Non-toxic, with no chemical residues in the air after rinsing and drying. 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 product for air conditioning use that eliminates residual bacteria and fungi without leaving hazardous chemical residues.

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, keeping 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 charged with salts contributes extra organic material to the filter. The most worrying aspect isn't 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 worsen 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 coil. It's one of the most common problems in domestic air conditioning on the Costa Blanca, and almost nobody knows 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 unpleasant and organic emanates, lingering in the room for hours. The cause is biological. The internal 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. For multi-splits, add 1-2 hours per extra unit. We use protective materials to avoid stains. Yes, it is mandatory in Spain for any handling of refrigerant gas. Without it, the manufacturer's warranty is void, and the installation may be declared illegal. Toshiba, Panasonic, and Fujitsu are a step down in price but not too much in quality. They are a good option for tight budgets. More economical brands like basic Samsung, 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.
