Ac Maintenance Service

性禁区AC Maintenance Service Dubai:

What is the maintenance of air conditioning:

  • To extend service life
      • The lack of refrigerant gas and dirty heat exchangers greatly reduce the life of the compressor – the main element of the system
  • Air conditioning works at full capacity
      • In Middle East regions, like Dubai UAE, air conditioner heat exchangers are quickly polluted, which is why air conditioning blows with cold air.
      • The lack of refrigerant reduces the power of the system, because of what it will not cope with the cooling of the laid area of ​​the room
  • Reduce energy overruns
      • Air conditioning with a lack of refrigerant gas and dirty heat exchangers consumes more electricity than normal air conditioning
  • Damage Warnings
      • If you notice in time deviations in the operation of the equipment, you can save parts from failure 
      • For example expensive compressor when overheating
  • Smooth operation
      • Breakdowns occur at the most inopportune moment, it is better to eliminate them during preventive ac maintenance than in the heat, and wait for the arrival of the Ac Maintenance Companies

The durability of the air conditioner depends on :

  • conditions in which the air conditioner works
  • Installation quality
  • air conditioner manufacturer
  • Ac service

After-sales service minimizes the negative consequences of poor installation quality and poor environmental conditions.

How often do I need Ac Maintenance Service in Dubai?

This is influenced by the following factors:

  • clean air
  • how often do you use air conditioning
  • required degree of reliability ( cooling room or expensive equipment ) 

性禁区It all depends on how often the air conditioner is used and in what conditions.

But even if the air conditioner is clean in appearance and properly cools the room, this does not mean that everything is fine with it.

Ac Cleaning

Ac cleaning Dubai

Cleaning the air conditioner indoor unit:

  • Filter Wash
  • Evaporator treatment (internal heat exchanger)
  • Cleaning the fan impeller
  • Ac Drainage cleaning
      • drain pan
      • drain hose
      • drainage pump

Cleaning the external unit of the Air Conditioning system:

  • dry clean
  • high pressure water wash (karcher)
  • car wash

性禁区The cost affects:

  • Number of air conditioners (discount from 2 air conditioners)
  • Availability of air conditioning
  • (dismantling the ceiling, the release of the passage to the air conditioner)
  • Climber or aerial platform services
  • Night work

Ac Filter Wash

Dust coarse filters (grids, as many call them) are washed under running cool running water, drying is not required, moisture does not interfere with the operation of the air conditioner. The need for washing the filters can be determined by the presence of a layer of dust on them.

Ac Evaporator treatment

The evaporator is a coil of copper tubes with fins of thin aluminum plates – as in a car radiator, only the plates are thinner and more often located.

性禁区Evaporator processing types:

  • mechanical
  • chemical
  • antibacterial
  • high pressure washing

For mechanical Ac cleaning a special brush is used, which does not crush the ribs. It is used for heavy pollution.

性禁区Chemical treatment removes inorganic and organic contaminants from the evaporator – fats, soot layer, tobacco smoke particles, fine dust that accumulates passing through dust filters.

Sometimes, due to a layer of such dust, the air is completely not cooled when passing through the indoor unit. 

In case of contamination that cannot be removed by chemical means, the indoor unit is washed with a high-pressure washer – with a Karcher, with its dismantling and subsequent installation.

Antibacterial treatment of Ac will prevent the formation of fungi, mold and destroy the existing accumulations of bacteria in the air conditioner. Also, this measure will eliminate odors from the air conditioner.

For this purpose, special means are used, which are produced in aerosol cans, ready for use, or in the form of concentrates, which must first be diluted with water.

性禁区“Master of Cold” uses such tools for processing evaporators:

  • Easyclean
  • Easycare
  • Domestic means “Nanopirit”
  • Tophouse
  • Hydrocoil

All these tools have been tested and approved by manufacturers of air conditioners and condensate pumps.

Cleaning the fan impeller

With a small amount of contamination in Ac System, it can be cleaned with a brush, followed by chemical treatment.

If the contamination of the impeller is large, then it will have to be removed and washed.

Drainage cleaning

Gravity drain system

With this type of drainage, pollution often accumulates at bends or tapered areas. Effectively cleaned can be mechanically – purging with compressed gas. after that, it is necessary to spill the drain hose with water, preferably with the addition of chemical agents, as this will prevent the formation of mold and mildew, which also cause clogging of the drain hole and the hose.

