Yes, we use certified products for domestic air conditioning. They are non-toxic, leaving no chemical residue in the air after rinsing and drying. We clean the condensate tray and drain 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 for air conditioning use that 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, letting it act 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.

After a deep sanitisation, the perceptible effects appear immediately. The unpleasant odour disappears from the first use. The unit recovers 10-25 percent of its original cooling performance (because a clean coil transfers heat better). Electricity consumption decreases in proportion to the performance recovered. And respiratory symptoms in sensitive individuals are clearly reduced or disappear. The most concerning 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 air that has passed through a colonised coil. This is one of the most common problems with 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 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 constant 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 staining. Yes, it is mandatory in Spain for any handling of refrigerant gas. Without it, the manufacturer's warranty is voided and the installation may be deemed 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 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 in Llefià 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 repeat the service at no extra cost. Without measuring the copper, inspecting the facade, and assessing the electrical panel, we cannot provide an honest quote. The visit is free and without obligation.
