We clean the condensate tray and drain separately with descaling product as they tend to 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, 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 does not remove the dirt. Yes, we use certified products for domestic air conditioning. They are non-toxic, leaving no chemical residues in the air after rinsing and drying.

This is 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, an unpleasant smell of dampness, mould, or something organic is emitted, which lingers in the room for hours. The cause is biological. The internal coil of the air conditioner condenses moisture every time the unit cools. This constant moisture, combined with organic dustEntering through the filters and the moderate internal temperature when the unit is off, creates the perfect environment for bacterial and fungal colonies to grow. 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, the 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 laden with salts contributes extra organic material to the filter. After a thorough sanitisation, the noticeable effects appear immediately. The unpleasant odour disappears from the first use. The unit recovers between 10% and 25% of its original cooling performance (as a clean coil transfers heat more effectively). Electricity consumption decreases proportionally to the performance recovered. And respiratory symptoms in sensitive individuals are clearly reduced or disappear.

2-3 hours per standard indoor unit. For multi-splits, add 1-2 extra hours per additional unit. We work with protective materials to avoid stains. Manufacturer's official warranty (3-5 years) plus our 30-day labour coverage. Toshiba, Panasonic, and Fujitsu are a step below in price but not significantly in quality. They are a good option for tighter budgets. More economical brands like Samsung, Hisense, or basic Hitachi function correctly for the first four or five years, but their efficiency and durability are lower, and they usually require more maintenance.

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