The economical Ac Maintenance Service Dubai – (maintenance once a year)

Our Professionals once a year (usually in early spring) conduct a thorough cleaning and diagnostics of the air conditioner in Dubai. The air conditioner is tested in all operating conditions, a number of parameters are measured, on which the life of the air conditioner depends and the safety of its operation for the surrounding (Freon pressure in the system, the difference in temperatures at the inlet and outlet of the evaporator, leakage of the “phase” to the housing ,). Based on the results of the inspection, an inspection report is drawn up. In the event that the pressure in the Freon system is slightly different from the norm, which can be caused by an allowable leakage of Freon in 30-50 grams per year, a free charging of the air conditioner with Freon is performed. If more serious malfunctions are identified, a separate estimate is drawn up, which includes all the components and work required to repair the air conditioner. In this case, the repair of the air conditioner is carried out at the expense of the Customer. In the event that a malfunction is detected during the operation of the equipment by the Customer, the professionals of Al Naveed Ac System Installation L.L.C conduct the diagnosis of the air conditioner free of charge. Note that this option provides for periodic cleaning of the indoor unit filters by the Customer in accordance with the instruction manual.
