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 product 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 where the refrigerant gas 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 moderately pressured water, protecting the rest of the unit with plastic to prevent water ingress where it shouldn't be. The correct technique requires experience: too much pressure bends the fins and reduces performance; too little doesn't remove the dirt effectively. Yes, we use certified products for domestic air conditioning. They are non-toxic, leaving no chemical residues in the air after rinsing and drying.

This is one of the most common problems with domestic air conditioning on the Costa Blanca, and very few people know why it happens. When you turn on the air conditioning after winter or after several weeks of disuse, a smell of dampness, mould, or an unpleasant organic odour emerges, lingering in the room for hours. The cause is biological. The indoor coil of the air conditioner 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 bacteria and fungi colonies to grow. 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% 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, the sea air with suspended particles laden with salts contributes extra organic material to the filter. 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 (as 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.

2-3 hours per standard indoor unit. For multi-splits, add 1-2 hours per additional unit. We use protective materials to avoid stains. The typical residential client is a working or middle-class Spanish resident. The typical industrial client is the owner or manager of a small or medium-sized business, with professional judgement to assess work quality and high demands on deadlines. We adapt our service to the context. The second largest service volume is electrical maintenance in industrial estates. This includes replacing main switchboards 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.
