The condensate tray and drain are cleaned separately with a 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 product for air conditioning use, which eliminates residual bacteria and fungi without leaving hazardous chemical residues. The next step is cleaning the coil, the part with thousands of thin fins through which the refrigerant gas circulates. We apply a specific descaling product for air conditioning, let it work 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 efficiency, too little doesn't remove the dirt. Yes, we use certified products for domestic air conditioning. Non-toxic, with no chemical residues in the air after rinsing and drying.

After a deep sanitisation, the noticeable effects appear immediately. The unpleasant odour disappears from the first use. The unit recovers between 10 and 25 percent of its original cooling performance (because the clean coil transfers heat better). Electricity consumption decreases in proportion to the recovered performance. And respiratory symptoms in sensitive individuals clearly reduce or disappear. 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 comes out, 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 constant humidity, combined with the organic dust entering through the filters and the moderate indoor temperature when the unit is off, creates the perfect environment for bacteria and fungi colonies to grow. 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 worsening of asthma. Children and the elderly are particularly sensitive. What you breathe every time the air conditioner is on is that air passed through the colonised coil.
