The next step is cleaning the coil, the part with thousands of thin fins through which the refrigerant gas flows. We apply a specific descaling product for air conditioning and let it act for 15-20 minutes, depending on the degree of dirt. We rinse with moderately pressured 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 doesn't remove the dirt. We clean the condensate drain pan and the drain separately with 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 most concerning aspect is not 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 worsen asthma. Children and the elderly are particularly sensitive. What you breathe every time the air conditioning is on is the air that has passed through the colonised coil. After a deep sanitisation, the noticeable effects are immediate. The unpleasant smell disappears from the very first use. The unit recovers between 10 and 25 percent 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 significantly reduced or eliminated. 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 percent for much of the year, which keeps the coil constantly exposed to condensation. Secondly, Saharan dust that arrives each summer leaves a thin but sticky layer that adheres to the fins and traps other contaminants. Thirdly, the sea air with suspended particles charged with salts adds extra organic material to the filter.

2-3 hours per standard indoor unit. For multi-splits, add 1-2 hours per extra unit. We use protective materials to avoid stains. Manufacturer's official warranty (3-5 years) plus our 30-day labour guarantee. The second detail is the gas charge. The quantity must be exactly as specified by the manufacturer for the installed pipe length. Even a gram more or less won't be noticeable immediately, but accumulated over 5 years, it results in performance loss. The charge is always done using a precise electronic scale, not by estimating pressure as some quick installers do.

The cost of a gas recharge in La Barceloneta typically ranges between €126 and €1602. The final figure depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. 30-day warranty on the service. If the odours return, we'll repeat the service at no extra cost.
