We clean the condensate tray and drain separately with a descaling product as they often have limescale build-up. 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 fine fins through which the refrigerant circulates. We apply a specific descaling product for air conditioning and let it sit 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 performance; too little doesn't remove the dirt. Yes, we use certified products for domestic air conditioning. They are non-toxic, leaving no chemical residues in the air after rinsing and drying.

After a deep sanitisation, noticeable effects appear immediately. The unpleasant smell disappears from the first use. The unit recovers between 10 and 25 percent of its original cooling performance (as a clean coil transfers heat better). Electricity consumption decreases proportionally to the recovered performance. And respiratory symptoms in sensitive individuals are clearly reduced or disappear. The most worrying 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 worsen asthma. 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 with domestic air conditioning on the Costa Blanca, and 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 unpleasant and organic emerges, 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 bacteria and fungi 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 handling of refrigerant gas. Without it, the manufacturer's warranty is voided, and the installation can be declared illegal. Toshiba, Panasonic, and Fujitsu are a step below in price but not significantly in quality. They are a good option for tighter budgets. More economical brands like Samsung, Hisense, or basic Hitachi models function correctly for the first four or five years, but their efficiency and durability are lower, and they tend to require more maintenance.

The price for a heat pump installation in La Prosperitat typically ranges between €160 and €1440. The final amount depends on the property's condition, materials used, and labour time. We always provide a fixed quote before starting. 30-day warranty on the service. If the odours return, we will repeat the service at no extra cost. Without measuring the copper, checking the facade, and assessing the electrical panel, we cannot provide an honest quote. The visit is free and without obligation.
