The most concerning 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 worsening asthma. Children and the elderly are particularly susceptible. What you breathe in every time the air conditioner is switched on is the air passed through the colonised coil. This is one of the most common problems with domestic air conditioning on the Costa Blanca, and hardly anyone knows why it happens. When you turn on the air conditioner after winter or after several weeks of disuse, it emits a musty, mouldy, or unpleasant organic smell that lingers in the room for hours. The cause is biological. The indoor coil of the air conditioner condenses moisture every time the unit cools. This permanent dampness, combined with organic dust entering through the filters and the moderate indoor temperature when the unit is off, creates a perfect breeding ground for colonies of bacteria and fungi. After a deep sanitisation, the noticeable effects are immediate. The unpleasant odour disappears from the very first use. The unit recovers between 10% and 25% of its original cooling performance (because a clean coil transfers heat more effectively). Electricity consumption decreases proportionally to the recovered performance. And respiratory symptoms in sensitive individuals are significantly reduced or disappear entirely.

Professional calculation considers all these factors and correctly sizes the equipment. The difference in quotes between a correctly sized and a poorly sized unit might seem significant at first. The actual cost is ultimately paid by the end customer visiting the shop or restaurant. A poorly air-conditioned premises loses customers in the summer when the heat becomes unbearable.