Pump drainage system

Cleaning of this type of drainage system differs only in that it additionally has a float signal bath. It is necessary to monitor its purity most closely and regularly, since in the presence of dirt false alarms occur in it, which leads to the operation of the pump “dry” – this is the most common cause of the drain pump failure. The cost of replacing the pump is quite high, so we recommend regular cleaning of pump systems.

Ac indoor unit Cleaning

Dust filters (coarse filters) 

Dust filters are cleaned with cold running water, this procedure is available to any air conditioner user.

The frequency of washing the filters – in fact, on the frequency of use and the degree of air pollution. Learn what you need to clean the filter by opening the air conditioner panel – if the filters has accumulated a layer of dust, they should be washed under running water, if the contamination is not removed, it is recommended to use neutral cleaners.

Ac outdoor unit Cleaning

How necessary is this procedure?

Many people think that after the removal of dry brush “carpet” of poplar fluff and dust outdoor unit is completely pure and it is possible to finish the cleaning.

In fact, as it does not sound paradoxical, this “carpet” often does not interfere with the normal condensation of freon, only slightly delaying the passage of air through the edges of the condenser.

Particularly worsen the heat exchange particles of exhaust gases, grease and dust deposited on the inner surface of the ribs. Experts are well aware that when washing with high pressure water a clean-looking condenser, which even “shines through”, very dirty water flows out of it and, moreover, for a long time.

If your air conditioner is in the area of ​​exhaust emissions, increased dust formation and other air pollutants, it should be regularly washed with a high-pressure washer.

How to wash the Air conditioner in Dubai?

A condenser is needed for washing – a heat exchanger consisting of copper tubes with aluminum fins.

In order not to bend the edges of the water stream is required to direct strictly parallel to the ribs. To do this, direct the stream to the rear (or front) of the condenser and wash the entire surface evenly.

If the location allows, then this can be done with a simple straight nozzle, available in any wash set. But in most cases, this requires a corner nozzle, allowing to penetrate into the space between the wall and the outdoor unit.

Disassembling the case or washing the air conditioners on the fan side is not correct, it does not make sense.

Preparing Air Conditioner for hot weather in dubai

Work on the prevention of split Ac systems:

  • Cleaning the indoor unit: filters, housing, heat exchanger, fan
  • Cleaning the outdoor unit
  • Check leak detector refrigerant gas
  • Checking the pressure in the system and refilling the refrigerant (refrigerant gas)
  • Rolling compound pulling
  • Clearing the drainage system: drain pan, drain hose, pump
  • Wire pulling in terminal block
  • Checking the operating current of the compressor
  • Noise elimination
  • Check the control panel
  • Checking the air conditioner in all modes of operation

How often should prophylaxis be carried out?

It depends on such factors:

  • how often is air conditioning used
  • how clean is the air outside
  • whether quality air conditioning is installed
  • uptime criticality

性禁区It is clear that if the air conditioner is used around the clock and constantly, then it becomes dirty much faster than its counterpart, which is included only when necessary.

性禁区The more dust and dirt on the street and in the room, the more often it is necessary to wash the filters of the indoor unit (this is quite up to the owner of the air conditioner) and clean the heat exchangers of the indoor and outdoor units. This is especially noticeable in the season of “poplar fluff” – the outdoor unit can be covered with a dense “fur coat” in just a few days.

The better the consumables and tools, and the more professional the installation of the air conditioner, the less refrigerant gas will be leaked and the less ac gas refueling性禁区 will be needed.

If the air conditioner does not work for several days in the apartment or in the office, it’s unpleasant, but not critical, but if the air conditioner of the server’s cooling system breaks down, expensive equipment may fail, a break in the work of the whole department, loss of important data. It will already be quite critical and it is necessary to monitor the condition of air conditioners regularly in order to prevent split-system failure in time. 

Preparing for the winter season – conservation

性禁区Domestic split systems do not require mandatory preservation for the winter.

性禁区After receiving the inquiry/complaint, the Ac service team arrives at the call, diagnoses the malfunction and repairs the control board immediately on the spot.

Each Ac Maintenance Van has the necessary supply of basic radio elements and, in case it is possible, repairs the board on the spot.

