extreme conditions. If you're indoors at home or at school, it's wise to leave the Klarstein air conditioner on.

For greater safety at home

When you air condition your home with a Klarstein air conditioner, you also keep your doors and windows closed. This increases the security of your home, as it is difficult for someone to break into your home when all the windows and doors are closed. With a working Klarstein air conditioning unit, you don't need to open your windows or door to condition your home.

To prevent overheating of electronic devices

You should keep in mind that a Klarstein air conditioner will help you save extra money on electronics repairs. Too much heat can also cause serious damage to electronics such as loss of data or shortening their lifespan. If your workplace has computer servers, they can be completely damaged by excessive heat. Therefore, you need to cool the room where these devices are stored by installing the best air conditioning unit.

Tips

Consider your budget

While initial purchase costs may vary, it's worth considering the ongoing operating costs of the Klarstein air conditioner you choose. More energy-efficient models can reduce the amount of money you'll have to pay each time you get an electric bill. More energy-efficient models are also better for the environment.

Determine your usage

Reverse cycle air conditioners are suitable for both home heating and cooling and are especially useful in climates that fluctuate between extremes. If you're unlikely to use your Klarstein air conditioner year-round, it may be a feature you can live without.

Maintain your Klarstein air conditioner regularly

Inaddition to the manufacturer's warranty, regular maintenance will inevitably increase the life of your Klarstein air conditioner. This will include, for example, cleaning or replacing the air filters as specified by Klarstein.

For a Klarstein window air conditioner, consider the window position

Awindow that is not centered on the wall can impair cooling efficiency. This is because the air must be directed toward the center of the room for optimal performance. Also consider sun exposure and whether or not the window needs to be caulked during installation.

Run your Klarstein air conditioner continuously

Many tests have proven that continuous operation of the air conditioner uses less energy than one-time use. In fact, an air conditioner that has already reached the desired temperature will reduce its cooling capacity. This will lower energy consumption, especially during hot weather.

FAQ

Portable air conditioner or stationary air conditioner: which one should you choose at Klarstein?

Klarstein portable air conditioners in general are less efficient than split wall air conditioners, because they are often monobloc. In addition to this, it is necessary to leave a space in the door or window, to place the hose for the heat to escape from the room, and this compromises the overall air conditioning of the room.

What is the right temperature for an air-conditioned room?

Theoptimal temperature, also not to exceed the acceptable consumption for a Klarstein air conditioner, is around 25 ° C, but it is always better not to go below 6-7 ° C compared to the temperature outside, because an excessive temperature difference can be dangerous to health.

How often should Klarstein air conditioners be maintained?

Forlarger systems with a fill volume of about 2.5-3 kg, maintenance is recommended once a year. For smaller units, a maintenance interval of 2 to 3 years is usually sufficient. This way the filter can be checked and replaced, if necessary. Maintenance is usually performed by air conditioning, heating and sanitation specialists. And the refrigeration technology of complex systems can also be checked regularly by an electrician.

Do the filters that Klarstein air conditioners have eliminate viruses and bacteria?

Thequestion here is whether the filters on Klarstein air conditioners are really useful for people with allergies. The important thing is to avoid water stagnation where bacteria could proliferate, such as legionella, but the risk of bacteria proliferation with Klarstein air conditioners is very low.
