The condensate tray and drain are cleaned 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 product for air conditioning use that eliminates residual bacteria and fungi without leaving hazardous chemical residues.

After a deep sanitisation, perceptible effects appear immediately. Unpleasant odours disappear from the first use. The unit recovers between 10 and 25 percent of its original cooling capacity (as clean coils transfer heat better). Electricity consumption decreases proportionally to the recovered performance. And respiratory symptoms in sensitive individuals are clearly reduced or disappear. The most concerning 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 worsening asthma. Children and the elderly are particularly susceptible. What you breathe every time the air conditioner is on is the air passed through the colonised coils. This is one of the most common problems in domestic air conditioning on the Costa Blanca, and very few people know why it happens. When you turn on the air conditioner after winter or after several weeks of disuse, a smell of dampness, mould, or something unpleasantly organic emanates and lingers in the room for hours. The cause is biological. The internal coils of the air conditioner condense moisture every time the unit cools. This constant humidity, combined with organic dust entering through the filters and the moderate indoor temperature when the unit is off, creates the perfect environment for bacteria and mould colonies to grow.

2-3 hours per standard indoor unit. For multi-splits, add 1-2 hours per extra unit. We use protective materials to avoid making a mess. Yes, it is mandatory in Spain for any refrigerant gas handling. Without it, the manufacturer's warranty is void, and the installation may be declared illegal. Toshiba, Panasonic, and Fujitsu are a step below in price but not significantly in quality. They are a good option for tight budgets. More economical brands like Samsung, basic Hisense, or 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 a gas recharge in Cerdanyola del Vallès typically ranges between €126 and €1602. The final amount depends on the property's condition, materials, and working time.
