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 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 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 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.

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, keeping the coil constantly exposed to condensation. Secondly, the Sahara dust that arrives every summer leaves a thin but sticky layer that adheres to the fins and traps other contaminants. Thirdly, the sea air with suspended particles loaded with salts adds extra organic material to the filters. 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 susceptible. What you breathe every time the air conditioner is on is that air passed through a colonised coil. It's one of the most common problems in domestic air conditioning on the Costa Blanca, and almost no one knows why it happens. When you turn on the air conditioner after winter or after several weeks of disuse, a damp, mouldy, or unpleasant organic smell emerges that lingers in the room for hours. The cause is biological. The indoor coil sweats 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 bacterial and fungal colonies to grow.

2-3 hours per standard indoor unit. For multi-splits, add 1-2 hours per extra unit. We use protective material to avoid stains. Manufacturer's official warranty (3-5 years) plus our 30-day coverage on labour. Yes, it is mandatory in Spain for any handling of refrigerant gas. Without it, the manufacturer's warranty is voided, and the installation may be declared illegal.

The price for gas recharging in Montcada i Reixac 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.
