The next step is cleaning the coil, the component with thousands of thin fins through which the refrigerant gas circulates. We apply a specific descaling product for air conditioning and let it sit 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 unintended areas. The correct technique requires experience: excessive pressure bends the fins and reduces performance; too little pressure doesn't remove the dirt. We clean the condensate tray and 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 that eliminates residual bacteria and fungi without leaving hazardous chemical residues.

The most worrying aspect isn't the smell itself but what it indicates. 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 conditioner is on is air that has passed through the colonised coil. After a thorough sanitisation, the noticeable effects are immediate. The unpleasant odour disappears from the very first use. The unit regains between 10% and 25% of its original cooling performance (as a clean coil transfers heat more efficiently). Electricity consumption decreases proportionally to the recovered performance. And respiratory symptoms in sensitive individuals are significantly reduced or eliminated. 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 that arrives 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.

2-3 hours per standard indoor unit. For multi-splits, add 1-2 hours per extra unit. We use protective materials to avoid stains. Electronic boards can fail due to power surges, humidity, or component ageing. This is relatively common in areas prone to thunderstorms, like the Vega Baja interior in August. Repairs may involve replacing the entire board or, if identifiable, a specific capacitor or resistor. It depends heavily on the model and parts availability. For premium units from recognised brands (Mitsubishi, Daikin, LG) aged 10-12 years, repair is often still worthwhile as the overall quality justifies extending the lifespan. For basic units aged 7-8 years, replacement is almost always the more reasonable decision.

The price for a gas recharge in La Garriga typically ranges from €126 to €1602. The final cost depends on the property's condition, materials used, 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 charge. Older models without inverter technology start and stop abruptly at full power, putting more stress on the compressor. Modern inverter models modulate smoothly and last longer. Their electronics are more sensitive, and from the seventh or eighth year, board failures requiring replacement of the entire module start to occur. The decision between repairing and replacing the unit depends on the cost of the part versus the price of an equivalent new unit.
