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 fungi without leaving hazardous chemical residues. The next step is cleaning the coil, the part 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 with moderate water pressure, protecting the rest of the unit with plastic sheeting to prevent water from entering where it shouldn't. The correct technique requires experience: too much pressure bends the fins and reduces efficiency, too little doesn't remove the dirt.

The most concerning aspect isn't the smell itself, 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 exacerbate asthma. 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. After a deep sanitisation, the noticeable 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 more effectively). Electricity consumption decreases proportionally to the recovered performance. And respiratory symptoms in sensitive individuals are clearly reduced or disappear entirely. 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, Saharan 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 loaded with salts contributes extra organic material to the filter.

2-3 hours per standard indoor unit. For multi-split units, add 1-2 hours per extra unit. We use protective sheeting to avoid mess. The second largest service we provide 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-sized machinery. For specific heavy machinery, we coordinate with the manufacturer's specialised technical service. The typical residential client is a working or middle-class Spanish resident. The typical industrial client is a small or medium-sized business owner or manager, with professional judgement to assess the technical quality of the work and high demands regarding deadlines. We adapt our service according to the context.

The price for relocating air conditioning units in Centre (L'Hospitalet) typically ranges between €139 and €1638. The final amount depends on the condition of the property, materials used, and time taken. We always provide a fixed quote before starting. We offer a 30-day guarantee on our service. If the odours return, we'll repeat the service at no extra cost. We have verified professionals available within 2 hours. Choose the service and request a quote from us.
