AC not cooling in Dubai villa: DIY fix or call professional?« Back to Previous Page

Based on your description from Al Barsha, this is a classic scenario we see daily in Dubai villas, and I strongly advise against further DIY attempts. Cleaning the filter is good basic maintenance, but the fact that it's running non-stop without achieving the set temperature, coupled with a skyrocketing DEWA bill, points directly to a significant efficiency loss.

The most probable cause is indeed a refrigerant (gas) leak, which is NOT a simple top-up job. Under UAE regulations, specifically the DM Code of Practice, handling refrigerant is strictly for certified technicians due to its environmental impact and the need for specialized leak detection and recovery equipment. Simply adding gas without fixing the leak is illegal, wasteful, and will only temporarily mask the problem before it fails again, costing you more.

Other serious possibilities include a failed compressor, a blocked or frozen evaporator coil, or a malfunctioning expansion valve – all of which require professional diagnosis with tools like manifold gauges and amp probes.

Continuing to run a faulty AC unit in this state puts immense strain on the compressor, risking a complete burnout, which is a far more expensive repair. For a proper inspection and definitive repair, you need a certified professional.
