We clean the condensate tray and drain separately with a descaling product as they often have accumulated 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 fine fins through which the refrigerant circulates. We apply a specific descaling product for air conditioning and let it act for 15-20 minutes, depending on the level of dirt. We then rinse with moderately pressured water, 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, with no chemical residues in the air after rinsing and drying.

After a deep sanitisation, noticeable effects appear immediately. Unpleasant odours disappear from the first use. The unit recovers between 10% and 25% of its original cooling performance (because a clean coil transfers heat better). Electricity consumption decreases in proportion to the recovered performance. And respiratory symptoms in sensitive individuals are clearly reduced or disappear. What is most concerning is not 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 worsening of 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 with 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 internal coil of the unit condenses moisture every time it cools. This permanent 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 bacterial and fungal colonies to grow.

2-3 hours per standard indoor unit. For multi-split systems, 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 below in price but not significantly in quality. They are a good option for tight 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 usually require more maintenance.

The price for a heat pump installation in La Verneda i la Pau typically ranges between €160 and €1440. The final amount depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. 30-day warranty on the service. If the odours return, we'll repeat the service at no extra cost. Without measuring the copper, inspecting the facade, and evaluating the electrical panel, we cannot provide an honest quote. Free, no-obligation visits.
