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 systems, leaving it to act for 15-20 minutes depending on the level of dirt. We rinse with moderately pressured water, protecting the rest of the unit with plastic to prevent water from entering unintended areas. The correct technique requires experience: too much pressure bends the fins and reduces performance, too little won't remove the dirt. We clean the condensate drain pan and drain separately with descaling product, as they often 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 that eliminates residual bacteria and fungi without leaving hazardous chemical residues.

This is one of the most common problems in domestic air conditioning on the Costa Blanca, and almost no one knows why it happens. When you turn on the air conditioning after winter or after several weeks of disuse, a smell of dampness, mould, or something unpleasantly organic emerges and 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 constant moisture, combined with 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. After a deep sanitisation, the perceptible effects appear immediately. The unpleasant smell disappears from the very first use. The unit recovers between 10 and 25 percent 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 significantly reduce or disappear. Air conditioners on the Costa Blanca accumulate dirt significantly faster than in dry inland regions. Three factors combine. Firstly, the average relative humidity in coastal areas is 70-75 percent for a large part of the year, keeping the coil constantly exposed to condensation. Secondly, the Saharan dust that arrives every summer leaves a thin but sticky layer that adheres to the fins and traps other contaminants. Thirdly, the sea air with suspended particles loaded with salts contributes extra organic material to the filter.

2-3 hours per standard indoor unit. For multi-splits, add 1-2 hours per extra unit. We use protective materials to avoid staining. Official manufacturer's warranty (3-5 years) plus our 30-day guarantee on labour. 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 basic Samsung, Hisense, or 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 an air source heat pump in Sant Climent de Llobregat generally ranges between €160 and €1440 as an indicative reference. The final figure depends on the property's condition, materials, and labour time, and we always finalise it after seeing photos or —if you prefer— after an inspection, with no obligation. 30-day guarantee on the service. If the odours return, we'll repeat the service at no extra cost. Daikin, Mitsubishi Electric, LG, Toshiba, Hitachi, Panasonic. For rooftop units: Carrier, York, Lennox. Selection based on power, budget, and availability.
