The next step is cleaning the coil, the part with thousands of thin fins where the refrigerant gas circulates. We apply a specific descaling product for air conditioning, letting it act for 15-20 minutes depending on the degree of dirt. We rinse with moderate pressure water, protecting the rest of the unit with plastic to prevent water from entering where it shouldn't. The correct technique requires experience: too much pressure bends the fins and reduces performance, too little does not remove the dirt. We clean the condensate tray and drain separately with a descaling product because they often accumulate limescale. If the drain is partially blocked, we unblock it with a flexible hose. Finally, after drying all components, we apply a certified disinfectant product for air conditioning use that eliminates residual bacteria and fungi without leaving dangerous chemical residues. Yes, we use certified products for domestic air conditioning. Non-toxic, no chemical residues in the air after rinsing and drying.

The most worrying thing is not the smell but what it indicates. The volatile compounds produced by these microorganisms as they grow are respiratory irritants and, in sensitive people or those with allergies, can cause headaches, nasal congestion, throat irritation, and worsening of asthma. Children and the elderly are particularly sensitive. What you breathe every time the air conditioner is on is air passed through that colonised coil. After a deep sanitisation, noticeable effects appear immediately. The unpleasant smell disappears from the first start. The unit recovers between 10 and 25 per cent of its original cooling performance (because the clean coil transfers heat better). Electricity consumption decreases in proportion to the recovered performance. And respiratory symptoms in sensitive individuals are clearly reduced or disappear. Air conditioners on the Costa Blanca accumulate dirt significantly faster than in dry inland regions. Three factors combine. First, the average relative humidity in coastal areas is 70-75 per cent for much of the year, which keeps the coil constantly exposed to condensation. Second, the Sahara dust that arrives every summer leaves a thin but sticky layer that adheres to the fins and traps other contaminants. Third, the sea air with suspended particles loaded with salts introduces extra organic material into the filter.
