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, leaving it to 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. The condensate tray and drain are cleaned separately with 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 for air conditioning use that eliminates residual bacteria and fungi without leaving dangerous chemical residues.

It 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 start the air conditioning after winter or several weeks of disuse, an unpleasant damp, mouldy, or organic smell emerges that lingers in the room for hours. The cause is biological. The indoor unit coil condenses moisture every time the unit cools. This permanent humidity, combined with organic dust entering through the filters and the moderate internal temperature of the unit when it's off, creates the perfect environment for colonies of bacteria and fungi to grow. After a deep sanitisation, the perceptible effects appear immediately. The unpleasant smell disappears from the first start-up. The unit recovers between 10 and 25 percent of its original cooling performance (because a clean coil transfers heat better). Electricity consumption decreases proportionally 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 percent for much of the year, which constantly exposes the coil to condensation. Second, the Saharan 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 salt-laden particles provides extra organic material to the filter.

2-3 hours per standard indoor unit. Multi-splits, add 1-2 hours per extra unit. We work with protective materials to prevent stains. Professional cleaning is radically different from wiping grilles or vacuuming filters. The correct procedure requires completely dismantling the indoor unit. We start by removing the front casing and tray, which are washed separately with descaling detergent. Then we access the centrifugal fan with blades, where the most biofilm accumulates because air always passes through there. Each blade is cleaned individually with a brush and specific product. 30-day guarantee on the service. If odours return, we repeat at no extra cost.
