The next step is cleaning the coil, the part with thousands of thin fins through which the refrigerant gas circulates. We apply a specific descaling product for air conditioning, letting it act for 15-20 minutes depending on the dirt level. We rinse with moderate water pressure, protecting the rest of the unit with plastic to prevent water from entering unintended areas. 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 unblock it with a flexible hose. Finally, after drying all components, we apply a certified disinfectant product for air conditioning use, eliminating 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, Saharan dust arriving each summer leaves a thin but sticky layer that adheres to the fins and traps other pollutants. Thirdly, sea air with suspended particles loaded with salts contributes extra organic material to the filter. 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 conditioner after winter or after several weeks of disuse, a musty, mouldy, or unpleasant organic smell emerges that lingers in the room for hours. The cause is biological. The indoor coil condenses moisture every time the unit cools. This constant moisture, combined with organic dust entering through the filters and the moderate indoor temperature when the unit is off, creates the perfect environment for bacterial and fungal colonies to grow. What's most concerning isn't the smell but what it indicates. The volatile compounds produced by these growing microorganisms are respiratory irritants and, for sensitive individuals or those with allergies, can cause headaches, nasal congestion, throat irritation, and worsening of asthma. Children and the elderly are susceptible. What you breathe every time the air conditioner is on is that air passed through the colonised coil.

The second largest service volume is electrical maintenance in industrial estates. Replacement of main distribution boards in warehouses, installation of LED lighting in offices and production areas, maintenance of three-phase electrical installations for small and medium machinery. For specific heavy machinery, we coordinate with specialised manufacturer technical services. The typical residential client is a working or middle-class Spanish resident. The typical industrial client is a small or medium business owner or manager, with professional judgment to assess the technical quality of the work and high demands on deadlines. We adapt the service according to the context. 2-3 hours per standard indoor unit. For multi-splits, add 1-2 hours per extra unit. We use protective materials to avoid stains.
