DEWA-certified AC repair urgent for grinding noise?« Back to Previous Page

Based on the symptoms you've described, this is an urgent situation. Choosing a DEWA-certified technician is not just a recommendation; it is an absolute necessity for this type of repair, especially in Dubai.

The grinding noise indicates a severe mechanical failure, most likely within the compressor or the fan motor bearings. This is a complex, sealed system that requires specialized training and equipment to service safely. A general handyman lacks the certification to handle the pressurized refrigerant gases (like R410A) legally and safely, which is a strict DEWA and Dubai Municipality regulation. Incorrect handling is a serious safety hazard and violates UAE environmental codes.

Furthermore, the warm air and high electricity bill confirm a catastrophic loss of efficiency. The system is working excessively hard to try and cool, destroying itself in the process and costing you a fortune. Only a certified technician can perform a proper diagnosis with tools like manifold gauges and leak detectors to identify the root cause, whether it's a refrigerant leak, compressor seizure, or electrical fault.

Attempting a cheap fix with an uncertified person will likely lead to further damage, void any existing manufacturer warranties, and result in even more costly repairs down the line. For a compressor issue, you're looking at a significant repair that must be done right.

Given the symptoms and the impending summer heat, I strongly recommend you stop running the unit immediately to prevent total failure and call a professional. For a certified assessment and repair, you can contact our team at 800-MOLDS or 800-66537.