性禁区The cost of the work will include: departure service crew and diagnostics, repair of the air conditioner board itself, removal and installation of the board with disassembly and assembly of the air conditioner.

Repair in the Ac service center

If on-site it was not possible to repair the PCB board, the repair team removes it and delivers it to the service center where the radio-electronics specialists restore its working capacity.

Specialists of the Ac service center in Dubai will identify the malfunction and repair the Ac PCB board in case of failure of the microchips, relays, and other radio components. In case there are no original parts, they will select a fully functional analog of reliable manufacturers.

It is also possible to  independently性禁区  bring a fee to our service center.

Why is the Air Conditioner noisy?

Is your Air Conditioner noisy?

Noisy Ac Maintenance Company Dubai

Noise from the indoor unit

Usually, the noise from the air conditioner appears several years after using the Ac without service, or even during its operation.

But there are also possible extraneous sounds immediately after the installation of the split system.

It is very important to correctly identify the source of the noise, after that, knowing the cause, it will be much easier to eliminate unpleasant sounds.

Causes of Ac noise:

Fan noise

    • fan bearing

      • during operation, a roar is heard, the fan stops immediately after shutdown, scrolls with a small

    • grazing

      • Usually in old air conditioners due to warping and deformation of plastics

    • grazing ice

      • details of the reasons for the formation and elimination of ice are described in the article

Buzz off

  • buzz is not loud, but prevents to fall asleep

  • common in cheap Chinese air conditioners

  • 性禁区problem is solved by replacing the power transformer

Hiss on power

  • the cause is the flow of refrigerant in the air conditioner tubes

  • manifests when the tubes break and the section narrows

  • also observed when clogged internal cavities tubes

  • after installation of used air conditioners

Air Conditioner vibration

  • 性禁区sometimes the air conditioner can vibrate very much, almost flying off the mounts on the wall

  • 性禁区the reason is the imbalance of the fan impeller

  • can fly off a balancing weight (like on car disks)

  • 性禁区more often the cause is severe contamination of the impeller – unbalancing occurs either because of the irregularity of the pollution along the length or after a piece of dirt flies off from a small area

Noise drainage pump

  • drainage pump starts to crack when it fails, in this case you need to clean or replace the pump

  • crackling will also occur when the air conditioner is idle for a long time, as the pump produces a crackling sound when it is dry, it will stop after a short cod

Noise from the Ac outdoor unit

Since the external units of air conditioners are installed in close proximity to the internal one, most often outside the window, therefore, the noise from the external unit sometimes gets in the way, especially at night, not only to the owner of the air conditioner, but also to his neighbors.

Causes of noise from the external unit

No vibration damping rubber gaskets

  • vibration dampers located between the brackets and legs of the air conditioner
  • they reduce the transmission of vibrations from the air conditioner to the wall

The mounting bracket bolts are in contact with the metal reinforcement of the reinforced concrete wall

  • 性禁区at the same time there is a feeling that the wall is vibrating

  • it is possible to eliminate only by drilling holes in another place (near) and moving the fixings

Compressor wear

  • after many years of operation and lack of maintenance, the compressor will have extraneous noises and vibrations

Fan noise

  • 性禁区grazing and foreign objects are often caught

  • ice grazing in heating mode

  • overtones from design elements

  • cheap air conditioners often vibrate lattice elements, covers

  • usually solved by removing them or by laying seals

  • do not be afraid to remove non-functional elements, they serve only for appearance and they are often saved

We have analyzed the main causes and ways of dealing with noisy air conditioners, but it is worth remembering that after many years of work, the equipment will not work as new, especially if the main body material is plastic.

Difference Between Inverter Air Conditioner and Classic Ac

Inverter Ac Maintenance Dubai 

This article is written to answer questions from air conditioners’ users, so that a simple person can understand the difference between inverter air conditioners and ordinary ones.

This is written on many resources, but most of them are a set of certain stamps and are aimed at persuading a person to purchase a more expensive inverter air conditioner性禁区 , regardless of the buyer’s needs.

Sometimes there are articles in which nonsense is written, compiled by a marketer rather than a technical specialist.

性禁区The authors are not particularly puzzled by the proof of the information given, they simply rewrite articles from each other.

