Yes, we use certified products for domestic air conditioning. They are non-toxic, leaving no chemical residues in the air after rinsing and drying. The next step is cleaning the coil, the component with thousands of thin fins through which the refrigerant circulates. We apply a specific descaling product for air conditioning systems 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 sheeting to prevent water from entering where it shouldn't. The correct technique requires experience: too much pressure can bend the fins and reduce efficiency, while too little won't remove the dirt. We clean the condensate drain pan and the drain pipe 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, which eliminates residual bacteria and fungi without leaving hazardous chemical residues.

This is 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 conditioning after the winter or after several weeks of disuse, a damp, mouldy, or unpleasant organic smell emerges that lingers in the room for hours. The cause is biological. The indoor coil of the air conditioner collects 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. 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% for a large part of the year, keeping the coil constantly exposed to condensation. Secondly, the Saharan dust that arrives each summer leaves a thin but sticky layer that adheres to the fins and traps other pollutants. Thirdly, the sea air with suspended particles laden with salts contributes extra organic material to the filter. After a deep sanitisation, the noticeable effects are immediate. The unpleasant odour disappears from the very first use. The unit regains between 10% and 25% of its original cooling performance (because 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.

2-3 hours per standard indoor unit. For multi-split systems, add 1-2 hours per extra unit. We use protective materials to avoid making a mess. 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 typically require more maintenance. Mitsubishi Electric, Daikin, and LG are the three premium brands we install most frequently. Their inverter technology is highly mature, and they consume 40% less energy than older fixed-speed air conditioners to produce the same cooling effect. Their outdoor noise level is noticeably lower, which is important in communal courtyards where neighbours might complain. Their filters are of better quality and last longer between cleanings.

The price for a heat pump in Eixample (Mataró) typically ranges between €160 and €1440. The final amount depends on the property's condition, materials used, and the time required for the job.
