We clean the condensate tray and drain separately with an descaling product as they often accumulates limescale. If the drain is partially blocked, we unblock 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 next step is cleaning the coil, the part with thousands of thin fins through which the refrigerant gas flows. We apply a specific air conditioning descaling product, letting 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 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.

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, in sensitive individuals or those with allergies, can cause headaches, nasal congestion, throat irritation, and worsen 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 thorough sanitisation, the noticeable effects are immediate. The unpleasant odour disappears from the first use. The unit recovers between 10 and 25 percent of its original cooling performance (because a clean coil transfers heat better). Electricity consumption decreases proportionally to the recovered performance. And respiratory symptoms in sensitive individuals are significantly reduced or disappear entirely. 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 percent for much of the year, meaning the coil is constantly exposed to condensation. Secondly, the Saharan dust that arrives 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.

2-3 hours per standard indoor unit. For multi-splits, add 1-2 hours per extra unit. We work with protective materials to avoid stains. Manufacturer's official warranty (3-5 years) plus our 30-day labour guarantee. Daikin, Mitsubishi Electric, and LG are the top three premium brands we install most often. Their inverter technology is highly mature, and they consume 40 percent less than older fixed-speed air conditioners to produce the same amount of cooling. Their outdoor noise levels are significantly lower, which is important in shared courtyards where neighbours might complain. Their filters are of better quality and last longer between cleanings.

The price for a gas refill in Sants typically ranges between €126 and €1602. The final amount 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. Daikin, Mitsubishi Electric, LG, Toshiba, Hitachi, Panasonic. For rooftop units: Carrier, York, Lennox. Selection based on power, budget, and availability.
