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

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.

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.

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.

“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.

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

  • 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

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

  • the reason is the imbalance of the fan impeller

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

  • 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

  • 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

  • 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.

Air Conditioner Service

Air Conditioner Service in Dubai – How often to carry out it?

Dubai HVAC Inspections and maintenance of air conditioners should always be carried out by Air Conditioning Experts in Dubai with relevant qualifications and certificates. The Air Conditioning service company should be invited at least once a year.

The number of inspections per year depends on how many months the Air-con system is actually used. If the system is operated mainly in the summer period, then it is enough to clean it before and after the summer season, given that the Air Conditioning System is being cleaned, preserved and will wait for the new season. It is recommended to check the system (heating, ventilation, dehumidification modes) every 6 months. During viewing, not only cleans the air-conditioning system, but also checks the tightness of the installation, saves individual elements, All Done Ac Maintenance Dubai find possible malfunctions or leaks that can be immediately corrected. It is worth taking this opportunity to put on a professional air-conditioner service in Dubai. Air-conditioning Specialists are able to verify the correctness of all cooling parameters and prevent sudden Ac system failures. They will also check the pressure in the cooling circuits, the condition of the oil, the fan speed, tightness and permeability of the system. Regular inspection of the technical condition of the Air Conditioning System will give us a sense of security, and a graphic long life.

Complex cleaning of the air conditioner includes, in particular, disinfection of the evaporator by washing with fungicides and bactericidal preparations. The selection of other cleaning methods depends on the type of individual devices and installation channels. Mainly used in two ways – dry and wet. The first is a mechanical cleaning with a brush or a jet of compressed air, the second is with the help of chemicals and hot steam. Thanks to them, harmful bacteria and fungi spores are removed. 

A clean air conditioner is a guarantee for the correct operation of the entire system and affects our safety. Proper operation of the installed air conditioner is the basis of their maximum and long-term uninterrupted operation.
