We clean the condensate tray and drain separately with a descaling product, as they often 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 for air conditioning use, which eliminates residual bacteria and mould without leaving hazardous chemical residues. The next step is cleaning the coil, the component with thousands of thin fins through which the refrigerant circulates. We apply a specific descaling product for air conditioning and let it act for 15-20 minutes, depending on the level of dirt. We rinse it 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: excessive pressure bends the fins and reduces performance; insufficient pressure doesn't remove dirt. Yes, we use certified products for domestic air conditioning systems. They are non-toxic and leave no chemical residues in the air after rinsing and drying.

The most concerning aspect isn't the smell itself, but what it signifies. The volatile compounds produced by these growing microorganisms are respiratory irritants and can cause headaches, nasal congestion, throat irritation, and worsen asthma in sensitive individuals or those with allergies. Children and the elderly are particularly susceptible. What you breathe every time the air conditioning is on is air that has passed through the colonised coil. Air conditioning units 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% for much of the year, keeping the coil constantly exposed to condensation. Secondly, Sahara dust arriving each summer leaves a thin but sticky layer that adheres to the fins and traps other contaminants. Thirdly, sea air with suspended particles laden with salts contributes extra organic material to the filter. After deep sanitisation, the perceptible effects are immediate. The unpleasant odour disappears from the first use. The unit recovers between 10% and 25% of its original cooling performance (because a clean coil transfers heat better). Electricity consumption decreases proportionally to the recovered performance. Respiratory symptoms in sensitive individuals are clearly reduced or eliminated.

2-3 hours per standard indoor unit. For multi-splits, add 1-2 hours per extra unit. We use protective materials to avoid mess. The second most common service is electrical maintenance in industrial estates. This includes replacing main fuse boxes in warehouses, installing LED lighting in offices and production areas, and maintaining three-phase electrical installations for small and medium machinery. For specific heavy machinery, we coordinate with the manufacturer's specialised technical service. The typical residential client is a Spanish resident from a working or middle-class background. The typical industrial client is a small or medium-sized business owner or manager, with professional judgment to assess the technical quality of the work and high demands regarding deadlines. We adapt our service according to the context.

The price for equipment relocation in La Prosperitat typically ranges between €139 and €1638. The final figure depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. We offer a 30-day warranty on the service. If the odours return, we will repeat the service at no extra cost. Call us, message us on WhatsApp, or request your quote online – we'll respond in under 10 minutes during business hours.
