Is dusty AC coil raising my DEWA bill?« Back to Previous Page

Yes, a dusty AC coil is absolutely a significant contributor to your higher DEWA bill. The scenario you've described is very common in Dubai, especially in areas like JVC that are exposed to high levels of ambient dust and sand.

The coil is the heart of your AC's heat exchange process. When it's caked with a thick layer of dust and grime, it acts as an insulator. The system has to work much harder and for longer periods to achieve the desired temperature. This directly translates to increased electricity consumption, which is reflected on your DEWA bill. Furthermore, the reduced airflow forces the compressor to run under excessive strain, potentially leading to premature and costly mechanical failures.

Given the current climate, with temperatures rising and humidity levels increasing, the demand on your unit will only intensify. A dirty coil also creates a damp environment perfect for microbial growth like mold and bacteria, which can be circulated into your living space, impacting indoor air quality.

For a case as you've described—visible, heavy buildup and a noticeable drop in performance—this requires urgent professional attention. DIY cleaning often fails to remove deeply embedded dirt and can risk damaging the delicate fins of the coil. Our technicians at Saniservice use specialized EPA-approved cleaning agents and high-pressure extraction systems to thoroughly degrease and sanitize the coils without causing damage, restoring efficiency and improving hygiene.

To properly diagnose the issue and prevent further energy waste and potential system damage, I recommend scheduling a professional inspection and cleaning.
