Non-toxic, with no chemical residue in the air after rinsing and drying. We clean the condensate drip tray and drain separately with a descaling product as 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 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, Saharan dust arriving each summer leaves a thin but sticky layer that adheres to the fins and traps other pollutants. Third, sea air with suspended particles charged with salts contributes extra organic material to the filter. The most worrying aspect isn't the smell 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 asthma exacerbation. Children and the elderly are particularly susceptible. What you breathe every time the air conditioner is on is the air that has passed through the colonised coil. 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, a smell of dampness, mould, or something unpleasant and organic emerges, lingering in the room for hours. The cause is biological. The indoor coil condenses moisture every time the unit cools. This permanent moisture, combined with organic dust entering through the filters and the moderate indoor temperature when the unit is off, creates a 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 use protective materials to avoid stains. Yes, it is mandatory in Spain for any handling of refrigerant gas.

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.