The difference between inverter and “on / off” air conditioners

性禁区Structurally:

  • In the inverter there is an electronic power board in the external unit, in the classic there is no
  • Compressor motors have different operating principles.

Everything else – the type of electric motors of fans, the type of TRV, and other technical nuances depend on the model of the air conditioner性禁区 , and not on the method of power control.

By the method of power control:

  • Inverter – continuously adjustable power
  • On / off-air conditioning – speed, cyclic

Advantages of inverter air conditioners: myths and reality

So, according to the sales organizations, the inverter air conditioner:

  • Saves electricity
  • It works more quietly
  • Less harmful to health
  • More durable
  • More reliable than non-inverter

性禁区Below we analyze each item separately, what is true and what does not correspond to reality or is a clever marketing move.

Energy saving air conditioning in Dubai

性禁区Manufacturers of air conditioners promise energy savings when using an inverter up to 30%.

性禁区Unfortunately, all the studies are conducted by the manufacturers of refrigeration equipment themselves.

A very popular visual comparison scheme is the process of cooling and driving, which is not correct and does not reflect the essence of the process.

At the same time, an electronic unit appears in the inverter air conditioner, which is not found in a conventional air conditioner.

In the inverter module, some of the electricity is lost, which is converted into heat.

The volume of losses is clearly visible in the size of the radiator, which is installed to remove heat in the outdoor unit.

In any case, even with a maximum savings of 30%, taking into account the cost of electricity, and the difference in the cost of inverter and classic air conditioners, the payback period is more than three years.

性禁区When using the air conditioner only in summer in cooling mode, for a short period of time, the payback period increases.

性禁区For European countries, the period is shortened due to higher tariffs for electricity, so inverter air conditioners are more popular there.

If the air conditioner breaks, the payback period may move for an indefinite period due to the high cost of the .

Inverter air conditioners have low noise

性禁区Split system consists of two blocks – internal and external, we consider them separately.

Indoor unit:

性禁区It is located indoors and its noise level does not depend on the way the compressor is controlled (as it is located in the outdoor unit outside).

性禁区The noise produced by the air conditioner depends on the flow rate of the exhaust air and the aerodynamic qualities of the fan impeller and the casing.

That is, the noise level of the indoor unit depends on the specific model of the air conditioner, but not on the inverter control of the compressor.

To reduce the noise level, manufacturers use a special profile of the fan impeller and the shape of the outlet.

性禁区It often happens that cheap Asian inverters are noisier compared to branded non-inverter models of air conditioners.

External unit:

In modern air conditioners are installed so quiet compressors that the main noise creates a fan.

性禁区Fan operation is also independent of compressor control technology.

An air conditioner that is malfunctioning or improperly mounted can vibrate and make noise, for example, when a fixing bolt has fallen into a reinforcement in a concrete wall and directly transmits sound and vibrations to it.

性禁区Read more about the causes of air conditioning noise here .

Air Conditioners life

As the manufacturers and trading organizations promise, the average service life of an inverter air conditioner is about two times longer than an inverter air conditioner and is 8-15 years (different companies have different information).

The service life of the air conditioner is increased by increasing the service life of the compressor, since the number of starts in the inverter air conditioner is reduced and there are no high starting currents, which reduces compressor wear.

性禁区And now let’s remember the old Soviet refrigerators – for many they worked for twenty years, and the compressors felt quite normal.

You can still remember the air conditioners BC – Baku window-sill, they can now be seen in working condition.

And imported air conditioners of the O-general, Super General, Daikin,, Toshiba or Sanyo brands, imported at the beginning of the restructuring, are discarded during repairs only because of their unsightly appearance. But they worked according to the classical scheme, without an inverter converter.

性禁区So the conclusion suggests itself, air conditioner compressors are very reliable and durable devices, of course, if they are made at a factory of a well-established company.

But the compressor may fail due to poor installation:

  • When moisture enters the cold compartment, an acid is formed that destroys the insulation of the engine
  • In case of oil leakage, the compressor will operate without lubrication.

Or in the absence of service:

  • The compressor will operate under reduced pressure if it is not refueled in time.
  • The compressor can operate at elevated pressure and load if the heat exchangers are not cleaned in time.

性禁区It does not matter whether the inverter air conditioner or normal, the compressor will break in that and in another case.

