We clean the condensate tray and drain separately with a descaling product because they often accumulate 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 harmful 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, leaving it to act for 15-20 minutes depending on the degree 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. First, the average relative humidity in coastal areas is 70-75 percent for much of the year, which keeps the coil constantly exposed to condensation. Second, the Saharan dust that arrives each summer leaves a thin but sticky layer that adheres to the fins and traps other contaminants. Third, the sea air with suspended particles laden with salts adds extra organic material to the filter. The most worrying thing is not the smell itself, but what it indicates. The volatile compounds produced by these microorganisms as they grow are respiratory irritants and, in sensitive individuals or those with allergies, can cause headaches, nasal congestion, throat irritation, and worsening of asthma. Children and the elderly are particularly sensitive. What you breathe every time the air conditioning is on is that air passed through the 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 conditioning after winter or after several weeks of disuse, a smell of dampness, mould, or something unpleasant and organic emerges that lingers in the room for hours. The cause is biological. The indoor coil of the air conditioner condenses moisture every time the unit cools. This permanent moisture, combined with the organic dust entering through the filters and the moderate indoor temperature when the unit is off, creates the perfect environment for colonies of bacteria and fungi to grow.

2-3 hours per standard indoor unit. Multi-splits, add 1-2 hours per extra unit. We work with 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 manipulation of refrigerant gas. Without it, the manufacturer's warranty is void, and the installation may be declared illegal.

The price for a gas recharge in Molins de Rei typically ranges between €126 and €1602. The final amount depends on the property's condition, materials, and work time. We always give a fixed quote before starting. 30-day warranty on the service. If the odours return, we repeat the service at no extra cost.
