Review of the split system Hyundai H-AR21-09H: a hearty device with premium class claims

As a budget option for an air conditioner for small and medium-sized rooms, the Hyundai H-AR21-09H split system is suitable - a unit with good operating parameters and a variety of functionality.

Do you have doubts about choosing the right household climate control equipment? An air conditioner review and expert assessment will help you decide on a purchase.

To understand how well the Hyundai H-AR21-09H model corresponds to the task of maintaining the desired climate in a particular room, you need to delve into its technical parameters, analyze the pros and cons, and also compare the characteristics of the unit with similar competitors’ devices.

Basic parameters of the air conditioner

The technical characteristics of any purchased split system must correspond to the room and operating conditions. You also need to pay attention to the main modes and additional features in order to evaluate the ease of use of the device and the sufficiency of functionality.

Specifications and Dimensions

The H-AR21-09H air conditioner has a cooling output of 9043 BTU and a heating output of 9281 BTU. Maximum air flow of the indoor unit – 450 m³/hour. Split systems with such parameters can serve rooms under standard conditions up to 25 m², which is written in the user manual.

Here you need to understand that the mark “under standard conditions” means that the calculations considered a certain model room with a height of up to 2.6 m, good thermal insulation and the absence of intense air flow with a higher or lower temperature. Read more about how to correctly calculate the power of an air conditioner. Further.

One of the sources of excess heat is wide windows with southern or southwestern exposure. If they are present, it is necessary to either install a more powerful air conditioner or glue a reflective film to the glass

In real conditions, if the difference between the street temperature and the temperature required in the room is large, the windows have poor thermal insulation or there is air flow from other rooms, then the value of the room area that this air conditioner can efficiently serve must be reduced to 15-20 m².

The Hyundai H-AR21-09H model corresponds to energy efficiency class “A”.The rated current for cooling and heating is 3.6 A and 3.3 A, respectively, which makes it possible to easily connect such a low-power device to the electrical circuit of a living room.

The maximum permissible length of the route between the indoor and outdoor units is 10 meters, and the height difference is 7 m. This makes it possible to vary the installation locations of both parts of the split system. The fitting for connecting the tube on the external unit is located on the right, and the outlet is from indoor unit can be arranged in both directions.

The declared maximum noise level of 33 dB allows you to install a split system in offices, bedrooms and children's rooms. The dimensions (69 x 28.3 x 19.9 cm) and weight (7.3 kg) of the indoor unit are typical for devices of this power, so their installation is simple.

The design of the indoor unit of the H-AR21-09H model is unremarkable. White color fits well with almost any interior, and the display can be turned off

The air temperature that this air conditioner can produce lies in the usual range for such devices from 16°C to 32°C. Cooling can be operated at temperatures up to 47°C in the area of ​​the external unit (that is, outside the window), and heating can be operated from 0°C.

Modes and additional functionality

In total, the H-AR21-09H air conditioner has 5 operating modes:

• Heating. Raising the temperature in the room to the set value.
• Cooling (Cool). Reducing the temperature to the set value.
• Automatic (Auto). The air conditioner maintains the air temperature in the range of 23±2°C, starting heating or cooling mode depending on the situation.
• Dry. Removing excess moisture from the air. In this case, slight cooling occurs.
• Ventilation (Fan). Organization of air circulation without changing its temperature.

By switching the fan operating modes, you can achieve its rotation at low, medium and high speed. The speed of air circulation and temperature changes in the room depends on this. There is also an automatic selection function, which gives the device’s electronics the ability to determine the speed itself.

The quality of operation of the air conditioner in different modes depends not only on the parts and assembly, but also on compliance with the maintenance schedule of the device

The functionality of the H-AR21-09H model can be called almost minimal:

• Rotate the dampers vertically (Swing). Changes the direction of the outgoing air flow.
• Turbo mode (Turbo). Turns on maximum cooling or heating.
• Timer. Sets the time for automatic switching on or off of the split system.
• Sleep mode. After 1 hour it lowers the temperature by 1°C, then again and then stabilizes it.
• Self-cleaning procedure (iClean). Within 30 minutes, he carries out manipulations to clean the indoor unit from dust.
• Auto-drying procedure (Anti-fungus). Removes moisture from the indoor unit.
• Display. Turns the display on the front panel of the unit on or off.

The ionization function declared by the manufacturers works constantly and cannot be turned off from the remote control.

Pros and cons of the H-AR21-09H model

For each equipment, you can highlight properties typical for devices in this price category, as well as positive and negative qualities of a particular model. The device in question from Hyundai was no exception.

Typical options for this price range

Split systems in the price range of 15-20 thousand rubles are equipped with a rotary compressor.Now all models with inverter type are much more expensive. Motors operating on the basis of outdated technology, of course, have disadvantages compared to more advanced competitors, but they are cheaper.

Rotary compressors under the Toshiba GMCC brand occupy first place in the world in terms of sales. Finding components for them is easy

For air conditioners with a capacity of about 9000 BTU and a rotary compressor, the usual energy class is “A”. For more powerful ones there may be “B” and “C”.

Split systems with a budget price are usually limited to a remote control and a user manual. External block fastenings are never included in the kit, since the installation system for brick, concrete and wooden walls is different. There are also no tubes for transferring freon and gas, since their length depends on the position of the internal and external parts relative to each other.

