Users can clean the plastic mesh filters of the indoor unit themselves, without a technician. In residential apartments, washing them under running water is recommended 1 to 2 times a month (especially during periods of active use). However, the deep chemical cleaning of the internal radiator, turbine, and outdoor unit should be left to a professional once a year.

Ventilation system maintenance includes checking the amperage of electric motors, inspecting the airtightness of air ducts, testing valves (dampers), and cleaning the fan blades. Routine servicing prevents major breakdowns, which for commercial facilities (restaurants, hotels, clinics) is equivalent to a complete halt in business operations.

Unlike conventional models, an inverter air conditioner does not constantly cycle on and off — it smoothly adjusts the motor speed to maintain the required temperature. This saves between 30% and 50% on electricity and extends the lifespan of the appliance. Its servicing requires a more highly qualified technician, as its electronic control board is significantly more complex.
