Frequently Asked Questions

Is air conditioner maintenance and clean necessary?


It is essential to maintain the air conditioning equipment with the highest level of hygiene. Dirt encourages the growth of aerobes and fungi, these being the cause of diseases such as allergies, headaches, etc., which will be transmitted through the air and spread throughout the air outlet. Schillair is committed to safety standards in every cleaning that it carries out for air conditioning ducts, as well as air conditioning, ducting, in houses, offices or industrial buildings, kitchens and extraction hoods.

How often should I have my air conditioner maintained and cleaned?

In general, preventive maintenance and cleaning for air conditioners is carried out once a year.

This is because it gets dirty with use (internal filter, internal coil, external filter, turbine, etc.), as well as checking the refrigerant gas pressure. If it is low, not only should it be recharged, but more importantly, the system should be checked for leaks.

One of the main consequences of lack of maintenance is loss of performance. A related one is that the equipment starts to freeze.

It is possible that if it is used excessively (8 or more hours a day), it may need to be checked more often, and, in contrast, if it is used very little, you can wait a maximum of 2 years. You should never let more than this time pass for maintenance, as you will be putting the whole system at risk for something that may cost very little money in comparison.

Why should I maintain & clean my air conditioner ?
  1. For the comfort of customers and employees.
  2. For you and your family’s comfort
  3. To extend the life of the equipment.
  4. To increase system performance.
  5. For savings in energy costs.
  6. To increase hygiene and thus prevent the growth of aerobes and fungi.
  7. To remove dirt and reduce microbial contamination in the air.
  8. For compliance with current standards.
What are some of the problems caused by lack of maintenance?

These are some of the main problems that an air conditioner can have:

  1. Equipment out of gas due to a leak or failure to refill.
  2. Water flow noise during operation.
  3. The compressor does not heat.
  4. The unit does not turn on.
  5. The compressor does not start. This is observed because the compressor does not make any sound, the power supply does not reach the compressor or is insufficient.
  6. Improper electrical connections. This is usually due to common problems such as a cable that does not fit properly into the socket or poor condition of a pipe.
  7. Compressor failure.
  8. The equipment does not cool (this is a very common fault).
  9. Low voltage or incorrect voltage.
  10. Thermal protector different from the one specified.
  11. Water dripping from front panel.
  12. Defective thermostat or temperature sensor.
  13. Problems with circuit sizing (amps).
  14. Instantaneous gas in liquid line.
  15. Improper piping design. This may be due to high vertical height.
  16. Equipment turns on and off frequently.
  17. Contamination in the system. Moisture in the system can be due to a number of different cases.
  18. Failure of the power element or loss of charge.
  19. Low condensing pressure. For air-cooled condensing units, occurs when the pressure control system is faulty or incorrectly set.
  20. Unit does not turn on. This may be due to the unit not being fully plugged in, the
  21. circuit breaker is tripped or, as a major fault, the fuse is blown.
  22. Refrigerant or oil overload.
  23. Excessive oil accumulation in the evaporator.
  24. It is recommended that cleaning is not carried out by an untrained person.


Can I clean the air conditioner myself?

You should always contact a qualified and trained professional, because if you make a mistake you are putting the integrity of the appliance at risk, and your own health or that of the person in charge at risk.

We must not forget that we are dealing with electric current and as such, it must be respected.

If you are planning to use it this WINTER, we recommend that you contact a professional in the field for advice. In case you are looking to repair it because you detect a fault, you can also make contact us to specify what is happening.