Companies that install air conditioners always have fasteners and tubes in stock. Sometimes such companies lower the price for advertising purposes, indicating only the cost of work without taking into account components. This should be taken into account when ordering installation.

Positive aspects of a split system

Despite the fact that both the assembly of the system and its main element - the compressor - were assembled in China, the presence of the Hyundai brand implies a longer warranty than for the products of any little-known company. If there is an opportunity to extend the seller’s responsibility for the performance of a budget air conditioner with a rotary engine, then it should be taken advantage of.

The remote control for Hyundai H-AR21-09H is standard and is suitable for several series of air conditioners from this company. Therefore, in case of loss or breakage, it is quite easy to find it on sale.

Many air conditioners produced in China differ from each other only in design and brand. Their equipment and functionality are the same, as evidenced by the unified control panels

For the Hyundai H-AR21-09H model, it is possible to purchase for an additional fee and connect a Wi-Fi module for remote control of the air conditioner. This opportunity is rare for budget devices, which is a significant advantage of the split system under consideration.

Negative features and obvious disadvantages

The housing of the external unit of the H-AR21-09H air conditioner is made of metal. In cheap models, its thickness is insignificant, and if the assembly was not carried out very well, then an unpleasant rattling sound occurs when the fans operate. When the windows are open for ventilation, it can disturb both the owners of the premises for which the split system operates and the neighbors.

For quieter operation of the external unit, it is necessary to unscrew the fastening bolts, lay sound insulation (foam rubber or polystyrene) between the contacting parts and reassemble the housing. It is prohibited to make a box around the device, as this will interfere with heat transfer.

The following video will tell you about the noise of the external unit:

Using the control panel, the dampers can be moved to adjust the air flow vertically. Variation of the horizontal direction can only be done manually. Naturally, from a safety point of view, this can only be done when the air conditioner is not working.

The power cord is on the right, it is short and non-removable.This creates a problem if there are no outlets nearby: you will have to either use an extension cord or increase the length of the wire yourself.

Connecting an air conditioner through an extension cord will look ugly. It is better to increase the length of the cable and run it to the outlet secretly or in a box

The body of the indoor unit often contains multi-colored stickers that will not fit into any room design. What makes the situation worse is that they are difficult to peel off without leaving a scratch.

Comparison with common competitor models

The cost of the H-AR21-09H air conditioner fluctuates around 15-19 thousand rubles, if you do not take into account various promotions. In the same price range, three common models with the same recommended maximum room area were selected and a comparison was made based on standard characteristics for split systems.

Competitor #1 - Aeronik 09HS4

The model of the Australian brand is assembled at the Chinese plant of the GREE Corporation.

Specifications:

• cooling power (W) - 794;
• energy consumption class - “A”;
• compressor - rotary (Gree);
• Max. noise (dB) - 40;
• internal dimensions block (WxHxD, cm) - 74.4 x 25.6 x 18.5;
• internal weight block (kg) - 8.

This model differs from the Hyundai H-AR21-09H for the better in the compressor manufacturing plant and assembly. Among air conditioner service and repair specialists, Gree is rated higher than GMCC.

Also, the advantages include a multi-stage filtration system and the ability to maintain the temperature in the room when heating from 8°C (while permissible outdoors is from -7°C and above). The latter is often used to create a mode in which heating pipes will not defrost.

But still, the Aeronik 09HS4 model costs slightly more than the Hyundai H-AR21-09H.

Competitor #2 - Electrolux EACS-09HPR/N3

A product of a Swedish brand, assembled at the plant of the Chinese state company Hisense.

Specifications:

• cooling power (W) - 822;
• energy consumption class - “A”;
• compressor - rotary (Rechi);
• Max. noise (dB) - 28;
• internal dimensions block (WxHxD, cm) - 71.7 x 30.2 x 19.3;
• internal weight block (kg) - 8.

On the positive side, it is distinguished by the presence of a deodorizing (antibacterial) filter and a long route for systems of this power: 20 meters. The delivery set includes a set of fasteners for the indoor unit.

Rotary compressors produced by Rechi Group are also considered to be of higher quality than those of Midea, which is found on the Hyundai H-AR21-09H.

Among the disadvantages are the lack of an air ionization system and a larger indoor unit than its competitors.

Competitor #3 - Green 09HH2

A completely Chinese model, produced by Green at the Hisense plant.

Specifications:

• cooling power (W) - 794;
• energy consumption class - “A”;
• compressor - rotary (Gree);
• Max. noise (dB) - 40;
• internal dimensions block (WxHxD, cm) - 74.4 x 25.6 x 18.5;
• internal weight block (kg) - 8.

This model is no different from the Hyundai H-AR21-09H, except for the design and a more reliable compressor manufacturer.

Conclusions and best offers on the market

Hyundai H-AR21-09H can be described as a typical budget air conditioner with typical functionality for residential and office premises up to 25 m2². What makes it stand out from a number of similar models is its ability to be controlled remotely via Wi-Fi.

The installed Toshiba GMCC compressor is not the best engine in terms of noise and reliability, so if you plan to use the split system intensively, then it is better to pay attention to the slightly more expensive models of competitors, which are described above.
