Air conditioning servicing should perform once a year, to keep your air conditioner in technically correct condition. The most suitable period for air conditioning service in spring, so you can be sure that the air conditioner will flow during the summer, when it is most needed, work properly.
Besides regular filter cleaning, it is necessary to perform an annual air conditioning servicing because only in that way does it perform complete disinfection and cleaning not only internally but also externally units.
Air quality as the most important factor for the user staying in the room depends on the quality and purity of the filter in the indoor unit of the air conditioner.
If you use the device in business premises, shops, smoky areas, you need to perform air conditioning servicing several times a year.

Air conditioning servicing procedure
Regular maintenance – filter washing
It is necessary to clean the filters and wash them at intervals of up to a month. This removes all dirt and microorganisms. Regular filter cleaning extends the life of the device.
Filter cleaning procedure – first, you need to remove the indoor unit cover. The lid is easy to remove. On the lid, there are openings for passaging air which you also need to wash.
Filters should wash by immersion in lukewarm water, into which you can immerse cleaning and disinfecting agent. So immersed, leave for up to 30 minutes, then rinse with jet water, dry, and return to the indoor unit. If the air conditioner uses some special filter, see instructions for cleaning it.
If you notice that the honeycomb is on the outdoor unit when cleaning the indoor unit dirty, it is necessary to clean and disinfect the complete device.
Outdoor unit servicing:
- blowing the condenser and cleaning with disinfectant, to avoid overloading the compressor,
- case washing,
- check the outdoor unitholder,
- system pressure check, and addition or replacement (depending on the type used Freon).
Optionally:
- disassemble the indoor unit to access the fan and clean it,
- put on a little freshener to neutralise the smell of the chemicals you used,
- replace the batteries on the remote control and set the clock on it,
- measure supply voltage and compressor current,
- inspect the protective strips around cables and pipes.
Characteristic failures of air conditioners and ways of their elimination

The air conditioner does not work
Probable reasons – ways of elimination
- The cable not included in electricity – plug the cable into an electrical outlet, main voltage.
- It is an interrupted contact network – check the entire electrical network and correctness electrical elements.
- Colour mismatch on the connecting cables, outdoor and indoor unit – connect correctly by colour.
- Some temperature factors are incorrect – replace them with recent ones.
- The compressor does not work – replace it with a new one.
- Increased vapour pressure or the condensing pressure shuts off protection on the compressor – drain part of the Freon, if any crowded installation, clean the filters and heat exchangers both units.
- In cooling or heating mode, room temperature is lower or higher than specified remote control – set the temperature for a few degrees lower or higher than the temperature in rooms.
The air conditioner does not cool (or heat)
- Reduced amount or missing refrigerant gas in the installation – fill the installation of the required amount of gas.
- Dirty filters inside units – clean filters.
- Dirty heat exchanger surfaces – clean surfaces.
- The compressor is without compression – replace it with a new one.
- The fault is four-speed solenoid valve – change the condenser or replace it with a new one.
- Clogged capillaries from mechanical parts, oil or moisture installation – clean and vacuum the installation, and fill it with new gas.
- The fan does not work on the outside (indoor) unit interrupted electric current burned out electric motor, broken fan fins – restore electrically power supply or replace the electric motor with new. Check for correctness fins and it’s easy turning.
- They are not open plastic air deflectors on the indoor unit due to a burned-out electric motor for their start-up or mechanical system failure – replace the electric motor fan or remove mechanical damage.
The water is running out
- Clogged drain hose – clean the drain hose.
- Improperly mounted hose for drainage – mount it correctly.
- The level not levelled unit – level it.
The remote control does not work
- Power cord not included inside the unit – plug in the power cord.
- When switching different positions and modes of operation, the air conditioner does not respond – wait three minutes later last stop compressor and if after then the air conditioner does not start, check electric plate in an indoor unit.
Air conditioners are good for health if used properly. Maintaining the same temperature and humidity can help heart patients and people who have problems with blood pressure. However, in air-conditioned spaces, except the temperature, flow, and humidity of the air must take into account o the microbiological quality of the air.
Perform air conditioning servicing regularly, because only in this way can you be sure of the quality of the air you breathe indoors.