Another factor affecting the service life of an air conditioner is that the inverter ac性禁区 has additional electronic cards – a power board that provides power conversion and compressor power, and a control card that provides communication with the indoor unit and control of the power unit.

The boards may break due to overvoltage or due to overheating of the power module, the protection does not always cope with its function.

Often, electronics is a weaker link than a compressor.

Inverter air conditioners accurately maintain the room temperature

Due to the change in compressor performance, the inverter air conditioner is able to quite accurately maintain the set air temperature.

But there is one “but.” The process of cooling the air in the room has a certain inertia, that is, it takes some time to cool it.

Now imagine any office, the air conditioner is working, the door has opened – a client has come, a kettle has been turned on, a computer has been turned off, someone has opened a window.

Naturally, temperature stability is out of the question.

Of course, another thing is a bedroom or children’s room, in these rooms the inverter can quite accurately maintain the temperature.

Disadvantages of inverter air conditioners

  • High price
  • Break more often
  • Expensive parts and long delivery time

Inverters electronic filling is completely different, and from time to time fails.

The cost of the boards is from 10 000 p., Which is comparable to the cost of some non-inverter air conditioners, plus the cost of replacing the board. Repairing the board is not always possible due to the fact that manufacturers use power modules that are not commercially available.

It is because of the inverter electronics that are less reliable than conventional air conditioners, this is especially true for Russia, where the quality of the mains supply is very unstable.

But technologies do not stand still and maybe soon the inverter will completely replace the old type air conditioners.

性禁区In addition, all new technologists who appear are used primarily in inverter models – economical compressors with DC motors, twin-rotor compressors, with extremely low vibration levels, swing rotor compressors, with reduced friction force, fan blades with a special low-noise profile and etc.

Which air conditioner to choose, inverter or classic?

An inverter air conditioner is more suitable for a bedroom, as its another advantage is in partial power mode, temperature maintenance, the air temperature at the exit from the indoor unit is higher than from the usual one, which reduces the risk of a cold from the air conditioner.
The choice of the type of air conditioner depends on the goals, that is, what room it will cool.

性禁区But in the premises with a short-term stay of people or with uneven and abrupt heat leakage all the advantages of the inverter are lost.

Since inverters are technically more complex products, the price for them is obviously higher.

With a limited budget, the best choice would be to purchase a non-inverter air conditioner of middle or higher class than an inverter split-system of low level.

Since the technical characteristics of such air conditioners are better, and the reliability is even more so.

Therefore, the choice is yours, but you must not forget that the more expensive the air conditioner, the more expensive its repair.

Application area Recommended air conditioning Note
Bedroom Inverter Less risk of catching cold
Kitchen Non inverter All the advantages of inverters become invisible.
Office Non inverter 性禁区The design look is not important;

The noise of any air conditioner is blocked by the office noise;

The acquisition of an inverter will not have time to pay off, for example, it will break or the office will change the place of rent.

The shops Non inverter No matter the appearance and noise characteristics
Server Non inverter In an emergency it is easier to repair and quickly find analog parts.

Troubleshooting Guide

Problem性禁区: The motor is heard operating but the air-conditioner dose not work when the indoor unit is powered on

Cause: Since the air-conditioner is powered on, it will come to working condition as long as you press the ON/OFF button of the remote control and the signal is well received.

Problem: The compressor stops running but the indoor fan motor keeps working when it is at cooling mode with the indoor temperature higher than set temperature.

性禁区Cause: If you turn off the air-conditioner and restart it immediately, it will return to normal in 3 minutes, after that, the air-conditioner will automatically adjust the indoor fan speed to what you set.

Problem: The compressor works discontinuously at dehumidifying mode.

性禁区Cause: The air-conditioner will automatically control the working of the compressor according to the inside temperature

Problem性禁区: The air-conditioner dose not work while the LED display is on.

Cause: The TIMER is set with the air-conditioner,it will be in hold on condition. If the TIMER setting is cancelled, the air-conditioner will return to normal working condition.

Problem性禁区: The compressor works discontinuously at cooling and dehumidifying mode, and the indoor fan motor slows down.

性禁区Cause: The compressor stops internally or the fan motor slows down to prevent the indoor heat exchanger from being frozen.
