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, let it act for 15-20 minutes depending on the degree of dirt. We rinse with moderate water pressure, 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 doesn't remove the dirt. We clean the condensate tray and drain separately with descaling product as they tend to accumulate limescale. If the drain is partially blocked, we clear 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 hazardous chemical residues.

Air conditioners on the Costa Blanca accumulate dirt significantly faster than in dry inland regions. Three factors combine. Firstly, the average relative humidity in coastal areas is 70-75 percent for much of the year, keeping the coil constantly exposed to condensation. Secondly, the Saharan dust that arrives each summer leaves a thin but sticky layer that adheres to the fins and traps other pollutants. Thirdly, the sea air with suspended particles laden with salts contributes extra organic material to the filter. The most worrying aspect is not the smell but what it indicates. The volatile compounds produced by these growing microorganisms are respiratory irritants and, in sensitive individuals or those with allergies, can cause headaches, nasal congestion, throat irritation, and worsening asthma. Children and the elderly are susceptible. What you breathe every time the air conditioning is on is the air that has passed through the colonised coil. This is one of the most common problems in domestic air conditioning on the Costa Blanca, and almost no one knows why it happens. When you turn on the air conditioning after winter or after several weeks of disuse, a smell of damp, mould, or something unpleasant and organic emerges, lingering in the room for hours. The cause is biological. The internal coil of the air conditioner condenses moisture every time the unit cools. This constant moisture, combined with the organic dust entering through the filters and the moderate indoor temperature when the unit is off, creates the perfect environment for colonies of bacteria and fungi to grow.
